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

The tooth pulley is used when accurate transmission of the torque is necessary. Toned belt pulleys or V-belt pulleys cannot deliver 100% accurate tranny of the torque because almost always there is some (hardly any – but still) slipping between the pulley and belt.
