Rack and pinion: Difference between revisions

A '''rack and pinion''' is a type of [[linear actuator]] that comprises a pair of [[gear]]s which convert rotational motion into linear motion. A circular gear called "the [[pinion]]" engages teeth on a linear "gear" bar called "the rack"; [[rotation]]al motion applied to the pinion causes the rack to move, thereby translating the rotational motion of the pinion into the linear motion of the rack.Rackpinion is the small gear whereas pinionrack is the gear of infinite diameter.
