摘要
根据面齿轮专用磨齿机的机械结构,提出了偏置曲线修整方法,设计了砂轮修整装置,并运用VERICUT软件进行修整加工仿真.推导了含各类修整误差情况下面齿轮的齿面方程表达式,并运用MATLAB软件生成了齿面误差云图,为修整过程的误差补偿提供了理论参考.最后进行了磨削及检测试验,将检测结果与误差云图对比,分析可能产生这种误差的原因,并在修整过程中进行误差补偿,使齿面最大法向误差值减少了31.14%,面齿轮齿形精度得到了提高.
According to the mechanical structure of a face gear grinding machine,an offset curve dressing method and a grinding wheel dresser were designed,and simulation and analysis of the dressing process were performed with VERICUT.The equation of face-gear tooth profile with error caused by wheel dressing process was derived and the error cloud of face-gear tooth profile was created with MATLAB,providing theory references for the research on error compensation of dressing process.The grinding and testing experiments were carried out at last.By comparing the result with the error cloud,the reason was analyzed and the error in the dressing process was compensated;the maximum tooth profile normal error was reduced by 31.14%,and the precision of the tooth surface was improved.
