The reducer is incredible. It has the function of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. . If it is different according to the number of transmission stages, it can be divided into single-stage and multi-stage reducers; if it is in accordance with the shape of the gear wheel, it can be divided into cylindrical gear reducer, bevel gear reducer and cone-cylindrical guide reducer; The layout can be divided into expansion, split and synchronous shaft reducers. Its reducer is a separate component consisting of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing. It can often be used as a reduction gear between the prime mover and the work machine.
