Designs and variants
Spherical roller bearings have 2 rows of rollers, a common sphered outer ring raceway and 2 inner ring raceways inclined at an angle to the bearing axis.
The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for
example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
Factors influence spherical roller bearing performance
Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers,
raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces. Main factors which influence spherical roller bearing performance include, but are not limited to:
1.Symmetrical rollers
2.Roller tolerances
3.Special roller profile
4.Self-guiding rollers and a guide ring between the 2 rows of rollers
5.Metal cages
Basic design bearings
Depending on their series and size, standard spherical roller bearings are as following basic designs:
CC design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring. The CC design is indicated by the
designation suffix C or CC. Large CC design bearings with the designation suffix EC or ECC have an optimized internal design for increased load carrying capacity.
CA design bearings have a machined double prong-type brass cage, an inner ring with a retaining flange on both sides and a guide ring centred on the inner ring. The flanges
on the inner ring are designed to keep the rollers in place when swivelling the bearing during installation or maintenance. The flanges are not designed to guide the rollers
or accommodate any axial load. The CA design is indicated by the designation suffix CA. Large CA design bearings with the designation suffix ECA have an optimized internal design for increased load carrying capacity.
E design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm). They have an annular groove and 3 lubrication holes in the outer ring. E design bearings are indicated by the designation suffix E. All E design bearings have an optimized internal design for increased load carrying capacity.
Annular groove and lubrication holes
Spherical roller bearings are available with an annular groove and 3 lubrication holes in the outer ring (designation suffix W33) or 3 lubrication holes in the outer ring (designation suffix W20) . E design bearings have an annular groove and 3 lubrication holes as standard and therefore, the W33 designation suffix is not necessary
Cages
Cages in spherical roller bearings are an integral part of the bearing internal design. Depending on their internal design, series and size, spherical roller bearings are fitted with 1 of the cages . For additional information about the suitability of cages, refer to Cages and Cage materials .

Principle of Cycloidal Gearing
Cycloidal gearing is a mechanism that utilizes the unique shape of cycloidal discs to achieve motion transmission. The principle involves the interaction between two main components: the input disc and the output disc.
The input disc has lobes with pins, while the output disc has lobes with matching holes. The lobes on both discs are not perfectly circular but are shaped in a cycloidal profile. As the input disc rotates, the pins on its lobes engage with the holes in the output disc’s lobes.
As the input disc rotates, the pins move along the cycloidal paths, causing the output disc to rotate. The interaction between the pins and the holes results in smooth and continuous motion transfer. The unique shape of the cycloidal profile ensures that there is always at least one point of contact between the pins and the holes, allowing for efficient torque transmission and reduced wear.
Cycloidal gearing provides advantages such as high torque capacity, compact size, and precision motion. However, due to the complex shape of the components and the continuous engagement, manufacturing and assembly of cycloidal gearboxes can be intricate.

Calculation of Reduction Ratio in a Cycloidal Gearbox
The reduction ratio in a cycloidal gearbox can be calculated using the following formula:
Reduction Ratio = (Number of Input Pins + Number of Output Pins) / Number of Output Pins
In a cycloidal gearbox, the input pins engage with the lobes of the cam disc, while the output pins are engaged with the cycloidal pins of the output rotor. The reduction ratio determines the relationship between the number of input and output pins engaged at any given time.
For example, if a cycloidal gearbox has 7 input pins and 14 output pins engaged, the reduction ratio would be:
Reduction Ratio = (7 + 14) / 14 = 1.5
This means that for every 1 revolution of the input pins, the output rotor will complete 1.5 revolutions. The reduction ratio is a key parameter that influences the output speed and torque of the cycloidal gearbox.

Suitability of Cycloidal Gearboxes for High-Torque Applications
Cycloidal gearboxes are well-suited for high-torque applications due to their unique design and mechanical advantages. Here’s why they are suitable:
- Multiple Engagement Points: Cycloidal gearboxes have multiple teeth in contact at any given moment, distributing the load over a larger area. This reduces wear and stress on individual teeth, making them capable of handling high torque.
- High Load-Carrying Capacity: The design of the cycloidal mechanism, with its large number of pins and rollers, provides high load-carrying capacity. This makes them capable of transmitting significant torque without failure.
- Tight Tolerances: The precision and tight tolerances in the construction of cycloidal gearboxes ensure smooth and efficient power transmission even under heavy loads.
- Compact Design: Cycloidal gearboxes achieve high torque in a relatively compact size. This is particularly advantageous in applications where space is limited.
- High Gear Ratio: Cycloidal gearboxes can achieve high gear ratios, allowing them to convert lower input speeds into higher output torque, which is essential in high-torque applications.
These factors make cycloidal gearboxes a reliable choice for various high-torque applications across industries such as heavy machinery, robotics, material handling, and more.
