Synchronous belt wheel is composed of two parts, one is the belt, the other one is the synchronous wheel. Used in machinery , the combination of synchronous belt wheel and belt is necessary, only when the timing belt or belt wheel used together ,can play its due role, the single is of no use.
Although synchronous belt wheel is a combination of synchronous belt wheel and belt , but synchronous belt wheel should correspond to one of the gullet needs, it is not so simple. If not calculate well, it will cause deviation. So during the manufacture and installation are particularly important,especially in production ,the size must correspond to the class, the corresponding pitch, tooth height, with thick, etc. shall be measured to produce precise. Step in the installation is also very important, when to synchronize round tops belt, do not overexert or with a screwdriver to pry the belt hard, otherwise it will break, and if the center from two synchronized wheels can move, it must first center distance is shortened, when installed belt, and then make the center distance reset.
