Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...
The open belt drive has parallel shafts rotating in the same direction, whereas the cross-belt drive also bears parallel shafts but rotate in opposite direction. The former is far more common, and the latter not appropriate for timing and standard V-belts unless there is a twist between each pulley so that the pulleys only contact the same belt ...
Supercharger drive belt in a dragster. A toothed belt, timing belt, cogged belt, cog belt, or synchronous belt is a flexible belt with teeth moulded onto its inner surface. Toothed belts are usually designed to run over matching toothed pulleys or sprockets. Toothed belts are used in a wide array of mechanical devices where high power ...
The capstan equation [1] or belt friction equation, also known as Euler–Eytelwein formula [2] (after Leonhard Euler and Johann Albert Eytelwein), [3] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan).
Rope drive in a hydroelectric plant Multiple rope drives driving lineshafts on each factory floor. The rope drives were placed in a large diagonal shaft at the side of the building, usually windowless and distinctively visible from outside the building. [ii] Rope drives required a larger such shaft than comparable belt or shaft drives.
A drive shaft connecting a rear differential to a rear wheel may be called a half-shaft. The name derives from the fact that two such shafts are required to form one rear axle. Early automobiles often used chain drive or belt drive mechanisms rather than a drive shaft. Some used electrical generators and motors to transmit power to the wheels.

The functional relationship between the drive belt, sub-platter, and motor pulley, can be seen through the glass platter on a Rega Planar 3.. There are three main types of phonograph turntable drives being manufactured today: the belt-drive, idler-wheel and direct-drive systems; the names are based upon the type of coupling used between the platter of the turntable and the motor.
