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.
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.
- Alignment: Ensure that the gearbox is properly aligned with other components to prevent misalignment-related issues.
- Regular Service: Follow the manufacturer’s recommended service intervals for more in-depth inspections and maintenance tasks.
Regular and proactive maintenance can extend the lifespan of cycloidal gearboxes, minimize downtime, and maintain their efficiency and performance over time.
How Does a Cycloidal Gearbox Work?
A cycloidal gearbox operates on the principle of cycloidal motion to transmit rotational power. It consists of a set of components that work together to achieve smooth and efficient motion transmission:
- High-Speed Input Shaft: The gearbox is connected to a high-speed input shaft, typically driven by an electric motor or another power source.
- Cycloidal Pins or Rollers: Surrounding the input shaft are a series of cycloidal pins or rollers arranged in a circular pattern. These pins interact with the lobed profiles of the outer stationary ring.
- Outer Stationary Ring: The outer ring remains stationary and contains lobed profiles. The lobes are designed in a way that allows them to engage with the cycloidal pins as they rotate.
- Motion Transmission: As the input shaft rotates, it causes the cycloidal pins to move along the circular path. The interaction between the cycloidal pins and the lobed profiles of the outer ring results in a unique motion known as epicycloidal or hypocycloidal motion.
This motion generates torque that is transferred from the input shaft to the output shaft of the gearbox. The main advantage of a cycloidal gearbox is its ability to provide high torque output in a compact design. The multiple points of contact between the pins and the lobes distribute the load, enhancing the gearbox’s load-carrying capacity.
Cycloidal gearboxes are known for their smooth and controlled motion, making them suitable for applications requiring precise positioning and high torque capabilities, such as robotics, automation, and industrial machinery.

FAQ
Q:Key points of selection of planetary reducer
A:1. Frame number determined by torque: the power source will have the effect of torque amplification after deceleration ratio. The output torque value of the reducer is proportional to the deceleration ratio, and the larger the ratio, the higher the torque value will be; But the gear group of the reducer has the limit, so the rated output torque of the planetary reducer is to say that the product can work stably under the data operation, so the box number must be selected according to the demand torque.
2. According to the accuracy to determine the model: in the process of automation will need positioning, when the positioning accuracy requirements are higher, you need to choose a higher level of products, and vice versa. The precision of the planetary reducer is called the “backgap”, which refers to the gap of the gear group. The definition is the Angle value that the output shaft of the planetary reducer can rotate when the input end is fixed. The smaller the return clearance is, the higher the accuracy is and the higher the cost is. The user can choose the right accuracy according to their actual situation.
3. According to the installation size selection: that is, the size of the front end of the servo motor. The input end of the planetary reducer must match the output end of the servo motor.
4. According to the appearance selection: according to customer demand output shaft and connecting surface has a standard series for users to choose, can also be customized according to user special needs.
5. According to the axial and radial force selection: the life of the planetary reducer is affected by the internal bearing, bearing life can be calculated through the load and speed, when the axial and radial force load of the reducer is higher, the bearing life will be shortened, at this time it is recommended to choose a large product.

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.
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.
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.

