Introduction: in the work will often encounter nuts in use due to vibration or other reasons become loose or even fall off, in order to avoid this situation, people invented the self-locking nut. Self-locking nut can mainly do, anti-vibration, relaxation, etc., its principle is to rely on friction to achieve the effect of self-locking solid. Self-locking nuts are also categorized in function, divided into with neck closure, with nylon ring, plus metal anti-loosening device. They are effective in preventing the nut from falling off. The following is a detailed explanation to you.
Principle of self-locking nuts
Self-locking nuts generally rely on friction, the principle of which is through the embossed teeth pressed into the sheet metal pre-positioned holes, the general square pre-positioned holes in the aperture is slightly smaller than the pressure rivet nut.
Use the nut is connected to the locking mechanism, when the nut is tightened, the locking mechanism locks the ruler body, the ruler frame can not be free to move, to achieve the purpose of locking; when the nut is loosened, the locking mechanism is disengaged from the ruler body, and the ruler frame is moved along the ruler body. Foreign brands of self-locking nuts.
High-strength self-locking nuts for ships and bridges, which can convert the friction force into the expansion force between the bolt and the slotted nut thus achieving excellent self-locking effect.
ESL nuts have two slots in the upper part, when the nut is tightened on the bolt, the threads of the bolt will be screwed into the slots on the cross section of the nut, and the threads will be gradually locked by the side wall of the nut to achieve the self-locking function. Exquisite production process can make the type of torque of the locking element to maintain the same, the product is generally used in railroad casting, rail transportation, transmission system, mining equipment, highway, military, oil extraction machinery, automotive industry, public **** facilities, subway, engine, construction machinery, aerospace, drilling equipment, bridges, generators, agricultural machinery, the shipbuilding industry, metallurgical equipment, trains, compressors, medical machinery, Signal system, wind power generation.

In the material self-locking nuts and ordinary nuts have nylon material, the reason is that because of the nylon material damping effect is stronger, so that the nut in the function of the nut has a stronger solidity. In the ordinary nut installation are in order to prevent the fall of the curtain fall off, in the installation of the home on the spring spacer. Self-locking nuts in the function of superiority far beyond the performance of ordinary nuts, today on the self-locking nuts on the explanation here thank you for watching.
