For a friend to ask a while ago, his new purchase of synchronous belt only be damaged more than a month, wonder if there is something wrong with the quality of synchronous belt. For this problem, also not once met, in fact many consumers like him, when encountered some products out of the question, diyi reaction is whether there is something wrong with the quality. Actually for synchronous belt early damage might be caused by a variety of combination, when this kind of situation, we should according to this article damage possibility to screening, thus to solve it, and do not blindly pursue is the responsibility of the merchant. Early damage a synchronous belt: 1) improper installation Synchronous belt is the improper installation of a common phenomenon, use brute force, when installation directly with a hammer percussion synchronous belt wheel of synchronous belt wheel damage zui, also is the main cause of deformation. 2) Installation does not reach the designated position, deviation or not installed to the axle hole, synchronous belt wheel clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart, over time lead to damage of synchronous belt, the wheels. Synchronous belt early damage 2: pollution pollution can also cause synchronous belt, round of premature failure, in this case, the pollution is with dust and metal scraps into the synchronous belt and synchronous belt tooth position. Main causes include: disorderly piled up before use, pollution, or the installation work environment is not clean, cause pollution and work environment of the synchronous belt is clean, working medium pollution, etc. Synchronous belt early damage 3: fatigue fatigue failure is a common way of damaged zui synchronous belt, round, and this phenomenon can lead to the risk of early damage of the synchronous belt is very big, the cause of the common fatigue failure may be: synchronous belt long-term overload operation, failed to timely maintenance, improper maintenance, equipment aging, etc.
