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.

齒條是一種特殊的齒輪，齒分布在棒狀的本體上。齒條又分為正齒輪齒條和斜齒輪齒條，分別與正齒輪和斜齒輪配對；齒條的齒形是直線而不是漸開線（對於齒麵來說是平麵），相當於分度圓半徑為無窮大的圓柱齒輪。特點：（1）由於齒條齒形是一條直線，齒形上各點壓力角相同，壓力角等於齒形的傾角。這個角度稱為齒廓角，標準值為20°。（2）任意平行於齒頂線的直線，其齒距和模數相同。（3）與齒頂線平行且齒厚等於齒隙寬度的直線稱為分度線（中心線），是計算齒條尺寸的基線。

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
