[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.
