What is a common cause for a V belt to slip or squeak during operation?

A V belt slipping or squeaking during operation is commonly caused by insufficient tension. When the V belt is not adequately tensioned, it cannot effectively transfer power from the drive pulley to the driven pulley. This lack of tension leads to a loss of grip on the pulley surfaces, causing the belt to slip. The squeaking sound often accompanies the slipping, as the belt may rub against the pulleys in a way that generates friction and noise.

Ensuring that the V belt is properly tensioned is crucial for optimal performance and longevity. Proper maintenance includes regular checks of the belt's tension and condition, as well as adjusting it as needed to maintain the right amount of tension. This proactive management helps prevent slipping and the associated noise, leading to more efficient operation of the machinery involved.
