RV reducer are used for the three joints of the waist and elbow of the leg of the robot with large torque, and the industrial robot with large load uses RV for one, two and three axes. Compared with the harmonic reducer, the key to the RV reducer lies in the processing technology and assembly process. RV reducer has higher fatigue strength, stiffness and life.

FAQ
What are the benefits of a cycloidal drive?
Cycloidal gearboxes offer several advantages, including high reduction ratios, compact design, exceptional load-bearing capacity, minimal backlash, and excellent shock resistance. These features make them ideal for applications requiring precise motion control and reliability under heavy loads.
Do cycloidal RV reducer gears have backlash?
The advantages of cycloidal gears over planetary gears:
Virtually backlash-free for the whole lifetime. Higher rigidity. More compact design.
How does a cycloid RV reducer work?
The input shaft is mounted eccentrically to a rolling-element bearing (typically a cylindrical roller bearing), causing the cycloidal disc to wobble in a circle. The cycloidal disc will independently rotate around the bearing as it is pushed against the ring gear.
What is RV speed reducer?
RV reducer is a high-precision control reducer with a cycloidal pin wheel reduction structure. Due to the large number of gears engaged at the same time, the reducer has the characteristics of small size, lightweight, high rigidity, and overload resistance.
