How does the lock nut achieve the perfect anti-loosening effect? The lock nut is composed of two parts, each part has a staggered cam. Because the internal wedge design slope angle is greater than the bolt nut angle, this combination is tight It bites into a whole. When vibration occurs, the convex parts of the DISC-LOCK lock nut move with each other to generate lifting tension, so as to achieve a perfect anti-loosening effect.
The lock nut is a structural anti-loosening. Through the design improvement on the thread structure, a self-locking function is obtained without resorting to other external factors. This method is extensive, and the environmental requirements are relatively low, such as Spirax lock nuts. There are many types of locknuts, such as nylon nuts and flange nuts. In short, this kind of locknut is used to prevent loosening. Twist the nut onto the screw, screw, bolt, etc., so that it won’t come loose. They can be actively connected together, so that they are firm and stable to a high degree.
The anti-loosening effect of the lock nut mainly depends on the interaction force between the nut and the bolt engaging thread. There are many ways to increase the interaction force between the meshing lines, such as the structural improvement of the nut thread, the nylon roughening of the nylon nut, and the surface treatment of the thread.
The working principle of the lock nut is self-locking through the friction between the nut and the bolt. However, the reliability of this dynamic load self-locking is reduced. In some important cases, we will take some anti-loosening measures to ensure the reliability of the nut lock. The use of lock nuts is one of the measures to prevent loosening.
