当螺纹加工超差或螺纹损伤时,应用钢丝螺套进行修复的方法在国外应用较为普遍,但国内工程机械上刚有应用。用此法方便快捷,牢固可靠。现介绍如下。 钢丝螺套是用高强度、高精度、菱形截面的钢丝绕制成的,可用来修复螺纹连接件。其菱形截面的内外侧两个对角均为60°,缠绕后一角在外表面构成外螺纹牙型,一角在内表面构成内螺纹牙型,如图1所示。
When the thread processing tolerance or thread damage, the application of wire thread sheath repair method is more common in foreign applications, but the domestic construction machinery has just been applied. Use this method is convenient, solid and reliable. Now introduced as follows. Steel wire sets are made of high-strength, high-precision, diamond-shaped cross-section of steel wire can be used to repair threaded connectors. The rhombus cross section of the inside and outside of the two diagonal are 60 °, after winding a corner on the outer surface of the outer thread form, a corner of the inner surface of the internal thread form, as shown in Figure 1.
