24/08/2015  The belts and ropes are flexible members which are used where distance between the two shafts is large. The chains also have flexibility but they are preferred for intermediate distances. The gears are used when the shafts are very close with each other. This type of drive is also called positive drive because there is no slip. If the distance is slightly larger, chain drive can be used for ...

Mechanical elements like friction disc, various types of belts, rope, chain, gears, couplings, etc. are used for power transmission. BELT DRIVE : To transmit power from one shaft to another, pulleys are mounted on the two shafts. The pulleys are then connected by an endless belt passing over the pulleys. The connecting belt is kept in tension so that motion of one pulley is transferred to the ...

Belts, chains and gears are used for this purpose. When the distance between the shafts is large, belts or ropes are used and for intermediate distance chains can be used. For belt drive distance can be maximum but this should not be more than ten metres for good results. Gear drive is used for short distances. 3.2.1 Belts In case of belts, friction between the belt and pulley is used to ...

As the name suggests, chain drives come with an endless series of chain links with a net of toothed sprockets. Unlike belt drives, there is no slip in chain technology. However, they are mostly suited for small centre distances, usually up to 3 metre. In some special circumstances, chain drives can even cover a distance of up to 8 meter.

Belt (mechanical) - Wikipedia

V belts (also style V-belts, vee belts, or, less commonly, wedge rope) solved the slippage and alignment problem. It is now the basic belt for power transmission. They provide the best combination of traction, speed of movement, load of the bearings, and long service life. They are generally endless, and their general cross-section shape is roughly
