Reducer plays the role of matching speed and transmitting torque between prime mover and working machine or actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety, different models and different uses. There are many kinds of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the transmission type.
According to the different transmission stages, it can be divided into single-stage and multi-stage reducers; According to the gear shape, it can be divided into cylindrical gear reducer, conical gear reducer and conical cylindrical gear reducer. According to the layout of transmission, it can be divided into deployable reducer, shunt reducer and coaxial reducer.
