Abstract
The utility model discloses a kind of Anti-loosening nut, including nuts and bolt, it is characterised in that：The nut is deformation nut and locking nut, one end of the deformation nut is centrum, axial groove has been evenly distributed in this cone, one end of the locking nut is provided with the taper hole matched with the cone of the deformation nut, and the utility model has the remarkable advantage that anti-loosening effect is good and processing performance is good compared with prior art.
Description
Technical field
The utility model is related to a kind of screw connection structure, particularly a kind of Anti-loosening nut.
Background technology
It is that Japanese " breathing out moral Roc " Anti-loosening nut is combined to be influenceed in existing Anti-loosening nut technology larger, 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 matched with eccentric cone,
The anti-loosening principle of this nut combining structure is that eccentric cone deforms the body of bolt as chock wedging another nut bottom,
Increasing friction force, so as to realize anti-loosening purpose.The pressure area that this eccentric structure is produced is big, and the pressure of unit area is not
It is enough, anti-loosening effect under high-intensity oscillation or not ideal enough.
Also a kind of " combination of double thread eccentric nut ", its mechanism of action duplicates 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 the screw thread of female bottom of thread is increased, and it is produced interference fit with the screw thread of bolt, and increasing friction force is realized locking
Dynamic purpose.The major defect of this anti-loose structure is that rear thread is used for multiple times to damage and lose anti-loosening function.
Utility model content
The purpose of this utility model is to provide that a kind of anti-loosening effect is good and processing performance is good puts loose nut.
The technical solution of the utility model is, a kind of Anti-loosening nut, including nuts and bolt, it is characterised in that：It is described
Nut is deformation nut and locking nut, and one end of the deformation nut is centrum, and axial direction has been evenly distributed in this cone
Groove, one end of the locking nut is provided with the taper hole matched with the cone of the deformation nut.The cone of described locking nut one end
The taper in hole is 24 ° 26 ' 42, and " ± 30 ', the taper for deforming the cone of nut is 21 ° ± 30 '.The cone of described locking nut one end
, more than the taper of the cone of described deformation nut one end, the cone outside diameter of described deformation nut one end is more than institute for the taper in hole
The diameter at locking nut one end big end of taper hole is stated, the cone axial length of described deformation nut one end is less than the locking nut one
The axial length of the taper hole at end.
The utility model has the remarkable advantage that anti-loosening effect is good and processing performance is good compared with prior art.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model Anti-loosening nut.
Specific embodiment
The utility model in order to solve the defect of prior art presence, using structure as shown in Figure 1, the utility model with
The nut that bolt matches is double nut, that is, deform nut 1 and locking nut 4, and one end of the deformation nut is centrum 2, herein
Axial groove 3 is evenly distributed in cone, one end of the locking nut is provided with and the cone matching of the deformation nut
Taper hole 5.The taper for deforming the cone of nut determines that generally 21 °, tolerance is ± 30 ', the cone according to the nominal diameter of nut
The quantity and width of the uniform axial groove of body, the nominal diameter according to nut determine that generally 2-8 grooves, groove width is generally
0.5—3mm.Cone outside diameter is more than taper hole outside diameter, the length of the axial length less than taper hole of cone；In order to obtain more
The deflection of big deformation nut cone, the taper of the taper more than deformation nut cone of the taper hole of locking nut, generally 2-
5°。
Anti-loosening principle of the present utility model is that deformation nut is spun on bolt first, makes the hexahedron of deformation nut
End face is pressed on connected piece, and after having certain thrust, locking nut is spun on bolt, its taper hole is enclosed within deformation spiral shell
In female cone, and tighten, in rundown process, due to the taper of the taper more than cone of taper hole, the cone of nut is deformed first
The deformation of body small end is reduced, and the ridge of cone is pressed on the tooth of bolt, and is deformed forming powerful coupling mechanism force, together
When, due to the diameter of the cone big termination of the large port diameter less than deformation nut of locking nut taper hole, make the cone of deformation nut
Body is deformed inward from small end head to the entirety of big termination, and the cone segments whole ridge for deforming nut is pressed on the tooth of bolt simultaneously
It is deformed, forms coupling mechanism force, thus, coupling mechanism force of the present utility model has bigger coupling mechanism force compared with the prior art, prevents
Loosening ability is stronger, is particularly well-suited to the occasion of high-intensity oscillation condition, and such as high ferro train, railroad track fourth screw is paid, rail
Clamping plate screw is paid, the field such as vibrating machine, automobile, aero-engine, marine engine and vibratory equipment.
