Problems solved by technology

This structure ensures that the nut will not loosen under low load conditions, but the strength of the nut is reduced due to the longitudinal cutting of the nut and the pin hole crossing the nut body, and the pin is easy to deform the bolt thread, which cannot guarantee multiple times reuse

Embodiment 1

[0022] Such as Figures 1 to 6 As shown, this embodiment is composed of a nut body 1 , a washer body 2 , an axially extending body 5 , and a flange inlay body 6 . Wherein, the inside of the nut body 1 is provided with an internal thread 3 . An axial protruding body 5 is provided on the nut body 1 , and a nut groove 4 is provided beside the axial protruding body 5 . A flange inlay 6 is arranged on the washer body 2, and the flange inlay 6 is embedded in the nut groove 4. The height of the flange inlay 6 is greater than the depth of the nut groove 4, and the thickness of the flange inlay 6 is smaller than that of the nut. The width of groove 4. The height of the axially protruding body 5 is equal to the thickness of the washer body 2 , and the outer diameter of the axially protruding body 5 is equivalent to the inner diameter of the washer body 2 .

[0023] The axial extension body 5 is provided with two pairs of extension body narrow grooves 7 in the radial direction, and th...

Abstract

The invention relates to a locknut shim insert combination external member which comprises a nut body. The external member is structurally characterized by also being provided with a gasket body, wherein the gasket body is provided with a flange insetting body; the nut body is provided with a nut groove and an axial protruding body; the flange insetting body is embedded in the nut groove; and the gasket body is covered on the axial protruding body. The external member provided by the invention has the advantages of reasonable and simple structure design, good anti-loosing effect, long service life, safety and reliability; and the thread is free from being damaged.

Description

technical field [0001] The invention relates to a locknut washer inlaid combination set. Background technique [0002] Commonly used anti-loosening methods for ordinary threaded fasteners mainly include increasing the friction between thread pairs, directly locking with stoppers, and destroying the relationship between thread motion pairs by punching points, etc. The locking of the stopper is limited by the shape and size of the connected piece, and the scope of application is limited. Punching and other methods are suitable for occasions that do not require disassembly. The anti-loosening methods used by most fastener products are unreasonable, such as spring washers, etc. The improvement of the anti-loosening performance is at the expense of uneven axial tension of the thread teeth, which may easily lead to a decrease in the fatigue strength of the bolts. The Chinese patent whose publication number is CN 101338777 discloses a kind of anti-loosening nut and the method for...
