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.

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.

helical gearbox

The Cyclonoidal Gearbox

Basically, the cycloidal gearbox is a gearbox that uses a cycloidal motion to perform its rotational movement. It is a very simple and efficient design that can be used in a variety of applications. A cycloidal gearbox is often used in applications that require the movement of heavy loads. It has several advantages over the planetary gearbox, including its ability to be able to handle higher loads and higher speeds.

Dynamic and inertial effects of a cycloidal gearbox

Several studies have been conducted on the dynamic and inertial effects of a cycloidal gearbox. Some of them focus on operating principles, while others focus on the mathematical model of the gearbox. This paper examines the mathematical model of a cycloidal gearbox, and compares its performance with the real-world measurements. It is important to have a proper mathematical model to design and control a cycloidal gearbox. A cycloidal gearbox is a two-stage gearbox with a cycloid disc and a ring gear that revolves around its own axis.
The mathematical model is made up of more than 1.6 million elements. Each gear pair is represented by a reduced model with 500 eigenmodes. The eigenfrequency for the spur gear is 70 kHz. The modally reduced model is a good fit for the cycloidal gearbox.
The mathematical model is validated using ABAQUS software. A cycloid disc was discretized to produce a very fine model. It requires 400 element points per tooth. It was also verified using static FEA. This model was then used to model the stiction of the gears in all quadrants. This is a new approach to modelling stiction in a cycloidal gearbox. It has been shown to produce results comparable to those of the EMBS model. The results are also matched by the elastic multibody simulation model. This is a good fit for the contact forces and magnitude of the cycloid gear disc. It was also found that the transmission accuracy between the cycloid gear disc and the ring gear is about 98.5%. However, this value is lower than the transmission accuracy of the ring gear pair. The transmission error of the corrected model is about 0.3%. The transmission accuracy is less because of the lower amount of elastic deformation on the tooth flanks.
It is important to note that the most accurate contact forces for each tooth of a cycloid gearbox are not smooth. The contact force on a single tooth starts with a linear rise and then ends with a sharp drop. It is not as smooth as the contact force on a point contact, which is why it has been compared to the contact force on an ellipse contact. However, the contact on an ellipse contact is still relatively small, and the EMBS model is not able to capture this.
The FE model for the cycloid disc is about 1.6 million elements. The most important part of the FE model is the discretization of the cycloid disc. It is very important to do the discretization of the cycloid gear disc very carefully because of the high degree of vibration that it experiences. The cycloid disc has to be discretized finely so that the results are comparable to those of a static FEA. It has to be the most accurate model possible in order to be able to accurately simulate the contact forces between the cycloid disc and the ring gear.helical gearbox

Kinematics of a cycloidal drive

Using an arbitrary coordinate system, we can observe the motion of components in a cycloidal gearbox. We observe that the cycloidal disc rotates around fixed pins in a circle, while the follower shaft rotates around the eccentric cam. In addition, we see that the input shaft is mounted eccentrically to the rolling-element bearing.
We also observe that the cycloidal disc rotates independently around the eccentric bearing, while the follower shaft rotates around an axis of symmetry. We can conclude that the cycloidal disc plays a pivotal role in the kinematics of a cycloidal gearbox.
To calculate the efficiency of the cycloidal reducer, we use a model that is based on the non-linear stiffness of the contacts. In this model, the non-linearity of the contact is governed by the non-linearity of the force and the deformation in the contact. We have shown that the efficiency of the cycloidal reducer increases as the load increases. In addition, the efficiency is dependent on the sliding velocity and the deformations of the normal load. These factors are considered as the key variables to determine the efficiency of the cycloidal drive.
We also consider the efficiency of the cycloidal reducer with the input torque and the input speed. We can calculate the efficiency by dividing the net torque in the ring gear by the output torque. The efficiency can be adjusted to suit different operating conditions. The efficiency of the cycloidal drive is increased as the load increases.
The cycloidal gearbox is a multi-stage gearbox with a small shaft oin and a big shaft. It has 19 teeth and brass washers. The outer discs move in opposition to the middle disc, and are offset by 180 deg. The middle disc is twice as massive as the outer disc. The cycloidal disc has nine lobes that move by one lobe per drive shaft revolution. The number of pins in the disc should be smaller than the number of pins in the surrounding pins.
The input shaft drives an eccentric bearing that is able to transmit the power to the output shaft. In addition, the input shaft applies forces to the cycloidal disk through the intermediate bearing. The cycloidal disk then advances in 360 deg/pivot/roller steps. The output shaft pins then move around in the holes to make the output shaft rotate continuously. The input shaft applies a sinusoidal motion to maintain the constant speed of the base shaft. This sine wave causes small adjustments to the follower shaft. The forces applied to the internal sleeves are a part of the equilibrium mechanism.
In addition, we can observe that the cycloidal drive is capable of transmitting a greater torque than the planetary gear. This is due to the cycloidal gear’s larger axial length and the ring gear’s smaller hole diameter. It is also possible to achieve a positive fit between the fixed ring and the disc, which is achieved by toothing between the fixed ring and the disc. The cycloidal disk is usually designed with a short cycloid to minimize unbalance forces at high speeds.helical gearbox

