A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is a versatile belt with the teeth moulded onto its inner surface. It is made to run over complementing toothed pulleys or sprockets . Toothed belts are used in several in mechanical products, where high-power transmitting is desired.
Toothed belts are used widely in mechanical products, including sewing machines ,photocopiers and many others. A major use of toothed belts is as the timing belt used to operate a vehicle the camshafts within an car or motorcycle engine.
As toothed belts may deliver more power when compared to a friction-get belt, they are used for high-power transmissions. These include the primary get 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 better slower-level propeller. Some amateur-built airplanes run by automotive engines make use of cog belt reduction drive units.
A good tooth pulley has some tooth whereas a flat belt pulley doesn’t have any teeth.
The tooth pulley is used when accurate transmission of the torque is needed. Flat 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.
