Abstract
The present invention relates to field of mechanical technique, specifically a kind of stop nut equipped with nylon inserts, including nut body and internal thread, the internal thread tooth bottom of nut body sets the tapered ramp there are one 30 °, nylon inserts is embedded at the top of nut body, nut body is hexagonal flange nut, and specification is M30 × 1.5mm, and nut body is mounted on the wheel hub installation position of bridge before vehicle bridge.The present invention compared with the existing technology, adds one 30 ° of tapered ramp, when bolts and nuts are mutually tightened, the cusp of bolt is just tightly withstood on the tapered ramp of variable-tooth type checknut, so as to generate very big coupling mechanism force in interior Bottom of Thread；Nylon inserts also is embedded in nut top, when bolts and nuts are mutually tightened, male thread voluntarily tap out on nylon inserts, and it is tightly wrapped up by nylon inserts, locking frictional force is increased, so as to play dual locking effect, solve thes problems, such as that axle hub loosens.
Description
Technical field
The present invention relates to field of mechanical technique, specifically a kind of stop nut equipped with nylon inserts.
Background technology
With the development of economy, car industry is more and more important, and application of the special fastener on automobile is also more and more extensive.
For heavy truck, Medium Truck, light truck and motor bus when vehicle bridge are in connection fastening, it may occur that axle hub loosens
Situation, this is because the relaxing serializability of fastener is poor, enough coupling mechanism forces can not be provided.
The stop nut big therefore, it is necessary to design a kind of coupling mechanism force.
The content of the invention
The stop nut big the purpose of the present invention is having overcome the deficiencies of the prior art and provide a kind of coupling mechanism force.
In order to achieve the above object, the present invention is a kind of stop nut equipped with nylon inserts, including nut body and interior
Screw thread, it is characterised in that：The internal thread tooth bottom of nut body is set there are one tapered ramp, the tapered ramp with it is described
Angle between internal thread lower plane reverse extending line is 30 °, nylon inserts is embedded at the top of nut body, nut body is
Hexagonal flange nut, specification are M30 × 1.5mm, and nut body is mounted on the wheel hub installation position of bridge before vehicle bridge.
Angle between the internal thread lower plane and upper plane is 60 °.
The interior threaded surface is equipped with phosphate coating.
The tapered ramp surface is equipped with phosphate coating.
The nylon inserts is wrapped in the end of bolt.
The nylon inserts is sheet of nylon.
The present invention compared with the existing technology, adds one 30 ° of tapered ramp, when bolts and nuts phase in interior Bottom of Thread
When mutually tightening, the cusp of bolt is just tightly withstood on the tapered ramp of variable-tooth type checknut, so as to generate very big lock
Clamp force；Also be embedded with nylon inserts in nut top, when bolts and nuts are mutually tightened, male thread on nylon inserts voluntarily
Tap out, and tightly wrapped up by nylon inserts, locking frictional force is increased, so as to play dual locking effect, is effectively solved
The problem that axle hub of having determined loosens.
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 helicitic texture schematic diagram of the present invention.
Referring to Fig. 1-Fig. 3,1 is nut body；2 be internal thread；3 be tapered ramp；4 be nylon inserts.
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 is a kind of stop nut equipped with nylon inserts, including nut body and interior
Screw thread.The 2 tooth bottom of internal thread of nut body 1 is set there are one tapered ramp 3, the tapered ramp 3 and the internal thread 2
Angle between lower plane reverse extending line is 30 °, and the top of nut body 1 is embedded with nylon inserts 4, and nut body 1 is six
Angle flange nut, specification are M30 × 1.5mm, and nut body 1 is mounted on the wheel hub installation position of bridge before vehicle bridge.Due to nut sheet
Body 1 is hexagonal opposite side form, ensure that the installation capability and dynamic balance performance of nut body 1, easy for installation.
Arrow shown in Fig. 3 is screw-in direction.
In the present invention, the angle between 2 lower plane of internal thread and upper plane is 60 °.
2 surface of internal thread is equipped with phosphate coating, and 3 surface of tapered ramp is equipped with phosphate coating, and torque coefficient is stablized, ensure that and pressed from both sides
The staring torque that mandrel is held, ensure that comprehensive performance and antirust ability.
Nylon inserts 4 is wrapped in the end of bolt.
The present invention adds one 30 ° of tapered ramp 3 at 2 tooth bottom of internal thread, when bolts and nuts body 1 is mutually tightened
When, the cusp of bolt is just tightly withstood on the tapered ramp 3 of variable-tooth type checknut, so as to generate very big coupling mechanism force；
Nylon inserts 4 also is embedded at 1 top of nut body, when bolts and nuts body 1 is mutually tightened, male thread is in nylon inserts
Voluntarily tap out, and tightly being wrapped up by nylon inserts 4, increases locking frictional force on 4, so as to play dual locking effect
Fruit solve thes problems, such as that axle hub loosens.
