Analysis and Solution of the Slippage Problem of a Gasoline Engine Damping Pulley
The vibration damping pulley assembly is a functional part of the engine.Its failure affects the power and NVH performance of the engine.During the development of a certain engine,the relative slip-page between the pulley and the hub of the damping pulley occurred.After the cause analysis and test ver-ification,it was found that the structure of the pulley structure,the rubber material and the assembly pro-cess all affect the slip torque of the damping pulley.Aiming at the cause of the relative slip of the vibra-tion damping pulley,corrective measures are proposed and verified.
