2. Capstan equation - Wikipedia

   en.wikipedia.org/wiki/Capstan_equation

   A flat belt has an effective angle of =. The material of a V-belt or multi-V serpentine belt tends to wedge into the mating groove in a pulley as the load increases, improving torque transmission. [6] For the same power transmission, a V-belt requires less tension than a flat belt, increasing bearing life. [5]

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. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft. A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.

5. Belt friction - Wikipedia

   en.wikipedia.org/wiki/Belt_friction

   Belt friction is a term describing the friction forces between a belt and a surface, such as a belt wrapped around a bollard.When a force applies a tension to one end of a belt or rope wrapped around a curved surface, the frictional force between the two surfaces increases with the amount of wrap about the curved surface, and only part of that force (or resultant belt tension) is transmitted ...

6. Variomatic - Wikipedia

   en.wikipedia.org/wiki/Variomatic

   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 or nearer the rim, depending on the separation of the cones. These are synchronized so that the belt always remains at the same optimal tension.

7. Preload (engineering) - Wikipedia

   en.wikipedia.org/wiki/Preload_(engineering)

   In the general sense, it refers to the internal application of stress to certain mechanical systems. By tensioning, preloading increases the natural frequency of a structure, avoiding resonance due to external disturbances. It also prevents buckling if stresses change depending on position in certain systems.

8. 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 ...

9. Continuously variable transmission - Wikipedia

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

   The V-belt runs between these two halves, so the effective diameter of the pulley is dependent on the distance between the two halves of the pulley. The V-shaped cross-section of the belt causes it to ride higher on one pulley and lower on the other; therefore, the gear ratio is adjusted by moving the two sheaves of one pulley closer together ...
