圆锥螺旋弹簧沿轴线方向上升程H一定,在垂直于轴线的平面(称投影面)内的投影为阿基米德螺线(以下简称螺线)(见图1)。用图2所示方法绕制此种弹簧时,料丝由摩擦轮A水平送进,螺线由芯焊D及沿凸轮廓线移动的顶焊C形成,新程由顶焊E垂直低面向外伸出实现。称此系统为原始系统。螺旋弹簧在绕制过程中作平面运动。而匀速送料时弹簧所作平面运动中的转动部分不为匀速转动。对一定机构,顶捍G沿与送料方向相距定值H的平行线移动,而与弹簧轴线的空间距离则是变化的。此时,为形成 Conical coil spring along the axial direction of the lift H must, in the plane perpendicular to the axis (called the projection plane) projection Archimedes spiral (hereinafter referred to as the spiral) (see Figure 1). When the spring is wound as shown in Fig. 2, the material is fed horizontally by the friction wheel A, and the spiral is formed by the core welding D and the top welding C moving along the cam profile. Extend to achieve. Call this system the original system. Helical spring in the winding process for planar movement. The uniform part of the spring movement made by the plane part of the rotation is not uniform rotation. For some institutions, the top defend G along the feed direction and the value of H from the parallel line to move, while the distance from the spring axis space is changing. At this time, for the formation
