传统的螺母防松动办法多是刚性的.我们在高炮的行军、打靶实践中摸索出一套用弹性预紧力预防螺母松动小招法.现介绍如下:a).拧紧螺母后,再在螺杆上紧套一段乳胶管,或者紧套一些用车内胎剪制的橡胶圈.如图1所示.b).拧紧螺母后,再在螺杆上紧系几圈橡皮筋.如图2所示.上述两法,是利用乳胶管或橡胶圈受胀变形而产生的弹性预紧力防松的,因此,抗冲击振动的能力很强.c).预先在螺母上钻几个小孔并攻成螺孔(常 Traditional anti-loose nut approach is more rigid .We marched in the artillery, shooting practice to find out a set of elastic preload to prevent nut loose small move method are as follows: a). Tighten the nut, and then in the screw Tighten the sleeve of a latex tube, or a few sets of car tires with a rubber ring, as shown in Figure 1. b) Tighten the nut, then the ring screwed a few laps rubber band. The above two methods, is the use of latex tube or rubber ring by inflation deformation of the elastic preload prevention of loose, so the ability of anti-shock vibration is very strong .c). Pre-drilled a few holes in the nut and attack Screw hole (often
