摘　　要：梯形花键具有导向性好、自动定心等特点,在低速、大转矩传动领域有一定的应用。应用齿廓法线法对梯形花键轴的滚刀齿廓进行了公式解析,同时对其成型刀具截型进行了公式推导。分析梯形花键副的应力集中问题,提出并计算了替代梯形外花键的渐开线齿形,并计算了齿廓偏差,为相关零件的国产化及使用提供一定的参考。The trapezoid spline has the characteristics of good guidance and self-centering,and its appli⁃cation range has been extended to the field of low-speed and high-torque transmission.Based on the tooth pro⁃file normal line method,the formula of the hob tooth profile of the trapezoid spline shaft is analyzed.At the same time,the formula for the cross-sectional shape of the forming cutter is derived.Finally,the tooth profile deviation of the involute spline shaft instead of the trapezoid spline shaft is calculated.It will provide a certain reference for the actual use and localization of related parts.

关 键 词：梯形花键 滚刀齿廓 刀具截型 齿廓偏差
