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.

A belt-driven bicycle is a chainless bicycle that uses a flexible belt, typically a synchronous toothed design, in order to transmit power from the pedals to the ...
The twin-cylinder steam engine could be used either to drive the plough winch or to drive the vehicle along, at a speed of up to 150 cm/min (5 ft/min). Although the machine weighed 30 tons complete with 6 tons of fuel, its ground pressure was only 869 kg/m 2 (178 lb/sq ft), considerably less than a man.
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 ...
JVC (short for Japan Victor Company) is a Japanese brand owned by JVCKenwood.Founded in 1927 as the Victor Talking Machine Company of Japan and later as Victor Company of Japan, Ltd. (日本ビクター株式会社, Nihon Bikutā kabushiki gaisha), the company was best known for introducing Japan's first televisions and for developing the Video Home System video recorder.
Some drill presses and milling machines contain a simple belt-drive CVT system to control the speed of the spindle, including the Jet models J-A5816 and J-A5818. [50] In this system, the effective diameter of only the output shaft pulleys is continuously variable.
In a belt drive system, idlers are often used to alter the path of the belt, where a direct path would be impractical. Idler pulleys are also often used to press against the back of a pulley in order to increase the wrap angle (and thus contact area) of a belt against the working pulleys, increasing the force-transfer capacity.
Direct-drive systems are characterized by smooth torque transmission, and nearly-zero backlash. [9] [10] [11] The main [citation needed] benefits of a direct-drive system are increased efficiency (due to reduced power losses from the drivetrain components) and being a simpler design with fewer moving parts.
