Abstract
The invention discloses a kind of difference ratchet type blocking double nuts, it is made of top nut and lower nut, top nut, lower nut are equipped with ratchet, and top nut, lower nut ratchet the number of teeth it is not identical, top nut, lower nut one lesser angle of every relative rotation, just there is one group of ratchet engagement, effectively prevents the opposite loosening between double nut, overcome the locking disadvantage of traditional double nut frictionally.
Description
Technical field
The present invention relates to a kind of stop nut more particularly to a kind of follow-on double nuts.
Background technique
Nut is widely used, and in some vibrations or important occasion, needs using loosing Prevention Technology, pairs of anti-loose nut be by
Widely applied technology, but in occasion some more important or that vibration is strong, common double nut still cannot reach satisfied
Anti-loosing effect.There are many improved double nut technologies in the prior art, such as have the double nut of eccentric bushing, have tightening structure
Double nut, principle substantially by increase frictional force it is locking, though increasing anti-loosing effect, but still cannot prevent between double nut
Relative rotation, and have that structure is complicated, processing difficulties, it is higher to screw rod required precision joined together the disadvantages of.
Summary of the invention
The object of the present invention is to provide a kind of difference ratchet type blocking double nuts, using ratchet structure, effectively prevent double spiral shells
Rotating backward between mother relatively, greatly improves the anti-loosing effect of double nut.
To achieve the above object, technical scheme is as follows: difference ratchet type blocking double nut, including top nut and
Lower nut, the top nut, lower nut are equipped with ratchet, and top nut, lower nut ratchet the number of teeth it is not identical.Top nut,
As soon as the lesser angle of the every relative rotation of lower nut has one group of ratchet engagement, the opposite loosening between double nut is effectively prevented,
Overcome the locking disadvantage of traditional double nut frictionally.The top nut, lower nut ratchet be located on the end face of nut
Or on periphery or on circular conical surface；The screw thread of the ratchet position and nut of the top nut or lower nut can be for one heart or partially
The heart；The top nut, the number of teeth of the ratchet of lower nut, tooth form, the facewidth, tooth height can according to the size of nut, intensity, install and use
It is required that etc. selections be reasonably worth.When installation, lower nut is first tightened, then screw on nut, the later period is tightened in top nut, has one group of ratchet to open
Beginning stress simultaneously causes resistance to top nut is tightened, and further increases screw-down torque, due to the presence of nut and bolt flexible deformation,
One group of ratchet will be had to cross and engage, as soon as every rotation specific angle, will have another group of ratchet and cross and engage, directly
Reach the Tightening moment of setting.Because of the effect of ratchet structure, top nut is just difficult after tightening to retract, in vibration processes, upper,
Lower nut is combined together always, to reach a lasting anti-loosing effect.When disassembly, preferably upper lower nut is dismantled simultaneously,
Top nut can also first be torn open, top nut at this time will drive lower nut to rotate together by ratchet.
Beneficial effects of the present invention:
1. difference ratchet type blocking double nut of the invention can effectively prevent anti-between double nut using ratchet structure
To rotation, the locking disadvantage of traditional double nut frictionally is overcome, the anti-loosing effect of double nut is greatly improved.
2. the ratchet quantity of difference ratchet type blocking double nut of the invention, upper lower nut is different, it is equivalent to and improves spine
The indexing quantity of tooth, top nut one lesser angle of every rotation, can be achieved with the engagement of one group of ratchet of top nut and lower nut.
3. the ratchet quantity of difference ratchet type blocking double nut of the invention, upper lower nut is different, during the installation process, respectively
Ratchet replaces stress, and installation process is relatively easy.
Detailed description of the invention
Fig. 1 is 1 top nut of embodiment, lower nut schematic diagram；
Fig. 2 is 2 top nut of embodiment, lower nut schematic diagram；
Fig. 3 is 3 top nut of embodiment, lower nut schematic diagram；
Referring to Fig. 1: 1- top nut, 2- lower nut, 3- ratchet,
Specific embodiment
Embodiment 1:
As shown in Figure 1, top nut is equipped with 7 ratchets by taking M30 nut as an example, lower nut is equipped with 8 ratchets, and ratchet is located at
On the end face of nut, the ratchet of top nut is located at lower end surface, and the ratchet of lower nut is located at upper surface, and each ratchet is in circumferencial direction
It occupies less than 1/56th circumference, tooth high about 1mm, the facewidth about 3mm, tooth top have fillet, the ratchet side of upper and lower nut
To be easy to screw, it is difficult to unscrew.When installation, lower nut is first tightened, then screw on nut, when top nut and lower nut end face contact
When, there is one group of ratchet to start stress and cause resistance to top nut is tightened, screw-down torque is further increased, due to nut and bolt
The presence of flexible deformation, this group of ratchet mutually can be crossed and be engaged, as soon as 56/circumference of every rotation, will have another
Group ratchet is crossed and is engaged, the Tightening moment until reaching setting.Because of the effect of ratchet structure, top nut is difficult to after tightening
It retracts, in vibration processes, upper and lower nut is combined together always, to reach a lasting anti-loosing effect.
Embodiment 2:
As shown in Fig. 2, the ratchet of upper and lower nut is located on the periphery of nut, remaining is the same as embodiment 1.The embodiment spine
Tooth is located on the periphery of nut, and ratchet is not influenced by extruding force huge between two nuts, by the bullet of nut radial direction when installation
Property deformation to realize mutually crossing and engaging for ratchet, overcome ratchet in embodiment 1 and be easy to be extruded damage in an installation
Disadvantage, the disadvantage is that manufacture difficulty is greater than embodiment 1.
Embodiment 3:
As shown in figure 3, the ratchet of upper and lower nut is located on the circular conical surface of nut, remaining is the same as embodiment 1.The embodiment spine
Tooth is located at meeting on the circular conical surface of nut, and nut is radial when installation and axial flexible deformation can realize mutually crossing for ratchet simultaneously
And engage, take into account the advantage and disadvantage of embodiment 1 and embodiment 2.
The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention is any
The equivalent changes and modifications that those skilled in the art is made under the premise of not departing from present inventive concept and principle should all belong to
In the scope of protection of the invention.
Top nut of the present invention, lower nut are not the nut for refering in particular to install up and down, are for ease of description.
