摘　　要：基于面齿轮传动的特点,为获得准确可靠的面齿轮的齿距偏差,参考其他类型齿轮齿距偏差定义,提出相邻齿面的面齿轮齿距偏差曲面及齿距法向偏差曲面概念,构建基于三坐标测量机获得面齿轮齿距偏差曲面及齿距法向偏差曲面方法:通过三坐标测量机得到实际面齿轮齿面数据,构建其真实数值齿面,选定基准齿面,将相邻真实齿面旋转理论夹角γ得到齿距偏差曲面。给出对面齿轮齿距偏差曲面进行分析获取齿距偏差数据的方法与步骤。研究结果表明:面齿轮齿距偏差曲面、齿距法向偏差曲面概念及测量方法、齿距偏差数据获取方法的提出为面齿轮制造误差评价提供一种新方法。To evaluate the accuracy grade of face gear and perform dynamic analysis, the pitch deviation surface and normal deviation surface relative to the real tooth surface were proposed. Firstly, the concepts and calculation method of pitch deviation surface and normal deviation surface of face gear based on the coordinate measuring machine （CMM）, were discussed. According to the measured real gear face data, the real numerical gear tooth surface was reconstructed. The adjacent contacting gear surface was rotated at the theoretical angle y based on one real gear surface, and the pitch deviation gear surface was derived. Finally, an experiment was performed to illustrate and validate the proposed method, which provides the basic data for the subsequent dynamic characteristic analysis. The results show that the proposed concepts and calculation method of pitch deviation surface provide a new strategy to evaluate the manufacturing error of face gear.
