Summary:

Studies of belt tooth breakage have usually been carried out in motoring tests which focused on the load applied on the driven flank of the belt teeth. These studies have generally been done within the context of investigations into timing belt failure. There have been few studies of belt breakage in an internal combustion engine. In this investigation detailed analyses, based on firing test data and the finite element method, were made of belt cord stress. It was found that the main reason for belt breakage was belt cord stress caused by interference between the belt teeth and the pulley teeth due to torque fluctuations. A special device was developed for measuring the maximum cord surface strain during firing when the belt begins to engage with the driven flank belt teeth. Maximum strain was found to be five to ten times larger than the effective tension. Calculations were also made of the belt dimensions for optimum meshing between the belt and pulley. The results of this work have led to the development of a long-life timing belt
