【摘要】：为了减小成形磨齿过程中齿轮装夹位姿和受力的变形误差、提高成形磨齿的加工精度,基于渐开线圆柱齿轮的成形磨齿原理,建立含齿轮装夹位姿误差的成形磨齿数学模型,依据渐开线圆柱齿轮的评价指标提出一种齿面误差的评定方法,并分析了齿轮装夹位姿误差对成形磨齿精度的影响,分别研究了齿轮装夹偏心误差、倾角误差、偏心与倾角耦合误差对成形磨齿精度的影响规律,得到3种不同条件下的齿面偏差对齿轮装夹位姿误差的误差敏感项。通过成形磨齿加工实例验证了所得规律的正确性,表明齿轮装夹位姿误差耦合作用规律可为齿圈装夹受力变形提供参考,同时其研究方法可为成形磨齿误差溯源和误差辨识提供依据。
[Abstract]:In order to reduce the deformation error of gear clamping position and force, and improve the machining precision of forming gear, based on the forming grinding principle of involute cylindrical gear, the mathematical model of gear forming grinding with gear clamping position error is established. According to the evaluation index of involute cylindrical gear, a method of evaluating tooth surface error is put forward, and the influence of gear clamping position error on forming grinding precision is analyzed. The gear clamping eccentricity error and inclination angle error are studied respectively. The influence of the coupling error of eccentricity and inclination angle on the precision of gear grinding is studied. The error sensitive terms of tooth surface deviation to gear clamping position error under three different conditions are obtained. The correctness of the obtained rule is verified by the example of forming grinding tooth machining. The results show that the coupling law of gear clamping position and attitude error can provide a reference for the force deformation of gear ring clamping, and the research method can provide the basis for error tracing and error identification of forming grinding gear.
