Does a Noisy Tensioner Pulley Damage the Car?
1 Answers
A noisy tensioner pulley can indeed damage the car. If the tensioner pulley makes abnormal noises and is not replaced promptly, it may affect driving safety over time, causing engine vibration, difficulty in ignition, and in severe cases, failure to start the car. After starting, it may even deform the valves. Therefore, it should be replaced as soon as possible. Below is some relevant information about the tensioner pulley: 1. Belt Tensioning Device: The tensioner pulley is a belt tensioning device used in the automotive transmission system. It mainly consists of a fixed housing, tensioning arm, pulley body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the belt's tightness, ensuring the transmission system's stability, safety, and reliability. 2. Requires a Certain Torque: During actual use, the tensioner pulley requires a certain torque to maintain proper belt tension, prevent belt slippage, and compensate for elongation caused by belt wear and aging. When the tensioner pulley operates, the moving belt may excite vibrations in the pulley, leading to premature wear of both the belt and the pulley. To address this, a resistance mechanism is added to the tensioner pulley. However, since many parameters affect the pulley's torque and resistance, and their impacts vary, the relationship between the pulley's components and torque/resistance is highly complex. Torque changes directly affect resistance changes and are the primary influencing factor. The main factor affecting torque is the torsion spring's parameters. Appropriately reducing the torsion spring's mean diameter can increase the pulley's resistance value. 3. Function of the Tensioner Pulley: It is used to adjust the tightness of the timing belt and is usually replaced along with the timing belt to avoid future issues. Other parts do not need replacement unless necessary, and regular maintenance is sufficient.
