摘　　要：重合度是齿轮传动的重要性能指标,对面齿轮传动而言,没有类似渐开线齿轮传动的重合度计算公式。文中给出面齿轮传动重合度定义,基于有限元轮齿接触分析方法给出面齿轮传动重合度计算的时间差法。针对抛物线齿廓修形面齿轮,对比计算了空载与加载重合度、标准面齿轮传动与修形面齿轮传动重合度。计算结果表明:1)修形面齿轮传动重合度低于标准面齿轮传动重合度;2)加载修形面齿轮传动重合度较空载修形面齿轮传动重合度有较大提高。文中工作为面齿轮传动重合度计算提供一种方法。The contact ratio is an important performance index of gear transmission,but there is no computational formula of contact ratio for complex tooth surface transmission,such as face gears.The definition of face gear contact ratio is given,and the method of time difference which can be used to calculate face gear contact ratio based on the finite element gear tooth contact analysis is proposed.The contact ratio of loaded and unloaded modification face gear and standard face gear are calculated.The calculation results show that：1）the contact ratio of modification face gears reduce greatly compared with the standard face gears,2）the contact ratio of loaded modified face gears increase greatly compared with unloaded gears.A method to calculate face gear contact ratio is proposed.
