齒輪是互相嚙合的有齒的機(jī)械零件，它在機(jī)械傳動乃整個(gè)機(jī)械行業(yè)，日常生活中都有著很廣泛的應(yīng)用，齒輪的應(yīng)用歷史悠久，今也是機(jī)械行業(yè)中不可或缺的重要零件。接下來導(dǎo)軌絲杠廠家為您講解一下齒輪齒條的分類及主要應(yīng)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.

齒輪齒條工作原理：

Operating principle of gear and rack:

齒輪齒條工作原理是將齒輪的回轉(zhuǎn)運(yùn)動轉(zhuǎn)變?yōu)辇X條的往復(fù)直線運(yùn)動，或?qū)X條的往復(fù)直線運(yùn)動轉(zhuǎn)變?yōu)辇X輪的回轉(zhuǎn)運(yùn)動。

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.

齒輪齒條機(jī)構(gòu)：

Rack and pinion mechanism:

齒輪齒條機(jī)構(gòu)是由齒輪和齒條構(gòu)成的，齒輪前面我們有很詳細(xì)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(dāng)于分度圓半徑為無窮大圓柱齒輪。

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.

齒條的主要特點(diǎn)

Main features of rack

由于齒條齒廓為直線，所以齒廓上各點(diǎn)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(biāo)準(zhǔn)值為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 °.

與齒頂線平行的任一條直線上具有相同的齒距和模數(shù)。

Any straight line parallel to the tooth top 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(jì)算齒條尺寸的基準(zhǔn)線。

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.
