A rack is a special gear with teeth distributed on a bar-shaped body. Racks are also divided into spur gear racks and helical gear racks, which are paired with spur gears and helical gears respectively; the tooth profile of the rack is a straight line rather than an involute (for the tooth surface, it is a plane), which is equivalent to a cylindrical gear with an infinite radius of the indexing circle. Features: (1) Since the rack tooth profile is a straight line, each point on the tooth profile has the same pressure angle, which is equal to the inclination angle of the tooth profile. This angle is called the tooth profile angle, and the standard value is 20°. (2) Any straight line parallel to the tooth top line has the same tooth pitch and module. (3) The straight line parallel to the tooth top line and with the tooth thickness equal to the tooth space width is called the index line (center line), which is the baseline for calculating the rack size.

Parameter selection: (1) Whether the runout, full tooth depth, common normal, and tooth direction of the gear are qualified, and whether the tooth runout and pitch error are out of tolerance. (2) Whether the installation distance of gears and racks is appropriate after installation. (3) The meshing clearance of rack and gear should be 0.25*modulus. (4) Whether the full tooth depth, runout, common normal, especially the tooth direction of the rack are qualified
