Abstract
The present invention relates to field of mechanical technique, specifically a kind of flange nut equipped with variable-tooth type checknut, including flange nut body and flange nut internal thread, the tooth bottom of the flange nut internal thread of flange nut body is set there are one tapered ramp, and the angle between the tapered ramp and the flange nut internal thread lower plane reverse extending line is 30 °.The present invention is compared with the existing technology, one 30 ° of tapered ramp is added in flange nut internal thread tooth bottom, when so that bolt and the flange nut is mutually tightened, very big coupling mechanism force is generated, avoids the problem of flange nuts of axle hub bearing pressed parts is susceptible to loosening；Phosphate coating is added respectively in flange nut interior threaded surface and tapered ramp surface, is ensured that the clamping force being threadedly coupled is stablized, and is played the role of antirust.
Description
Technical field
The present invention relates to field of mechanical technique, specifically a kind of flange nut equipped with variable-tooth type checknut.
Background technology
With the development of car industry, the requirement to fastening parts of automobiles is higher and higher.Existing flange nut coupling mechanism force deficiency,
Flange nut so as to cause axle hub bearing pressed parts is susceptible to loosening.Therefore, design one kind can improve locking
The flange nut equipped with variable-tooth type checknut of power is vital.
The content of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide it is a kind of can improve coupling mechanism force be equipped with variable-tooth type
The flange nut of checknut.
In order to achieve the above object, the present invention devises a kind of flange nut equipped with variable-tooth type checknut, including convex
Edge nut body and flange nut internal thread, it is characterised in that：The tooth bottom of the flange nut internal thread of flange nut body is set
There are one tapered ramp, the angle between the tapered ramp and the flange nut internal thread lower plane reverse extending line
For 30 °.
Angle between the flange nut internal thread lower plane and upper plane is 60 °.
The flange nut interior threaded surface is equipped with phosphate coating.
The tapered ramp surface is equipped with phosphate coating.
The flange nut body is hexagonal flange formula flange nut, and the specification of hexagonal flange formula flange nut is M33
×1.5mm。
The flange nut body is hexagonal flange formula flange nut, and the specification of hexagonal flange formula flange nut is M33
×1.5mm。
The present invention compared with the existing technology, adds one 30 ° of tapered ramp in flange nut internal thread tooth bottom, makes spiral shell
When bolt is mutually tightened with flange nut, very big coupling mechanism force is generated, avoids the flange nut of axle hub bearing pressed parts
The problem of being susceptible to loosening；Phosphate coating is added respectively in flange nut interior threaded surface and tapered ramp surface, ensures screw thread
The clamping force of connection is stablized, and plays the role of antirust.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the half sectional view of the present invention.
Fig. 3 is the flange nut internal thread cutaway view Amplified image of the present invention.
Referring to Fig. 1, Fig. 2 and Fig. 3,1 is flange nut body；2 be flange nut internal thread；3 be tapered ramp.
Specific embodiment
The present invention is described further in conjunction with attached drawing.
Referring to Fig. 1, Fig. 2 and Fig. 3, the present invention devises a kind of flange nut equipped with variable-tooth type checknut, including convex
Edge nut body and flange nut internal thread.The 2 tooth bottom of flange nut internal thread of flange nut body 1 is set there are one wedge shape tiltedly
Face 3, the angle between 2 lower plane reverse extending line of tapered ramp 3 and flange nut internal thread is 30 °.Flange nut internal thread 2
Angle between lower plane and upper plane is 60 °.2 surface of flange nut internal thread is equipped with phosphate coating, and 3 surface of tapered ramp is equipped with
Phosphate coating.Flange nut body 1 is the hexagonal flange formula flange nut that specification is M33 × 1.5mm.
For the present invention when bolt is screwed into flange nut, the externally threaded cusp of bolt withstands on the wedge of flange nut internal thread 2
On shape inclined-plane 3, very big coupling mechanism force is generated, has achieved the purpose that prevent flange nut from loosening.
The present invention adds one 30 ° of tapered ramp 3 in the tooth bottom of flange nut internal thread 2, makes bolt and flanged nut
When parent phase is mutually tightened, very big coupling mechanism force is generated, the flange nut for avoiding axle hub bearing pressed parts is susceptible to pine
The problem of dynamic；Phosphate coating is added respectively on 2 surface of flange nut internal thread and 3 surface of tapered ramp, ensures the folder being threadedly coupled
Clamp force is stablized, and plays the role of antirust.
