齿轮是互相啮合的有齿的机械零件，它在机械传动乃整个机械行业，日常生活中都有着很广泛的应用，齿轮的应用历史悠久，今也是机械行业中不可或缺的重要零件。接下来导轨丝杠厂家为您讲解一下齿轮齿条的分类及主要应用。

Gear is a mechanical part with teeth that mesh with each other. It is widely used in mechanical transmission and even in the whole mechanical industry and in daily life. The application of gear has a long history, and it is also an indispensable and important part in the mechanical industry. Next, the guide screw manufacturer will explain the classification and main application of gear and rack for you.

齿轮齿条工作原理：

Operating principle of gear and rack:

齿轮齿条工作原理是将齿轮的回转运动转变为齿条的往复直线运动，或将齿条的往复直线运动转变为齿轮的回转运动。

The working principle of gear and rack is to change the rotary motion of gear into the reciprocating linear motion of rack, or the reciprocating linear motion of rack into the rotary motion of gear.

齿轮齿条机构：

Rack and pinion mechanism:

齿轮齿条机构是由齿轮和齿条构成的，齿轮前面我们有很详细的讲解。齿条分直齿齿条和斜齿齿条，齿条的齿廓为直线而非渐开线，相当于分度圆半径为无穷大圆柱齿轮。

The rack and pinion mechanism is composed of gear and rack. We have explained the gear in detail before. The rack is divided into straight rack and helical rack. The tooth profile of the rack is straight rather than involute, which is equivalent to a cylindrical gear with an infinite radius of indexing circle.

齿条的主要特点

Main features of rack

由于齿条齿廓为直线，所以齿廓上各点具有相同的压力角，且等于齿廓的倾斜角，此角称为齿形角，标准值为20°。

Because the rack tooth profile is straight, each point on the tooth profile has the same pressure angle and is equal to the inclination angle of the tooth profile. This angle is called the tooth profile angle, and the standard value is 20 °.

与齿顶线平行的任一条直线上具有相同的齿距和模数。

Any straight line parallel to the tooth top line has the same tooth pitch and modulus.

与齿顶线平行且齿厚等于齿槽宽的直线称为分度线（中线），它是计算齿条尺寸的基准线。

The straight line parallel to the tooth top line and the tooth thickness equal to the width of the tooth slot is called the indexing line (center line), which is the reference line for calculating the size of the rack.
