The RV reducer is composed of the front stage of a planetary gear reducer and the rear stage of a cycloid reducer. The RV reducer has a compact structure, a large transmission ratio, and a transmission mechanism with a self-locking function under certain conditions. One of the most commonly used reducers with low vibration, low noise and low energy consumption.

RV transmission is a new type of transmission. It is developed on the basis of traditional needle pendulum planetary transmission. It not only overcomes the shortcomings of general needle pendulum transmission, but also has small size, light weight, large transmission ratio range, and long life. A series of advantages such as long, stable accuracy, high efficiency, stable transmission and so on. Increasingly attracting widespread attention at home and abroad. The RV reducer is composed of a cycloid pin wheel and a planetary carrier. Its small size, strong impact resistance, large torque, high positioning accuracy, small vibration, and large reduction ratio are widely used in industrial robots, machine tools, and medical testing. Equipment, satellite receiving system and other fields. It has much higher fatigue strength, stiffness and life than the harmonic drive commonly used in robots, and the accuracy of the return difference is stable. Unlike the harmonic drive, the motion accuracy will be significantly reduced with the increase of use time, so many countries in the world RV reducers are mostly used for high-precision robot transmission. Therefore, this type of RV reducer has a tendency to gradually replace harmonic reducers in advanced robot transmission.
