中文摘要：

基于面齿轮传动啮合原理,建立了含安装误差的面齿轮齿面方程,进而得出了面齿轮齿面主曲率及接触应力的计算方法。在此基础上,分别分析了轴向偏移误差、轴交角误差和轴交错误差对面齿轮传动的接触轨迹与接触应力的影响规律。研究结果表明：各项误差条件下,接触应力均从齿顶到齿根逐渐变小;所分析的误差中,轴交角误差与轴交错误差对面齿轮的接触轨迹与接触应力的影响较大,且当轴交角误差为负或轴交错误差为正时,接触应力仿真值均明显高于无误差时的接触应力正常值,因此在安装面齿轮副时,应该严格控制此二项误差的下上偏差。

英文摘要：

Based on the meshing principle of face gear drive,a surface equation has been established of the face gear with the installation error,thus obtaining the calculation method of the main curvature and contact stress of the tooth surface of face gear.On this basis,a respective analysis has been made of the influence of axial deviation error,axial angle error and axial staggered error on the contact trajectory and contact stress of the face gear drive.The results show that the contact stress decreases gradually from the addendum to the root under various error conditions.According to the error analysis,the shaft angle error and axial across error are the most important influential factors on the contact trajectory and contact stress of the face gear,when the angle error is negative or axis error is positive in its value,the contact stress simulation values are significantly higher than those normal contact stress without errors.Therefore,it is highly recommended that the upper and lower deviation of these two errors be strictly controlled when installing the face gear pair.
