Using the beneficial effect of above-mentioned technical proposal：The nut body of the stop nut, form thread center's line of nut
It it is 0.5~10 ° with the misaligned angle of nut body center line.Big footpath, central diameter and the path of the internal thread of the nut body with
Corresponding state indicates 0.01~1mm reduction, it is therefore an objective to it is fitted close between nut thread and bolt thread.The stop nut
Bottom make the design of special flange, bottom outer is designed with planar annular, within the nut of different size unlike material is designed with
Circle is the taper bottom surface that starting point angle of inclination is 0.3~6 °.The structure of flange flange can increase nut body end radial force
Intensity, the problem of avoiding nut body end thread from being tightly engaged because of stress deformation and bolt thread when tightening.
During stop nut is tightened, nut is using initial contact point as fulcrum, using the engagement of helix of thread as guiding,
During different size nut is by the torsional forces pretension of national standard, circumferential plane and the workpiece faying face of nut flange bottom outer connect
Fitting is touched, now two sections of cambered surfaces screw thread radial clearance symmetrical above and below of nut and bolt, disappears under thread center's line tilting action
Remove and engage zero-clearance, add the radial force of nut two sections of cambered surface screw threads symmetrical above and below and axial load, and then decomposed spiral shell
Normal direction axle power when female vibrated, while add between screw bolt and nut screw thread pays, screw thread cambered surface symmetrical above and below tightly engages mutually
The frictional force of lock, it can prevent nut from moving back loosening because vibrating, impacting rotation.
After the circumferential plane of stop nut flange base outer contacts fitting with workpiece faying face, in the torsion of national regulations
Continue pretension under square power, pretightning force makes the strong malleable stress expansion in the wrong of the nut flange bottom conical surface be pasted completely with workpiece faying face
Close, form the lifting tension force that nut keeps nature normal direction, increase nut and the elastic pre-tight stress of bolt axial direction, secure component exist
In the case of vibration, impact, dynamic loading fluctuation, the strong malleable stress in the wrong of the stop nut remains in that the axial pretightening of nut
Power is constant, can prevent nut loosening rotation from moving back.
