本文论述了钢丝螺套的特点和自锁性能,分析了钢丝螺套装入螺孔后的受力情况,推导出在假设的边界条件下钢丝螺套装入螺孔后的变形公式.计算出允许的过盈量,分析了过盈量与紧度的关系.以及在自由状态下确定钢丝螺套外径尺寸的方法,并对钢丝螺套的强度进行了校核计算. 本文还介绍了对M4～M33的钢丝螺套进行径向弹性试验的方法,并根据钢丝螺套的弹性试验结果,对理论计算的和国外引进的钢丝螺套在装配后实际的过盈量和紧度、进行比较,推荐了各种规格尺寸的钢丝螺套的过盈量范围.
In this paper, the characteristics and self-locking properties of the steel wire sleeve are discussed, the force of the steel wire sleeve after it is installed in the screw hole is analyzed, and the deformation formula of the steel wire sleeve under the assumed boundary condition is deduced. The amount of interference, the relationship between interference and tightness, and the method of determining the outer diameter of the thread washer in the free state, and the strength of the thread was measured and checked.In addition, M33 of the wire sleeve radial elastic test method, and according to the elastic test results of the wire screw sleeve, the theoretical calculation and the introduction of foreign steel wire sets in the assembly after the actual interference and tightness, are compared, recommended A variety of sizes and sizes of wire thread interference range.
