Technical field
The invention belongs to industrial manufacturer's standard part---fastener areas, relate in particular to a kind of antivibration lock nut that can locate arbitrarily and can automatically enhancing self-locking strength when fastening.
Background technique
Nut, bolt are one of the most widely used connection of modern structure and machinery and fastening accessory.Though common nut, bolt all have self-locking performance in use, be subjected to the external force factor effect, change when big as vibration, impact, variable load and thermal stress, nut be prone to connecting of bolt looseningly, even can occur coming off.Nut loosening will cause and connect or the reducing even lose of fastening strength, thereby influence the quality of nut and Bolt Connection, cause each component of connection to damage prematurely, even cause equipment failure and personal safety accident.To the connection of component and fastening and locking aspect, people have done a large amount of useful work, and also exploring with keeping punching and studying, the technology and the measure of a lot of nut anti-looseness have been proposed, obtained gratifying effect, but locking safety reliability is also not ideal, the also more complicated that has on the structure, some makes cumbersome cost height, and the operation that has is not too convenient, therefore, also fundamentally do not solve the locking problem of nut at present.
Summary of the invention
The objective of the invention is at above-mentioned reason, provide a kind of antivibration locking safe and reliable, can locate arbitrarily, can the locating arbitrarily and antivibration lock nut that can automatically enhancing self-locking strength when fastening of simple in structure, easy manufacturing, easy to use, highly versatile.
To achieve these goals, the present invention is by the following technical solutions: the antivibration lock nut that can locate and can automatically enhancing self-locking strength when fastening of the present invention, comprise awl mouthful nut (a wherein end at nut two ends is that conical outwardly open nut is called the taper mouth nut, abbreviates awl mouthful nut as) and the elastic ring that is complementary with it.
Described awl mouthful nut is to be provided with a taper mouth at general nut towards bolt one end.Described taper mouth is outwards to form a taper shape from a described awl mouthful nut inner thread somewhere opening, and figuratively speaking, the shape of described taper mouth is outside tubaeform of opening, says that intuitively the section of described taper mouth has
Shape; Perhaps described awl mouthful nut is to be provided with a taper mouth at general nut towards bolt one end, and be provided with a circular baffle ring at the oral area of described taper mouth, described baffle ring is in order to block described elastic ring, so that no matter described elastic ring can both not leave described awl mouthful nut when off working state or working state, become as a whole with a described awl mouth nut.Say that intuitively the section that is provided with the described taper mouth of baffle ring has
Shape.This baffle ring can be affixed or affixed with other forms with screw engagement and described awl mouthful nut.The axial dimension of described taper mouth should be not more than half of described awl mouthful nut axial length, its radial dimension is to become big from the inside to the outside gradually, and its diameter should be greater than the diameter of thread of described awl mouthful nut, less than the distance (referring to the distance between the corresponding limit of polygonal) between the profile opposite side of described awl mouthful nut.The internal diameter of described baffle ring is at least greater than the minimum outer diameter of described elastic ring.
Described elastic ring is one and is complementary with described taper mouth that the side has the tapered collar of a breach.Described tapered collar external diameter vertically is ascending or descending continuous alternation, but internal diameter fixes, and internal diameter is at least greater than the diameter of the bolt that matches with it.Described elastic ring is an open loop circle, promptly has a breach in the side of described elastic ring circle is disconnected.The chord length of described elastic ring (girth deducts notch size), especially interior chord length should be less than the maximum perimeter of bolt thread, be squeezed in when reaching tightening state on the bolt by a described awl mouthful nut with the described elastic ring of box lunch, also exist a size greater than zero slit.The breach of described elastic ring can be straight, and is promptly parallel with the central axis of described elastic ring, also can be oblique, promptly spiral.
Corresponding to the described awl mouthful nut of no baffle ring, described elastic ring is one and is complementary with described taper mouth that the part that the side has a breach is that a tapered collar and a part are the composition rings of annulus.Described tapered collar external diameter vertically is ascending or descending continuous alternation, the external diameter of described annulus is fixed, the internal diameter of described tapered collar and described annulus is identical and fixes, and internal diameter is at least greater than the diameter of the bolt that matches with it.Described elastic ring is an open loop circle, promptly has a breach in the side of described elastic ring circle is disconnected.The chord length of described elastic ring (girth deducts notch size), especially interior chord length should be less than the maximum perimeter of bolt thread, be squeezed in when reaching tightening state on the bolt by a described awl mouthful nut with the described elastic ring of box lunch, also exist a size greater than zero slit.The breach of described elastic ring can be straight, and is promptly parallel with the central axis of described elastic ring, also can be oblique, promptly spiral.The advantage that baffle ring is set is that described awl mouthful nut and described elastic ring can be assembled into one whole before use, the convenient use, and a described awl mouthful nut moves back when unloading and moves back and unloads that the described elastic ring in back is difficult to be lost.But the area of contact of described elastic ring external conical shape face and described awl mouthful nut can reduce to some extent.
