JB179-83《渐开线圆柱齿轮精度》的 K 个周节累积误差⊿F_p (?)定义为“在分度圆上,K个周节间的实际弧长与公称弧长的最大差值。K 为2到小于 z/2的整数。”在应用时,对该项误差的测量方法和计算方法上有着不同的认识。得到的结果有的差别不大,有的差别较大,影响齿轮质量的评定。为此需要分析研究,以便统一认识,共同提高。下面就作者在标准宣贯中和学术讨论会上所了解到的情况进行分析比较。
The cumulative error of K weeks for JB179-83 “Involute Cylindrical Gear Accuracy” ⊿F_p (?) Is defined as “the maximum difference between the actual arc length and nominal arc length over K weeks on the indexing circle. K is an integer from 2 to less than z / 2. ”There is a different understanding of the method of measurement and calculation of this error when applied. Some of the results obtained are not very different, some differences, affecting the quality of gear assessment. This requires analysis and research in order to unify understanding and common improvement. Below the author in the standard publicity and symposium learned about the situation analysis and comparison.
