What Causes Belt Squealing?
1 Answers
Because the belt slips on the generator, intense friction and vibration occur between the belt and the pulley, producing a noise at a certain frequency. The main reasons for belt slippage are belt looseness or aging. Factors that can cause belt looseness include improper adjustment of the belt tensioner or insufficient tensioner spring force. Below is extended information about the belt: 1. Solution: Adjust the tension of the belt tensioner; if ineffective, replace the tensioner. Belt aging mainly refers to the belt gradually hardening and losing elasticity over prolonged use, reducing friction with the pulley. In this case, the only solution is to replace the belt. 2. Adjustment: If the belt is too loose, it will slip and produce noise; if too tight, it increases the belt's transmission resistance and causes premature wear on the bearings of the driven generator, water pump, and air conditioning. Adjusting the generator belt to the proper tension is crucial.
