Description
Technical field
The invention belongs to Anti-loosing connection parts field, more particularly, to the bolt used in vibrations, high speed rotation
Nut anti-looseness method.
Background technology
Bolt and nut connection belongs to most-often used detachable connection, but is being given a shock influence or high speed rotation
On axis in use, with the possibility for loosening, falling off.It should consider to prevent from loosening in the design for preventing bolt and nut, and not
The connection screw thread part that screw bolt and nut can be destroyed, the convenience for being provided simultaneously with repeatable dismounting, using.It is most on the market
All locking using rubbing, this mode is a kind of most widely used nut anti-looseness mode, and this mode generates between screw thread pair
One normal pressure not changed with external force, to generate the frictional force that screw thread pair can be prevented to relatively rotate.This normal pressure can lead to
It crosses axial or two is realized simultaneously to collet threaded pair.Such as use elastic washer, double nut, self-locking nut and the locking of nylon inserts
Nut etc..This nut anti-looseness mode is more convenient for the dismounting of nut, but the shock and vibration and varying load the case where, and one
Starting bolt can cause pretightning force to decline because of relaxation, and with the increase of vibration number, the pretightning force of loss slowly increases, finally
Nut will be caused to loosen, thread connection failure, either any nut anti-looseness method, although stop nut can solve very well
The problem of certainly nut is easy to loosen, if but do not pay attention to and maintain in use, periodic maintenance etc., stop nut is also because of it
Respective disadvantage and there are different problems.Therefore, then good nut nor put things right once and for all.
Invention content
In view of this, the invention is directed to a kind of bolt and nut anti-loose structure, keep anti-loosing effect more preferable, structure is steady
It is fixed reliable.
In order to achieve the above objectives, the technical solution of the invention is realized in：
A kind of bolt and nut anti-loose structure, including nut and the bolt that is connect with the nut thread, nut interior are provided with
Deformation original paper slot for accommodating flexible deformation original paper is provided with the locking screw for installation locking bolt on the end face of nut
Hole, a part for locking screw holes, which passes through, deforms original paper slot, and clamping screw being capable of crimp original after extending into locking screw holes inside
Part makes crimp original paper be abutted with bolt external screw thread.
Further, the quantity of locking screw holes is three on the nut, and is uniformly distributed around the axis of nut.
Further, after clamping screw screws in locking screw holes, the projection and deformation of clamping screw in the axial direction thereof
Original paper partly overlaps, when the body of clamping screw is protruded fully into locking screw holes, the close deformation in body end of clamping screw
The side wall of the nut end face for being arranged distant from clamping screw of original paper slot.
Further, it when deformation original paper is located in deformation original paper slot in the raw, deforms between original paper and bolt
There are gap, the deformation original paper is rubber ring or polyurethane circle.
Compared with the existing technology, a kind of hinged bolt nut shockproof structure described in the invention, it is easy to disassemble,
Disassembly process does not destroy bolt-nut connecting structure, ensures the secondary use of bolt and nut, spiral shell can be effectively prevent using frictional force
The vibrations of bolt nut fall off.
