Reducer between prime mover and work machine or actuator has a function in matching speed and transfer torque reducer is a relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque. According to the transmission series can be divided into single stage and multi-stage speed reducer; According to the shape of gear wheel, it can be divided into cylindrical gear reducer, conical gear reducer and cone-cylindrical gear reducer; According to the layout of the transmission, it can be divided into expansion, shunt and coaxial reducer. Reducer is a kind of the closed in rigid casing of gear transmission, worm drive and gear - worm drive composed of independent components, commonly used for the original reduction drive device between moving parts and working machine. The function of matching speed and transfer torque between the original motivation and the working machine or actuator is widely used in modern machinery.
