Principle of self-locking nut
Self-locking nut generally relies on friction, and its principle is to press it into the preset hole of sheet metal through convex teeth. In general, the diameter of the square preset hole is slightly smaller than that of the riveted nut.
The nut is connected with the locking mechanism. When the nut is tightened, the locking mechanism locks the ruler body, and the ruler frame cannot move freely, thus achieving the purpose of locking. When the nut is loosened, the locking mechanism is separated from the ruler body and the ruler frame moves along the ruler body. Self-locking nuts of foreign brands.
High-strength self-locking nuts for ships and bridges can transform the friction between bolts and groove nuts into expansion force, and achieve excellent self-locking effect.
There are two grooves in the upper part of ESL nut. When the nut is tightened on the bolt, the thread of the bolt will be screwed into the groove on the cross section of the nut, and the thread will be gradually locked by the side wall of the nut to achieve the self-locking function. Exquisite production technology can keep the torque type of locking elements consistent. Products are widely used in railway casting, rail transit, transmission system, mining equipment, expressway, military, oil extraction machinery, automobile industry, public facilities, subways, engines, construction machinery, aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry, metallurgical equipment, trains, compressors and medical treatment.

In terms of materials, both self-locking nuts and ordinary nuts are made of nylon, because nylon has a stronger shock absorption effect, which makes the nuts more stable in function. In order to prevent the curtain from falling off when ordinary nuts are installed, spring washers are installed at home. The functional superiority of self-locking nut far exceeds the performance of ordinary nut. Today's explanation of self-locking nut is here. Thank you for watching.
