Description
Technical field
The present invention relates to a kind of contraction nuts, especially by the new with anti-loose anti-theft function of internal thread tile wedge lock
Type shrinks nut, belongs to machinery field.
Background technology
It is well known that various machineries and equipments all be unable to do without threaded fastener when assembling, it is that mechanical industry must
Indispensable original basic part is referred to as " rice of industry ".But from being widely used before more than 200 years.Just have one
A inevitable weakness, i.e., can voluntarily loosen under strenuous vibration and alternate load effect, cause machine or equipment, facility not
Energy normal operation, gently then machine breakdown, heavy then casualties.
To solve the generation that threaded fastener causes the accident because loosening, from its birth, the science of countries in the world
Family, inventor and engineers and technicians, have just carried out a large amount of development test.They are using locking plate, pin, nylon inserts, change
The methods of gluing is learned to prevent nut from loosening.These innovations are the time for having delayed threaded fastener to loosen to a certain extent.
But it could not fundamentally solve the problems, such as that threaded fastener can loosen always.
Along with high ferro motor-car, heavy engineering vehicle and across river, steel structure bridge over strait Chinese and popularize all over the world.
Due to above equipment, facility, speed is fast, and impact is big, and the probability that threaded fastener thereon loosens is continuously increased, what accident occurred
Hidden danger also constantly exists.And the above-mentioned nut anti-looseness desorption method and measure that various countries scientific and technical personnel create are also helpless.
Therefore, nearly 20 for many years, by Japan, headed by the U.S., also Germany, France, Sweden, Britain and South Korea and depth
Ditch between fields enterprise holds its most newly developed locknut, campes to China one after another, and some comes into China
Field of track traffic, engineering machinery field, heavy-duty car field ... is to the industry penetration for needing high threads fastener.
The high ferro motor-car of one 16 section of marshalling, needs a stop nut more than 20,000.One across river, steel construction bridge over strait need it is high-end
Stop nut, few then hundreds of thousands part at most reach millions of, this is the great market share！China needs high-end performance
Stable stop nut, the world are also required to simple in structure, locking reliable new type nut.
The present inventor carries out threaded fastener deep for a long time theoretical research and practice analysis, bolt, nut fastener
With the use of when, be dynamic cooperation between screw pair, being formed in this way in bolts and nuts internal and external threads engagement place can not
The presence in the gap avoided, the gap is exactly the internal factor of nut loosening.The gap can be analyzed to axial gap and radial direction again
Gap, that is, normal gap when the locking measures such as plain washer, spring washer, binding nut or the double nut of generally use, can only disappear
Except axial gap therebetween, and radial clearance still remains, when external factor, that is, shock and vibration, difference variation or alternating load
Nut loosening is resulted in when acting on thereon, causes mechanical equipment, facility cisco unity malfunction, or even lead to a disaster.
Occupy absolute monopoly status in the application of Chinese high ferro motor-car threaded fastener at present is that the U.S. applies and firm must become
Thread form self-locking nut and Japanese Hadlock eccentric nut, common feature are all a cancellation the radial clearance in screw thread pair,
But apply must in the screw pair in jail in addition to the cusp of bolt will firmly be held out against on the inclined-plane at 30 ° of the tooth bottom of nut, the structure from
Rational mechanics angle analysis, decompose generation axial thrust load numerical value generated when common standard fastener is tightened axle power than
Much smaller, in order to reach the axle power of national standard defined, which will apply when tightening than common standard nut bigger
Installation torque, to generate defined axle power.Once it is by external impact, and bolt cusp is shaken with nut pitch bottom engagement place
De-, since the nut thread two sides do not contact with bolt thread both sides, axle power moment will drastically decline, therefore this is anti-
The stability of loose nut, reliability are unable to absolute guarantee.
In addition, Japanese its locking principle of Hadlock eccentric nut is identical to top locking principle as common double nut, only
Be common double nut it is axial to top along bolt, elimination is axial gap.But it is more quite a lot of with a plain nut than only, but
It is that its radial clearance can not still be eliminated after common double nut is tightened.It is locking since the common double nut radial clearance to top remains
Effect is nor most ideal.Although and Japan eccentric nut also belong to push up locking principle scope, its main feature is that bias make
With lower radial direction to top, due to fastening thread, its angle of thread is mostly 60 ° or 55 °, therefore using laterally to the side on top on the basis of bolt
Formula, than axial even better to the anti-loosing effect on top equally on the basis of bolt.But it is that eccentric nut exists except its deficiency
Each nut and the another side of bolt thread joint place are still with the presence of radial clearance when to top, therefore still cannot calculate very perfect.
In addition, at present the anti-theft nut that uses both at home and abroad it is numerous not less than dozens, mostly all non-dismountable, Bu Nengchong
It is multiple to use.The anti-theft nut that now widely used ball locking or rolling pin are locked in the market, it is not only non-dismountable, but also locking property
It can be also not so good.With supergrid, railway bridge is popularized, and the demand to the antitheft and locking fastener having both is urgent
It is badly in need of novel anti-loose anti-theft effect stability, novel fastener easy to loading and unloading in the market.
