采用碟形砂轮磨齿展成偏置面齿轮，通过碟形砂轮齿廓修形及控制砂轮中心运动实现偏置面齿轮齿面拓扑修形，建立了偏置面齿轮的磨齿和啮合坐标系，推导了拓扑修形偏置面齿轮齿面方程，建立了考虑安装误差的拓扑修形偏置面齿轮轮齿接触分析、承载接触分析模型，并编制了相应计算机程序，最后通过算例进行了分析． 算例分析表明:碟形砂轮磨削偏置面齿轮是可行的;偏置面齿轮齿面几何不对称，偏置影响接触印痕、承载传动误差，但不影响几何传动误差;对偏置面齿轮拓扑修形，可有效改善偏置面齿轮副啮合性能．

Firstly,an offset face gear was generated by using a disk wheel,and the topological modification of the gear was achieved through disk wheel's profile modification and center movement control.Secondly,the coordinate systems for grinding and meshing were established,and tooth surface equations of the gear were deduced.Then,by taking into consideration misalignment and topological modification,computational models for tooth contact analysis and loaded tooth contact analysis of the offset face gear pairs were established,and the corresponding computer pro- gram was developed.Finally,some examples were given.The results show that (1) the method of grinding offset face gear with disk wheel is feasible; (2) the tooth surface of the offset face gear is geometrically asymmetrical,and the offset value has an effect on contact patch as well as loaded transmission error but has little influence on transmission error; and (3) the meshing performance of offset face gear pairs can be effectively improved by means of topological modification of the offset face gear.