Comparison with planetary gearboxes

Compared to planetary gearboxes, the cycloidal gearbox has some advantages. These advantages include: low backlash, better overload capacity, a compact design, and the ability to perform in a wide range of applications. The cycloidal gearbox has become popular in the multi-axis robotics market. The gearbox is also increasingly used in first joints and positioners.
A cycloidal gearbox is a gearbox that consists of four basic components: a cycloid disk, an output flange, a ring gear, and a fixed ring. The cycloid disk is driven by an eccentric shaft, which advances in a 360deg/pivot/roller step. The output flange is a fixed pin disc that transmits the power to the output shaft. The ring gear is a fixed ring, and the input shaft is connected to a servomotor.
The cycloidal gearbox is designed to control inertia in highly dynamic situations. These gearboxes are generally used in robotics and positioners, where they are used to position heavy loads. They are also commonly used in a wide range of industrial applications. They have higher torque density and a low backlash, making them ideal for heavy loads.
The output flange is also designed to handle a torque of up to 500 Nm. Its rotational speed is lower than the planet gearbox, but its output torque is much higher. It is designed to be a high-performance gearbox, and it can be used in applications that need high ratios and a high level of torque density. The cycloid gearbox is also less expensive and has less backlash. However, the cycloidal gearbox has disadvantages that should be considered when designing a gearbox. The main problem is vibrations.
Compared to planetary gearboxes, cycloidal gearboxes have a smaller overall size and are less expensive. In addition, the cycloid gearbox has a large reduction ratio in one stage. In general, cycloidal gearboxes have single or two stages, with the third stage being less common. However, the cycloid gearbox is not the only type of gearbox that has this type of configuration. It is also common to find a planetary gearbox with a single stage.
There are several different types of cycloidal gearboxes, and they are often referred to as cycloidal speed reducers. These gearboxes are designed for any industry that uses servos. They are shorter than planetary gearboxes, and they are larger in diameter for the same torque. Some of them are also available with a ratio lower than 30:1.
The cycloid gearbox can be a good choice for applications where there are high rotational speeds and high torque requirements. These gearboxes are also more compact than planetary gearboxes, and are suitable for high-torque applications. In addition, they are more robust and can handle shock loads. They also have low backlash, and a higher level of accuracy and positioning accuracy. They are also used in a wide range of applications, including industrial robotics.

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.

Maintenance Requirements for Cycloidal Gearboxes

Maintaining cycloidal gearboxes is essential to ensure their optimal performance and longevity. Here are some maintenance practices to consider:

  • Lubrication: Regular lubrication is crucial to prevent wear and friction between moving parts. Use high-quality lubricants recommended by the gearbox manufacturer.
  • Inspections: Regularly inspect the gearbox for signs of wear, damage, or oil leakage. Address any issues promptly to prevent further damage.
  • Cleaning: Keep the gearbox clean and free from debris that could interfere with its operation. Cleanliness helps prevent contamination and wear.
  • Torque Checks: Periodically check the tightness of fasteners and bolts to ensure they are properly secured. Loose fasteners can lead to misalignment and reduced performance.
  • Seal Maintenance: Check and maintain seals to prevent oil leakage. Damaged seals should be replaced promptly to avoid lubricant loss.
  • Temperature Monitoring: Monitor the operating temperature of the gearbox to ensure it remains within the recommended range. Excessive heat can lead to premature wear.

