TheSynchronous Belt drive is composed of an endless belt with equidistant teeth on the inner peripheral surface and a pulley with corresponding teeth. During operation, the synchronous belt teeth mesh with the tooth grooves of the pulley to transmit movement and power. Synchronous belt is a new type transmission belt with the advantages of belt transmission and chain transmission and gear transmission. Precautions for the installation and use of timing belts and timing wheels: Reduce the center distance of the pulleys. If there is a tension pulley, loosen it first, and then adjust the center distance after installing the belt. For transmission with a fixed center distance, remove the pulley first, install the belt on the pulley, and then install the pulley on the shaft to fix it.
