Background

The locking nut is widely applied to the industries of machinery and the like, and the working principle of the locking nut is that the self-locking is carried out by adopting the friction force between the nut and a bolt. But the reliability of such self-locking is reduced in dynamic loads. In some important occasions, some anti-loosening measures are taken to ensure the reliability of nut locking, and the quality of the anti-loosening effect of the locking nut mainly depends on the interaction force between the nut and the meshing threads of the bolt. There are many ways to improve the interaction force between the engaged threads, such as structural improvement of the threads of the nut, nylon roughening of the nylon nut, surface treatment of the threads, etc., and the maximum torque of the lock nut is affected by many factors, such as strain hardening of the material, low cycle fatigue, coefficient of friction, manufacturing and assembly, and closing-in values.
