The power is transmitted from one shaft to the other by means of belts, ropes, chains, and gears.
- The belts and ropes are flexible members which are used where the 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 to each other.
- A chain drive is also called a positive drive because there is no slip.
- If the distance is slightly larger, a chain drive can be used for making it a positive drive.
- Belts and ropes transmit power due to the friction between the belt or rope and the pulley.
- There is a possibility of slip and creep in belts and rope drive and that is why this drive is not a positive drive.
Hence, due to no-slip condition, the chain drive has a maximum efficiency of power transmission.