History of Cycloidal Gear System Development
The history of cycloidal gear systems dates back to ancient times, with various forms of non-circular gears being used for specialized applications. The concept of the cycloidal gear system as we know it today, however, has evolved over centuries of engineering and innovation:
- Ancient Roots: The concept of using non-circular gears can be traced back to ancient civilizations, where devices like the “Antikythera Mechanism” (c. 150-100 BC) employed non-circular gear arrangements.
- Cam Mechanisms: During the Renaissance, engineers and inventors like Leonardo da Vinci explored mechanisms involving cams and followers, which are precursors to modern cycloidal gears.
- Cycloidal Motion Studies: In the 19th century, engineers and mathematicians like Franz Reuleaux and Robert Willis studied and developed mechanisms based on the principles of cycloidal motion.
- Early Cycloidal Gearboxes: The development of cycloidal gear systems gained momentum in the late 19th and early 20th centuries, with inventors like Emile Alluard and Louis André creating early forms of cycloidal gear mechanisms and gearboxes.
- Cycloidal Drive: The term “cycloidal drive” was coined by James Watt in the 18th century, referring to mechanisms that produce a motion resembling a rolling circle.
- Modern Cycloidal Gearboxes: The development of modern cycloidal gearboxes was further advanced by engineers like Ralph B. Heath, who patented the “Harmonic Drive” in the 1950s. This invention marked a significant step in the advancement and commercialization of precision cycloidal gear systems.
- Advancements and Applications: Over the decades, cycloidal gear systems have found applications in robotics, aerospace, automation, and other fields that require compactness, precision, and high torque capabilities.
The history of cycloidal gear system development reflects the contributions of many engineers and inventors who have refined and advanced the technology over time. Today, cycloidal gearboxes continue to play a crucial role in various industries and applications.
What is a Cycloidal Gearbox?
A cycloidal gearbox, also known as a cycloidal drive, is a type of gearing mechanism that utilizes the principle of cycloidal motion for power transmission. It consists of several components, including a high-speed input shaft, a set of cycloidal pins or rollers, and an outer stationary ring with lobed profiles.
The operation of a cycloidal gearbox involves a unique mechanism:
- Input Shaft: The high-speed input shaft is connected to the driving source, such as an electric motor. It transfers rotational motion to the cycloidal pins.
- Cycloidal Pins or Rollers: These pins or rollers are typically arranged around the input shaft in a circular pattern. As the input shaft rotates, the cycloidal pins also rotate, causing them to engage with the lobes on the outer stationary ring.
- Outer Stationary Ring: The outer ring has lobed profiles, and it remains stationary during operation. The lobes of the outer ring interact with the cycloidal pins or rollers, causing them to move in a unique motion known as epicycloidal or hypocycloidal motion.
The interaction between the cycloidal pins and the lobed profiles of the outer ring results in smooth and controlled motion transmission. The mechanism provides advantages such as high torque capacity, compact size, and precise positioning capabilities.
Cycloidal gearboxes are widely used in various applications, including robotics, automation, packaging machinery, and other industrial systems where high torque, precision, and compact design are essential.

Developing a Mathematical Model of a Cyclone Gearbox
Compared to planetary gearboxes, cycloidal gearboxes are often seen as the ideal choice for a wide range of applications. They feature compact designs that are often low friction and high reduction ratios.
Low friction
Developing a mathematical model of a cycloidal gearbox was a challenge. The model was able to show the effects of a variety of geometric parameters on contact stresses. It was able to model stiction in all quadrants. It was able to show a clear correlation between the results from simulation and real-world measurements.
The model is based on a new approach that enables modeling stiction in all quadrants of a gearbox. It is also able to display non-zero current at standstill. Combined with a good simulation algorithm, the model can be used to improve the dynamic behaviour of a controlled system.
A cycloidal gearbox is a compact actuator used for industrial automation. This type of gearbox provides high gear ratios, low wear, and good torsional stiffness. In addition, it has good shock load capacity.
The model is based on cycloidal discs that engage with pins on a stationary ring gear. The resulting friction function occurs when the rotor begins to rotate. It also occurs when the rotor reverses its rotation. The model has two curves, one for motor and one for generator mode.
The trochoidal profile on the cycloidal disc’s periphery is required for proper mating of the rotating parts. In addition, the profile should be defined accurately. This will allow an even distribution of contact forces.
The model was used to compare the relative performance of a cycloidal gearbox with that of an involute gearbox. This comparison indicates that the cycloidal gearbox can withstand more load than an involute gearbox. It is also able to last longer. It is also able to produce high gear ratios in a small space.
The model used is able to capture the exact geometry of the parts. It can also allow a better analysis of stresses.
Compact
Unlike helical gearing, compact cycloidal gearboxes can provide higher reduction ratios. They are more compact and less weighty. In addition, they provide better positioning accuracy.
Cycloid drives provide high torque and load capacity. They are also very efficient and robust. They are ideal for applications with heavy loads or shock loads. They also feature low backlash and high torsional stiffness. Cycloid gearboxes are available in a variety of designs.
Cycloid discs are mounted on an eccentric input shaft, which drives them around a stationary ring gear. The ring gear consists of many pins, and the cycloidal disc moves one lobe for every rotation of the input shaft. The output shaft contains roller pins, which rotate around holes in the cycloidal disc.
