A flat or straight bars, when it has a series of equally spaced teeth, known as the rack. Rack and pinion gear meshing of the strip in a straight line with the gear, the gear can be said of the pitch in size into the special circumstances of infinity. Rack and pinion gear can be divided into straight and helical rack rack, respectively, with the spur gear and Helical Gear paired; rack tooth profile is linear rather than involute (compared to the tooth surface in terms of plane ), equivalent to pitch circle radius is infinite cylindrical gear.
