Cycloidal gearbox for sale

Cycloidal gears are an excellent choice for those applications that require high gear ratios, good wear resistance, and low friction. They are typically used for applications where the gear ratio requirement is over 100:1. You can use the cycloidal gearbox for motion control in industrial automation applications across various disciplines and power transmission. Some popular applications include industrial robots, CNC precision machining, and welding positioning.

The gearbox is produced by Genius Zhenkang, an industrial manufacturer with a focus on high-quality hardware for use across various sectors of the economy. It has been producing high-quality parts for the last decade.

Features of Cycloidal Gearbox

  • High Precision

High precision gears can perform consistently over time without fail. The gears also produce the desired value every time you use the gearbox for your applications. Consistency is vital in ensuring that you get the same quality performance repeatedly.

  • Compact Size

Our gearboxes are compact. You do not need to modify your hardware to use our gearboxes, especially in robotics, where a little size deviation may be too expensive to adjust.

  • High Torque

Our gearboxes can maintain high torque in rotational machines such as robotic arms and mechanized systems. Therefore, in equipment where slowing down is likely to cause downtime or disruption of the process.

  • Long-lasting

Our gears are famed for their resistance to wear. They are also easy to lubricate, further enhancing their longevity. You can use the gears for a long period in highly demanding applications or applications where the environment may affect the performance of the gears.

Get quality, high-precision gearboxes for your industrial applications. We guarantee that they will perform as explained and help you deliver on your production goals.

Cycloidal gearbox design & working principle

  • The rotation of the servo motor is transmitted from the input gear to the spur gear, and it is decelerated according to the gear ratio of the input gear and the spur gear.
  • The crankshaft is directly connected with the spur gear and rotates at the same speed as the spur gear.
  • At the eccentric part of the crankshaft, there are two RV gears installed through needle bearings (two RV gears are installed to balance the force).
  • If the crankshaft rotates, the RV gear mounted on the eccentric part also performs eccentric movement (crankshaft movement).
  • On the other hand, the needle tooth groove on the inner side of the housing is provided with needle teeth arranged at equal distances, the number of which is one more than that of the RV gear.
  • If the crankshaft rotates one turn, the RV gear makes one turn of eccentric movement (crankshaft movement) while contacting the pin teeth. As a result, the RV gear rotates by a distance of 1 tooth in the direction opposite to the rotation direction of the crankshaft.
  • This rotation is transmitted to the shaft (output shaft) through the crankshaft, and the reduction is obtained. The reduction ratio is the number of needle teeth.
  • The final reduction ratio is the product of the reduction ratio of the first deceleration and the reduction ratio of the second deceleration.
