Question: 1 / 400

What additional adjustment can increase the efficiency of a V-belt drive?

Adjusting pulley size

Changing belt material

Tensioning the belt properly

Tensioning the belt properly is crucial in increasing the efficiency of a V-belt drive. When a belt is properly tensioned, it maintains optimal contact with the pulleys, reducing slippage and ensuring effective transfer of power. Under-tensioned belts can lead to excessive wear and ultimately decrease the system’s efficiency. Conversely, if the belt is over-tensioned, it may increase wear on the bearings and cause premature failure. Therefore, achieving the right tension is key to optimizing performance and efficiency in the drive system.
