相交轴变齿厚齿轮啮合原理的研究

Study on Gearing Theory for Changing Thickness Gear Pair with Intersecting Axes

研究了相交轴变齿厚齿轮的啮合原理，通过计算提出：为了使两齿轮啮合时其节锥母线为直线，变齿厚齿轮的变位系数变化不成线性：选择变位系数时，应同时满足轮齿不根切、齿顶不变尖和不发生渐开线干涉诸条件。同时还提出了变齿厚齿轮因轴交啮合而引起的齿形误差问题。

This paper expounds the gearing theory for changing thickness gear pair with intersecting axes.By calculation,a conclusion is reached.As a result of the straight pitch cone generator on the gear pair,the changs of their modification coefficients are not linear.When modification coefficients are chosen,the all requirements of no undercut、no sharp top and no gearing interference must be met.Besides,the profile errors in intersecting gearing of the gear pair exist objectively.
