对于相啮齿轮端面齿廓相互关系的分析表明，目前使用的几种基准齿形，当螺旋角传动比都比较大时，存在齿形干涉的危险。

Then, it is indicated that the gearing used presently, while its helix Angle and ratio are both big enough, is in danger of interference.

阐述了齿轮的齿廓、基本齿廓和齿条型刀具齿廓三者间的相互关系。

This paper expounded the interrelations among gear's flank profile, gear's basic flank profile, and rack cutter's flank profile.
