[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is widely used in modern machinery, especially in situations where it is necessary to reduce the speed and increase the torque. It mainly uses 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 to reduce the speed of the motor, internal combustion engine or other high-speed power, while increasing the torque. Its working principle is based on the transmission ratio effect produced by the meshing of gears or worms with different numbers of teeth. There are many types of reducers, and you can choose the appropriate type according to your actual needs. There are many ways to connect reducers, each of which has its specific application scenarios and advantages and disadvantages, such as flange connection, bearing connection, drum connection, etc.
