Embodiment Construction

[0006] National standard nuts and national standard flange nuts have good connection performance, but their anti-seismic and anti-loosening capabilities are limited. With the reloading and high-speed operation of various mechanical equipment, the loosening of nuts and bolts becomes more and more prominent. Increase the diameter of the flange surface of the flange nut, add bumps, circumferential arcs, and high teeth on the outermost edges of the flange nuts and bolts, so that the bottom surface of the flange and the workpiece are completely suspended, and the flange bumps, circumferential arcs 1. The high teeth contact the workpiece first. When the outer edge is under the local force of the bumps, circumferential arcs, and high teeth, the deformation will be large. The edge of the flange surface that does not contact the workpiece will also disperse part of the force and store elasticity at the same time. potential energy. The tall tooth itself is thin and tall, with an aspect ...

Abstract

The invention discloses a flange bump, a circumferential arc and a high-tooth lock bolt and a nut, and belongs to the technical field of anti-loose fasteners. Flange face of a flange locknut and a bolt should be large enough, an annular platform is arranged on the outermost ring of the flange face, semicircular protruding points, circumferential arcs and high teeth are evenly arranged on a flange annular platform, the semicircular protruding points, the circumferential arcs and the high teeth enable the flange face to be suspended, the protruding points, the circumferential arcs and the high teeth make contact with a workpiece firstly during installation, stress is conducted firstly, and force is transmitted to the flange face; due to local stress, local deformation is large, the flange edge also shares part of the force and part of the deformation, a root foot of each high tooth is provided with a small-angle inclined plane, the high teeth can generate transverse deformation under the action of fastening force and friction force, and the deformation is overlapped with flange deformation. By means of the design, the elastic coefficient is small, the elastic variation is large, and the elastic potential energy stored by the flange is large, and the anti-vibration and anti-loosening capabilities are high.

Description

technical field [0001] The invention relates to a kind of anti-loosening nuts and bolts with flange bumps, circumferential arcs, and high teeth. A device for preventing nuts and bolts from loosening by elastic potential energy belongs to the technical field of anti-loosening fasteners. Background technique [0002] Preventing thread loosening has always been the goal pursued by engineers and technicians. Since the appearance of thread, the problem of loosening has not been solved well. Locknuts have appeared in recent decades, and there are many forms. Everyone has different research directions and different research results. Among them, the representative work should be the tooth-changing locknut launched by the American Spielock Tool Company in 1975. In 2001, Spielock set up a factory in Shanghai to produce variable tooth locknuts. The advantages of Spirax nuts are anti-loose structure, stable and reliable, reusable, and not affected by changes in ambient temperature. ...
