What Is A Reducer Jun 03, 2020

What is a reducer


The reducer plays a role in matching the rotation speed and transmitting torque between the prime mover and the working machine or actuator. The reducer is a relatively sophisticated machine. The purpose of using it is to reduce the rotation speed and increase the torque. According to the different transmission stages, it can be divided into single-stage and multi-stage reducers; according to the shape of the gear factory, it can be divided into cylindrical gear reducers, conical gear reducers and conical-cylindrical gear reducers; It is divided into unfolding type, shunt type and co-axial shaft reducer. The reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing. It is often used as a deceleration drive between the prime mover and the working machine. It plays a role in matching the rotation speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.


The reducer is generally used in low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is passed through the gear with a small number of teeth on the input shaft of the reducer to mesh with the large gear on the output shaft. The reducer will also have several pairs of gears with the same principle to achieve the desired reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.


The reducer is a relatively precise machine, and its purpose is to reduce the speed and increase the torque. It has many types and different models, and different types have different uses. There are many types of reducers, according to the transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to the different transmission stages can be divided into single-stage and multi-stage reducer; according to the shape of the gear can be divided into cylindrical gear reduction Reducer, conical gear reducer and conical-cylindrical gear reducer; according to the layout of the transmission, it can be divided into unfolded, split and coaxial reducers
