The reducer plays the role 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. Shanghai reducer, worm reducer and planetary gear reducer According to the different transmission stages, it can be divided into single-stage and multi-stage reducer. The shape of the factory wheel can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical tooth pulley reducer; according to the transmission arrangement, it can be divided into For unfolding, split and coaxial reducer. The reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid casing. It is often used as a reduction drive between the prime mover and the working machine. It plays the role of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque.

Speed ratio = motor output revolutions ÷ reducer output revolutions ("speed ratio" is also called "transmission ratio")

1. Know the motor power, speed ratio and use coefficient, and find the torque of the reducer as follows: reducer torque = 9550 × motor power ÷ motor power input revolutions × speed ratio × use coefficient

2. Know the torque, the output revolutions of the reducer and the use coefficient, and find the motor power required by the reducer as follows: Motor power = torque ÷ 9550 × motor power input revolutions ÷ speed ratio ÷ use coefficient

It has a wide variety of models, and different types have different uses. There are many types of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the transmission type; single-stage and multi-stage reducers according to the number of transmission stages; cylindrical gear reducers according to the shape of the gear. Machine, bevel gear reducer and bevel-cylindrical gear reducer; according to the transmission arrangement, it can be divided into unfolded, split and coaxial reducers.
