This is one of the easiest and cheapest ways to transfer power in a machine. a) No-slip takes place in chain drive as in belt drive there is slip. Harley Davidson motorcycles use these, as do One of the most common devices, belt drives are used to transmit motion from one shaft to another with the help of a thin inextensible band that runs over two pulleys. Flat belts. Cross or twisted belt drives are used with rotating shafts in parallel and opposite directions. 11.1 (c), is mostly used in the factories and workshops, where a great amount of power is to be transmitted, from one pulley to another, when the two pulleys are more than 8 meters apart. Most belt drives consist of flat leather, rubber, or fabric belts running on cylindrical pulleys or of belts with a V-shaped cross section running on grooved pulleys.
