gear rack – A rack is a toothed bar or rod that can be regarded as a sector gear with an infinitely large 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 mechanism is used in automobiles to convert the rotation of the steering wheel into the left-to-right movement of the tie rod(s). Racks also feature in the idea of equipment geometry, where, for example, the tooth form of an interchangeable group of gears may be specified for the rack (infinite radius), and the tooth shapes for gears of particular actual radii are then derived from that. The rack and pinion equipment type is utilized in a rack railway.
