摘　　要：面齿轮传动由于其独特的传动优点,成为航空传动的主要研究方向.根据面齿轮传动原理,建立面齿轮加工坐标系,得到了面齿轮齿面方程,分析了面齿轮齿顶变尖和齿根根切的限制条件,同时根据实际算例讨论了面齿轮内外半径随压力角变化的规律,所获得的结论对面齿轮的设计具有参考价值.最后分析面齿轮的滚切原理,根据齿轮啮合原理,建立面齿轮滚刀型面方程,采用数值计算方法,得到滚刀型面离散三维坐标值,借助三维造型软件得到面齿轮滚刀基本蜗杆三维模型.Face-gear drives become the main direction of research for aeronautical drives because of their special advantages. The applied coordinate systems of face-gear were set up and the equation of face-gear tooth surface was established, then the face-gear tooth surface constrain conditions for dedendum undercutting and addendum pointing were analyzed based on the face-gear transmission theory, at the same time, the disciplines were discussed on the relationships between pressure angle and the face-gear outer ＆ inner radius in keeping with the practically calculated examples. The calculating results are useful for designing the face-gear drive. In the end, the face-gear hobbing theory was analyzed, according to the gear geometry and applied theory, the hobbing surface equation was founded. The discrete values of three-dimensional coordinates for the hobbing surface were calculated by using the method of numerical calculation. The three-dimensional basal worm model of face-gear hob was designed by recurring to the three-dimensional software.
