滚珠

The mechanics model of a ball screw was developed considering the factor of lead angle,and the main curvature of the helical surface was deduced using differential geometry method,and the effect of lead angle on the elastic deformation was analyzed.

考虑螺旋升角的因素，建立了滚珠丝杠副的受力模型，应用微分几何理论推导了螺旋面的主曲率，并进一步分析了螺旋升角对滚珠丝杠副弹性变形的影响。

The equations for the helicoid and cross section of a ballscrew are worked out and a numerical integral method for the computation of the moment of inertia of the cross section is proposed.

建立了滚珠丝杠的螺旋面方程及横截面方程，提出一种精确计算滚珠丝杠横截面惯性矩的数值积分法，计算结果表明，传统的简化方法将造成20％以上的计算误差。
