Description
Technical field
The present invention relates to assembly connection technical field of structures more particularly to a kind of anticreep connection structure and its installation methods.
Background technique
Threaded connection is the common connection type between two relatively independent component of machine, in the dress of component of machine
With in the process, in order to make to link together by screw thread pair, two component of machine connections are closer, and people use in engineering
Various tight connecting devices, kep nut 1 are exactly connection type common in the art, as shown in Figure 1 and Figure 2,
Kep nut 1 is made of 103 3 body part 101, fixed part 102 and tight lock part parts, fixed part 102 and tight lock part 103 two
Part is separately positioned on the outer peripheral surface of body part 101, and body part 101, fixed part 102 and the tight lock part 103 of kep nut 1 are
It is integrated forming, wherein prepsetting gap 104 is additionally provided between fixed part 102 and tight lock part 103, when by K-type spiral shell
After mother 1 is connected on mandrel 2 by screw thread pair, fixed part 102 and tight lock part 103 are connected to by using lock-screw 3
Together, lock-screw 3 passes through prepsetting gap 104, applies pretightning force appropriate by lock-screw 3, to make kep nut 1
Internal screw thread generate deformation, after but internal screw thread be fully engaged against in 2 external screw thread of mandrel, reached the mesh for preventing kep nut 1 from loosening
's.However, this connection type based on kep nut 1 has several disadvantages in that when in use
First is that since lock-screw 3 is axially disposed along kep nut 1, the coupling mechanism force applied by lock-screw 3
Direction be also it is axial along kep nut 1, according to the interaction relationship of power, fixed part 102 and tight lock part 103 are all born
From lock-screw 3 axial load, if axial load is larger or fixed part 102,103 thinner thickness of tight lock part,
Fixed part 102, tight lock part 103 will be destroyed, and therefore, the kep nut 1 applied in the prior art is 102 thickness of fixed part, pre-
If the ratio of 104 width of gap, 103 thickness of tight lock part is general are as follows: 6:1:3 is advisable, this proposes being manufactured for kep nut 1
Better requirement is gone out, difficulty of processing is big, and manufacturing cost is high.
Second is that the direction of the coupling mechanism force applied by lock-screw 3 is also, axial locking axial along kep nut 1
Power can only make the deformation of corresponding internal screw thread generation axially along on kep nut 1, and can not apply along its radial direction and make
Firmly, when the fit clearance between 1 body part 101 of kep nut and 2 external screw thread of mandrel is larger, axial lock clamp force is to K type spiral shell
The locking function and effect being cooperatively connected between mother 1 and mandrel 2 are poor, and the effect for preventing kep nut 1 from loosening is not achieved.
Third is that existing kep nut 1 is when in use, also elastomer can be loaded in prepsetting gap 104, pass through lock-screw
The 3 axial lock clamp forces applied compress the elastomer, achieve the purpose that preload, however, according to the interaction principle of power, bullet
Property body can also generate the reaction force contrary with axial lock clamp force, the reaction force while by axial lock clamp force
Act on fixed part 102, on tight lock part 103, counteract the partial deformation of fixed part 102, tight lock part 103, kep nut 1 with
The locking function and effect being cooperatively connected between mandrel 2 are deteriorated.
In conclusion it is existing insufficient in use in order to make up above-mentioned kep nut 1, in order to ensure screw thread pair connection knot
The locking of structure, there is an urgent need to design a kind of novel screw connection structure.
