Working principle of electric hoist reducer

The reducer plays a 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, and its purpose is to reduce the speed and increase the torque. According to the different gear stages, it can be divided into single-stage and multi-stage reducers; according to the shape of the gear wheel, it can be divided into cylindrical gear reducer, bevel gear reducer and cone-cylindrical guide reducer; Divided into expansion, split and the same axis reducer. The reducer is a separate component consisting of a gear transmission, a worm drive, and a gear-worm drive enclosed in a rigid housing, and is often used as a reduction transmission between the prime mover and the work machine. The function of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator is widely used in modern machinery.

  The reducer is generally used for low-speed and high-torque transmission equipment. The motor, the internal combustion engine or other high-speed power is driven by the gears on the input shaft of the reducer to mesh the large gears on the output shaft to achieve the purpose of deceleration. The reducer will also have several pairs of identical principle gears to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
