【摘要】 本文主要讨论滚齿过程中渐开线与包络切线之间形成的棱面度问题。许多文献都引用了F.Pohl的棱面度公式和图表。但是,Pohl公式简化时,忽略了微量计算中渐开线上两点曲率半径之间的差值,致使该公式的计算误差相当于JB179-83齿形公差的1～2级。本文应用矢函数法求解棱面度,提高了计算精度,并取得了棱面度顶点的位置,为平整棱面度提供了依据。更多还原

【Abstract】 This paper deals with an analysis of the deviation from the involute form which appears between two enveloping positions of the hob teeth. The basic analysis cited the Pohl’s formula and chart to calculate the distance of the ridges. Owing to omitting the influence of the difference between two curvature radii, it will be brought on the calculate error about one or two accuracy grades in the total profile error. Using the method of vector function obtained the ridgy distances and tried to improve the computational accuracy. Then the top ends of the ridge may be provided scientific basis for smoothing away the ridges.更多还原
