Abstract
The invention discloses a kind of Anti-loosening nut, including nuts and bolt it is characterised in that：Described nut is deformation nut and locking nut, one end of described deformation nut is vertebral body, this cone has been evenly distributed axial groove, one end of described locking nut is provided with the taper hole matching with the described cone deforming nut, and the present invention has the remarkable advantage that anti-loosening effect is good and processing performance is good compared with prior art.
Description
Technical field
The present invention relates to a kind of screw connection structure, particularly a kind of Anti-loosening nut.
Background technology
Affecting larger in existing Anti-loosening nut technology is Japanese " breathing out moral Roc " Anti-loosening nut combination, its knot
Structure is that the cone of a bias is arranged at the top of a nut, and one end of another nut is provided with the taper hole matching with eccentric cone,
The anti-loosening principle of this nut combinative structure is that eccentric cone wedges another nut bottom as chock, so that the body of bolt is deformed,
Increasing friction force, thus realize anti-loosening purpose.The pressure area that this eccentric structure produces is big, and the pressure of unit area is not
Enough, the anti-loosening effect under high-intensity oscillation or not ideal enough.
Also have a kind of " combination of double thread eccentric nut ", its mechanism of action is duplicated with " breathing out moral Roc " nut.
There is " applying must be firm " the high accuracy Anti-loosening nut in Shanghai again, its structure one is to improve the precision of screw thread, and two is in spiral shell
The angle of female screw thread of the bottom of thread increases so as to produce interference fit with the screw thread of bolt, increasing friction force is realized locking
Dynamic purpose.The major defect of this anti-loose structure is rear thread to be used for multiple times and damages and lose anti-loosening function.
Content of the invention
It is an object of the invention to provide a kind of anti-loosening effect is good and processing performance is good puts loose nut.
The technical scheme is that, a kind of Anti-loosening nut, including nuts and bolt it is characterised in that：Described nut
For deformation nut and locking nut, one end of described deformation nut is vertebral body, has been evenly distributed axial groove, institute in this cone
The one end stating locking nut is provided with the taper hole matching with the described cone deforming nut.The cone of the taper hole of described locking nut one end
Spend for 24 ° 26 ' 42 " ± 30 ', deformation nut cone taper be 21 ° ± 30 '.The cone of the taper hole of described locking nut one end
The taper of the cone more than described deformation nut one end for the degree, the cone outside diameter of described deformation nut one end is more than described locking
The diameter at the big end of nut one end taper hole, the cone axial length of described deformation nut one end is less than the cone of described locking nut one end
The axial length in hole.
The present invention has the remarkable advantage that anti-loosening effect is good and processing performance is good compared with prior art.
Brief description
Fig. 1 is the structural representation of Anti-loosening nut of the present invention.
Specific embodiment
In order to solve the defect of prior art presence, using structure as shown in Figure 1, present invention's present invention is matched with bolt
Nut be double nut, i.e. deformation nut 1 and locking nut 4, one end of described deformation nut is vertebral body 2, edge in this cone
Circumference is evenly equipped with axial groove 3, and one end of described locking nut is provided with the taper hole 5 matching with the described cone deforming nut.Become
The taper of the cone of shape nut determines according to the nominal diameter of nut, generally 21 °, and tolerance is ± 30 ', and described cone is uniform
The quantity of axial groove and width, the nominal diameter according to nut determines, generally 28 grooves, and groove width is generally 0.5 3mm.
Cone outside diameter is more than taper hole outside diameter, and the axial length of cone is less than the length of taper hole；In order to obtain bigger deformation
The deflection of nut cone, the taper of the taper hole of locking nut is more than the taper of deformation nut cone, generally 2-5 °.
The anti-loosening principle of the present invention is first deformation nut to be spun on bolt, make the hexahedron end face of deformation nut
It is pressed on connected piece, and after having certain thrust, locking nut is spun on bolt so as to taper hole is enclosed within deformation nut
In cone, and tighten, in rundown process, because the taper of taper hole is more than the taper of cone, the cone of deformation nut first is little
End deformation is reduced, and the ridge of cone is pressed on the tooth of bolt, and is deformed forming powerful coupling mechanism force, meanwhile, by
In locking nut taper hole large port diameter be less than deformation nut the big termination of cone diameter, make the cone of deformation nut from childhood
The entirety of termination to big termination is deformed inward, and the whole ridge of cone segments of deformation nut is pressed on the tooth of bolt and produces change
Shape, forms coupling mechanism force, thus, the coupling mechanism force of the present invention has bigger coupling mechanism force compared with the prior art, and locking kinetic force is more
By force, it is particularly well-suited to the occasion of high-intensity oscillation condition, such as high ferro train, railroad track fourth screw are paid, and railways splint screw is paid,
The fields such as vibrating machine, automobile, aero-engine, marine engine and vibratory equipment.
