A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is usually a flexible belt with teeth moulded onto its internal surface. It is made to run over complementing toothed pulleys or sprockets . Toothed belts are used in a wide array of in mechanical devices, where high-power tranny is desired.
Toothed belts are used widely in mechanical devices, including sewing machines ,photocopiers and many others. A major use of toothed belts is as the timing belt utilized to operate a vehicle the camshafts within an car or motorcycle engine.
As toothed belts may deliver more power than a friction-travel belt, they are used for high-power transmissions. Included in these are the primary drive of some motorcycles , notably later on Harley-Davidsons ;and the supercharger used for dragsters .
Microlight aircraft driven by high-speed two-stroke engines such as the Rotax 532 use toothed belt reduction drives to allow the utilization of a quieter and more efficient slower-speed propeller. Some amateur-built airplanes powered by automotive engines make use of cog belt decrease drive units.
A good tooth pulley has some the teeth whereas a flat belt pulley doesn’t have any teeth.

The tooth pulley is utilized when accurate transmission of the torque is necessary. Flat belt pulleys or V-belt pulleys cannot deliver 100% accurate transmitting of the torque because almost always there is some (hardly any – but nonetheless) slipping between your pulley and belt.
