Timing belt drive consists of an endless belt whose inner surface has equal spaced teeth and belt pulley which have the relative teeth. While working, the teeth of the belt and the teeth of the pulley joggle each other to transmit the motion and the dynamic force. It is a kind of new type drive which has synthesized all the good points of belt drive, chain drive and gear drive. Timing belt drive has such features as: ·Exact transmission ratio, no sliding. ·Larger transmission ratio scope which may normally reach to 1:10, allowable linear speed may reach to 40m/s. ·High transmission efficiency which may normally reach to 98%-99%. ·Constant velocity ratio, smooth motion, little noise. ·Compacting structure, suitable to multi-axis transmission, no need lubrication, no pollution. Now we have over 30 types timing belt with more than 3000 specifications, and we can supply related pulleys. It may also design and manufacture timing belt with special specification to satisfy customer’s requirements.
* Chloroprene body provides protection against oil, grease, heat and aging.
* Glass Fiber cords provides high strength, good flexing performance, and low elongation.
* Nylon fabric tooth facing provides resistance to abrasion and tooth shear.
The double-sided pitch synchronous belt and tooth profile equivalent to a single tooth and tooth belt pitch. Double teeth with tooth by the synchronous belt arrangement standards can be divided into two types; DA-duplex synchronous belt tooth, a tooth with its two symmetrical arrangement, see Figure (a) DB-duplex synchronous belt gear, with its two locations with staggered teeth were, see Figure (b)
