Problems solved by technology

Although setting a self-tightening washer under the self-tightening nut reduces the risk of displacement and loosening of the fastening component to a certain extent, this method is only an additional layer of protection, that is, the effect achieved by self-tightening of two nuts is similar, and it still has greater potential for loosening and movement

Abstract

The invention discloses a bolt and nut fastening assembly, which belongs to the field of machinery and comprises a fastening nut body, a bolt and a washer. The contact surface between the fastening nut body and the washer is a spiral curved surface, and the spiral curved surface is formed by the A line connecting a point on the central axis of the fastening nut body and a point on the outer surface of the fastening nut body at the same height rotates at a constant speed around the central axis of the fastening nut body and moves along the axis of the fastening nut body at a constant speed. into, wherein the rotation angle is greater than 360° and less than 540°. The beneficial effects of the present invention are: the rotation angle of the spiral curved surface is set to be greater than 360°, and the radius is rotated more than one circle, thereby forming an embedded block on the contact surface between the fastening nut body and the washer, which is nested with the washer, so that even Part of the thread on the bolt is damaged due to vibration, and the washer and fastening nut body cannot move relative to each other in the axial direction of the bolt without being damaged, which really plays a role of self-tightening.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a bolt and nut fastening assembly. Background technique [0002] In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we will also find that in many cases, especially when they are applied to vibration, we often need to lock the already locked The structural parts are regularly repaired and reinforced to prevent structural dislocation caused by loose nuts and bolts. [0003] In view of the above situation, in actual operation, people use various methods to fasten the locked nuts and bolts, such as using super glue, electric welding, secondary reinforcement through perforation, etc., but there is still no way to fundamentally solve the problem of nuts and bolts. The phenomenon of loosening and shifting. [0004] For example, the publication number is CN106286558A invention patent discloses a self-tightening nut and ...