Cycloid drives are ideally suited to heavy loads and shock loads. They have high torsional stiffness and high reduction ratios, making them very efficient. Cycloid gearboxes have low backlash and high torque and are very compact.
Cycloid gearboxes are used for a wide variety of applications, including marine propulsion systems, CNC machining centers, medical technology, and manipulation robots. They are especially useful in applications with critical positioning accuracy, such as surgical positioning systems. Cycloid gearboxes feature extremely low hysteresis loss and low backlash over extended periods of use.
Cycloid discs are usually designed with a reduced cycloid diameter to minimize unbalance forces at high speeds. Cycloid drives also feature minimal backlash, a high reduction ratio, and excellent positioning accuracy. Cycloid gearboxes also have a long service life, compared to other gear drives. Cycloid drives are highly robust, and offer higher reduction ratios than helical gear drives.
Cycloid gearboxes have a low cost and are easy to print. CZPT gearboxes are available in a wide range of sizes and can produce high torque on the output axis.
High reduction ratio
Among the types of gearboxes available, a high reduction ratio cycloidal gearbox is a popular choice in the automation field. This gearbox is used in applications requiring precise output and high efficiency.
Cycloid gears can provide high torque and transmit it well. They have low friction and a small backlash. They are widely used in robotic joints. However, they require special tools to manufacture. Some have even been 3D printed.
A cycloidal gearbox is typically a three-stage structure that includes an input hub, an output hub, and two cycloidal gears that rotate around each other. The input hub mounts movable pins and rollers, while the output hub mounts a stationary ring gear.
The input shaft is driven by an eccentric bearing. The disc is then pushed against the ring gear, which causes it to rotate around the bearing. As the disc rotates, the pins on the ring gear drive the pins on the output shaft.
The input shaft rotates a maximum of nine revolutions, while the output shaft rotates three revolutions. This means that the input shaft has to rotate over eleven million times before the output shaft is able to rotate. The output shaft also rotates in the opposite direction of the input shaft.
In a two-stage differential cycloidal speed reducer, the input shaft uses a crank shaft design. The crank shaft connects the first and second cycloidal gears and actuates them simultaneously.
The first stage is a cycloidal disc, which is a gear tooth profile. It has n=7 lobes on its circumference. Each lobe moves around a reference pitch circle of pins. The disc then advances in 360deg steps.
The second stage is a cycloidal disc, also known as a “grinder gear”. The teeth on the outer gear are fewer than the teeth on the inner gear. This allows the gear to be geardown based on the number of teeth.
Kinematics
Various scholars have studied the kinematics of cycloidal gearbox. They have developed various approaches to modify the tooth profile of cycloidal gears. Some of these approaches involve changing the shape of the cycloidal disc, and changing the grinding wheel center position.
This paper describes a new approach to cycloid gear profile modification. It is based on a mathematical model and incorporates several important parameters such as pressure angle, backlash, and root clearance. The study offers a new way for modification design of cycloid gears in precision reducers for robots.
The pressure angle of a tooth profile is an intersegment angle between the normal direction and the velocity direction at a meshing point. The pressure angle distribution is important for determining force transmission performance of gear teeth in meshing. The distribution trend can be obtained by calculating the equation (5).
The mathematical model for modification of the tooth profile can be obtained by establishing the relationship between the pressure angle distribution and the modification function. The dependent variable is the modification DL and the independent variable is the pressure angle a.
The position of the reference point A is a major consideration in the modification design. It ensures the force transmission performance of the meshing segment is optimal. It is determined by the smallest profile pressure angle. The position is also dependent on the type of gear that is being modified. It is also influenced by the tooth backlash.
The mathematical model governing the pressure angle distribution is developed with DL=f(a). It is a piecewise function that determines the pressure angle distribution of a tooth profile. It can also be expressed as DL=ph.
The pressure angle of a tooth is also an angle between the common normal direction at the meshing point and the rotation velocity direction of the cycloid gear.
Planetary gearboxes vs cycloidal gearboxes
Generally, there are two types of gearboxes that are used for motion control applications: cycloidal gearbox and planetary gearbox. Cycloid gearboxes are used for high-frequency motions, while planetary gearboxes are suitable for low-speed applications. Both are highly accurate and precise gearboxes that are capable of handling heavy loads at high cycle rates. But they have different advantages and disadvantages. So, engineers need to determine which type of gearbox is best suited for their application.
Cycloid gearboxes are commonly used in industrial automation. They provide excellent performance with ratios as low as 10:1. They offer a more compact design, higher torque density and greater overload protection. They also require less space and are less expensive than planetary gearboxes.
On the other hand, planetary gearboxes are lightweight and offer a higher torque density. They are also capable of handling higher ratios. They have a longer life span and are more precise and durable. They can be found in a variety of styles, including square-framed, round-framed and double-frame designs. They offer a wide range of torque and speed capabilities and are used for numerous applications.
