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.
