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.


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.
