Title: Impact of coefficient of tooth width on bending stress of face gear
Abstract: Based on engagement theory of face gear drive,the three-teeth geometric model of face gear was developed to calculate the bending stress.The design parameters were confirmed using orthogonal experiment method,and the bending stress of face gear was calculated by finite element analysis(FEA).Regarding the face gear as a rack,the expression of bending stress of face gear and the relationship between bending stress ratio and coefficient of tooth width were obtained.The results show that the maximum bending stress location is in tooth root,and the distribution of bending stress is parabolic line approximately along the tooth width of the maximum bending stress location.The relationship between the ratio of bending stress and the coefficient of tooth width is approximately linear and the mean relative error is 6.17%.The coefficient of tooth width and teeth number affect the bending stress greatly.In order to diminish the effect of coefficient of tooth width and teeth number on the bending stress,the results appropriately magnifies by 5% in application of the expression of bending stress of face gear when the teeth number is less than 90 and the coefficient of tooth width is less than 3.
