Description

Locking locknut assembly

Technical Field

The utility model belongs to the technical field of the nut processing, a locking nut component that loosens is related to.

Background

At present, the anti-skidding locking effect of the nut is enhanced by the anti-loosening washer with the dentate bulges arranged on the upper surface and the lower surface when a workpiece is fastened, but the locking effect is not obvious when the existing anti-skidding nut is applied to a place with large vibration and is easy to fall off. There is a packing ring structure, adopts two packing rings that have the skewed tooth, strengthens locking effect through the intermeshing of skewed tooth, and this kind of mode locking effect is obvious, but when narrow and small space installation, two packing rings have increased the degree of difficulty of installation, have reduced work efficiency, simultaneously, also need to invest into more resource production packing rings and match the nut.

The existing locking and anti-loosening nut basically adopts a single mode to lock and prevent loosening, two independent parts are often adopted to assemble when the nut is assembled, and therefore when the nut is assembled, the central axis of the nut and the central axis of the bolt can be dislocated due to large assembling force, so that the thread is damaged, and the service life of the nut is influenced.
