Problems solved by technology

However, this kind of bearing nut has a semicircular rolling groove on the side plane of the nut, and rolling elements are placed in the rolling groove to make the rolling elements roll between the nut side plane and the rolling element cover to achieve the purpose of loosening. , because the rolling body can only roll in the rolling groove, this determines that the nut can only rotate in a single direction in the direction of the nut side plane, and only has a single direction of rotation and anti-loosening effect. It is a bearing nut with plane rolling. , it cannot achieve rotation and anti-loosening in all directions, and the work reliability is low

Embodiment Construction

[0016] Joint bearing type nut of the present invention, embodiment is as figure 1 As shown, it includes a nut 1 and a cover plate 2. The end of the nut 1 in contact with the cover plate 2 is provided with a nut end 11, and a positioning step 12 is formed between the nut end 11 and the nut body. The outer surface of the nut end 11 is Protruding conical surface or arc surface, the corresponding part of the cover plate 2 is provided with a concave hole 21 that is compatible with the nut end 11, and the cavity surface of the concave hole 21 is a concave conical surface or arc surface, and the concave hole The center of 21 is provided with a through hole 22 larger than the diameter of the bolt. In use, the nut head 11 of the nut 1 is fitted into the concave hole 21 of the cover body 2 . The side of the concave hole 21 extends axially and shrinks radially to form a clamping edge 23 , which is movably clamped on the positioning step 12 of the nut, so that the cover plate 2 is movabl...

Abstract

The present invention discloses a knuckle bearing type nut. It is characterized by that the knuckle bearing working principle is applied to the nut in the fastening piece, on the end head of the nut a projected or recessed cone surface or curved surface is made, and on the cover plate a corresponded reccessed or projected cone surface or curved surface also is made, the above-mentioned both are movably jogged into the invented knuckle bearing type nut. It can more effectively prevent the nut from lossening, and can prevent the nut from falling off.

Description

technical field [0001] The invention relates to a fastener, in particular to a joint bearing nut fastener. Background technique [0002] Though known public nut is of a great variety, purposes all is to fasten various objects together with bolt. In practice, the nuts are mostly installed on objects that are running or vibrating, and the nuts mounted on the objects are easy to loosen and fall off during the running or vibrating process. [0003] Chinese invention patent CN1587727A discloses a bearing nut, which is based on the principle of energy conversion and conservation law. A rolling element cover is designed between the nut and the fastening object, and a rolling groove is opened on the side plane of the nut to make the rolling element cover in When the object vibrates or moves, it slides and rubs against the rolling body in the rolling groove to generate heat, so that the vibration transmitted from the fastened object to the nut is converted into heat energy, preventi...