How to Calculate Transmission Ratio for a Cycloidal Gearbox
Using a cycloidal gearbox can be very useful in a wide variety of situations. However, it’s important to understand how to use it properly before implementing it. This article discusses the benefits of using a cycloidal gearbox, how to calculate the transmission ratio, and how to determine the effects of dynamic and inertial forces on the gearbox.
Dynamic and inertial effects
Various studies have been done to study the dynamic and inertial effects of cycloidal gearboxes. These studies have been performed using numerical, analytical and experimental methods. Depending on the nature of the load and its distribution along the gear, a variety of models have been developed. These models use finite element method to determine accurate contact stresses. Some of these models have been developed to address the nonlinear elasticity of contacts.
Inertial imbalance in a cycloidal gearbox causes vibration and can affect the efficiency of the device. This can increase mechanical losses and increase wear and tear. The efficiency of the device also depends on the torque applied to the cycloidal disk. The effectiveness of the device increases as the load increases. Similarly, the nonlinear contact dynamics are also associated with an increase in efficiency.
A new model of a cycloidal reducer has been developed to predict the effects of several operational conditions. The model is based on rigid body dynamics and uses a non-linear stiffness coefficient. The model has been validated through numerical and analytical methods. The model offers drastic reduction in computational costs. The model allows for a quick analysis of several operational conditions.
The main contribution of the paper is the investigation of the load distribution on the cycloidal disc. The study of this aspect is important because it allows for an analysis of the rotating parts and stresses. It also provides an indication of which gear profiles are best suited for optimizing torque transmission. The study has been conducted with a variety of cycloidal gearboxes and is useful in determining the performance of different types of cycloidal gearboxes.
To study the load distribution on the cycloidal disc, the authors investigated the relationship between contact force, cycloidal gearboxes and different gear profiles. They found that the non-linear contact dynamics have a large impact on the efficiency of a cycloidal gearbox. The cycloidal gearbox is an ideal solution for applications that involve highly dynamic servos. It can also be used in machine tool applications and food processing industries.
The study found that there are three common design principles of cycloidal reducers. These are the contact force distribution, the speed reduction and the trochoidal profile of the cycloidal disc. The trochoidal profile has to be defined carefully to ensure correct mating of the rotating parts. The trochoidal profile provides an indication of which gear profiles are best for optimizing torque transmission. The contact force distribution can be improved by refining the mesh along the disc’s width.
As the input speed increases, the efficiency of the reducer increases. This is because contact forces are constantly changing in magnitude and orientation. A cycloidal reducer with a one tooth difference can reduce input speed by up to 87:1 in a single stage. It also has the ability to handle high-cycle moves without backlash.
Transmission ratio calculation
Getting the correct transmission ratio calculation for a cycloidal gearbox requires a good understanding of what a gearbox is, as well as the product that it is being used for. The correct ratio is calculated by dividing the output speed of the output gear by the input speed of the input gear. This is usually accomplished by using a stopwatch. In some cases, a catalog or product specification may be required. The correct ratio is determined by a combination of factors, such as the amount of torque applied to the mechanism, as well as the size of the gears involved.
A cycloidal gear is a type of gear tooth profile that can be represented using a spline. It is also possible to model a gear with a cycloidal profile by using a spline to connect points against the beginning of a coordinate system. This is important in the design and functionality of a gear.
There are many different gears used in machines and devices. These include the herringbone gear, the helical gear and the spiral bevel gear. The best transmission ratios are typically obtained with a cycloidal gearbox. In addition to ensuring the accuracy of positioning, a cycloidal gearbox provides excellent backlash. Cycloid gears have a high degree of mechanical efficiency, low friction, and minimal moment of inertia.
A cycloidal gearbox is often referred to as a planetary gearbox, though it is technically a single-stage gearbox. In addition to having a ring gear, the gearbox has an eccentric bearing that drives the cycloidal disc in an eccentric rotation. This makes the cycloidal gearbox a good choice for high gear ratios in compact designs.
The cycloid disc is the key element of a cycloidal gearbox. The cycloid disc has n=9 lobes, and each lobe of the disc moves by a lobe for every revolution of the drive shaft. The cycloid disc is then geared to a stationary ring gear. The cycloidal disc’s lobes act like teeth on the stationary ring gear.
There are many different gears that are classified by the profile of the gear teeth. The most common gears are the involute and helical gears. Most motion control gears include spur designs. However, there are many other types of gears that are used in various applications. The cycloidal gear is one of the more complicated gears to design. The cycloid disc’s outline can be represented using markers or smooth lines, though a scatter chart will also do.
The cycloid disc’s lobes rotate on a reference pitch circle of pins. These pins rotate 40 deg during the eccentric rotation of the drive shaft. The pins rotate around the disc to achieve a steady rotation of the output shaft.
The cycloid disc’s other obvious, and possibly more important, feature is the’magic’ number of pins. This is the number of pins that protrude through the face of the disc. The disc has holes that are larger than the pins. This allows the pins to protrude through the disc and attach to the output shaft.
Application
Whether you’re building a robot drive or you’re simply looking for a gearbox to reduce the speed of your vehicle, a cycloidal gearbox is a great way to achieve a high reduction ratio. Cycloidal gearboxes are a low-friction, lightweight design that has an extremely stable transmission. They are suitable for industrial robots and can be used in many applications, including positioning robots.
Cycloidal gearboxes reduce speed by using eccentric motion. The eccentric motion enables the entire internal gear to rotate in wobbly cycloidal motion, which is then translated back into circular rotation. This eliminates the need for stacking gear stages. Cycloidal gearboxes also have less friction, higher strength, and greater durability than conventional gearboxes.
The cycloidal gearbox is also used in a number of applications, including marine propulsion systems, and robot drives. Cycloidal gearboxes reduce vibration by using offset gearing to cancel out vibrations.
Cycloidal gears have lower friction, higher strength, and better torsional stiffness than involute gears. They also have a reduced Hertzian contact stress, making them better than involute gears for use with shock loads. They also have a smaller size and weight than conventional gearboxes, and they have a higher reduction ratio than involute gears.
Cycloidal gears are typically used to reduce the speed of motors, but they also offer a number of other advantages. Cycloidal gearboxes have a smaller footprint than other gearboxes, allowing them to fit into confined spaces. They also have low backlash, allowing for precise movement. Cycloidal gears have a higher efficiency, resulting in lower power requirements and lower wear.
The cycloidal disc is one of the most important components of the gearbox. Cycloidal discs are normally designed with a short cycloid, which minimizes the eccentricity of the disc. They are also designed with a shortened flank, resulting in better strength and less stress concentration. Cycloidal discs are typically geared to a stationary ring gear. The cycloid is designed to roll around the stationary ring pins, which push against the circular holes in the disc. Cycloidal gearboxes typically employ two degrees of shift.
Cycloidal drives are ideal for heavy load applications. They also have high torsional stiffness, which makes them highly resistant to shock loads. Cycloidal drives also offer a high reduction ratio, which can be achieved without the need for a large input shaft. They are also compact and have a high service life.
The output shaft of a cycloidal gearbox always has two degrees of shifting, which ensures that the input and output shafts always rotate at a different speed. The output shaft would be a pin casing around the drive disks, which would also allow for easy maintenance.
Cycloidal gearboxes are also very compact and lightweight, so they are ideal for use in industrial robots. The cycloidal gearbox reducer is the most stable, low-vibration reducer in industrial robots, and it has a wide transmission ratio range.

