【Abstract】 The stress of the teeth of a standard straight spur gear was calculated by means of finite element method(FEM),and the regularity of contribution of stress and the extreme stress on dangerous section of the teeth were obtained.The results obtained by FEM is more precise than that obtained by traditional method.So FEM provides a new method of the teeth bending fatigue strength caculation of teeth of the geer.更多还原
