The lock nut is easy to install and can be reused. Precision machinery self-locking nuts with copper pins are widely used in machine tools, engineering and other industries. The working principle of the nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking under dynamic load will be reduced. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. The lock nut is one of the anti-loosening measures.
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 improve the interaction force between meshing threads, such as structural improvement of nut threads and surface treatment of threads.
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 tightly bitten into a whole. When vibration occurs, DISC -The raised parts of the LOCK lock nut are staggered to each other to generate lifting tension, so as to achieve a perfect anti-loosening effect.
