In the belt running from 2 to 3 years later, when the core wire to fatigue life, belt failure is belong to the normal situation. After a long operation, belt due to core line to the fatigue life and failure, Special timing belt which belongs to the ideal belt failure mode. Figure 1 is an uneven 45 degree angle serrated fracture belt, which is typical of the belt core reach normal fatigue life caused by.
Synchronous belt teeth can also be a failure, but it does not belong to the ideal belt failure mode. In the long run, although the belt to maintain the original size and shape, but the belt teeth will wear. Belt canvas exposed fiber will make the belt tooth looks rough hair dry, as shown in figure 2.
Run 2 to 3 years after the belt do not need to take any measures to improve. Belt life due to different applications, Automotive Timing Belt as well as various objective factors and have bigger change. Influence of belt life factors include the transmission power level, the environment, the belt tension, belt and belt wheel round of match, the level of quality, or even how cutting, packaging, transportation and installation of belt.
