2. Serpentine belt - Wikipedia

   en.wikipedia.org/wiki/Serpentine_belt

   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 ...

3. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   The belt also tends to wedge into the groove as the load increases—the greater the load, the greater the wedging action—improving torque transmission and making the V-belt an effective solution, needing less width and tension than flat belts. V-belts trump flat belts with their small center distances and high reduction ratios.

4. Timing belt (camshaft) - Wikipedia

   en.wikipedia.org/wiki/Timing_belt_(camshaft)

   A timing belt is typically made from rubber, although some belts are instead made from polyurethane or neoprene. [8] [9] The structure of the belt is reinforced with corded fibres (acting as tension members) [10] and the toothed surface is reinforced with a fabric covering. [11] Rubber degrades with higher temperatures, and with contact with ...

5. Toothed belt - Wikipedia

   en.wikipedia.org/wiki/Toothed_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 ...

6. Continuously variable transmission - Wikipedia

   en.wikipedia.org/wiki/Continuously_variable...

   Simple CVTs combining a centrifugal drive pulley with a spring-loaded driven pulley often use belt tension to effect the conforming adjustments in the driven pulley. [3] The V-belt needs to be very stiff in the pulley's axial direction to make only short radial movements while sliding in and out of the pulleys.

7. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   With belts and pulleys, friction is one of the most important forces. Some uses for belts and pulleys involve peculiar angles (leading to bad belt tracking and possibly slipping the belt off the pulley) or low belt-tension environments, causing unnecessary slippage of the belt and hence extra wear to the belt.

8. Composite bearing - Wikipedia

   en.wikipedia.org/wiki/Composite_bearing

   There is a spring device in the belt tensioner where the bearing is located. The spring device oscillates back and forth at 2° for about 60 cycles per minute. Composite bearings ensure an appropriate and consistent level of torque and damping to maintain the correct tension in the drive belt while the engine is in operation.

9. Variomatic - Wikipedia

   en.wikipedia.org/wiki/Variomatic

   Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne. [1] It is a stepless, fully- automatic transmission , consisting of a V-shaped drive-belt, and two pulleys , each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle ...
