摘要
根据圆环螺旋线的形成原理,建立了圆环螺旋弹簧的轴螺旋线的参数方程,推算了螺旋线起点的切线倾角,并在AutoCAD环境下,将基圆沿螺旋线起点切线方向"拉伸"获得圆环螺旋弹簧造型。根据工程实际应用情况,研究了圆环螺旋弹簧造型条件,即圆环的两半径与螺旋弹簧基圆半径及圈数的关系。最后,以U型螺旋弹簧造型为例,讨论了圆柱螺旋弹簧与圆环螺旋弹簧的连接造型方法。
According to the principle of the helix on torus,the parametric equation of helix of spiral spring on torus is constructed,and the tangent angle of the start point of helix is given.The spiral spring modeling is obtained by Extruding a circle to the tangent direction of the start point of helix.The modeling factors that two radius of torus and the radius of the circle and the ring number of the spiral spring are studied.Finally,the butting method of the spiral spring on cylinder and the spiral spring on torus is discussed by the example of the modeling of U form spiral spring.
