Abstract：[Objective]To investigate the influence of a modified tooth surface on the meshing performance of face gear pair,a full tooth surface modification method for face gear was proposed to optimize their meshing performance.[Methods]Firstly,the standard tooth surface was discretized using a digital method,and modification amounts were added at the discrete points to establish a 3D model of the modified tooth surface.Secondly,the influence of face gear modification and cylindrical gear modification on the contact stress,contact trace,and transmission error was analyzed by using the method of loaded tooth contact analysis.Finally,to guide the design of full tooth surface modification of face gear,the effects of both tooth helix and tooth profile modification amounts on contact stress,contact trace,and transmission error were analyzed.[Results]The results show that the meshing performance of face gear modification is better than that of cylindrical gear modification,and a reason-able amount of full tooth surface modification has an obvious effect on the meshing performance of the face gear pair.
