Precision rack and pinion gear is a special type of gear with teeth distributed on a bar shaped body. Gears are also divided into straight toothed racks and helical toothed racks, which are paired with straight toothed cylindrical gears and helical toothed cylindrical gears respectively; The tooth profile of the rack is a straight line rather than an involute (or a plane for the tooth surface), which is equivalent to a cylindrical gear with an infinite pitch circle radius.
