The purpose of using it is to reduce the speed. According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers. The factory wheel shape can be divided into cylindrical gear reducers, bevel gear reducers and conical-cylindrical gear reducers; according to the transmission layout, it can be divided into expansion type, split type and co-axial reducers. The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery.
