齒輪和齒條對于工業生產而言都是相當重要的機械元件，對于齒輪和齒條的精度和性能通常都有較高的要求。在生產加工的過程中，哪怕是一絲一毫的偏差都會對產品的成型質量造成影響。但是在實際的生產過程中，往往會存在一些不確定的因素會造成齒輪和齒條的精度誤差。

Gears and racks are important mechanical components for industrial production, and there are usually high requirements for the accuracy and performance of gears and racks. During the production and processing process, even the slightest deviation can have an impact on the forming quality of the product. However, in the actual production process, there are often some uncertain factors that can cause accuracy errors in gears and racks.

引起齒輪和齒條誤差的原因不止一種，導軌絲杠廠家小編為您總結了以下的三種情況：

There are more than one reasons for gear and rack errors, and the editor of the guide screw manufacturer has summarized the following three situations for you:

滾齒機的齒形誤差

Tooth profile error of gear hobbing machine

機床是結合了展成運動結構和分齒運動結構的齒輪加工機床，像是滾齒機、插齒機等。對于這類型的機床而言，影響齒輪齒形誤差的因素通常大部分來自于刀具的制造刃磨。安裝誤差以及分齒傳動鏈的傳動誤差中的高次諧波分量，比如分度蝸桿的周期誤差和刀具傳動齒輪的齒距誤差。

A machine tool is a gear processing machine tool that combines generative motion structure and tooth splitting motion structure, such as gear hobbing machines, gear shaping machines, etc. For this type of machine tool, most of the factors that affect gear tooth shape error usually come from the manufacturing and grinding of the cutting tool. The installation error and the higher harmonic components in the transmission error of the toothed transmission chain, such as the periodic error of the indexing worm and the tooth pitch error of the tool transmission gear.

基節偏差

Basal deviation

基節偏差是指齒輪的實際基節和公稱基節的差。眾所周知的，漸開線齒輪嚙合的條件是兩齒輪的基節相等。若相互嚙合的一對齒輪中的其中一個齒輪產生了基節偏差，那么它們的輪齒在嚙合的進入或者退出中將產生瞬時傳動比變化，導致沖擊和振動的產生。

Base pitch deviation refers to the difference between the actual base pitch and the nominal base pitch of a gear. As is well known, the condition for involute gear meshing is that the base pitch of two gears is equal. If one of the gears in a pair of gears that mesh with each other produces a base pitch deviation, their teeth will undergo an instantaneous change in transmission ratio during the entry or exit of meshing, leading to the generation of shock and vibration.

齒距偏差

Tooth pitch deviation

齒距偏差指的是分度圓上實際齒距和公稱齒距的差，與基節偏差不同的是，基節是沿著嚙合線的方向進行測量，而齒距是在分度圓周節上進行測量。齒形誤差能夠反映出壓力角的誤差。所以，就評斷齒輪傳動的平穩性而言，有些情況能夠用齒距偏差取代基節偏差，齒距偏差更多的是由于機床分度運動機構的短周期誤差引起的。

Tooth pitch deviation refers to the difference between the actual tooth pitch and the nominal tooth pitch on the indexing circle. Unlike the base pitch deviation, which is measured along the direction of the meshing line, the tooth pitch is measured on the circumferential pitch of the indexing circle. The tooth profile error can reflect the error of pressure angle. So, in terms of evaluating the smoothness of gear transmission, in some cases, pitch deviation can be used instead of base pitch deviation, which is more caused by the short cycle error of the indexing motion mechanism of the machine tool.
