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 .

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:

  1. 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.
  2. 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.
  3. 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.

The Advantages of Using a Cyclone Gearbox

Using a cycloidal gearbox to drive an input shaft is a very effective way to reduce the speed of a machine. It does this by reducing the speed of the input shaft by a predetermined ratio. It is capable of very high ratios in relatively small sizes.

Transmission ratio

Whether you’re building a marine propulsion system or a pump for the oil and gas industry, there are certain advantages to using cycloidal gearboxes. Compared to other gearbox types, they’re shorter and have better torque density. These gearboxes also offer the best weight and positioning accuracy.
The basic design of a cycloidal gearbox is similar to that of a planetary gearbox. The main difference is in the profile of the gear teeth.
Cycloid gears have less tooth flank wear and lower Hertzian contact stress. They also have lower friction and torsional stiffness. These advantages make them ideal for applications that involve heavy loads or high-speed drives. They’re also good for high gear ratios.
In a cycloidal gearbox, the input shaft drives an eccentric bearing, while the output shaft drives the cycloidal disc. The cycloidal disc rotates around a fixed ring, and the pins of the ring gear engage the holes in the disc. The pins then drive the output shaft as the disc rotates.
Cycloid gears are ideal for applications that require high gear ratios and low friction. They’re also good for applications that require high torsional stiffness and shock load resistance. They’re also suitable for applications that require a compact design and low backlash.
The transmission ratio of a cycloidal gearbox is determined by the number of lobes on the cycloidal disc. The n=n design of the cycloidal disc moves one lobe per revolution of the input shaft.
Cycloid gears can be manufactured to reduce the gear ratio from 30:1 to 300:1. These gears are suitable for high-end applications, especially in the automation industry. They also offer the best positioning accuracy and backlash. However, they require special manufacturing processes and require non-standard characteristics.

Compressive force

Compared with conventional gearboxes, the cycloidal gearbox has a unique set of kinematics. It has an eccentric bearing in a rotating frame, which drives the cycloidal disc. It is characterized by low backlash and torsional stiffness, which enables geared motion.
In this study, the effects of design parameters were investigated to develop the optimal design of a cycloidal reducer. Three main rolling nodes were studied: a cycloidal disc, an outer race and the input shaft. These were used to analyze the motion related dynamic forces, which can be used to calculate stresses and strains. The gear mesh frequency was calculated using a formula, which incorporated a correction factor for the rotating frame of the outer race.
A three-dimensional finite element analysis (FEA) study was conducted to evaluate the cycloidal disc. The effects of the size of the holes on the disc’s induced stresses were investigated. The study also looked at the torque ripple of a cycloidal drive.
The authors of this study also explored backlash distribution in the output mechanism, which took into account the machining deviations and structure and geometry of the output mechanism. The study also looked at the relative efficiency of a cycloidal reducer, which was based on a single disc cycloidal reducer with a one-tooth difference.
The authors of this study were able to deduce the contact stress of the cycloidal disc, which is calculated using the material-based contact stiffness. This can be used to determine accurate contact stresses in a cycloidal gearbox.
It is important to know the ratios needed for calculation of the bearing rate. This can be calculated using the formula f = k (S x R) where S is the volume of the element, R is the mass, k is the contact stiffness and f is the force vector.helical gearbox

Rotational direction

Unlike the conventional ring gear which has a single axis of rotation, cycloidal gearbox has three rotational axes which are parallel and are located in a single plane. A cycloidal gearbox has excellent torsional stiffness and shock load capacity. It also ensures constant angular velocity, and is used in high-speed gearbox applications.
A cycloidal gearbox consists of an input shaft, a drive member and a cycloidal disc. The disc rotates in one direction, while the input shaft rotates in the opposite direction. The input shaft eccentrically mounts to the drive member. The cycloidal disc meshes with the ring-gear housing, and the rotational motion of the cycloidal disc is transferred to the output shaft.
To calculate the rotational direction of a cycloidal gearbox, the cycloid must have the correct angular orientation and the centerline of the cycloid should be aligned with the center of the output hole. The cycloid’s shortest length should be equal to the radius of the pin circle. The cycloid’s largest radius should be the size of the bearing’s exterior diameter.
A single-stage gear will not have much space to work with, so you’ll need a multistage gear to maximize space. This is also the reason that cycloid gears are usually designed with a shortened cycloid.
To calculate the most efficient tooth profile for a cycloidal gear, a new method was devised. This method uses a mathematical model that uses the cycloid’s rotational direction and a few other geometric parameters. Using a piecewise function related to the distribution of pressure angle, the cycloid’s most efficient profile is determined. It is then superimposed on the theoretical profile. The new method is much more flexible than the conventional method, and can adapt to changing trends of the cycloidal profile.

