齒輪是互相嚙合的有齒的機械零件，它在機械傳動乃至整個機械行業，日常生活中都有著很廣泛的應用，齒輪的應用歷史悠久，至今也是機械行業中不可或缺的重要零件。接下來導軌絲杠廠家為您講解一下齒輪齒條的分類及主要應用。

Gears are mechanical parts that mesh with each other and have teeth. They are widely used in mechanical transmission and even in the entire mechanical industry, and in daily life. The application of gears has a long history and is still an indispensable and important part in the mechanical industry. Next, the guide screw manufacturer will explain to you the classification and main applications of gears and racks.

齒輪齒條工作原理：

Working principle of gear and rack:

齒輪齒條工作原理是將齒輪的回轉運動轉變為齒條的往復直線運動，或將齒條的往復直線運動轉變為齒輪的回轉運動。

The working principle of gears and racks is to transform the rotational motion of gears into the reciprocating linear motion of racks, or to transform the reciprocating linear motion of racks into the rotational motion of gears.

齒輪齒條機構：

Gear and rack mechanism:

齒輪齒條機構是由齒輪和齒條構成的，齒輪前面我們有很詳細的講解。齒條分直齒齒條和斜齒齒條，齒條的齒廓為直線而非漸開線，相當于分度圓半徑為無窮大圓柱齒輪。

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

齒條的主要特點

The main characteristics of the rack

由于齒條齒廓為直線，所以齒廓上各點具有相同的壓力角，且等于齒廓的傾斜角，此角稱為齒形角，標準值為20°。

Since the rack tooth profile is a straight line, all points on the tooth profile have 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 °.

與齒頂線平行的任一條直線上具有相同的齒距和模數。

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

與齒頂線平行且齒厚等于齒槽寬的直線稱為分度線（中線），它是計算齒條尺寸的基準線。

The straight line parallel to the tooth crest line and with a tooth thickness equal to the width of the tooth groove is called the indexing line (centerline), which is the reference line for calculating the size of the gear rack.
