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. Timing belt (camshaft) - Wikipedia

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

   Aside from the belt/chain itself, also common is a failure of the tensioner, and/or the various gear and idler bearings, causing the belt/chain to derail. Furthermore, in engines where the timing belt drives the water pump, failure of the water pump can cause the pump to seize, which can break the timing belt or chain.

   1888 Geared Facile Bicycle in the Coventry Transport Museum A chain-drive and rear gear hub A bicycle gearbox with chain tensioner A penny-farthing with direct-drive. A cyclist's legs produce power optimally within a narrow pedalling speed range. Gearing is optimized to use this narrow range as best as possible.

   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 ...

7. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   A belt drive is analogous to that of a chain drive; however, a belt sheave may be smooth (devoid of discrete interlocking members as would be found on a chain sprocket, spur gear, or timing belt) so that the mechanical advantage is approximately given by the ratio of the pitch diameter of the sheaves only, not fixed exactly by the ratio of ...
