Synchronous belt wheel transmission structure of the application as a equipment, need to be used for the transmission function of the product, is necessarily needed in can meet the requirements of transmission, can only be applied in the middle of the related equipment. Specifically, able to apply the pulley, will need to meet the following requirements: in terms of transmission transmission requires a: transmission accuracy. Once the synchronous belt wheel when applied to sliding, inevitably will directly affect the transmission device, which in turn makes the smooth operation of the equipment and even can't normal operation and use. From this perspective, pulley will need to conform to the requirements of the transmission accuracy this, can be used. Transmission requires 2: is stable. For any equipment need to be able to run smoothly, just can have stable function, presents the application effect of this equipment is very good. From this perspective, for the equipment used to play the transmission function of the synchronous belt wheel, you need to conform to the requirements of the transmission smooth this. Transmission requires three: high efficiency. Equipment at the time of application, you need to be able to have higher operation efficiency, to have high performance in work efficiency, so you need to play in the middle of the equipment transmission function of the synchronous belt wheel, to conform to the requirements of the high efficiency of the transmission.
