Synchronous belt drive consists of an endless belt whose Inner surface has equally soaced teeth and of belt wheels which have the corresponding teeh and is a kind of new type belt drive which has synhesized all the good points og belt drive, chain drive and gear drive, while working, the teeth o 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-sllding, constant velocity ratio which can be gained, even motion, absorption ofvibration, little noise,the bia range of transission ratio which can normaly reach 0.98, compacting tructure.The suitability to multi-axis transmission,no need of lubrication,no pollution and so on. Therefore,the product can notmally 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 automebiies, machine tools, textile, chemical engineering, light industry, mining,indtruments, oil industry and so on as well as all kinds of other machinery drive.
Synchronous belt we produced have a lot of advantages:anti-wearing out, low elongation rate and high strength, resistant to wide temperature range, non-aging, ozone resistant,etc. now we have over 30 types timing belt with more than 2000 specification.And we can supply matched pulleys. All these can meet our customers perfectly . The property of our products have reached or surpassed the internaional standard.
