A reduction gear box is an element of a mechanical system of gears and shafts used to reduce the rotational speed of the input shaft to a slower rotational speed on the output shaft. This reduction in output speed helps increase torque. Reduction gears box are usually used in automobile and truck drive trains to cut down the high rotational speeds of the engine to a usable, slower speed at the tires. Click
