2. Tensioner - Wikipedia

   en.wikipedia.org/wiki/Tensioner

   Chain tensioner on a single-speed bicycle Belt tensioner on a belt-drive bicycle Hydraulic bolt tensioner Hydraulic Puller-tensioner . A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring ...

3. Serpentine belt - Wikipedia

   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 ...

4. 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.

5. 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.

7. Idler-wheel - Wikipedia

   en.wikipedia.org/wiki/Idler-wheel

   Belt drive systems commonly incorporate one movable pulley which is spring- or gravity-loaded to act as a belt tensioner, to accommodate stretching of the belt due to temperature or wear. An idler wheel is usually used for this purpose, in order to avoid having to move the power-transfer shafts.
