Although the synchronous belt appeared in our country and the use of time is not long, but with the improvement of industrial development speed, people should be very familiar with, of them should know it is one of the important components of machinery and equipment, is to ensure its effective implementation of transmission function. In order to ensure that the use of the synchronous belt is normal, for will affect its performance factors to understand people, and also should take corresponding measures to prevent. Quality factors: people at the time of purchase of synchronous belt for quality problem is definitely can not ignore, if choose inferior product, so its in use process will very likely lead to the emergence of fault for quality closes nevertheless, it is necessarily will affect its performance. Use: for use of the synchronous belt, who should take the correct measures, or incorrect use is easily lead to the occurrence of fault, it is also can affect the performance of the play, suggests that people can understand the specific operation method, before use and use should be carried out strictly in accordance with the requirements. Although the use of the synchronous belt is because of the existence of some factors resulting in a loss of performance, but the people should pay more attention to in practical use, only need according to the reason to carry on the corresponding prevention, can ensure that the performance of the play.