The interior outer side surface of described elastic ring can all be made smooth surface, or all makes the shape of threads surface; Or a side (inner side surface or outer side surface) makes smooth surface, and another side (outer side surface or inner side surface) makes the shape of threads surface.
When the outer side surface of described elastic ring was made shape of threads, the conical surface of described awl mouth nut also should be made shape of threads, and matched with the screw thread of described elastic ring outer side surface.When the inner side surface of described elastic ring is made shape of threads, should match with the bolt thread that matches with it.
Described elastic ring adopts the rubber-like material to make, and is squeezed in by a described awl mouth nut with the described elastic ring of box lunch and can not ftractures when reaching tightening state on the bolt, preferably still can recover its original shape after pine is unloaded.Above-mentioned elastic material comprises metal, nonmetal, organic and inorganic macromolecule material and composite material etc., as spring steel, plastics, rubber or other composite elastic materials.If described elastic ring is to adopt scleroid elastic material to make, so-called scleroid notion is meant that hardness is at least greater than described hardness of boring mouthful nut and bolt, soft, the rubber-like other materials of the preferably compound again quality of the interior outer side surface of described elastic ring.For example, do described elastic ring, then preferably outer side surface composite plastic, rubber, fiber or other alloys and nonmetallic material within it with spring steel.Compound quality is soft, the method for rubber-like material, can adopt interior outer side surface injection moulding at described elastic ring, is coated with elastic coating, method such as bonding.
The present invention can locate and the working principle of antivibration lock nut that can automatically enhancing self-locking strength when fastening is: because described awl mouthful nut with the relative position relation of described elastic ring before entering tightening state is: described elastic ring has at least a part to be placed on the outside of described taper mouth one end of described awl mouthful nut, and the described taper mouth of the inside of described awl mouth nut to have a part at least be empty.In fact, because elastic force effect, described elastic ring generally all is the oral area that as far as possible is in the described taper mouth of described awl mouthful nut during non-tightening state, and be attached on the tapered wall of described awl mouthful nut, and do not contact with bolt or slight the contact arranged with spiral shell, so when a described awl mouthful nut is screwed on the bolt supporting with it, the internal thread and the bolt thread of described awl mouthful nut begin engagement, before a described awl mouthful nut contacts fastened object, or more precisely be before described elastic ring closely contacts fastened object, mouthful nut is the same with plain nut just works by thread engagement for described awl, and described elastic ring does not contact with bolt or with bolt slight contacting arranged at this moment.When a described awl mouthful nut screw into the described elastic ring that is in outside its taper mouth and touches fastened object, described elastic ring will be subjected to certain extruding force, described elastic ring also will also can impose on this extruding force the tapered wall of described awl mouthful nut simultaneously toward the internal compression of described awl mouthful nut under the effect of extruding force.Along with constantly screwing of described awl mouthful nut, described elastic ring can be constantly toward described awl mouthful nut internal compression, the extruding force that described elastic ring is subjected to can be increasing, its extruding force that tapered wall of described awl mouthful nut is applied also can be increasing, simultaneously when described elastic ring is compressed, described elastic ring also can be constantly close to bolt, and can progressively apply extruding force to bolt, and the extruding force that applies also can be increasing.After described nut screwed, owing to the extruding force of described elastic ring to described awl mouthful nut, the thread engagement intensity of described awl mouth nut and bolt had obtained increase; Also owing to extruding force, described elastic ring can produce with described awl mouthful nuts and bolt simultaneously and closely contact, thereby has also strengthened described linking intensity of boring mouthful nut and bolt; Because the elasticity of described elastic ring self structure and the elasticity of described elastic ring self material and/or surfacing can produce the effect that absorbs or weaken to the ripple that shakes, and make a described awl mouthful nut have vibrationproof antivibration function.When a described awl mouthful nut pine is unloaded, make reducing of the extruding force that is subjected to along with described elastic ring, described elastic ring can be gradually expose outside from the taper mouth of described awl mouthful nut, and unclamps bolt gradually and get back to original state when idle.
If described elastic ring is blocked with instrument in the place that the described awl mouthful nut of needs stops, a described awl mouthful nut will be positioned at the position that sets securely.
From the above, the antivibration lock nut that can locate and can automatically enhancing self-locking strength when fastening of the present invention has antivibration and locating function, has when screwing automatically enhancing self-locking strength function, anti-loosening property is good, and highly versatile is easy to use, simple in structure, make easily.
