Run two to three years after the timing belt do not need to take any remedial measures. Timing belt life due to the application of different and various objective factors, there are significant changes. Factors affecting the timing belt life, including the tran***ission power level, the environment, timing belt installation tension with with round match, the quality level of the pulley, or even how to cut in two to three years after the timing belt operation, when its core lines of fatigue In life, timing belt failure is a normal situation. After a long operation, the timing belt due to the wire to reach the fatigue life and failure, which belongs to the ideal timing belt failure mode. Figure 1 is a mixed 45-degree angle jagged fracture belt, which is typical timing belt wire to reach the normal fatigue life.
Synchronous belt tooth will also fail, but this is not the ideal timing belt failure mode. In the long-term operation, although the timing belt is able to maintain the size and shape of the initial, but the timing belt tooth wear appear. Exposed fiber makes timing belt timing belt canvas tooth looks rough and frizzy.
BRECO同步带同步带的正常磨损和失效
运行二到三年后的同步带不需要再采取任何改善措施。同步带寿命会由于应用的不同，以及各种客观因素而有较大变化。影响同步带寿命的因素包括传输功率等级，环境，同步带安装张力，带与轮的匹配，带轮的质量水平，甚至是如何切
在同步带运转二到三年后，当其芯线达到疲劳寿命时，同步带失效是属于正常情况。在经过长期运转后，同步带由于芯线达到疲劳寿命而失效，这属于理想的同步带失效模式。图1 是一个参差不齐的45 度角的锯齿状断裂同步带，这是典型的同步带芯线达到正常的疲劳寿命造成的。
pulleys beating lead to timing belt failure
Timing belt pulleys to wear a cone installed, or installed after re-reaming, often prone to beating the ***allest pulley light-hole basis. How to install in accordance with the standa***, and how to ensure the shaft hole with understanding or c***ultation timing belt runs in a pulley system runout when the timing belt, timing belt pulleys rotating in the belt technical documentation of inspection Weixin Zhang tight power of the cyclical rise and fall. Beating the more powerful, higher maximum tension on the rise. Affected, so that the bottom teeth look like to be crushed, as shown below. Crushed with the possible is similar to the phenomenon of running in the moderate size pulley belt tension is too high. Extreme cyclical changes in tension timing belt teeth often result in tearing or timing belt tensile fracture.
BRECO同步带同步带轮跳动导致同步带失效
同步带轮往锥套上安装，或在***小的带轮光孔基础上进行再扩孔后安装时，往往容易发生跳动。如何按照标准进行安装，以及如何确保轴孔的配合，在查阅韦欣同步带技术文档进行相关了解或者咨询同步带运行在径向跳动的带轮系统中时，同步带轮旋转时BRECO同步带的张紧力会周期性的升降。跳动的越厉害，***大张紧力就升的越高。受此影响，使齿底看起来像被碾碎一样，如下图。碾碎的带体可能与在适度尺寸带轮中而运行的同步带张紧力过高所导致的现象相类似。而极端周期性的张力变化常常导致同步带齿部撕裂或同步带拉伸性断裂。
