摘要
基于对渐开线斜齿圆柱齿轮传动接触线长度的精确计算，提出对现行标准中斜齿轮传动强度计算的重合度系数进行修正，可提高齿轮传动设计计算的精确性．
The amendment on coincidence coefficient is proposed in strength ca1culation of involute helical gear trains of present standards'based upon the accurate calculation of contact line length of involute helical gears.. It can increase the accuracy of design calculation of gear trains.
