Description

Technical Field

[0001] The utility model relates to the technical field of locking nuts, in particular to an embedded positioning locking nut. Background Art

[0002] Locking nut is a kind of nut widely used in machinery and other industries. Its working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Locking nut is one of the anti-loosening measures. The anti-loosening effect of locking nut mainly depends on the interaction force between the meshing threads of nut and bolt. There are many ways to improve the interaction force between meshing threads, such as structural improvement of nut thread, nylon roughening of nylon nut, surface treatment of thread, etc.

[0003] An embedded positioning locking nut with the existing publication number CN103122907A is proposed. The present invention includes a threaded inner wall forming a borehole for engaging with a threaded rod; and a metal ring, including an internal threaded wall forming a hole for engaging with the threaded rod; the metal ring is made of alloy steel for being accommodated by the borehole, and when the metal ring is accommodated by the borehole of the nut, the threaded inner wall of the nut is coaxial with the internal threaded wall of the metal ring; the metal ring is an elliptical structure, and when the threaded rod is engaged with the threaded inner wall of the metal nut and the internal threaded wall of the metal ring, the metal ring becomes a circular structure, and when the metal ring becomes a circular structure, the size of the metal ring makes the stress of the metal ring less than the yield stress of the alloy steel. A method for manufacturing a locking nut includes determining the size of the metal ring, and when the metal ring is deformed into a circular structure, the stress of the metal ring can be made less than the yield stress of the alloy steel. The metal ring can use a thermal diffusion coating.

[0004] However, although the above device can make the stress of the metal ring less than the yield stress of the alloy steel when the metal ring is deformed into a circular structure, the metal ring can use a thermal diffusion coating, but when the installation body is working, the installation body may vibrate, which may cause the nut to loosen.
