给出了计算外、内正齿轮和斜齿轮抗点蚀几何系数I，以及由齿条式工具（滚刀、齿条刀具或成形砂轮）或小齿轮式工具（插齿刀）生成的外正齿轮和斜齿轮抗弯强度几何系数J的方程式。包括提供一系列典型齿轮组和齿形的几何系数I和J的图表。

Gives the equations for calculating the pitting resistance geometry factor, I, for external and internal spur and helical gears, and the bending strength geometry factor, J, for external spur and helical gears that are generated by rack-type tools (hobs, rack cutters or generating grinding wheels) or pinion-type tools (shaper cutters). Includes charts that provide geometry factors, I and J, for a range of typical gear sets and tooth forms.
