對于使用了齒形同步帶的紡織企業(yè)有重要的指導(dǎo)意義。
There is an important guiding significance for the use of the synchronous toothed belt of textile enterprises.
同步帶有單面有齒和雙面有齒兩種，簡稱單面帶和雙面帶。
Synchronization with a single side of a tooth and teeth two kinds of double-sided, single-sided and double-sided tape or band.
雙面帶又有對稱齒型（DA）和交錯齒型（DB）之分。
Double-sided tape and symmetrical tooth type (DA) and staggered tooth type (DB) division.
同步帶齒有梯形齒同步帶和弧形齒同步帶兩類。

梯形齒同步帶傳動已有標(biāo)準(zhǔn)（GB11361～11362–89）。
The existing standard trapezoidal toothed synchronous belt transmission (GB11361 ~ 11362 - 89).
在規(guī)定張緊力下，相鄰兩齒中心線的直線距離稱為節(jié)距，以p表示。節(jié)距是同步帶傳動最基本的參數(shù)。
Under tension, straight-line distance of two adjacent tooth center line called the pitch, expressed in P. Pitch is the most basic parameters of synchronous belt transmission.
當(dāng)同步帶垂直其底邊彎曲時，在帶中保持原長度不變的周線，稱為節(jié)線，節(jié)線長以LP表示。同步帶帶輪的齒形推薦采用漸開線齒形，可用范成法加工而成。也可以使用直邊齒形。
When the synchronous belt is vertical to the bottom edge bending, keep the original length invariant contour in the belt, known as the pitch line, pitch length in LP. Synchronous belt tooth shaped belt wheel to recommend the use of involute tooth profile, the available generating and processing. Can also use straight tooth.

There are more and more textile equipment using the tooth shape belt.
3、齒形同步帶使用中的”爬齒”現(xiàn)象產(chǎn)生的機理
3, the toothed belt in use "climbing gear" phenomena
同步帶傳動雖然有很多的優(yōu)點，但也存在很多缺陷，如：壽命短，不耐磨，齒剝離現(xiàn)象嚴(yán)重，嚙合、跳齒、振動等不良情況。
Synchronous belt drive has many advantages, but there are many defects, such as: life is short, do not wear, tooth stripping phenomenon is serious, meshing, jumping, vibration and other adverse conditions.
隨著同步帶傳動過程和傳遞運動中所產(chǎn)生的傳動誤差，會出現(xiàn)同步帶擱在齒槽齒廓表面上，由于N多次的誤差累積．就會使帶齒爬到帶輪頂圓上，使同步齒形帶在帶輪頂圓上滑動的跳齒．這就是所謂“爬齒”現(xiàn)象；
With synchronous belt transmission process and transfer transmission errors generated in the movement, there will be put on the tooth synchronous belt tooth profile surface, due to the cumulative error of N several times. It will make the toothed belt wheel on the climb to the top circle, the synchronous toothed belt jump teeth sliding on the belt pulley on the top circle. This is the so-called "climbing gear" phenomenon;
除了以上原因可能產(chǎn)生“爬齒”現(xiàn)象外，還有：
In addition to the above reasons "climbing gear" phenomenon, and:
3．1同步帶張力不適當(dāng)。
3.1 synchronous belt tension is not appropriate.
3．2同步帶或齒形輪表面有油污
3.2 synchronous belt or gear wheel surface with oil
3．3傳動的齒形輪與齒形輪不在同一個平面上（即平行度差）；
The 3.3 transmission gear wheel and the gear wheel is not in the same plane (which is parallel to the poor);
3．4同步齒形帶屬于彈性體，在制造和傳力過程中帶齒的節(jié)距會發(fā)生變化，造成同步帶齒與帶輪齒在嚙合時節(jié)距不等，出現(xiàn)節(jié)距誤差。過大的節(jié)距誤差，會使傳動不平穩(wěn)，產(chǎn)生振動及爬齒現(xiàn)象；
3.4 synchronous toothed belt belongs to the elastomer, with teeth on the manufacture and transfer process of the pitch will change, resulting in synchronous belt tooth and tooth in meshing season from the unequal, appear pitch error. A high pitch error, will make the transmission is not smooth, vibration and crawl phenomenon of tooth;
3．5起動頻繁而又有沖擊負(fù)荷時，導(dǎo)致帶齒從帶輪齒槽中跳出，也會產(chǎn)生爬齒
3.5 frequent starting and impact load, leading to Tooth jump from the belt pulley groove, also can produce climbing gear
3．6同步齒形帶應(yīng)用中一定要防止過載，否則也容易產(chǎn)生“爬齒”現(xiàn)象。
3.6 synchronous toothed belt applications to prevent overload, otherwise easily lead to "climb the tooth" phenomenon.
