2. Toothed belt - Wikipedia

   en.wikipedia.org/wiki/Toothed_belt

   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 transmission is desired.

3. Belt (mechanical) - Wikipedia

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

   A drawback to belt drives is that they transmit less power than gears or chain drives. However, improvements in belt engineering allow use of belts in systems that formerly only allowed chain drives or gears. Power transmitted between a belt and a pulley is expressed as the product of difference of tension and belt velocity:

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. Timing belt (camshaft) - Wikipedia

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

   3] A toothed rubber timing belt, also known as a synchronous belt, is a crucial component in an internal combustion engine. It is made of durable rubber and features teeth on its inner surface that mesh with corresponding grooves on the crankshaft and camshaft pulleys.

6. Gear train - Wikipedia

   en.wikipedia.org/wiki/Gear_train

   Bicycle with toothed belt drive to transmit torque from crank to rear sprocket. Special gears called sprockets can be coupled together with chains, as on bicycles and some motorcycles. Alternatively, belts can have teeth in them also and be coupled to gear-like pulleys. Again, exact accounting of teeth and revolutions can be applied with these ...

7. Mechanical advantage - Wikipedia

   en.wikipedia.org/wiki/Mechanical_advantage

   For a toothed belt drive, the number of teeth on the sprocket can be used. For friction belt drives the pitch radius of the input and output pulleys must be used. The mechanical advantage of a pair of a chain drive or toothed belt drive with an input sprocket with N A teeth and the output sprocket has N B teeth is given by

8. Belt-driven bicycle - Wikipedia

   en.wikipedia.org/wiki/Belt-driven_bicycle

   Gates bike belt drive system Belt-drive Belt-drive single-speed rear hub on a Trek District Belt-drive crankset on a Trek District Belt-drive multi-speed rear hub gear on a Trek Soho. 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 ...

9. Conveyor pulley - Wikipedia

   en.wikipedia.org/wiki/Conveyor_pulley

   A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt.Modern pulleys are made of rolled shells with flexible end disks and locking assemblies.
