A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is usually a flexible belt with tooth moulded onto its inner surface. It is designed to run over coordinating toothed pulleys or sprockets . Toothed belts are found in a wide array of in mechanical devices, where high-power transmission is desired.
Toothed belts are utilized widely in mechanical devices, which includes sewing machines ,photocopiers and many more. A major use of toothed belts is really as the timing belt used to operate a vehicle the camshafts within an car or motorcycle engine.
As toothed belts can deliver more power than a friction-drive belt, they are utilized for high-power transmissions. These include the primary get 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 usage of a quieter and more efficient slower-quickness propeller. Some amateur-built airplanes driven by automotive engines make use of cog belt reduction drive units.
A tooth pulley has some teeth whereas a set belt pulley does not have any teeth.

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