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.

齿条是一种特殊的齿轮，齿分布在棒状的本体上。齿条又分为正齿轮齿条和斜齿轮齿条，分别与正齿轮和斜齿轮配对；齿条的齿形是直线而不是渐开线（对于齿面来说是平面），相当于分度圆半径为无穷大的圆柱齿轮。特点：（1）由于齿条齿形是一条直线，齿形上各点压力角相同，压力角等于齿形的倾角。这个角度称为齿廓角，标准值为20°。（2）任意平行于齿顶线的直线，其齿距和模数相同。（3）与齿顶线平行且齿厚等于齿隙宽度的直线称为分度线（中心线），是计算齿条尺寸的基线。

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

参数选择：（1）齿轮的跳动、全齿深、共法线、齿向是否合格，齿跳动、节距误差是否超差。（2）齿轮齿条安装后的安装距离是否合适。（3）齿条与齿轮的啮合间隙宜取0.25*模数。（4）齿条的全齿深、跳动、法线，特别是齿向是否合格