Cycloid gearboxes can be manufactured with different types of cycloidal cams, including single or compound cycloidal cams. Cycloid cams are cylindrical elements that have cam followers that rotate in an eccentric fashion. The cam followers act like teeth on the internal gear. Cycloid cams are a simple concept, but they have numerous advantages. They have a low backlash over extended periods of time, allowing for more accurate positioning. They also have internal compressive stresses and an overlap factor between the rolling elements.
Planetary gearboxes are characterized by three basic force-transmitting elements: ring gear, sun gear, and planet gear. They are generally two-stage gearboxes. The sun gear is attached to the input shaft, which in turn is attached to the servomotor. The ring gear turns the sun gear and the planet gear turns the output shaft.

A Mathematical Model of a Cycloid Gearbox
Having a gearbox with a cycloidal rotor is an ideal design for a car or any other vehicle, as the cycloidal design can reduce the amplitude of vibration, which is a key component in car performance. Using a cycloidal gearbox is also a great way to reduce the amount of friction between the gears in the gearbox, which can help to reduce noise and wear and tear. A cycloidal gearbox is also a very efficient design for a vehicle that needs to perform under high loads, as the gearbox can be very robust against shock loads.
Basic design principles
cycloidal gearboxes are used for precision gearing applications. Cycloidal drives are compact and robust and offer lower backlash, torsional stiffness and a longer service life. They are also suitable for applications involving heavy loads.
Cycloidal drives are compact in size and provide very high reduction ratios. They are also very robust and can handle shock loads. Cycloidal drives are ideally suited to a wide range of drive technologies. Cycloidal gears have excellent torsional stiffness and can provide a transmission ratio of 300:1. They can also be used in applications where stacking multiple gear stages is not desired.
In order to achieve a high reduction ratio, cycloidal gears must be manufactured extremely accurately. Cycloidal gears have a curved tooth profile that removes shear forces at any point of contact. This provides a positive fit for the gear disc. This profile can be provided on a separate outer bushing or as an internal gear profile insert.
Cycloidal drives are used in marine propulsion systems, where the load plate rotates around the X and Y axis. The plate is anchored by a threaded screw hole arranged 15mm away from the center.
A secondary carrier body is used in a cycloidal gearbox to support the load plate. The secondary carrier body is composed of a mounting carrier body and a secondary carrier disc.
Low friction
Several studies have been conducted to understand the static problems of gears. In this paper, we discuss a mathematical model of a low friction cycloidal gearbox. This model is designed to calculate various parameters that affect the performance of the gearbox during production.
The model is based on a new approach that includes the stiction effect and the nonlinear friction characteristic. These parameters are not covered by the conventional rule of thumb.
The stiction effect is present when the speed direction is changed. During this time, the input torque is required to prevail over the stiction effect to generate movement. The model also enables us to calculate the magnitude of the stiction effect and its breakaway speed.
The most important thing is that the model can be used to improve the dynamic behavior of a controlled system. In this regard, the model has a high degree of accuracy. The model is tested in several quadrants of the gearbox to find the optimum stiction breakaway speed. The simulation results of the model show that this model is effective in predicting the efficiency of a low friction cycloidal gearbox.
In addition to the stiction model, we also studied the efficiency of a low friction cycloidal reducer. The reduction ratio of this gearbox was estimated from the formula. It is found that the ratio approaches negative infinity when the motor torque is close to zero Nm.
Compact
Unlike standard planetary gears, cycloidal gearboxes are compact, low friction and feature virtually zero backlash. They also offer high reduction ratios, high load capacity and high efficiency. These features make them a viable option for a variety of applications.
Cycloid disks are driven by an eccentric input shaft. They are then driven by a stationary ring gear. The ring gear rotates the cycloidal disk at a higher rate. The input shaft rotates nine times to complete a full rotation. The ring gear is designed to correct the dynamic imbalance.
CZPT cycloidal gearheads are designed for precision and stable operation. These reducers are robust and can handle large translocations. They also offer high overload protection. They are suitable for shock wave therapy. CZPT gearheads are also well suited for applications with critical positioning accuracy. They also require low assembly and design costs. They are designed for long service life and low hysteresis loss.
CZPT cycloidal reducers are used in a variety of industrial applications, including CNC machining centers, robot positioners and manipulators. They offer a unique design that can handle high forces on the output axis, and are especially suitable for large translocations. These gearheads are highly efficient, reducing costs, and are available in a variety of sizes. They are ideal for applications that require millimetre accuracy.
High reduction ratios
Compared to other gearboxes, cycloidal gearboxes offer high reduction ratios and small backlash. They are also less expensive. Cycloid gearboxes can be used in a variety of industries. They are suitable for robotic applications. They also have high efficiency and load capacity.
A cycloidal gearbox works by rotating a cycloidal disc. This disc contains holes that are bigger than the pins on the output shaft. When the disc is rotated, the output pins move in the holes to generate a steady output shaft rotation. This type of gearbox does not require stacking stages.