3．7有的企業(yè)使用了同步齒形帶，但是對于配套的張力輪的“張力”大小并不能很好掌握，要么拼命增大張力，要么張力不足。
3.7 some companies use the synchronous toothed belt, but for supporting the tension wheel "tension" is not very good master, either to increase tension, or the tension problem.
3．7．1張力輪過大的張力的危害：眾所周知，當(dāng)張力輪張力過大，加上張力輪軸剛度不足時，則會造成張力輪軸頭彎曲變形，從而發(fā)生跳動，這種跳動是有害的，它使得傳動變得不平穩(wěn)而產(chǎn)生高頻震蕩，從而產(chǎn)生高次諧波。
The harm of 3.7.1 tension wheel excessive tension: as everyone knows, when the tension wheel tension is too large, and the tension shaft stiffness is insufficient, will cause the bending deformation of the tension wheel shaft, then beat, the beat is harmful, it makes the transmission become unstable due to high frequency oscillation, resulting in higher harmonic.
3．7．2張力輪張力不足，則增加了齒形同步帶的”爬齒”現(xiàn)象帶來的不良情況。
3.7.2 lack of tension pulley tension, increased adverse situation caused climbing gear tooth synchronous belt "phenomenon".
同步齒形帶的“爬齒”現(xiàn)象對于紡織設(shè)備，如：并條機、梳棉機、粗紗機等，都是非常有害的。而“爬齒”現(xiàn)象就是產(chǎn)生機械波的重要原因之一！而且，這種“爬齒”現(xiàn)象往往具有無規(guī)律性的特點，因此常常還會產(chǎn)生較為復(fù)雜的“多重機械波”，這種“多重機械波”的產(chǎn)生，以及時有時無性，令難尋覓其蹤。增加了解決機械波的復(fù)雜性與難度！
The synchronous toothed belt "climbing gear" phenomenon for textile equipment, such as: drawing, carding, roving machine and so on, are very harmful. "Climbing gear" phenomenon is one of the important causes of mechanical wave! But, this kind of "climbing gear" phenomenon often has the characteristics of no regularity, and therefore often more complex "multiple mechanical wave", the "multiple mechanical wave", in a timely and sometimes asexual, make hard to find its trace. Increases the complexity and difficulty of solving mechanical wave!
4、解決齒形同步帶使用中的”爬齒”現(xiàn)象的對策措施
4, to solve the synchronous toothed belt in use "climbing gear" phenomenon Countermeasures
4．1要想保證傳動的準(zhǔn)確，對于制造廠，就必須提高同步帶齒制造精度確保節(jié)距與帶輪齒的節(jié)距相等。
4.1 to ensure the transmission accuracy, the manufacturing plant, we must improve the synchronous belt tooth manufacturing to ensure that the accuracy of pitch and tooth pitch.
4．2解決制造中的節(jié)距誤差和積累誤差‘
4.2 solve manufacturing pitch error and accumulated error '
4．3適當(dāng)?shù)念A(yù)加張力：同步帶傳動要有適當(dāng)?shù)膹埦o力。如FA317A型并條機產(chǎn)品說明書內(nèi)附有張力調(diào)整表便于了維修時的張力調(diào)整，并確保無因為張力不當(dāng)產(chǎn)生的機械波。
4.3 appropriate pre tension: synchronous belt transmission to a suitable tension. Products such as the FA317A type drawing machine instructions with tension adjustment table to adjust tension repair, and to ensure that no because of mechanical wave tension caused by improper.
4．4確保在使用中同步帶與齒
