Description
Technical Field
The utility model relates to a nut especially relates to a flange face transverse groove cutting tire nut.
Background
The flange nut is different from a common nut in that the gasket and the nut are integrated, so that the surface area contact of the nut and a workpiece is increased, and compared with the combination of the common nut and a washer, the flange nut is firmer and has higher tension.
The vehicle tyre is in motion for a long time, and the nut on the tyre bears certain acceleration and vibration for a long time. At present, due to the fact that working environments of some engineering vehicles, trucks and the like are severe, impact vibration borne by tire nuts is large, and the situation that common tire nuts are loosened frequently occurs.
Some existing standard tire nuts do not add a specific anti-loosening solution to the vibration situation, and the anti-loosening capability of the tire nuts depends on the correct installation torque of the bolts. It is indeed possible to work safely under suitable installation conditions (precision installation tools, bolt coatings, lubricating oil, etc.). However, due to the fact that the use environments of vehicles are different and the operation conditions of maintenance personnel are limited, in the practical situation, a large number of tire nuts cannot be accurately installed, and the looseness prevention of the pretightening force introduced by the aid of the installation torque is not reliable. The company designs a novel nut aiming at the condition, and the looseness prevention is enhanced.

Detailed Description
Examples
The flange face transverse groove-cutting tire nut as shown in fig. 1 comprises a nut body 1, a flange ring 2 is formed at the bottom of the nut body 1, an oxidation anti-corrosion layer is arranged on the surface of the tire nut, the cross section of the nut body 1 is a regular hexagon, a transverse groove 3 is formed in the nut body 1, the depth of the transverse groove 3 is 11.09mm, the depth of the transverse groove 3 is 2/3 of the diameter of a circumscribed circle of the cross section of the nut body 1, the groove width of the transverse groove 3 is 0.8mm, and the distance between the bottom of the transverse groove 3 and the top of the nut body 1 is 2.8 mm; a first inner inclined plane 4 which inclines downwards is arranged on the inner side of the top surface of the nut body 1, and the angle between the first inner inclined plane 4 and the central axis of the nut body 1 is alpha =45 degrees; the outer side of the top surface of the nut body 1 is provided with an outer inclined surface 5 which is inclined downwards, and the angle between the outer inclined surface 5 and the top surface of the nut body 1 is beta =30 degrees; the two sides of the longitudinal section of the flange ring 2 are semicircular, the thickness of the flange ring 2 is 2mm, and the diameter of the flange ring 2 is 21.8 mm; the inner side of the bottom surface of the flange ring 2 is provided with a second inner inclined surface 6 which inclines upwards.
The depth of the transverse cutting groove 3 of the flange surface transverse cutting groove tyre screw can be 5.86-21.97 mm, the groove width towards the cutting groove 3 can be 0.5-1.2 mm, the distance between the bottom of the transverse cutting groove 3 and the top of the nut body 1 can be 1.5-5 mm, the angle between the first inner inclined plane 4 and the central axis of the nut body 1 can be alpha = 45-60 degrees, and the angle between the outer inclined plane 5 and the top surface of the nut body 1 can be beta = 15-30 degrees; the thickness of the flange ring 2 may be 1.5-2.5mm and the diameter of the flange ring 2 may be 11.8-42.8 mm. The depth of the transverse cut 3 needs to exceed the central axis of the nut body 1.
When the flange face transverse grooving tire nut is installed, the transverse groove is deformed through a press machine, so that the pitch of the inner thread grooving part of the upper half section tire nut is smaller than the pitch of the outer thread of the lower half part of the bolt. Because the thread pitch of the upper half part is changed, the corresponding external thread of the bolt needs to gradually expand the deformed internal thread and return the deformed internal thread to the original undeformed state, and the return deformation of the upper part of the nut generates a larger return elastic force to press on the bolt threads, so that a locking torque is generated between the nut and the bolt threads. The locking torque can keep the nut and the bolt relatively fixed.
The anti-loosening torque of the whole nut by introducing the transverse slot cutting structure is as follows:
M=Ma+Mp
wherein,
m: a total loosening prevention torque;
Ma: original anti-loosening torque;
Mp: increased anti-loosening torque;
after the transverse slot-cutting anti-loosening structure is added, under a static working condition, the total anti-loosening torque is increased, so that the loosening of the bolt needs larger external loosening torque and is greater than the total anti-loosening torque, and the anti-loosening effect of the tire nut is greatly enhanced.
Under the vibration working condition, the external vibration causes the anti-loosening moment M of the nutaDecrease or disappear, but MpBut still keeps unchanged, so that the total anti-loosening torque can still ensure that the bolt and the nut keep relatively static and cannot be loosened.
The gap generated by the transverse cutting groove enables the thread of the upper half part to be longitudinally pressed and deformed, so that a longitudinal thread pitch difference is generated, and the anti-loosening torque of the tire nut is kept by a longitudinal thread pitch difference structure. The utility model discloses a with the combination of original tire nut, promoted the application ability of this product at specific trade. The width of the transverse cutting groove has a very significant influence on the magnitude of the anti-loosening moment.
The above description of the examples is only intended to help understand the core ideas of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
