A rack and pinion is a type of
linear actuator that comprises a pair of
gears which convert rotational motion into linear
motion. The circul
ar
pinion engages teeth on a linear "gear" bar–the
rack. Rotational motion applied to the pinion
will
cause the rack to
move to the side, up to the limit of its travel. For
example, in a rack railway, the rotation of a pinion
mounted on a locomotive or a railcar engages a rack
between the rails and pulls a train along a steep slope.