Disadvantages of Using a Cycloidal Gearbox

While cycloidal gearboxes offer various advantages, they also come with some disadvantages that should be considered:

  • Lower Efficiency at High Speeds: Cycloidal gearboxes can experience a decrease in efficiency at high speeds due to increased friction and rolling resistance.
  • Complex Design: The internal arrangement of pins, lobes, and bearings can result in a relatively complex design, which may lead to higher manufacturing costs and maintenance challenges.
  • Limited Gear Ratio Range: Cycloidal gearboxes might have limitations in terms of achieving very high gear ratios, which can impact their suitability for certain applications.
  • Cost: The specialized design and precision manufacturing involved in producing cycloidal gearboxes can lead to higher upfront costs compared to other gearbox types.
  • Noise Generation: While generally quieter than some other types of gearboxes, cycloidal gearboxes can still produce noise during operation, which might need to be addressed in noise-sensitive applications.
  • Availability: Cycloidal gearboxes might not be as widely available as other gearbox types, potentially leading to longer lead times for procurement and replacement parts.
  • Limited Backlash Adjustability: While cycloidal gearboxes have minimal backlash, adjusting or fine-tuning the backlash might be more challenging compared to other gearbox types.

Despite these disadvantages, cycloidal gearboxes remain a valuable choice for specific applications where their unique advantages outweigh the drawbacks.

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.

cycloidal gearbox

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.

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.

The Basics of Designing a Cyclone Gearbox

Compared to conventional gearboxes, the cycloidal gearbox offers a number of advantages including a higher ratio of transmission, robustness against shock loads, and greater positioning accuracy. However, designing a cycloidal gearbox can be complicated. This article will discuss some of the basic design principles. In addition, it will cover topics such as size, position accuracy, and transmission ratios.

Basic design principles

Unlike a conventional ring gear, a cycloidal gearbox uses a cycloidal disc to provide torque multiplication. The output direction of the cycloidal gear disc is opposite to the rotation of the input shaft. This allows for more compact gear construction. It also allows for increased load capacity.
Cycloid drive kinematics can appear complex, but they are actually quite simple. Instead of rotating around the center of gravity like conventional gears, the cycloidal disc rotates around fixed pins. This provides a higher reduction ratio.
To reduce vibrations and noise, multiple cycloidal discs are used. This allows for uniform distribution of forces on the carrier pin devices. This also provides a better rotational balance. In addition, multiple cycloidal discs reduce the axial moment of the carrier pin devices.
The cycloidal gear disc is supported by a separate gear disc bearing. This design provides a low component count and reduces wear. This type of kinematics can also be used in an electric motor with a high power density.
The cycloidal gear disc provides a high reduction ratio, which allows for compact construction. Unlike a ring gear, the cycloidal disc has fewer teeth. It also provides a higher reduction ratio, which is advantageous for high rotational input speed applications.
Cycloid gear discs have cylindrical holes, which allow for carrier pin devices to protrude through them. This is useful because the carrier pin devices can roll along the inside wall of the cylindrical hole in the gear disc.
A load plate is also used to provide anchorage for external structures. This plate contains threaded screw holes arranged 15mm away from the center. It has a 9mm external diameter and a 3mm through hole.

Transmission ratios up to 300:1

cycloidal gearboxes are used in a wide range of applications, from machine tools to medical imaging devices. Compared to planetary gearboxes, they offer superior positioning accuracy, torsional stiffness, backlash, and fatigue performance.
Cycloid gearboxes are also capable of transmitting more torque than planetary gears. In addition, they have a lower Hertzian contact stress and higher overload protection. Cycloid gearboxes are able to provide transmission ratios up to 300:1 in a small package.
Cycloid gears also have lower backlash over extended periods, making them an ideal choice for applications with critical positioning accuracy. Cycloid gearboxes also have good wear resistance, as well as low friction. Cycloid gears are lightweight and have good torsional stiffness, making them ideal for applications with heavy loads.
Cycloid gearboxes have several different designs. They can provide transmission ratios up to 300:1 without the need for additional pre-stages. Cycloid gears also require more accurate manufacturing processes than involute gears. Cycloid gearboxes can also be used for applications that require high power consumption, and can withstand shock loads.
Cycloid gearboxes can be adapted to fit most common servomotors. They have a modular design, all-round corrosion protection, and easy installation. Cycloid gears have a radial clamping ring, which reduces inertia by up to 39%.
CZPT Precision Europe GmbH, a subsidiary of CZPT Group, has developed an innovative online configurator to simplify the configuration of gearboxes. CZPT cycloidal gearheads are precision-built, robust, and reliable. They have a two-stage reduction principle, which minimises vibration and provides even force distribution.
Cycloid gears are capable of providing transmission ratios from 30:1 to 300:1. Cycloid gearboxes can achieve high gear ratios because they require fewer moving parts, and they have a low backlash.helical gearbox

