A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is definitely a versatile belt with teeth moulded onto its internal surface. It is designed to run over complementing toothed pulleys or sprockets . Toothed belts are used in several in mechanical devices, where high-power transmission is desired.
Toothed belts are used widely in mechanical products, including sewing machines ,photocopiers and many more. A major use of toothed belts is really as the timing belt utilized to operate a vehicle the camshafts in a automobile or motorcycle engine.
As toothed belts can deliver more power when compared to a friction-travel belt, they are utilized for high-power transmissions. These include the primary drive of some motorcycles , notably afterwards Harley-Davidsons ;and the supercharger used for dragsters .
Microlight aircraft driven by high-speed two-stroke engines like the Rotax 532 use toothed belt reduction drives to allow the use of a quieter and better slower-acceleration propeller. Some amateur-built airplanes run by automotive engines use cog belt reduction drive units.
A tooth pulley has some tooth whereas a flat belt pulley doesn’t have any teeth.

The tooth pulley can be used when accurate transmission of the torque is necessary. Smooth belt pulleys or V-belt pulleys cannot deliver 100% accurate transmitting of the torque because there’s always some (very little – but nonetheless) slipping between your pulley and belt.