Cycloid gearboxes are usually shorter than planetary gearboxes. Moreover, they are more robust and can transmit higher torques.
Cycloid gearboxes have an eccentric cam that drives the cycloidal disc. The cycloidal disc advances in 360deg/pivot/roller steps. It also rotates in an eccentric pattern. It meshes with the ring-gear housing. It also engages the internal teeth of the ring-gear housing.
The number of lobes on the cycloidal disc is not sufficient to generate a good transmission ratio. In fact, the number of lobes must be less than the number of pins surrounding the cycloidal disc.
The cycloidal disc is rotated by an eccentric cam that extends from the base shaft. The cam also spins inside the cycloidal disc. The eccentric motion of the cam helps the cycloidal disc rotate around the pins of the ring-gear housing.
Reducing amplitude of the vibration
Various approaches to reducing amplitude of the vibration in a cycloidal gearbox have been studied. These approaches are based on the kinematic analysis of gearbox.
A cycloidal gearbox is a gearbox that consists of bearings, gears, and an eccentric bearing that drives a cycloidal disc. This gearbox has a high reduction ratio, which is achieved by a series of output shaft pins that drive the output shaft as the disc rotates.
The test bench used in the studies has four sensors. Each sensor acquires signals with different signal processing techniques. In addition, there is a tachometer that acquires variations in rotational velocity at the input side.
The kinematic study of the robotic gearbox was performed to understand the frequency of vibrations and to determine whether the gearbox is faulty. It was found that the gearbox is in healthy operation when the amplitude of the x and y is low. However, when the amplitude is high, it is indicative of a malfunctioning element.
The frequency analysis of vibration signals is performed for both cyclostationary and noncyclostationary conditions. The frequencies that are selected are those that appear in both types of conditions.
Robust against shock loads
Compared to traditional gearboxes, cycloidal gearboxes have significant benefits when it comes to shock loads. These include high shock-load capacity, high efficiency, reduced cost, lower weight, lower friction, and better positioning accuracy.
Cycloid gears can be used to replace traditional planetary gears in applications where inertia is important, such as the transportation of heavy loads. They have a lighter design and can be manufactured to a more compact size, which helps reduce cost and installation expense. Cycloid gears are also able to provide transmission ratios of up to 300:1 in a small package.
Cycloid gears are also suitable for applications where a long service life is essential. Their radial clamping ring reduces inertia by up to 39%. Cycloid gears have a torsional stiffness that is five times higher than that of conventional planetary gears.
Cycloid gearboxes can provide significant improvements in concrete mixers. They are a highly efficient design, which allows for important innovations. They are also ideal for servo applications, machine tools, and medical technology. They feature user-friendly screw connections, effective corrosion protection, and effective handling.
Cycloid gears are especially useful for applications with critical positioning accuracy. For example, in the control of large parabolic antennas, high shock load capacity is required to maintain accuracy. Cycloid gears can withstand shock loads up to 500% of their rated torque.
Inertial effects
Various studies have been conducted to investigate the static problems of gears. However, there is still a need for a proper model to investigate the dynamic behaviour of a controlled system. For this, a mathematical model of a cycloidal gearbox has been developed. The presented model is a simple model that can be used as the basis for a more complex mechanical model.
The mathematical model is based on the cycloidal gearbox’s mechanical construction and has a nonlinear friction characteristic. The model is able to reproduce the current peaks and breaks at standstill. It also considers the stiction effect. However, it does not cover backlash or torsional stiffness.
This model is used to calculate the torque generating current and the inertia of the motor. These values are then compared with the real system measurement. The results show that the simulation results are very close to the real system measurement.
Several parameters are considered in the model to improve its dynamic behaviour. These parameters are calculated from the harmonic drive system analysis. These are torque-generating current, inertia, and the contact forces of the rotating parts.
The model has a high level of accuracy and can be used for motor control. It is also able to reproduce the dynamic behaviour of a controlled system.

Developing a Mathematical Model of a Cyclone Gearbox
Compared to planetary gearboxes, cycloidal gearboxes are often seen as the ideal choice for a wide range of applications. They feature compact designs that are often low friction and high reduction ratios.
Low friction
Developing a mathematical model of a cycloidal gearbox was a challenge. The model was able to show the effects of a variety of geometric parameters on contact stresses. It was able to model stiction in all quadrants. It was able to show a clear correlation between the results from simulation and real-world measurements.
The model is based on a new approach that enables modeling stiction in all quadrants of a gearbox. It is also able to display non-zero current at standstill. Combined with a good simulation algorithm, the model can be used to improve the dynamic behaviour of a controlled system.
A cycloidal gearbox is a compact actuator used for industrial automation. This type of gearbox provides high gear ratios, low wear, and good torsional stiffness. In addition, it has good shock load capacity.
The model is based on cycloidal discs that engage with pins on a stationary ring gear. The resulting friction function occurs when the rotor begins to rotate. It also occurs when the rotor reverses its rotation. The model has two curves, one for motor and one for generator mode.
