Anti-loosening nut is a common type of tightening anti-loosening nut. In some important occasions, in the operation of mechanical equipment, the nut will loosen due to long use time. At this time, we will take some anti-loosing measures to ensure that the nut is locked. The reliability of the locknut comes in handy. Many of the current locknuts are made of nylon, that is, a layer of nylon is embedded on the nut to make the locknut.
Introduction to the advantages of locknuts:
1. Anti-vibration performance: The normal force generated when the anti-loosening nut is tightened is much greater than that of the ordinary standard nut, which has a great anti-loosening and anti-vibration ability.
2. There is directionality. The standard nut is non-directional, it can be screwed in from either end of the nut (bolt). The thread is directional, and the locking force can only be generated after the bolt is screwed in one direction. Therefore, it is recommended to use flange locknuts or flange locknuts with directional characteristics in the shape of nuts to prevent incorrect installation.
3. 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. Since the compression force on each thread surface is evenly distributed, the nut It can better solve the problems of thread wear and shear deformation.
4. The anti-loosening nut has good repeated use performance: a large amount of use shows that the number of repeated use mainly depends on the use environment. After repeated tightening and disassembly of the anti-loosening nut, its locking force is still not reduced, and the original locking effect can be maintained.
