Explanation:

Belt Drive

  • The belt drive is the most common method of power transmission.
  • The belts are made from leather, cotton, rubber, and synthetic materials.


There are four types of belts:

  1. Flat belt
  2. V - belt and multiple V - belt
  3. Ribbed belt
  4. Toothed or timing belt


V - Belt drive

  • V - belt drives are generally used when the distance between the shafts is short for flat belt drives.
  • Owing to the wedge action between the belt and the sides of the groove in the pulley, the V belt is less likely to slip, hence more power can be transmitted.


Advantages of V -belt drive

  • It is compact, so installation is possible in limited space
  • It is used when the center distance between the drive and the driven pulleys is short.
  • Less vibration and noise
  • Cushions the motor and bearings against load fluctuation
  • Easy replacement and maintenance