The trochoidal profile on the cycloidal disc’s periphery is required for proper mating of the rotating parts. In addition, the profile should be defined accurately. This will allow an even distribution of contact forces.
The model was used to compare the relative performance of a cycloidal gearbox with that of an involute gearbox. This comparison indicates that the cycloidal gearbox can withstand more load than an involute gearbox. It is also able to last longer. It is also able to produce high gear ratios in a small space.
The model used is able to capture the exact geometry of the parts. It can also allow a better analysis of stresses.
Compact
Unlike helical gearing, compact cycloidal gearboxes can provide higher reduction ratios. They are more compact and less weighty. In addition, they provide better positioning accuracy.
Cycloid drives provide high torque and load capacity. They are also very efficient and robust. They are ideal for applications with heavy loads or shock loads. They also feature low backlash and high torsional stiffness. Cycloid gearboxes are available in a variety of designs.
Cycloid discs are mounted on an eccentric input shaft, which drives them around a stationary ring gear. The ring gear consists of many pins, and the cycloidal disc moves one lobe for every rotation of the input shaft. The output shaft contains roller pins, which rotate around holes in the cycloidal disc.
Cycloid drives are ideally suited to heavy loads and shock loads. They have high torsional stiffness and high reduction ratios, making them very efficient. Cycloid gearboxes have low backlash and high torque and are very compact.
Cycloid gearboxes are used for a wide variety of applications, including marine propulsion systems, CNC machining centers, medical technology, and manipulation robots. They are especially useful in applications with critical positioning accuracy, such as surgical positioning systems. Cycloid gearboxes feature extremely low hysteresis loss and low backlash over extended periods of use.
Cycloid discs are usually designed with a reduced cycloid diameter to minimize unbalance forces at high speeds. Cycloid drives also feature minimal backlash, a high reduction ratio, and excellent positioning accuracy. Cycloid gearboxes also have a long service life, compared to other gear drives. Cycloid drives are highly robust, and offer higher reduction ratios than helical gear drives.
Cycloid gearboxes have a low cost and are easy to print. CZPT gearboxes are available in a wide range of sizes and can produce high torque on the output axis.
High reduction ratio
Among the types of gearboxes available, a high reduction ratio cycloidal gearbox is a popular choice in the automation field. This gearbox is used in applications requiring precise output and high efficiency.
Cycloid gears can provide high torque and transmit it well. They have low friction and a small backlash. They are widely used in robotic joints. However, they require special tools to manufacture. Some have even been 3D printed.
A cycloidal gearbox is typically a three-stage structure that includes an input hub, an output hub, and two cycloidal gears that rotate around each other. The input hub mounts movable pins and rollers, while the output hub mounts a stationary ring gear.
The input shaft is driven by an eccentric bearing. The disc is then pushed against the ring gear, which causes it to rotate around the bearing. As the disc rotates, the pins on the ring gear drive the pins on the output shaft.
The input shaft rotates a maximum of nine revolutions, while the output shaft rotates three revolutions. This means that the input shaft has to rotate over eleven million times before the output shaft is able to rotate. The output shaft also rotates in the opposite direction of the input shaft.
In a two-stage differential cycloidal speed reducer, the input shaft uses a crank shaft design. The crank shaft connects the first and second cycloidal gears and actuates them simultaneously.
The first stage is a cycloidal disc, which is a gear tooth profile. It has n=7 lobes on its circumference. Each lobe moves around a reference pitch circle of pins. The disc then advances in 360deg steps.
The second stage is a cycloidal disc, also known as a “grinder gear”. The teeth on the outer gear are fewer than the teeth on the inner gear. This allows the gear to be geardown based on the number of teeth.
Kinematics
Various scholars have studied the kinematics of cycloidal gearbox. They have developed various approaches to modify the tooth profile of cycloidal gears. Some of these approaches involve changing the shape of the cycloidal disc, and changing the grinding wheel center position.
This paper describes a new approach to cycloid gear profile modification. It is based on a mathematical model and incorporates several important parameters such as pressure angle, backlash, and root clearance. The study offers a new way for modification design of cycloid gears in precision reducers for robots.
The pressure angle of a tooth profile is an intersegment angle between the normal direction and the velocity direction at a meshing point. The pressure angle distribution is important for determining force transmission performance of gear teeth in meshing. The distribution trend can be obtained by calculating the equation (5).
The mathematical model for modification of the tooth profile can be obtained by establishing the relationship between the pressure angle distribution and the modification function. The dependent variable is the modification DL and the independent variable is the pressure angle a.
The position of the reference point A is a major consideration in the modification design. It ensures the force transmission performance of the meshing segment is optimal. It is determined by the smallest profile pressure angle. The position is also dependent on the type of gear that is being modified. It is also influenced by the tooth backlash.
The mathematical model governing the pressure angle distribution is developed with DL=f(a). It is a piecewise function that determines the pressure angle distribution of a tooth profile. It can also be expressed as DL=ph.
The pressure angle of a tooth is also an angle between the common normal direction at the meshing point and the rotation velocity direction of the cycloid gear.
