摘要
钢丝螺套是用强度、精度的冷轧菱形奥氏体不锈钢丝(通常是SUS304,抗拉强度≥1400N/mm2)加工形成的螺旋线圈线圈。在未安装状态下,钢丝螺套外径大于内螺纹孔直径。这个差别提供了螺纹套由于径向膨胀产生的内在弹性作用,从而保障了螺纹良好的定位和连接的稳定性。安装过程中,通过安装工具施加径向的外力使钢丝螺套外径收缩,从而使钢丝螺套能够顺畅旋入螺纹底孔。
产品介绍
钢丝螺套是用强度、精度的冷轧菱形奥氏体不锈钢丝(通常是SUS304,抗拉强度≥1400N/mm2)加工形成的螺旋线圈线圈。在未安装状态下,钢丝螺套外径大于内螺纹孔直径。这个差别提供了螺纹套由于径向膨胀产生的内在弹性作用,从而保证了螺纹良好的定位和连接的稳定性。安装过程中,通过安装工具施加径向的外力使钢丝螺套外径收缩,从而使钢丝螺套能够顺畅旋入螺纹底孔。
传统的螺纹连接中,75%以上的荷载集中于前三个螺牙上,应力较为集中,决定了螺纹的极限承受强度和使用寿命均较低。钢丝螺套的诞生,实现了低强度金属材料进行高强度连接的目的。钢丝螺套的可变形特点使其能平均分配负载和张力,具有很好的螺旋上升角;同时,全部长度的钢丝螺套可以用来平衡螺距和螺旋上升角本身的缺陷。因此钢丝螺套实现了螺丝和基体母材之间理想的力量传递,使每个螺牙所承受的负载更加趋向于平均,螺纹的寿命也随之大大延长。钢丝螺套的这种工作原理可同时适用于静态和动态两种工作状态。
