Introduction and Classification of Reducer

1.Introduction

The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration by meshing with the large gear on the output shaft through the gear with fewer teeth on the input shaft of the reducer. 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.

2.Classification

The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. There are many types, different models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers; according to the transmission stages, they can be divided into single-stage and multi-stage reducers; according to the gear shape, they can be divided into cylindrical gear reducers. The speed reducer, the bevel gear reducer and the bevel-cylindrical gear reducer; according to the arrangement of the transmission, it can be divided into the expansion type, the split type and the coaxial type reducer.
