Cyclo Drive Gearbox

The cyclo drive speed reducer is a novel transmission mechanism with the principle of K-H-V less tooth difference planetary transmission and the meshing of cycloid needle and tooth.

It is widely used in textile printing and dyeing, light industry food, metallurgical miners, petrochemical, lifting transportation and engineering machinery and other fields.

Cycloidal gear boxes, also known as cycloidal gear boxes or planetary gear boxes, are used in robotic applications. Compared with traditional gear boxes, they have many advantages, such as: wide transmission ratio range; High efficiency and small size.

They can withstand higher loads and impact forces than conventional gear drives because multiple cylinders are in contact at any given time. This allows for higher power density and smaller overall size while maintaining good torsional stiffness in dynamic applications.

cyclo drives features



High speed ratio and high efficiency


The single stage transmission can achieve the reduction ratio of 1:87 and the efficiency is above%90. If multistage transmission is adopted, the deceleration ratio will be greater.Noise:All key components are finished by precisely machining , accurate assembly and finally tested .



Compact structure, small volume
Because of the principle of planetary transmission, the input shaft and the output shaft are on the same axis, so the structure is compact and the volume is small.


Low running noise and low noise
The mechanism of cycloidal needle tooth engagement is large, the overlap coefficient is large, and the mechanism is stable.



Reliable use, long life
Because the main parts are bearing steel, after quenching treatment (HRC58-62) to obtain high strength, and the part of transmission contact with rolling friction, so long durable life,


Reasonable design, convenient maintenance, easy decomposition and installation, minimum number of parts and simple lubrication, make cycloidal pinwheel reducer trusted by users.

Cyclo drive gear motor


The cyclo drive gear motor is a type of reduction motor that can be used in many applications where positioning accuracy and performance are critical, such as robotics and machine tools. This type of reducer has high efficiency, zero clearance and very large torque capability.

They also have a torque limiter that can be set for maximum protection. These features make them ideal for applications where system safety is important.

The key to the unmatched performance and reliability of the cyclo drive is that 67% of the decelerating components are always in contact, compared to gear designs that use only limited tooth contact. The “cycloid disk”, which is a cyclo drive gear, has a unique smooth curve (epitrochoid parallel curve) that differs from the curvature of the typical involute gear.

About Us

Harmonic Drive Vs Cycloid

Both harmonic drive and cycloid drive are compact high ratio drives, which are suitable for anthropomorphic robots. However, a recent study has shown that cycloidal transmission is more efficient than harmonic transmission.

A cycloid drive is a mechanical gear system that uses a ring gear housing (similar to a planetary gear drive) that holds an eccentric CAM around the outer ring. When the eccentric CAM rotates, it deforms the cycloidal disc into an elliptical shape. The cycloidal disc then engages with the inner teeth of the annular gear housing.

Cycloidal drive Reverse drive: Unlike harmonic drive, cycloidal drive can be reversed without causing any gap or notch behavior on the output shaft.

cyclo drive reducer

Sumitomo Cyclo Drive (Cycloidal reduction motor) is the premier in-line reducer that delivers quiet, efficient and reliable performance. They exceed all expectations of conventional decelerators that use common involute gear designs. The key to its superior performance and reliability is that Cyclo’s deceleration components operate under compression rather than shear.

sumitomo cyclo drive

Motor cyclo drive is a speed reducer and reduction motor with zero backlash, high torque capability and compact design. It is a gear-based drive that uses cycloidal teeth to push force through many teeth at once, rather than a single tooth. The cycloidal shape of the teeth allows for larger contact areas than conventional gear-based transmissions, which results in lower noise and wear.

These unique design features enable the Cyclo to withstand impact loads in excess of 500% of its rating and deliver superior performance, reliability and long life in the most severe applications.

In addition to this high torque capability, Cyclo’s cycloid line design eliminates gear separation forces and reduces vibration and noise levels.
