Description
Technical field
The present invention relates to fastener more particularly to the locking means and its lock washer of a kind of nut and bolt.
Background technique
Often with spring washer come lock nut and bolt, spring washer generally has stainless steel and carbon steel present people
Inc screw washer, face increases the frictional force between nut and bolt, by the upper surface of fastener for preventing under the nut
Only nut loosening plays the role of preventing vibration from loosening, but often since by the outside tension of diameter, outer tension is derived from screwing force
What square generated steps up axle power, and opening packing phenomenon occurs, and spring washer hydrogen embrittlement fracture also often occurs, nut passes through spring washer
To applied that pressure is uneven in fastener first and spring washer and nut, by the coefficient of friction very little between fastener first,
And there is vibration, rotation, relaxation.
Summary of the invention
It is an object of the invention to overcome it is above in the prior art the shortcomings that, the locking means of a kind of nut and bolt are provided
And there is the packing that is not open, not broken, reinforcing uniformly, and coefficient of friction is big, with nut, bolt and by fastener first CONTACT WITH FRICTION
Face is maximized, does not occur vibration rotation relaxation, lock washer for lock nut and bolt.
The present invention is achieved through the following technical solutions:
The present invention uses lock washer and substitutes for rubber washer the spring washer of stainless steel or carbon steel, realizes nut and spiral shell
The preload and locking of bolt.
The rubber washer section be two oval in T shape or round or oval or rectangles or circle+rectangle or
The soft rubber circle of the O shape band elasticity of one of ellipse+rectangle or the combination in T shape of two rectangles.
The present invention realizes that the working principle of the locking means of nut and bolt is: passing through two quilts by the screw rod of existing bolt
Screw hole on fastener covers the upper rubber washer on the screw rod of exposing, finally screws on nut, compresses, make rubber washer quilt
It nut, bolt and is squeezed and deformed by the pretightning force of fastener first, is filled in the rubber washer, nut, bolt and tight
In gap of the firmware first between this, huge after being extruded because of the rubber washer, which returns, to be played expansive force and squeezes, and makes this
Between frictional force increase, and flexible fastening is integral, at this point, the nut, it is described by fastener first and the bolt outside
Between silk, there is the extruding force of interaction always by the rubber washer, be transmitted on the contact surface for screwing screw thread, make four
Between person due to nut twist it is tighter, the contact surface screwed between screw thread between contact surface is bigger, and contact pressure is bigger, frictional force
Bigger, any one in four will rotate, and require to overcome the frictional force screwed between screw thread, and huge between this
Extruding force also always exists, and will not change because of the vibration by pretightning force between fastener second and the bolt, and makes spiral shell
There is retreat relaxation in mother, thus lock nut and bolt.
Lock washer of the present invention, the spring pad that alternative existing people generally use, application method is very simple, no
Narration, and can repeated disassembled and assembled use.
Compared with existing spring washer, due to making lock washer exist present invention employs the O shape structure rubber washer of closure
In approximately the same plane, so power transmission is uniform；Due to using soft rubber material, so being not in hydrogen embrittlement fracture；Due to adopting
It is more much higher than the coefficient of friction between steel spring pad and steel with the coefficient of friction between rubber and steel；Again due to squeezing
Deformed rubber washer and nut, bolt and by the contact surface between fastener first, more than existing spring washer and nut,
Bolt and by the big many of contact surface between fastener first.So the frictional force of lock washer of the present invention increases very much, it can only
It is by fastener second by transverse vibration between fastener first and bolt, and between nut and bolt is elastic locking, it will not
It loosens.Present invention eliminates plain cushion coil structures are simpler, using more convenient, practical.

Specific embodiment
The locking means of nut and bolt of the invention, that is, replace the spring generally used now with rubber washer 2
Washer, and eliminate plain washer.
In Fig. 1, the present invention include bolt 1, nut 4, lock washer 2, bolt 1 pass through by fastener first 5, by fastener second
6 screw hole 10 will expose by fastener 5, by the upper rubber pad of set on silk 7 outside the bolt of the screw rod 11 of the bolt 1 after fastener 6
Circle 2, screws on the nut internal thread 9 of nut 4, tightens, huge after being extruded because of the rubber washer 2 of the lock washer 2 return play it is swollen
Expansive force squeezes, and makes bolt 1, rubber washer 2, nut 4 and by fastener first 5, this passes through the rubber pad that is squeezed and deformed
It is integral to enclose 2 flexible fastenings, at this point, between four, the inner edge for the rubber washer 2 being deformed be filled with nut 4, bolt 1,
By the gap 12 between fastener first 5 and rubber washer 2, there is the extruding of interaction always by the rubber washer 2
Power is transmitted to nut 4 and engages on the contact surface of screw thread with the spiral of bolt 1, and the spiral shell in the gap 12 between this
On the contact surface of the outer silk 7 of bolt, making since nut 4 is twisted tighter between four, the pressure screwed between the contact surface of screw thread is bigger,
Contact pressure is bigger, and moment of friction is bigger, nut 4, bolt 1 and rubber washer 2, any in this by fastener first 5
One will rotate, and require to overcome the frictional force screwed between screw thread, and this huge extruding force also always exists between four,
Although can change because of bolt 1, by fastener first 5, by the vibration of pretightning force between fastener second 6, bolt head 8, and make tight
Firmware first 5 is occurred transverse rotation vibration, but not makes to occur between nut 4 and bolt 1 between fastener second 6 and bolt head 8
Relaxation is retreated, even if in the case where strength shakes, due to small by fastener first 5 and by the coefficient of friction between fastener second 6, and
There is rotation vibration, but is not in by fastener first 5 and rubber washer 2, spiral shell since the frictional force between above four is very big
It separates, rotate between bolt 1, rubber washer 1 four, be more not in the loosening between nut 4 and bolt 1, regardless of by fastener
First 5, by fastener second 6 how transverse vibration, nut 4 is resiliently connected together always with bolt 1, though by fastener first 5, quilt
The vibration of 6 axial impact of fastener second can only make the axial compression of rubber washer 2 thicken, then thinning, periodically elasticity Axial changes,
It is reversed without laterally unidirectional continuous rotation of the nut 4 on bolt 1, loose phenomenon, thus locking bolt 1 and nut 4,
Achieve the purpose that fine anti-loosing effect.
Above-mentioned rubber washer 2 or lock washer 2, material is preferably water-fast, pressure-resistant, heatproof, oil resistant, corrosion resistant,
Gas permeability is low, coefficient of friction is big, the restorative good rubber of softer, elastic be made, such as nitrile rubber, fluorubber, silicon rubber
Deng.The present invention includes the lock washer of all rubber material matter with softer, elastic, is used for squeezing screw contact surface, and is increased
Screw contact surface and extruding force, thus increasing friction force, lock nut and bolt, here a just different citing.
