rubber timing belt Synchronous belt drives consistes of an endless belt whose inner surface has equally spaced teeth and of wheels which have the corresponding teeth and is a kind of new type belt drive which has synthesized all the good points of belt drive, chain drive and gear drive while working, the teeth of the belt and the gullets of the gear joggle each other to transmit the motion and the dynamic force. Synchronous belt drive has such features as exact transmission ratio, non-sliding, constant velocity ratio which can be gained, even motion, absorption of vibration, little noise, the big range of transmission ratio which can normally reach 0.98, compacting struture, the suitability to multi-axis transmission, no need of lubrication, pollution and so on. Therefore, the product can normally work well in the places where no pollution is allowed and where the working condition is poor and can widely be used in machinery drives, such industry as automobiles, machine tools textile, chemical engineering, light industry, mining, instruments, oil industry and so on, as well as all kinds of other machinery drive.
