摘　　要：基于车齿刀与面齿轮车齿加工的数理模型,将插齿加工作为理论齿面,建立了车齿加工的齿面偏差模型;采用增量方式,分析了车齿加工参数(偏置距、切深、轴交角、滚比)对齿面精度的影响规律,给出了面齿轮齿面偏差比例修正方法。车齿加工齿面偏差主要集中在4个顶点位置,齿面偏差对滚比修正最为敏感,对偏置距不敏感。采用3参数偏差敏感性矩阵,确定了齿面偏差与加工参数之间的比例关系。通过两次试切,实现了齿面偏差的修正,验证了比例修正方法的可行性。Based on the mathematical model of gear turning cutters and face gears,a tooth surface deviation model for gear turning is established using gear shaping as the theoretical tooth surface.Using the incremental method,the influence of machining parameters such as offset distance,cutting depth,shaft intersection angle,and rolling ratio on tooth surface accuracy is analyzed,and a method for correcting the tooth surface deviation ratio of face gears is presented.The tooth surface deviation in gear turning is mainly concentrated at four vertex positions,and the tooth surface deviation is most sensitive to the correction of the roll ratio,but not to the offset amount.Using a three-parameter deviation sensitivity matrix,the proportional relation between the tooth surface deviation and machining parameters is determined.Through two trial cuts,the tooth surface deviation is corrected,and the feasibility of the proportional correction method is verified.
