How does a self-locking nut work

Self-locking nut is a kind of nut that realizes self-locking by friction force, which is mainly used to prevent the nut from loosening due to vibration and other reasons during use, so as to play the role of anti-loosening and anti-vibration. The common self-locking nuts are classified according to their functions with embedded nylon rings, neck closures and metal locking devices. The working principle of the self-locking nut is fixed in the preset hole through embowel teeth to form a certain friction force. When the nut is tightened, the locking mechanism locks the rule body to achieve the purpose of locking. When the nut is loosened, the locking mechanism is removed from the ruler body, and the nut can move freely. When installing the self-locking nut, remove the surface sludge of the broken bolt first, and then install the self-locking nut on the body by drilling and surfacing. The specific steps are to first matte the center of the section with a center matte, and use an electric drill with a drill bit to expand and drill through the hole of the broken bolt, and then weld the self-locking nut on the cylinder head, and process the thread in the frame with appropriate tools, and finally fix the self-locking nut on the body. All in all, the self-locking nut is self-locking through friction, and attention should be paid to details during installation to ensure the normal use of the self-locking nut.
