摘　　要：研究了一种具有安装误差耦合的面齿轮传动精确装配有限元模型的建模方法,对面齿轮传动承载接触特性进行了分析。采用数值计算法求得面齿轮和圆柱齿轮齿面离散点以及具有安装误差的齿轮副装配转角,实现了面齿轮传动有限元模型的高精度建模和装配;通过Abaqus二次开发,获得安装误差耦合的面齿轮有限元承载接触分析结果和承载接触特性参数。结果表明,当轴交角误差过大时,会产生应力集中,齿面接触应力相对于无误差情况增大了41.33%;当轴向安装误差超过0.4 mm时,齿面啮合产生干涉;偏置和轴向安装误差耦合的情况下,保持偏置安装误差不变,则轴向安装误差对承载接触特性的影响规律与轴向安装误差单独作用时相同。A modeling method of finite element model for precise assembly of face gear transmission with installation error coupling was studied,and the bearing contact characteristics of face gear transmission were analyzed.The discrete points of the tooth surface of the face gear and the cylindrical gear and the assembly angle of the gear pair with installation error were obtained by the numerical calculation method,and the high-precision modeling and assembly of the finite element model of the face gear transmission were realized.Through the secondary development of Abaqus,the finite element bearing contact analysis results and bearing contact characteristic parameters of face gear with installation error coupling were obtained.The results show that when the shaft angle error is too large,the stress concentration will occur,and the contact stress of the tooth surface increases by 41.33%compared with that without error.When the axial installation error exceeds 0.4 mm,the tooth surface meshing will produce interference.In the case of the coupling of offset and axial installation error,the influence of axial installation error on the bearing contact characteristics is the same as that of the axial installation error when the offset installation error is kept constant.
