DIN 985 Carbon steel Zinc Hex Nylon Insert Lock Nuts For Locking Connector

DIN 985 Carbon steel Zinc Hex Nylon Insert Lock Nuts For Locking Connector

1. Product Description

General nut in the use of the process due to vibration and other reasons will be loose, in order to prevent this phenomenon, so the invention of self-locking nut. Self-Locking nut Its function is mainly to prevent loose, anti-vibration. For special occasions. Its working principle is usually by friction self-locking. The type of self-locking nut, which is classified by function, has a nylon ring, a neck, and a metal loosening device. They all belong to the effective torque type of anti-pine nut self-locking nut is generally rely on friction, the principle is through the embossing teeth into the sheet metal preset hole, the general square hole aperture slightly smaller than the rivet nut. The use of nuts and locking mechanism connected, when tightening the nut, locking mechanism lock ruler body, ruler frame can not be free to move, to achieve the purpose of locking; When the nut is loosened, the locking mechanism is removed and the ruler is moved along the ruler.

High-strength self-locking nut is a classification of self-locking nut with high strength and strong reliability. Mainly the introduction of European technology as a prerequisite for road-building machinery, mining machinery, vibration machinery and equipment, domestic production of such products are very few manufacturers.

Nylon locking nut is a new type of high vibration elastic solid parts, can be applied to the temperature - 50 ~ 100 ℃ of various mechanical and electrical products.
Aerospace, aircraft, tanks, mining machinery, automobile transport machinery, agricultural machinery, textile machinery and electrical products and all kinds of machinery, the demand for nylon locking nut, it is because it ant-vibration locking performance compared with other kinds of locking device, and the vibration lifespan is several times or even more higher.

2. Specification

root mother, pine nuts, satisfied that the child.
2. Application: locking connector through the wire, or other tube.
Nut works by using friction between the nut and bolt self-locking. However, in such a dynamic load lock reliability is reduced. In some important occasions and we'll take some anti-loosening measures to ensure the reliability of the locking nut. Locknut is one of them against rotation.
Lock nut anti-loosening effect depends on the merits of a nut and bolt engaging interaction between threads. Currently engaging way to improve the interaction between the threads there are many, such as structural improvements Spiralock thread nut, nylon nut nylon increasing roughness, surface treatment, thread and the like.

3. Application

High-strength self-locking nut for marine and bridge, it can convert friction into the expansion force between bolt and groove nut to achieve excellent self-locking effect. There are two slots in the upper part of the ESL nut, when the nut is tightened on the bolt, the thread of the bolt will be screwed into the narrow groove of the Nut cross section, and the thread is gradually locked by the nut side wall to achieve the self-locking function. The exquisite production process can keep the torque type of the locking element consistent, products are generally used in railway casting, rail transit, transmission systems, mining equipment, highways, military, oil production machinery, automotive industry, public facilities, subways, engines, construction machinery, aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry , metallurgical equipment, trains, compressors, medical machinery, signal systems, wind power generation.

4. Advantages

Advantage one, strong abrasion resistance and shearing ability: nut thread tooth bottom 30 degree bevel can make the nut locking force evenly distributed in all the teeth, because of each tooth thread surface pressure distribution evenly, so the nut can better solve the problem of thread wear and shear deformation. Advantage two, repeated use of good performance: a large number of use shows that the nut after repeated fastening and dismantling, the locking force is still not reduced, can maintain the original locking effect. Advantage three, Superior anti-vibration performance: When screwed, the thread of the top thread of the bolt tightly enters the NUT's 30° wedge-shaped bevel and is clamped, and the normal force exerted on the wedge-shaped incline is the angle of 60° between the bolts and the axis of the bolt. Anti-loose nuts are produced when the normal force is much larger than the common standard nut, has a great anti-loosing ability.
