A good toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is certainly a versatile belt with teeth moulded onto its internal surface. It is made to run over complementing toothed pulleys or sprockets . Toothed belts are used in several in mechanical gadgets, where high-power tranny is desired.
Toothed belts are used widely in mechanical gadgets, including sewing machines ,photocopiers and many more. A major usage of toothed belts is as the timing belt utilized to operate a vehicle the camshafts in a automobile or motorcycle engine.
As toothed belts may deliver more power when compared to a friction-get belt, they are used for high-power transmissions. Included in these are the primary travel of some motorcycles , notably afterwards 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 use of a quieter and better slower-fee propeller. Some amateur-built airplanes run by automotive engines use cog belt decrease drive units.
A good tooth pulley has some tooth whereas a flat belt pulley does not have any teeth.
The tooth pulley can be used when accurate transmission of the torque is needed. Toned belt pulleys or V-belt pulleys cannot deliver 100% accurate transmission of the torque because there’s always some (very little – but still) slipping between your pulley and belt.
