Now mature and standardized gear reducer are: cylindrical gear reducer, a turbine reducer, planetary reducer, planetary gear reducer, RV reducer, cycloid pin wheel reducer, and harmonic gear reducer. Among them, RV reducer and harmonic reducer are two important reducers in precision reducer.
In the robot joint , the RV reducer is generally placed in the seat, large arm, shoulder, etc.
The harmonic reducer is placed in the forearm, wrist or hand;Planetary reducers are commonly used in cartesian robots.They are used In emerging industries such as aerospace and medical equipment.
