And the polar angle and the polar radius was represented into AutoCAD polar coordinate, the involute was drawn through the spline linear tool. And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting.

根据DIN 3960渐开线花键的坐标值，用EXCEL函数功能计算出不同压力角下渐开线的极角和极半径，表示成AutoCAD极坐标并通过样条线工具绘制出渐开线，再用齿顶圆和齿根圆直径截取一段渐开线作为为花键齿面，并用分度圆直径绘制出渐开线齿剖面，经镜像和裁剪便可绘制出渐开线齿形。

Based on the stress analysis to spired axis mechanism,in the aspect of sliding part which smoothes through alveolus intersection, theresearch of parameters optimization, about the middle alveolus of spired axis andthe dimension of sliding part, has been studied. To the problem that the reverseportion at the both sides of spired axis lashed fiercely and fraies quickly, thearticle finely analyses the best curve of alveolus when adding cushiony spring atthe both sides.

在对螺旋轴机构进行受力分析的基础上，从滑块顺利通过齿槽交叉点的要求方面，对螺旋轴中间段齿槽和滑块的尺寸进行了参数优化分析；针对螺旋轴两端曲线齿槽反向段在高速工作时冲击大、磨损快的问题；从减少滑块在齿槽反向段运动的冲击方面，比较分析了圆弧、抛物线、三角函数等曲线作为螺旋轴齿槽反向段曲线的加速度，提出了较优的(来源：ABCab论bf文网www.abclunwen.com)反向段曲线。

To cooperate with new and old parts: although standard zero, components, but in between interchangeable in assembly parts, and to make the optimal coordination between trim, still needs a lot of work, such as the gear and rack, boring if after removal of gear various performance indicators are used by detecting without the need to change, and to replace worn rack, rack and rack positioning pin hole on installation bolt holes and should be first, reoccupy hand crossed positioning drills and tapered reamer to match the drill and match hinge, and after the installation of new and old super-modulus gear mesh clearance to achieve technical standards, this work takes about one day.

。新，旧零部件重新配合过程：尽管标准零，部件间具有互换性，但在装配中，要使新旧零部件间的配合达到最佳状态，仍需大量的修整工作，如镗床的齿轮与齿条，若拆卸后齿轮的各项性能指标经检测尚能使用不需更换，而齿条磨损严重需更换，那么齿条及齿条安装面上的定位销孔和定位螺钉孔就需先划线定位，再用手电钻及锥形铰刀重新配钻和配铰，且新齿条安装完毕后与旧齿轮的啮合间隙需达到技术要求的标准，此项工作需时约一天。
