Involute curve contour lines is an important one machine parts.

0引言渐开线是机器零件中重要轮廓曲线之一。

From FEM, the contact stress obeys the semi-ellipse distribution and the Mises stress and shear stress are also consistent with contact mechanics theory, but there exists offset or deflection in the symmetric lines of stress distribution, which originates from tooth bending deformation.

由有限元方法得到的渐开线轮齿的接触应力符合Hertz理论中的半椭圆分布规律，Mises应力和剪应力分布也符合接触力学理论，但应力分布的对称中心存在偏离或者偏斜现象，分析认为，是由于轮齿弯曲变形造成的。

The points-line meshing gear is different from involute gear in choice of helix angle.

点线啮合齿轮螺旋角β的选择，改变了渐开线齿轮为凑中心距或者从优化角度来选取β值的情况。
