Lock Nut
The lock nut is a nut widely used in machinery and other industries. Its working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced in dynamic loads. In some important occasions, we will take some anti-loose measures to ensure the reliability of the nut locking.
Three advantages of locknuts:
First, excellent anti-vibration performance: When the thread is tightened, the crest thread of the bolt is tightly entered into the 30° wedge-shaped slope of the nut to be clamped, and the normal force exerted on the wedge-shaped slope is consistent with the bolt’s The axis is at an angle of 60° instead of 30°. Therefore, the normal force generated when the locknut is tightened is much greater than that of an ordinary standard nut, which has great anti-loosening and vibration resistance.
Second, strong abrasion resistance and shear resistance: the 30° inclined surface of the nut thread bottom can make the nut locking force evenly distributed on all the threads of each tooth. Because the compression force on the thread surface of each tooth is evenly distributed, so Nuts can better solve the problems of thread wear and shear deformation.
Third, good reusability: extensive use shows that after repeated tightening and disassembly of the locknut, its locking force is still not reduced, and the original locking effect can be maintained.
