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 transmitted through 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.

The reducer is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor to a desired number of revolutions and obtain a mechanism of a large torque.
