MSR锁紧螺母在结构上有独到之处。螺母本体的内孔和外圆上各加工一沟槽,螺孔中心的圆周上等距分布3～8个内六角螺栓。这种结构,使该螺母既具有很强的锁紧力,又能消除端面跳动,并可调整与接触面的接触状态。 本文就该螺母的结构、性能、使用方法做了具体的介绍。图11幅,表1个。 MSR lock nut is unique in structure. The inner bore and the outer circle of the nut body respectively process a groove, and the circumference of the screw hole center is distributed with 3 to 8 hexagon socket head cap bolts equidistantly. This structure, so that the nut has both a strong locking force, but also eliminate the end beating, and contact with the contact surface can be adjusted. In this paper, the structure of the nut, performance, the use of methods to do a specific introduction. Figure 11, Table 1.
