Abstract
The present invention relates to field of mechanical technique, specifically a kind of slotted round nut equipped with variable-tooth type checknut, including slotted round nut body and slotted round nut internal thread, the tooth bottom of the slotted round nut internal thread of slotted round nut body is set there are one tapered ramp, and the angle between the tapered ramp and the slotted round 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 slotted round nut internal thread tooth bottom, when so that bolt and the slotted round nut is mutually tightened, very big coupling mechanism force is generated, avoids the problem of slotted round nuts of axle hub bearing pressed parts is susceptible to loosening；Phosphate coating is added respectively in slotted round 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 slotted round 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 slotted round nut coupling mechanism force is not
Foot, the slotted round nut so as to cause axle hub bearing pressed parts are susceptible to loosening.Therefore, design one kind can improve
The slotted round nut equipped with variable-tooth type checknut of coupling mechanism force 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 slotted round nut of checknut.
In order to achieve the above object, the present invention devises a kind of slotted round nut equipped with variable-tooth type checknut, including
Slotted round nut body and slotted round nut internal thread, it is characterised in that：The slotted round nut internal thread of slotted round nut body
Tooth bottom set there are one tapered ramp, the tapered ramp and the slotted round nut internal thread lower plane reverse extending
Angle between line is 30 °.
Angle between the slotted round nut internal thread lower plane and upper plane is 60 °.
The slotted round nut interior threaded surface is equipped with phosphate coating.
The tapered ramp surface is equipped with phosphate coating.
The specification of the slotted round nut body is M60 × 1.5mm.
The specification of the slotted round nut body is M60 × 1.5mm.
The present invention compared with the existing technology, adds one 30 ° of tapered ramp in slotted round nut internal thread tooth bottom, makes
When bolt is mutually tightened with slotted round nut, very big coupling mechanism force is generated, avoids the fluting of axle hub bearing pressed parts
Round nut is susceptible to the problem of loosening；Phosphate coating is added respectively in slotted round nut interior threaded surface and tapered ramp surface,
Ensure that the clamping force being threadedly coupled is stablized, and play the role of antirust.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the sectional view of the present invention.
Fig. 3 is the slotted round nut internal thread cutaway view Amplified image of the present invention.
Referring to Fig. 1, Fig. 2 and Fig. 3,1 is slotted round nut body；2 be slotted round 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 slotted round nut equipped with variable-tooth type checknut, including
Slotted round nut body and slotted round nut internal thread.The tooth bottom of the slotted round nut internal thread 2 of slotted round nut body 1 is set
There are one tapered ramp 3, the angle between 2 lower plane reverse extending line of tapered ramp 3 and slotted round nut internal thread is 30 °.
Angle between 2 lower plane of slotted round nut internal thread and upper plane is 60 °.2 surface of slotted round nut internal thread is equipped with phosphatization
Layer, 3 surface of tapered ramp are equipped with phosphate coating.Slotted round nut body 1 is the slotted round nut that specification is M60 × 1.5mm.
For the present invention when bolt is screwed into slotted round nut, the externally threaded cusp of bolt withstands on slotted round nut internal thread 2
Tapered ramp 3 on, generate very big coupling mechanism force, achieved the purpose that prevent slotted round nut from loosening.
The present invention adds one 30 ° of tapered ramp 3 in 2 tooth bottom of slotted round nut internal thread, and bolt is made to justify with fluting
When nut is mutually tightened, very big coupling mechanism force is generated, the slotted round nut for avoiding axle hub bearing pressed parts easily goes out
The problem of now loosening；It adds phosphate coating respectively on 2 surface of slotted round nut internal thread and 3 surface of tapered ramp, ensures that screw thread connects
The clamping force connect is stablized, and plays the role of antirust.
