A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version

Reduction gears are an arrangement by which an input speed can be lowered for a requirement of slower output speed, with

 The use of a gear reducer occurs when the drive gear is smaller and has fewer teeth than the driven gear. Reduc

A gear reducer is a mechanical system of gears in an arrangement such that input speed can be lowered to a slower o
