Abstract：[Objective]To address the problem that pure rolling bevel gears are prone to angular velocity mutation,vibration,and noise excitation under the influence of mounting errors,a tooth surface design method with low sensitivity to mounting errors was proposed.[Methods]Firstly,based on the influence of installation errors on angular velocity,the transmission error curve was preset as a parabolic type.Secondly,the theoretical tooth surface of the pinion was modified using the preset transmission error curve to establish a mathematical model of the target tooth surface.Finally,a 3D solid model of the modified bevel gear was constructed,and tooth contact analysis was performed.[Results]The results show that the derived transmission error curve is consistent with the preset curve,validating the effectiveness of the modification.The actual meshing points of the optimized tooth surface deviate from the edges,and the overall contact area centers on the tooth surface,effectively avoiding edge contact and stress concentration.
