Working of Flywheel with the help of Turning moment diagram:
A flywheel used in machines serves as a reservoir, which stores energy during the period when the supply of energy is more than the requirement, and releases it during the period when the requirement of energy is more than the supply.
Advantages of V-belt drive over flat belt drive :
1. The V-belt drive gives compactness due to the small distance between the centres of pulleys.
2. The drive is positive, because the slip between the belt and the pulley groove is negligible.
3. Since the V-belts are made endless and there is no joint trouble, therefore the drive is smooth.
4. It provides longer life, 3 to 5 years.
5. It can be easily installed and removed.
6. The operation of the belt and pulley is quiet.
Centrifugal clutch is a clutch that uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft.
• A centrifugal clutch is a clutch that uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft.
• It consists of number of shoe on the inside of a rim of pulley. The outer surface of pulley is covered with friction material.
Effects of imbalance in machine
1. Imbalance imparts vibratory motion to the frame of the machine.
2. Produces noise which leads to human discomfort.
3. Detrimental effects on the machine performance & structural integrity of the machine foundation.
