Description
Technical field
The present invention relates to fastener more particularly to the locking means and its lock washer of a kind of nuts 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, under the nut face above plain washer, increase the frictional force between nuts and bolt, for preventing spiral shell
Mother loosens, and plays the role of preventing vibration from loosening, but often since by the outside tension of diameter, outer tension is produced derived from screw-down torque
It is raw to step up axle power, and opening packing phenomenon occurs, also often there is spring washer hydrogen embrittlement fracture, nut is by spring washer to flat
Apply that pressure is uneven and coefficient of friction very little between spring washer and nut, plain washer on washer, and occur 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, a kind of locking means of nuts and bolt are provided
And there is the packing that is not open, not broken, reinforcing uniformly, and coefficient of friction is big, most with nut, bolt and plain washer frictional contact surface
It is changing greatly, do 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 the lock washer and substitutes for rubber washer the spring washer of stainless steel or carbon steel, realizes nut
With 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 nuts and bolt is: passing through two quilts by the screw rod of existing bolt
Screw hole on fastener, then after putting on matched plain washer, then the upper rubber washer is covered on screw rod, nut is finally screwed on,
Compress, make rubber washer by nut, bolt and plain washer pretightning force be squeezed and deformed, be filled in the rubber washer, nut,
In the gap of bolt and plain washer between this, huge after being extruded because of the rubber washer, which returns, to be played expansive force and squeezes,
Increase the frictional force between this, and flexible fastening is integral, at this point, the nut, the plain washer and the spiral shell
Between the outer silk of bolt, there is the extruding force of interaction always by the rubber washer, is transmitted on the contact surface for screwing screw thread,
Make between four due to nut twist it is tighter, the contact surface screwed between screw thread between contact surface is bigger, and contact pressure is bigger, rubs
It is bigger to wipe power, any one in four will rotate, and require to overcome the frictional force screwed between screw thread, and huge between this
Big extruding force also always exists, and will not change because of the vibration by pretightning force between fastener and the bolt, and makes
There is retreat relaxation in nut, 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
Contact surface between deformed rubber washer and nut, bolt and plain washer, more than existing spring washer and nut, spiral shell
The big many of contact surface between bolt and plain washer.So the frictional force of lock washer of the present invention increases very much, it can only be tight
Firmware transverse vibration between plain washer and bolt, and be elastic locking between nuts and bolt, it will not loosen.The present invention
Structure is simple, easy to use, practical.

Specific embodiment
The locking means of nuts and bolt of the invention, that is, replace the spring generally used now with rubber washer 2
Washer.
In Fig. 1, the present invention includes bolt 1, nut 4, lock washer 2, plain washer 3, bolt 1 across by fastener first 5, quilt
The screw hole 10 of fastener second 6 will go up plain washer 3 by fastener 5, by set on the screw rod 11 of the bolt 1 after fastener 6 in exposing,
It covers upper rubber washer 2 on silk 7 outside the bolt of bolt 1 again, screws on the nut internal thread 9 of nut 4, tighten, because of the lock washer 2
Rubber washer 2 be extruded after huge return play expansive force and squeeze, and make bolt 1, rubber washer 2, nut 4 and plain washer
3, this is integral by 2 flexible fastening of rubber washer being squeezed and deformed, at this point, between this, the rubber that is deformed
The inner edge of rubber gasket 2 is filled with the gap 13 between nut 4, bolt 1, plain washer 3 and rubber washer, passes through the rubber washer
2 have the extruding force of interaction always, are transmitted to nut 4 and engage on the contact surface of screw thread with the spiral of bolt 1, and are in
On the contact surface of the outer silk 7 of the bolt in the gap 13 between this, make to screw screw thread since nut 4 is twisted tighter between four
Contact surface between pressure it is bigger, contact pressure is bigger, and friction moment is bigger, nut 4, bolt 1 and rubber washer 2,
Any one in this of plain washer 3 will rotate, and require to overcome the frictional force screwed between screw thread, and this is huge between four
Extruding force also always exist, although can because plain washer 3, bolt 1, by fastener first 5, by fastener second 6, bolt head 8 it
Between pretightning force vibration variation, and make by fastener first 5 and plain washer 3 and occurred between fastener second 6 and bolt head 8
Transverse rotation vibration, but not make that retreat relaxation occurs between nut 4 and bolt 1, even if in the case where strength shakes, due to flat
Washer 3 and small by the coefficient of friction between fastener first 5, and there is rotation vibration, but since the frictional force between four is very big,
Be not in separate, rotate between plain washer 3 and rubber washer 2, bolt 1, rubber washer 1 four, be more not in nut with
Loosening between bolt, regardless of by fastener first 5, by 6 transverse vibration of fastener second, elasticity is even always for nut 4 and bolt 1
It is connected together, even if being shaken by fastener first 5 by 6 axial impact of fastener second, rubber washer axial compression can only be made to thicken,
Thinning again, periodically elastic Axial changes are reversed without laterally unidirectional continuous rotation of the nut 4 on bolt 1, are loosened
Phenomenon, so that locking bolt 1 and nut 4, achieve the purpose that fine anti-loosing effect.
Above-mentioned rubber washer or lock washer, 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.
The present invention includes the lock washer of all rubber material matter with softer, elastic, is used for squeezing screw contact surface, and increases spiral shell
Silk contact surface and extruding force, thus increasing friction force, lock nut and bolt, here a just different citing.
