XB00018302 NUT LOCK For HITACHI ZX220W-7 4HK1

Locking nut is a kind of nut widely used in machinery and other industries. Its working principle is self-locking by friction between nut and bolt. However, the reliability of this self-locking will be reduced under dynamic load. On some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. The working principle of nut is self-locking by friction between nut and bolt. However, the reliability of this self-locking will be reduced under dynamic load. On some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Locking nut is one of the anti-loosening measures. The anti-loosening effect of lock nut mainly depends on the interaction between nut and bolt meshing thread. There are many ways to improve the interaction force between meshing threads, such as improving the structure of nut threads, roughening nylon nuts, and surface treatment of threads.

NUT LOCK is a fastener used to connect bolts and nuts. Its main function is to prevent bolts and nuts from loosening during vibration or repeated use. The specific working principle of NUT LOCK is that through its special thread design, when the nut is tightened, the thicker thread will cut and bend or break the thinner thread, thus firmly connecting the bolt and nut together. This design ensures that the connection will not loosen even in the case of vibration or repeated use, thus improving the stability and safety of the connection.

The main function of the lock nut is to prevent the bolt from loosening and ensure the stability and safety of the connection. Through different design principles and structures, the lock nut can effectively lock the bolt and avoid the connection failure caused by vibration or dynamic load. The specific action mechanism of the lock nut includes the following aspects: by generating greater friction between the nut and the bolt, the nut is prevented from loosening under vibration or dynamic load. Some locking nuts are designed as round nuts, and there are notches on their outer periphery, which are deformed when tightened by crescent wrenches, thus locking bolts. For example, the nylon insert self-locking nut is extruded into a spiral on the bolt thread through the nylon ring to form a close fit and increase the friction. Use two identical nuts to screw on the same bolt, and increase the reliability of the connection through additional tightening torque.