Robustness against shock loads

Unlike conventional gearboxes that are easily damaged by shock loads, the cycloidal gearbox is extremely robust. It is a versatile solution that is ideally suited for handling equipment, food manufacturing, and machine tools.
The mechanical construction of a cycloidal gearbox consists of several mechanical components. These include cycloidal wheels, bearings, transformation elements, and needles. In addition, it has high torsional stiffness and tilting moment. It is also accompanied by highly nonlinear friction characteristic.
In order to assess the robustness of the cycloidal gearbox against shock loads, a mathematical model was developed. The model was used to calculate the stress distribution on the cycloid disc. This model can be used as a basis for more complex mechanical models.
The model is based on new approach, which allows to model stiction in all quadrants of the cycloid gear. In addition, it can be applied to actuator control.
The mathematical model is presented together with the procedure for measuring the contact stress. The results are compared to the measurement performed in the real system. The model and the measurement are found to be very close to each other.
The model also allows for the analysis of different gear profiles for load distribution. In addition, it is possible to analyze contact stresses with different geometric parameters. The mesh refinement along the disc width helps to ensure an even distribution of contact forces.
The stiction breakaway speed is calculated to the motor side. The non-zero current is then derived to the input side of the gearbox. In addition, a small steady phase is modeled during the speed direction transition. The results of the simulation are compared to the measurement. The results show that the model is extremely accurate.

Positioning accuracy

Getting the correct positioning accuracy from a cycloidal gearbox is no small feat. This is because the gears are compact, and the clearances are relatively small. This means you can expect a lot of torque from your output shaft. However, this is only part of the picture. Other concerns, such as backlash, kinematic error, and loading are all important considerations.
Getting the best possible positioning accuracy from a cycloidal gearbox means choosing a reducer that is well-made and correctly configured. A properly-selected reducer will eliminate repeatable inaccuracies and provide absolute positioning accuracy at all times. In addition, this type of gearbox offers several advantages over conventional gearboxes. These include high efficiency, low backlash, and high overload protection.
Getting the correct positioning accuracy from a gearbox also involves choosing a supplier that knows what it is doing. The best vendors are those who have experience with the product, offer a wide variety, and provide support and service to ensure the product is installed and maintained correctly. Another consideration is the manufacturer’s warranty. A reputable manufacturer will offer warranties for the gearbox. The aforementioned factors will ensure that your investment in a cycloidal gearbox pays off for years to come.
Getting the correct positioning accuracy from your cycloidal gearbox involves choosing a manufacturer that specializes in this type of product. This is particularly true if you are involved in robotics, automated painting, or any other industrial process that requires the best possible accuracy. A good manufacturer will offer the latest technology, and have the expertise to help you find the best solution for your application. This will ensure your product is a success from start to finish.helical gearbox

Size

Choosing the right size of cycloidal gearbox is important for its efficient operation. However, it is not a simple task. The process involves complex machining and requires the creation of many parts. There are different sizes of cycloidal gearboxes, and a few basic rules of thumb can help you choose the right size.
The first rule of thumb for choosing the right size of cycloidal gearboxes is to use a gearbox with the same diameter of the input shaft. This means that the gearbox must be at least 5mm thick. The cycloid will also require a base and a bearing to hold the driveshaft in place. The base should be large enough to house the pins. The bearing must be the same size as the input shaft.
The next rule of thumb is to have a hole in the cycloid for the output shaft. In this way, the output will be back-drivable and has low backlash. There should be at least four to six output holes. The size of the holes should be such that the centerline of the cycloid is equal to the size of the center of the bearing.
Using a Desmos graph, you can then create the gear parameters. The number of pins should be equal to the number of teeth in the cycloidal gear, and the size of the pins should be twice the size of the gear. The radius of the pins should be equal to the value of C from Desmos, and the size of the pin circle should be equal to the R value.
The final rule of thumb is to ensure that the cycloid has no sharp edges or discontinuities. It should also have a smooth line.
