gear rack – A rack is a toothed bar or rod which can be regarded as a sector gear with an infinitely huge radius of curvature. Torque could be converted to linear pressure by meshing a rack with a pinion: the pinion turns; the rack movements in a straight line. Such a system is used in automobiles to convert the rotation of the steering wheel into the left-to-right motion of the tie rod(s). Racks also feature in the theory of equipment geometry, where, for instance, the tooth shape of an interchangeable group of gears may be specified for the rack (infinite radius), and the tooth styles for gears of particular real radii are then produced from that. The rack and pinion equipment type is employed in a rack railway.