Design

Several designs of cycloidal gearboxes have been developed. These gearboxes have a large reduction ratio in one stage. They are mainly used for heavy machines. They provide good torsional stiffness and shock load capacity. However, they also have vibrations at high RPM. Several studies have been conducted to find a solution to this problem.
A cycloidal gearbox is designed by calculating the reduction ratio of a mechanism. This ratio is obtained by the size of the input speed. This is then multiplied by the reduction ratio of the gear profile.
The most important factor in the design of a cycloidal gearbox is the load distribution along the width of the gear. Using this as a design criterion, the amplitude of vibration can be reduced. This will ensure that the gearbox is working properly. In order to generate proper mating conditions, the trochoidal profile on the cycloidal disc periphery must be defined accurately.
One of the most common forms of cycloidal gears is circular arc toothing. This is the most common type of toothing used today.
Another form of gear is the hypocycloid. This form requires the rolling circle diameter to be equal to half the base circle diameter. Another special case is the point tooth form. This form is also called clock toothing.
In order to make this gear profile work, the initial point of contact must remain fixed to the edge of the rolling disk. This will generate the hypocycloid curve. The curve is traced from this initial point.
To investigate this gear profile, the authors used a 3D finite element analysis. They used the mathematical model of gear manufacturing that included kinematics parameters, output moment calculations, and machining steps. The resulting design eliminated backlash.helical gearbox

Sizing and selection

Choosing a gearbox can be a complex task. There are many factors that need to be taken into account. You need to determine the type of application, the required speed, the load, and the ratio of the gearbox. By gaining this information, you can find a solution that works best for you.
The first thing you need to do is find the proper size. There are several sizing programs available to help you determine the best gearbox for your application. You can start by drawing a cycloidal gear to help you create the part.
During sizing, it is important to consider the environment. Shock loads, environmental conditions, and ambient temperatures can increase wear on the gear teeth. The temperature also has a significant impact on lubrication viscosities and seal materials.
You also need to consider the input and output speed. This is because the input speed will change your gearbox ratio calculations. If you exceed the input speed, you can damage the seals and cause premature wear on the shaft bearings.
Another important aspect of sizing is the service factor. This factor determines the amount of torque the gearbox can handle. The service factor can be as low as 1.4, which is sufficient for most industrial applications. However, high shock loads and impact loads will require higher service factors. Failure to account for these factors can lead to broken shafts and damaged bearings.
The output style is also important. You need to determine if you want a keyless or keyed hollow bore, as well as if you need an output flange. If you choose a keyless hollow bore, you will need to select a seal material that can withstand the higher temperatures.

Efficiency of Cycloidal Gearboxes in Power Transmission

Cycloidal gearboxes offer relatively high power transmission efficiency compared to other types of gearboxes. The efficiency of a cycloidal gearbox depends on various factors, including the design, quality of components, lubrication, and load conditions.

Typically, the power transmission efficiency of a cycloidal gearbox ranges from 85% to 95%. However, this can vary based on several factors:

  • Number of Reduction Stages: Multi-stage cycloidal gearboxes may experience slightly lower efficiency due to multiple gear meshing interactions.
  • Quality and Design: Well-designed and precision-manufactured cycloidal gearboxes tend to exhibit higher efficiency.
  • Lubrication: Proper lubrication is crucial for reducing friction and enhancing efficiency. Insufficient or deteriorated lubrication can lead to efficiency losses.
  • Load Conditions: Higher loads and torque levels can lead to higher friction and lower efficiency. Properly matching the gearbox to the application is essential.

Despite minor efficiency losses compared to some other gearbox types, the benefits of compactness, high torque density, and precise motion control often outweigh the efficiency considerations in many applications.

