【Abstract】 Motion and power are transmitted by the teeth of the belt and the pulley in the timing belt transmission. For a new type high tooth timing belt, the improvement of loading capability is realized by the optimization of teeth profile parameters. In order to test the optimal parameters of belt teeth, a non linear FEM is applied to the analysis of belt teeth working process, and geometric and material nonlinearities are considered. The stress distribution of belt teeth and the position and the value of the maximal stress are obtained from the calculation, and these results can be taken as the theoretical basis of the analysis of the failure mode of belt tooth.更多还原