Planetary gearboxes vs cycloidal gearboxes
Generally, there are two types of gearboxes that are used for motion control applications: cycloidal gearbox and planetary gearbox. Cycloid gearboxes are used for high-frequency motions, while planetary gearboxes are suitable for low-speed applications. Both are highly accurate and precise gearboxes that are capable of handling heavy loads at high cycle rates. But they have different advantages and disadvantages. So, engineers need to determine which type of gearbox is best suited for their application.
Cycloid gearboxes are commonly used in industrial automation. They provide excellent performance with ratios as low as 10:1. They offer a more compact design, higher torque density and greater overload protection. They also require less space and are less expensive than planetary gearboxes.
On the other hand, planetary gearboxes are lightweight and offer a higher torque density. They are also capable of handling higher ratios. They have a longer life span and are more precise and durable. They can be found in a variety of styles, including square-framed, round-framed and double-frame designs. They offer a wide range of torque and speed capabilities and are used for numerous applications.
Cycloid gearboxes can be manufactured with different types of cycloidal cams, including single or compound cycloidal cams. Cycloid cams are cylindrical elements that have cam followers that rotate in an eccentric fashion. The cam followers act like teeth on the internal gear. Cycloid cams are a simple concept, but they have numerous advantages. They have a low backlash over extended periods of time, allowing for more accurate positioning. They also have internal compressive stresses and an overlap factor between the rolling elements.
Planetary gearboxes are characterized by three basic force-transmitting elements: ring gear, sun gear, and planet gear. They are generally two-stage gearboxes. The sun gear is attached to the input shaft, which in turn is attached to the servomotor. The ring gear turns the sun gear and the planet gear turns the output shaft.

The model is based on a new approach that enables modeling stiction in all quadrants of a gearbox. It is also able to display non-zero current at standstill. Combined with a good simulation algorithm, the model can be used to improve the dynamic behaviour of a controlled system.
A cycloidal gearbox is a compact actuator used for industrial automation. This type of gearbox provides high gear ratios, low wear, and good torsional stiffness. In addition, it has good shock load capacity.
The model is based on cycloidal discs that engage with pins on a stationary ring gear. The resulting friction function occurs when the rotor begins to rotate. It also occurs when the rotor reverses its rotation. The model has two curves, one for motor and one for generator mode.
The trochoidal profile on the cycloidal disc’s periphery is required for proper mating of the rotating parts. In addition, the profile should be defined accurately. This will allow an even distribution of contact forces.
The model was used to compare the relative performance of a cycloidal gearbox with that of an involute gearbox. This comparison indicates that the cycloidal gearbox can withstand more load than an involute gearbox. It is also able to last longer. It is also able to produce high gear ratios in a small space.
The model used is able to capture the exact geometry of the parts. It can also allow a better analysis of stresses.
Compact
Unlike helical gearing, compact cycloidal gearboxes can provide higher reduction ratios. They are more compact and less weighty. In addition, they provide better positioning accuracy.
Cycloid drives provide high torque and load capacity. They are also very efficient and robust. They are ideal for applications with heavy loads or shock loads. They also feature low backlash and high torsional stiffness. Cycloid gearboxes are available in a variety of designs.
Cycloid discs are mounted on an eccentric input shaft, which drives them around a stationary ring gear. The ring gear consists of many pins, and the cycloidal disc moves one lobe for every rotation of the input shaft. The output shaft contains roller pins, which rotate around holes in the cycloidal disc.
Cycloid drives are ideally suited to heavy loads and shock loads. They have high torsional stiffness and high reduction ratios, making them very efficient. Cycloid gearboxes have low backlash and high torque and are very compact.
Cycloid gearboxes are used for a wide variety of applications, including marine propulsion systems, CNC machining centers, medical technology, and manipulation robots. They are especially useful in applications with critical positioning accuracy, such as surgical positioning systems. Cycloid gearboxes feature extremely low hysteresis loss and low backlash over extended periods of use.
Cycloid discs are usually designed with a reduced cycloid diameter to minimize unbalance forces at high speeds. Cycloid drives also feature minimal backlash, a high reduction ratio, and excellent positioning accuracy. Cycloid gearboxes also have a long service life, compared to other gear drives. Cycloid drives are highly robust, and offer higher reduction ratios than helical gear drives.
Cycloid gearboxes have a low cost and are easy to print. CZPT gearboxes are available in a wide range of sizes and can produce high torque on the output axis.
High reduction ratio
Among the types of gearboxes available, a high reduction ratio cycloidal gearbox is a popular choice in the automation field. This gearbox is used in applications requiring precise output and high efficiency.
Cycloid gears can provide high torque and transmit it well. They have low friction and a small backlash. They are widely used in robotic joints. However, they require special tools to manufacture. Some have even been 3D printed.
A cycloidal gearbox is typically a three-stage structure that includes an input hub, an output hub, and two cycloidal gears that rotate around each other. The input hub mounts movable pins and rollers, while the output hub mounts a stationary ring gear.
