Believe used pulley users know, some of the synchronous belt and synchronous belt wheel with long time, some use time is short, many users simply think that just the quality problem of the pulley and synchronous belt, actually, not only because of the quality. In the process of using and see there are not too big exception, as well as the noise is too big, too much shaking of performance, if you have these performance, should immediately stop using, check the corresponding parts. Due to the synchronous belt wheel belongs to a partial door machine, many consumers also issuing poorly understood to its use. Company through many years of experience on the use of synchronous belt wheel to make the following analysis. Before using pulleys must first to check, look inside the machine whether have impurities, and clean up, add some lubricating oil. After the product processing, if appear synchronous belt wheel wear, has replaced immediately synchronous belt. In use process, think error can cause synchronous belt wheel noises, it is to stop using immediately. Check whether any blocked in the machine, as well as product placement is correct. Check whether the synchronous belt wheel in a straight line is symmetrical, wheeled into linear symmetry in belt especially the synchronous belt transmission device operation is very important. These are the use of synchronous belt and synchronous wheel should pay attention to when using.
