A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is usually a versatile belt with teeth moulded onto its internal surface. It really is designed to run over complementing toothed pulleys or sprockets . Toothed belts are found in several in mechanical devices, where high-power transmitting is desired.
Toothed belts are utilized widely in mechanical gadgets, including sewing machines ,photocopiers and many more. A major utilization of toothed belts is really as the timing belt used to drive the camshafts within an car or motorcycle engine.
As toothed belts may deliver more power when compared to a friction-drive belt, they are used for high-power transmissions. These include the principal 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 decrease drives to allow the use of a quieter and more efficient slower-acceleration propeller. Some amateur-built airplanes run by automotive engines use cog belt decrease drive units.
A tooth pulley has some teeth whereas a flat belt pulley doesn’t have any teeth.

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