The input shaft is driven by an eccentric bearing. The disc is then pushed against the ring gear, which causes it to rotate around the bearing. As the disc rotates, the pins on the ring gear drive the pins on the output shaft.
The input shaft rotates a maximum of nine revolutions, while the output shaft rotates three revolutions. This means that the input shaft has to rotate over eleven million times before the output shaft is able to rotate. The output shaft also rotates in the opposite direction of the input shaft.
In a two-stage differential cycloidal speed reducer, the input shaft uses a crank shaft design. The crank shaft connects the first and second cycloidal gears and actuates them simultaneously.
The first stage is a cycloidal disc, which is a gear tooth profile. It has n=7 lobes on its circumference. Each lobe moves around a reference pitch circle of pins. The disc then advances in 360deg steps.
The second stage is a cycloidal disc, also known as a “grinder gear”. The teeth on the outer gear are fewer than the teeth on the inner gear. This allows the gear to be geardown based on the number of teeth.
Kinematics
Various scholars have studied the kinematics of cycloidal gearbox. They have developed various approaches to modify the tooth profile of cycloidal gears. Some of these approaches involve changing the shape of the cycloidal disc, and changing the grinding wheel center position.
This paper describes a new approach to cycloid gear profile modification. It is based on a mathematical model and incorporates several important parameters such as pressure angle, backlash, and root clearance. The study offers a new way for modification design of cycloid gears in precision reducers for robots.
The pressure angle of a tooth profile is an intersegment angle between the normal direction and the velocity direction at a meshing point. The pressure angle distribution is important for determining force transmission performance of gear teeth in meshing. The distribution trend can be obtained by calculating the equation (5).
The mathematical model for modification of the tooth profile can be obtained by establishing the relationship between the pressure angle distribution and the modification function. The dependent variable is the modification DL and the independent variable is the pressure angle a.
The position of the reference point A is a major consideration in the modification design. It ensures the force transmission performance of the meshing segment is optimal. It is determined by the smallest profile pressure angle. The position is also dependent on the type of gear that is being modified. It is also influenced by the tooth backlash.
The mathematical model governing the pressure angle distribution is developed with DL=f(a). It is a piecewise function that determines the pressure angle distribution of a tooth profile. It can also be expressed as DL=ph.
The pressure angle of a tooth is also an angle between the common normal direction at the meshing point and the rotation velocity direction of the cycloid gear.
Planetary gearboxes vs cycloidal gearboxes
Generally, there are two types of gearboxes that are used for motion control applications: cycloidal gearbox and planetary gearbox. Cycloid gearboxes are used for high-frequency motions, while planetary gearboxes are suitable for low-speed applications. Both are highly accurate and precise gearboxes that are capable of handling heavy loads at high cycle rates. But they have different advantages and disadvantages. So, engineers need to determine which type of gearbox is best suited for their application.
Cycloid gearboxes are commonly used in industrial automation. They provide excellent performance with ratios as low as 10:1. They offer a more compact design, higher torque density and greater overload protection. They also require less space and are less expensive than planetary gearboxes.
On the other hand, planetary gearboxes are lightweight and offer a higher torque density. They are also capable of handling higher ratios. They have a longer life span and are more precise and durable. They can be found in a variety of styles, including square-framed, round-framed and double-frame designs. They offer a wide range of torque and speed capabilities and are used for numerous applications.
Cycloid gearboxes can be manufactured with different types of cycloidal cams, including single or compound cycloidal cams. Cycloid cams are cylindrical elements that have cam followers that rotate in an eccentric fashion. The cam followers act like teeth on the internal gear. Cycloid cams are a simple concept, but they have numerous advantages. They have a low backlash over extended periods of time, allowing for more accurate positioning. They also have internal compressive stresses and an overlap factor between the rolling elements.
Planetary gearboxes are characterized by three basic force-transmitting elements: ring gear, sun gear, and planet gear. They are generally two-stage gearboxes. The sun gear is attached to the input shaft, which in turn is attached to the servomotor. The ring gear turns the sun gear and the planet gear turns the output shaft.

Principle of Cycloidal Gearing
Cycloidal gearing is a mechanism that utilizes the unique shape of cycloidal discs to achieve motion transmission. The principle involves the interaction between two main components: the input disc and the output disc.
The input disc has lobes with pins, while the output disc has lobes with matching holes. The lobes on both discs are not perfectly circular but are shaped in a cycloidal profile. As the input disc rotates, the pins on its lobes engage with the holes in the output disc’s lobes.
As the input disc rotates, the pins move along the cycloidal paths, causing the output disc to rotate. The interaction between the pins and the holes results in smooth and continuous motion transfer. The unique shape of the cycloidal profile ensures that there is always at least one point of contact between the pins and the holes, allowing for efficient torque transmission and reduced wear.
Cycloidal gearing provides advantages such as high torque capacity, compact size, and precision motion. However, due to the complex shape of the components and the continuous engagement, manufacturing and assembly of cycloidal gearboxes can be intricate.
