摘　　要：根据面齿轮加工原理和方法,分析刀具和工件的相对位置关系,建立加工坐标系,运用微分几何和啮合原理,推导含修形的面齿轮理论齿面方程,给出齿面待测点理论坐标处法矢量计算公式和齿距测量基圆找正方法,基于海克斯康GLOBAL STATUS575型三坐标测量机编制测量程序对加工出的面齿轮进行实测,并对实测数据进行补偿得到该面齿轮的齿距偏差。结果表明,给出的基于三坐标测量机测量面齿轮齿距偏差的方法逻辑严谨、思路清晰,是面齿轮精度评定的一种可行、实用方法。On the foundation of principle and method of face gear machining, the relative position between tool and gear is analyzed and process coordinates are established. According to the differential geometry and meshing theo- ry, the equation of theoretical tooth surface is established. The calculation formula of theoretical coordinates and nor- mal vector of points and the alignment method of pitch measure base circle are given. The actual measurement of the manufactured face gear is carried out by the measuring program based on the Hexagon GLOBAL STATUS575 coordinate measuring machine, and the deviations are obtained after measuring the surface along nonnal direction and making com- pensation for the measuring data.
