据苏联《机器制造者》杂志报道,介绍了一种能提高螺纹连接强度的新方法。采用这种方法能使载荷更均匀地分布到组合螺母的螺纹上。如图所示,把螺母2和螺母3拧到螺杆4(螺栓或螺柱)上。用手轻轻地将螺母2拧紧到被连接零件1上。利用这种方法调整螺纹连接的间隙,即调整螺母2的端面与被连接零件表面的间隙和螺母2螺纹与螺杆螺纹的间隙。调整螺纹连接间隙时,可用手拧螺母3,使螺
According to a report by the Soviet “Machine Builder” magazine, a new method to increase the strength of the thread connection was introduced. With this method, the load can be distributed more evenly to the threads of the combination nut. As shown, screw nut 2 and nut 3 onto screw 4 (bolt or stud). Gently tighten the nut 2 to the connected part 1 by hand. Use this method to adjust the thread connection gap, that is, adjust the gap between the end face of the nut 2 and the surface of the connected parts and the gap between the thread of the nut 2 and the thread of the screw thread. Adjust the thread connection gap, available hand-tighten the nut 3, the screw
