Abstract：[Objective]To analyze the meshing performance of the face gear pair,a method for calculating the meshing area of the face gear tooth surface was proposed.Based on this,the influence of misalignment on the meshing area was revealed.[Methods]Firstly,a meshing coordinate system for the face gear pair was established,and the tooth surface equation for the face gear was derived based on the gear meshing principle.Secondly,a contact analysis model for the face gear pair was developed,and a meshing area calculation model for the face gear pair was derived using numerical integration and curve interpolation.Then,the influence of axis offset error,axis angle error,and axis alignment error on the meshing area of the face gear pair was analyzed.Finally,the correctness of the meshing area calculation method and the influence of misalignment was verified through the finite element method.[Results]The results show that the misalignment has an impact on the meshing contact area,and the influence law is related to the offset direction of the contact trajectory.Among these error types,the axis angle error has the greatest impact on the meshing contact area,followed by the axis offset error,and the axis alignment error has the least impact.
