The design of the synchronous belt wheel was more accurate, and it will also supply for the transmission of accurate proportion, in the actual transmission of lubrication is poorer, but the speed is more able to maintain, and have the function of a constant, and also absorb the vibration, noise is small, the transmission is relatively stable, and the efficiency is relatively high, another is synchronous belt wheel is a kind of no pollution components, even where the environment is bad also can be normal operation, will not affect the work process. Purpose: high efficiency synchronous belt wheel can be normal where the environment is bad, it is very rare a purpose, and it also can provide a relatively now even more efficient transmission power output and synchronous belt wheel in many areas are quite widely applied, its overall is very popular and attention. Anything at the time of first bought these abnormal conditions are not available, because it is new, the advantages of the synchronous belt wheel and the quality of the products are guaranteed, so just buy back in time can be at ease of use, but in the use of a period of time after or want to be a good maintenance, it is quite critical. Through such processing and better maintenance and maintenance, the effect of synchronous belt wheel and the quality will be better.