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.
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.

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.

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.

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.

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.

- High Positional Accuracy: Cycloidal gearboxes offer high positional accuracy, making them suitable for applications that require precise positioning and movement.
- Backlash Reduction: The design of cycloidal gearboxes minimizes backlash, ensuring that there is minimal play between gears. This is crucial for maintaining accuracy in precision applications.
- Smooth and Controlled Motion: Cycloidal gearboxes provide smooth and controlled motion with minimal vibration, which is essential for delicate operations and precision machinery.
- Compact Design: Their compact design allows cycloidal gearboxes to be integrated into tight spaces without sacrificing performance. This is especially valuable in applications where space is limited.
- Repeatable Performance: Cycloidal gearboxes offer consistent and repeatable performance, which is vital for maintaining precision over multiple cycles.
- Low Backlash: The low backlash characteristic of cycloidal gearboxes ensures that there is minimal lost motion, contributing to their precision performance.
- High Torque Density: Despite their compact size, cycloidal gearboxes can handle high torque loads, making them suitable for applications that require both precision and power.
- Reduced Wear: The rolling contact design of cycloidal gears reduces wear and extends the lifespan of the gearbox, which is crucial for precision applications that demand consistent performance over time.
Overall, cycloidal gearboxes are a reliable choice for precision applications that require accurate positioning, controlled motion, and consistent performance.
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.
