Advantages of self-locking nuts

a) Reliable anti-vibration and anti-loosening performance;

b)Can improve the service life of nuts and bolts and can be reused;

c)Not affected by drastic changes in temperature, a wide range of applications;

d)Free rotating type, torque is not applied until tightening, easy to install and remove;

e) unlimited size specification, can match with standard bolts;

f) no need for any auxiliary locking components, such as spring washers, stop shims, etc.; kind of anti-loosening, the vibration-proof performance of the self-locking screw holes for the required occasions;

h) self-locking nuts have a significant effect on overcoming the problem of slipping teeth of soft materials (such as aluminum alloy).

Application of self-locking nuts.

a) Suitable for temperature changes drastically, under the conditions of abnormally harsh environment, while bearing huge vibration load, no nut loosening occurs after 10 times repeated use;

b) Suitable for working conditions subjected to huge vibration, such as 0 kHz-2 kHz for overhead rail beams;

c) Suitable for applications subjected to solid shock, chattering, and bending loads;

d) applicable to fast braking systems, with good anti-loosening performance under high temperatures of 310°c for brake discs;

e) applicable to reciprocal rotation, movement, and speed frequently changing the fastening of the machine parts;

f) applicable to applications where permanent cannot be loosened and slipped off machine parts connection, such as artificial joints, artificial knees, and other connecting equipment;

g) can be used as the adjustable nut of the spring, with good adjustable and self-locking performance.

h) Suitable for applications with high power transmission and fastening requirements, such as the main drive shaft. It has entered many fields, and the scope of application is expanding, China's railroads, ports, steel, automobiles, bridges, subways, etc. have been widely used, and the textile industry has good prospects for application.

The function of self-locking nuts is mainly to prevent loosening and vibration. Used for special occasions. The working principle is generally self-locking by friction. The types of self-locking nuts by function are embedded nylon rings, with neck closures, plus metal anti-loosening devices. They all belong to the effective torque type lock nut.

Self-locking nut is a new type of high-vibration anti-loosening fastening parts, that can be applied to the temperature -50 ~ 100 ℃ in a variety of machinery, and electrical products. In aerospace, aviation, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products, and all kinds of machinery the nylon self-locking nut demand has increased sharply, because its anti-vibration anti-loosening performance is much higher than various other anti-loosening devices, and vibration life is several times or even dozens of times higher. Self-locking nut is generally by friction, its principle is through the embossed teeth pressed into the sheet metal pre-set hole, generally square pre-set hole diameter is slightly smaller than the pressure rivet nut. Using the nut and locking mechanism connected, when tightening the nut, the locking mechanism locks the ruler body, and the ruler frame can not move freely, to achieve the purpose of locking; when loosening the nut, the locking mechanism of the ruler body, the ruler frame move along the ruler body. The self-locking nut is composed of 4 parts: sealing cover, self-locking nut, pressure ring, and sealing ring.
