同步帶梯狀齒應(yīng)力在輪齒位置，當(dāng)小皮帶輪直徑較鐘頭，PU同步帶將使梯狀齒同步帶的齒型形變，危害與帶傳動齒輪的齒合，易造成噪音和震動，這針對速率較高的主傳動系統(tǒng)而言是很不好的。因而，梯狀齒同步帶在數(shù)控車床尤其是數(shù)控加工的主傳動系統(tǒng)中非常少應(yīng)用，一般僅在轉(zhuǎn)速比不太高的健身運動傳動系統(tǒng)或小輸出功率傳動系統(tǒng)的驅(qū)動力傳動系統(tǒng)中應(yīng)用。
The ladder tooth stress of the synchronous belt is at the tooth position. When the diameter of the small pulley is small, the Pu synchronous belt will deform the tooth profile of the ladder tooth synchronous belt, endanger the meshing with the belt transmission gear, and easily cause noise and vibration, which is very bad for the main transmission system with high speed. Therefore, the ladder tooth synchronous belt is rarely used in the main transmission system of NC lathe, especially NC machining center. Generally, it is only used in the driving force transmission system of fitness transmission system or low output power transmission system with low speed ratio.
具備很大的輸出功率傳送范疇，可以達到幾瓦到幾百千瓦同步帶與皮帶輪問有很大的節(jié)徑差，
It has a large output power transmission range, which can reach several watts to hundreds of kilowatts, and there is a large pitch diameter difference between the synchronous belt and the belt pulley,
1：使帶齒沒法徹底進到輪齒槽，進而造成不徹底齒合情況，PU同步帶生產(chǎn)廠家進而帶齒在較小的觸碰總面積上承擔(dān)過大的荷載，進而造成應(yīng)力，造成 帶齒裁切毀壞。

1: The belt teeth can not completely enter the tooth groove, resulting in incomplete meshing. The Pu synchronous belt manufacturer bears too much load on the small total contact area, resulting in stress and cutting damage of the belt teeth.
2、帶與皮帶輪在圍齒區(qū)域內(nèi)的齒合齒數(shù)偏少，使齒合帶齒承擔(dān)過大的荷載，而造成裁切毀壞。
2. The number of meshing teeth of belt and pulley in the surrounding tooth area is too small, which makes the meshing belt teeth bear too much load and cause cutting damage.
3、同步帶的基材原材料抗壓強度差。
3. The compressive strength of the base material of the synchronous belt is poor.
為降低帶齒被裁切，Z先應(yīng)嚴控帶與皮帶輪間的節(jié)徑偏差，PU同步帶廠家確保帶齒與傳動齒輪能恰當(dāng)齒合；次之應(yīng)使帶與皮帶輪在圍齒區(qū)域內(nèi)的齒合齒數(shù)相當(dāng)于或超過
In order to reduce the cutting of belt teeth, Z shall strictly control the pitch diameter deviation between the belt and the pulley, and the Pu synchronous belt manufacturer shall ensure that the belt teeth and the transmission gear can be properly meshed; Secondly, the number of meshing teeth of the belt and pulley in the girth area shall be equal to or more than
4，同步帶除此之外在選料應(yīng)該選用有較高勿切韌擠壓成型抗壓強度的原材料做為帶的基材原材料。
4. In addition, raw materials with high shear toughness and extrusion compressive strength should be selected as the base material of the synchronous belt.