Invention content
A kind of contraction nut of the present invention, is made of the recessed nut of thickening hexagonal and the knurled nut with radial contraction function, should
It thickeies the recessed nut appearance and size of hexagonal and complies fully with 6170 standards of GB, only its total height is that GB 6170 adds with rule height of nut
The length of upper 2-3 times of same specification thread pitch, the knurled nut with radial contraction function, left end are fixed at least 3, and most 8
The big end of piece tile wedge, right end shape are corresponding regular polygon thin nut, oblique angle and the thickening recessed nut of hexagonal of the tile wedge
The oblique angle that the small hole wall of right output port imperial palace is formed is corresponding, and thickeies the recessed nut of hexagonal and the convex spiral shell with radial contraction function
The triangle internal thread of same specification is equipped in female and connected thereon tile wedge Inner arc.In addition, it is right to thicken the recessed nut of hexagonal
The oblique angle that imperial palace small hole wall in port is formed should be 0.25 degree to 1 degree more bigger than corresponding tile wedge oblique angle, has with compensation
The tile wedge of radial contraction function, at work when radial tightening, oblique angle gradually changes, and the recessed nut of thickening hexagonal
The length in right output port imperial palace stomatodeum hole is 3 times of same specification thread pitch and following.
And the tile wedge that knurled nut left end with radial contraction function is connected, shape like ancient houses roof becalm it is anti-
The arc-shaped tile of rain, and along gradually thicken wedge-shaped of its vertical section therefore be called tile wedge, oblique angle between 1 °~10 °,
When the tile wedge big end is connected in thin nut left end corresponding position, each tile wedge internal thread should surround same specification bolt helicla flute
Position is corresponding, and the longitudinal length of every tile wedge is 1.5 times~3 times of same specification nut thread screw pitch, and the tile wedge
When thin nut left end is connected, must not be adjacent between adjacent sheet and piece, should be there are gap, the arc radius Ying Yujia of the tile wedge
The taper hole that thick hexagonal recessed nut right end oblique angle is formed half is radial corresponding.
In addition, when being regular hexagon with the knurled nut of radial contraction function its right end thin nut shape, can be used for locking
The contraction nut of function when shape is non-regular hexagonal, configures corresponding with its shape non-regular hexagonal special spanner, then with
It thickeies the recessed nut of hexagonal and forms shrinkage type anti-theft nut.The knurled nut with radial contraction function, the connected tile wedge of left end
It is for adjusting its radial clearance between bolt, it is to control tile wedge in bolt that the right, which has the thin nut of 2-4 tooth internal threads,
The handling instrument of middle advance and retreat.
In summary：In practical applications, the recessed nut concave surface of hexagonal will be thickeied first to be tightened on bolt outwardly, makes its work
Make face and developed with the workpiece that need to be fastened, then tightened by the torque of national regulations with common torque spanner, generates suitable pre-tighten
Power.The nut has eliminated its axial gap between bolt at this time, then picks up left end with finger and be fixed with 3-8 piece tile wedges
, right end shape be regular hexagon thin nut, make its 3-8 piece tile wedge shape at frustum enter thicken the recessed nut right end of hexagonal
In the corresponding shrinkage pool in oblique angle, the thickening recessed nut of hexagonal must not pre-tighten at this time moves.Continue to turn shape to be regular hexagon
Thin nut when, the internal thread thread of its inner circumferential of each tile wedge have to be constantly radially normal direction tightening to bolt helicla flute, until
Until cooperation becomes interference fit therebetween, at this point, radial clearance is also eliminated between nut and bolt thread pair.Due to tile wedge
Big end be to be connected on thin nut left side, be motionless in contraction process.Only each tile wedge small end is in metallic elastic
Under effect, inner circumferential internal thread is gradually held tightly in bolt helicla flute, and usually gap is general between fastening thread bolts and nuts
It is not very big, therefore using the shrinkage pool oblique angle for thickening the recessed nut of hexagonal, it is 0.25 degree to 1 degree more bigger than tile wedge oblique angle, positive to use
Come compensate tile wedge shrink back bevel angles increase, so that it is affixed to shrinkage pool closer, therefore anti-loosing effect is also more preferable.
As for being uniformly connected on thin nut using minimum 3 most 8 tile wedges, be regarding nut nominal diameter size and
Fixed, nominal dimension smaller uses 3, when being applied on the big specification nut such as M60, should use 8 tile wedges.As for thickening
The recessed nut shrinkage pool of hexagonal is when being shunk under the numerical value, to the radially tightening point of bolt helicla flute using 1 ° to 10 ° with tile wedge oblique angle
Power is maximum.
Since axial gap and radial clearance are eliminated between nut and bolt in entire fastening system, coordinate therebetween
Become being interference fitted from loose fit, therefore anti-loosing effect is sufficiently stable reliable.
It is also very convenient to dismantle the contraction nut, as long as it is regular hexagon first reversely to turn shape with common wrench
Thin nut, you can the tile wedge for keeping its left end connected exits under the action of its internal thread from bolt helicla flute, and every watt
Piece wedge exits from the shrinkage pool for thickening the recessed nut of hexagonal under the action of metallic elastic, restores original oblique angle, until from bolt
It is unloaded in helicla flute.It is reversely turned with the spanner again and thickeies the recessed nut of hexagonal, so that it may very easily unload the recessed spiral shell of thickening hexagonal
It is female.
In addition, when the thin nut with contractile function its shape is non-regular hexagonal, it is identical as above-mentioned installation procedure, first
It is tightened with common torque spanner after thickening the recessed nut of hexagonal to required installation torque, then with shape is that non-regular hexagonal is corresponding
Special spanner tightens the left end that shape is corresponding non-regular hexagonal and is connected after the thin nut of tile wedge, so that it may lock this contraction
Nut.At this moment the thin nut is not first backed out reversely with the special spanner that shape is regular hexagon, and it is anti-with conventional torsion spanner
To back out thicken hexagonal recessed nut when, the shrinkage pool due to thickening the recessed nut of hexagonal is to be pressed on the convex spiral shell with radial contraction function
On the periphery of female left end tile wedge, only the more can move back the more tight until pull it is motionless until, to reach antitheft purpose.Such as to unload the receipts
Miniature anti-theft nut, as long as it is the convex with radial contraction function of non-regular hexagonal reversely to back out shape with special spanner first
