摘　　要：基于螺旋锥齿轮齿面分析的数学模型,采用最优化算法和一种新的计算齿形误差的方法,计算了误差齿面与理论齿面在理论齿面法线方向的齿形误差。通过引入机床调整误差和刀具参数误差,分析了各种误差对螺旋锥齿轮齿形的影响规律,以图形的方式表示了误差齿面相对于理论齿面的偏离方向以及误差值的大小,为机床的精度设计、齿形误差的修正以及指导实际加工提供了理论依据。通过实际的磨齿加工和检测对算法以及分析结果进行了验证。Based on the mathematical model for the tooth form analysis of spiral bevel gears, the tooth form errors between the theoretical tooth flank and the inaccurate one, in the normal direction of the theoretical tooth flank, were calculated by applying optimization algorithm and a new computing method. By introducing the machine setting errors and cutter parameters errors, the effect of various errors on the tooth form of spiral bevel gears was analyzed. The deviating direction from the theoretical tooth flank and the values of tooth form errors were expressed by graphics. The results provide a reference for precision design of machine tools, correction of tooth form errors and practical processing. The algorithm and analysis results are validated via experiment.
