斜齿正时皮带传动的噪音和寿命

Noise and Life of Helical Timing Belt Drives

正时皮带被使用，因为他们花费少于链子，而且噪音少。

Timing belts are used because they cost less than chains and operate more quietly .

A typical timing belt is made of neoprene ( synthetic rubber ) reinforced with fiberglass .

更换正时皮带的花费不便宜，但是和一直不更换的代价比较就要小多了。

Timing belt replacement is not a cheap job but it is far less costly than the alternative .

顶制凸轮轴结构的汽车发动机都配备了正时皮带，并且这个皮带的生命周期是有限的.双凸凸轮正弦加速度机构在金属筒体印花设备上的应用

Certain engines with overhead camshafts have timing belts that have a limited life span . Application of Biconvex Cam Sine Acceleration Framework in Metallic Roller Printing Equipment

正时皮带的工作是：当保持精准定位时调整凸轮轴的运转速度为曲轴速度的一半。

The job of the timing belt is to turn the camshaft ( s ) at exactly 1 / 2 the speed of the crankshaft while maintaining a precise alignment .

把这些正时皮带的噪音和寿命与斜角为0°的常规正时皮带进行了比较。

The noise and life of the helical timing belt under a constant transmission force are compared with those of a conventional timing belt , in which the helix angle is zero .

一种新的降低噪音的斜齿正时皮带已经被开发，本研究采用一种曲线齿廓分别设计了斜角为3°、5°和10°的三种皮带。

A new helical timing belt has been developed to reduce noise . In the present study , three belts , each having a curvilinear tooth profile and helix angles of 3 deg , 5 deg and 10 deg , respectively , were designed .
