同步带梯状齿应力在轮齿位置，当小皮带轮直徑较钟头，PU同步带将使梯状齿同步带的齿型形变，危害与带传动齿轮的齿合，易造成噪音和震动，这针对速率较高的主传动系统而言是很不好的。因而，梯状齿同步带在数控车床尤其是数控加工的主传动系统中非常少应用，一般仅在转速比不太高的健身运动传动系统或小输出功率传动系统的驱动力传动系统中应用。
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.
具备很大的输出功率传送范畴，可以达到几瓦到几百千瓦同步带与皮带轮问有很大的节径差，
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：使带齿没法彻底进到轮齿槽，进而造成不彻底齿合情况，PU同步带生产厂家进而带齿在较小的触碰总面积上承担过大的荷载，进而造成应力，造成 带齿裁切毁坏。

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、带与皮带轮在围齿区域内的齿合齿数偏少，使齿合带齿承担过大的荷载，而造成裁切毁坏。
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、同步带的基材原材料抗压强度差。
3. The compressive strength of the base material of the synchronous belt is poor.
为降低带齿被裁切，Z先应严控带与皮带轮间的节径偏差，PU同步带厂家确保带齿与传动齿轮能恰当齿合；次之应使带与皮带轮在围齿区域内的齿合齿数相当于或超过
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，同步带除此之外在选料应该选用有较高勿切韧挤压成型抗压强度的原材料做为带的基材原材料。
4. In addition, raw materials with high shear toughness and extrusion compressive strength should be selected as the base material of the synchronous belt.
