Abstract
The present invention relates to field of mechanical technique, specifically flange nut, including flange nut ontology and flange nut internal screw thread, the tooth bottom of the flange nut internal screw thread of flange nut ontology is equipped with a tapered ramp, and the angle between the tapered ramp and the flange nut internal screw 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 screw thread tooth bottom, make bolt and when flange nut is mutually tightened, generate very big coupling mechanism force, avoids the problem of flange nuts of axle hub bearing pressed parts is easy to appear loosening；Phosphate coating is added respectively in flange nut interior threaded surface and tapered ramp surface, guarantees that the clamping force being threadedly coupled is stablized, and play the role of antirust.
Description
Technical field
The present invention relates to field of mechanical technique, specifically flange nut.
Background technique
With the development of car industry, the requirement to fastening parts of automobiles is higher and higher.Existing flange nut coupling mechanism force is insufficient,
Flange nut so as to cause axle hub bearing pressed parts is easy to appear loosening.Therefore, designing one kind can be improved locking
The flange nut equipped with variable-tooth type checknut of power is vital.
Summary 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 be improved 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 spiral shell in flange nut, including flange nut ontology and flange nut
Line, it is characterised in that: the tooth bottom of the flange nut internal screw thread of flange nut ontology is equipped with a tapered ramp, the wedge shape
Angle between inclined-plane and the flange nut internal screw thread lower plane reverse extending line is 30 °.
Angle between the flange nut internal screw 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 ontology is hexagonal flange formula flange nut, and the specification of hexagonal flange formula flange nut is M33
×1.5mm。
The flange nut ontology 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, in flange nut internal screw thread tooth bottom adds one 30 ° of tapered ramp, makes spiral shell
When bolt and flange nut are mutually tightened, very big coupling mechanism force is generated, the flange nut of axle hub bearing pressed parts is avoided
The problem of being easy to appear loosening；Phosphate coating is added respectively in flange nut interior threaded surface and tapered ramp surface, guarantees screw thread
The clamping force of connection is stablized, and plays the role of antirust.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is half sectional view of the invention.
Fig. 3 is flange nut internal screw thread cutaway view Amplified image of the invention.
Referring to figure 1, figure 2 and figure 3,1 is flange nut ontology；2 be flange nut internal screw thread；3 be tapered ramp.
Specific embodiment
The present invention is described further now in conjunction with attached drawing.
Referring to figure 1, figure 2 and figure 3, the present invention devises spiral shell in flange nut, including flange nut ontology and flange nut
Line.The 2 tooth bottom of flange nut internal screw thread of flange nut ontology 1 is equipped with a tapered ramp 3, tapered ramp 3 and flange nut
Angle between 2 lower plane reverse extending line of internal screw thread is 30 °.Folder between 2 lower plane of flange nut internal screw thread and upper plane
Angle is 60 °.2 surface of flange nut internal screw thread is equipped with phosphate coating, and 3 surface of tapered ramp is equipped with phosphate coating.Flange nut ontology 1 is
Specification is the hexagonal flange formula flange nut of 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 screw 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 screw 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 easy to appear pine
Dynamic problem；Phosphate coating is added respectively on 2 surface of flange nut internal screw thread and 3 surface of tapered ramp, guarantees the folder being threadedly coupled
Clamp force is stablized, and plays the role of antirust.