  • 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.

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.helical gearbox

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.

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.helical gearbox

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.

Efficiency of Cycloidal Gearboxes in Power Transmission

Cycloidal gearboxes offer relatively high power transmission efficiency compared to other types of gearboxes. The efficiency of a cycloidal gearbox depends on various factors, including the design, quality of components, lubrication, and load conditions.

Typically, the power transmission efficiency of a cycloidal gearbox ranges from 85% to 95%. However, this can vary based on several factors:

  • Number of Reduction Stages: Multi-stage cycloidal gearboxes may experience slightly lower efficiency due to multiple gear meshing interactions.
  • Quality and Design: Well-designed and precision-manufactured cycloidal gearboxes tend to exhibit higher efficiency.
  • Lubrication: Proper lubrication is crucial for reducing friction and enhancing efficiency. Insufficient or deteriorated lubrication can lead to efficiency losses.
  • Load Conditions: Higher loads and torque levels can lead to higher friction and lower efficiency. Properly matching the gearbox to the application is essential.

Despite minor efficiency losses compared to some other gearbox types, the benefits of compactness, high torque density, and precise motion control often outweigh the efficiency considerations in many applications.

Noise and Vibration Considerations in Cycloidal Gearboxes

Cycloidal gearboxes are generally known for their smooth and quiet operation. However, like any mechanical system, they can still exhibit some level of noise and vibration. Here are the key factors to consider:

  • Gear Design: The unique rolling contact design of cycloidal gears contributes to their relatively low noise levels. The teeth engagement is gradual and continuous, reducing impact forces and noise.
  • Lubrication: Proper lubrication is essential to minimize friction and noise. Using high-quality lubricants and maintaining proper lubrication levels can help reduce noise and vibration in cycloidal gearboxes.
  • Precision Manufacturing: Precise manufacturing processes and tight tolerances can help minimize irregularities in gear meshing, which can contribute to noise and vibration.
  • Load Distribution: Proper load distribution among multiple lobes in the cycloidal mechanism can help prevent localized stress concentrations that could lead to vibrations and noise.
  • Bearing Quality: High-quality bearings can contribute to smooth operation and reduce vibrations that could be transmitted to the gearbox housing.
  • Mounting and Installation: Proper mounting and alignment of the gearbox are important to ensure that it operates smoothly and without excessive vibrations.

While cycloidal gearboxes are designed to minimize noise and vibration, it’s important to consider the specific application, environmental conditions, and operating parameters. Regular maintenance, proper lubrication, and selecting the appropriate gearbox size and type can all contribute to reducing noise and vibration levels in cycloidal gearboxes.

cycloidal gearbox

Distinguishing Features of Cycloidal Gearboxes

Cycloidal gearboxes, also known as cycloidal drives or cycloidal reducers, possess distinct characteristics that set them apart from other types of gearboxes:

  • Principle of Operation: Cycloidal gearboxes utilize the principle of cycloidal motion, where input shaft movement is transformed into eccentric motion of the cycloidal disc. This unique mechanism results in smooth and consistent output motion.
  • Compactness: Cycloidal gearboxes are renowned for their compact size and high torque density. The concentric design of the components contributes to their ability to transmit substantial torque in a relatively small package.
  • Tooth Profile: Cycloidal gearboxes employ specialized cycloidal teeth, which involve both pinwheel and roller gears. This distinctive tooth profile contributes to the characteristic smooth and vibration-free operation.
  • Reduction Mechanism: They often employ multi-lobed cam gears that interact with the pins on the cycloidal disc, resulting in multiple gear engagements per revolution and improved load distribution.
  • Motion Control: Cycloidal gearboxes offer high positional accuracy and motion control due to the eccentric motion of the disc, making them suitable for robotics, automation, and precision applications.
  • Backlash: They typically exhibit low backlash due to the nature of the engagement mechanism, making them advantageous for applications requiring precise and reversible motion.
  • Applications: Cycloidal gearboxes are commonly used in various industries, including robotics, packaging, material handling, printing, and more, where their compactness, precision, and efficiency are valued.

These distinguishing features contribute to the unique capabilities and benefits of cycloidal gearboxes in specific applications.
