The mesh stiffness of a pair of helical gears is calculated by substituting the variance of the contact line length for the variance of the instantaneous mesh stiffness.
计算分析认为，双圆弧齿轮的啮合点分布情况是齿轮的轴向周节、同一轮齿上两啮合点在轴向的距离和齿轮的有效宽度的函数。
Analysis shows that the distribution of meshing points is a function of the axial circular pitch, the axial space of two meshing points on a tooth and the effective width of the gear.
在少齿差内啮合传动中，存在多对接近啮合的小间隙齿面于理论啮合点左右，轮齿受力产生的微小变形使得某些对齿面相互接触进入啮合状态。
