Abstract
The utility model relates to the technical field of nuts, in particular to a nut with high wear resistance. The nut with high wear resistance comprises a nut body, wherein first grooves are formed in the upper surface and the lower surface of the nut body, a plurality of third grooves are formed in the outer surface of the nut body, first wear-resistant coatings are arranged in the third grooves, threads are formed in the inner wall of the nut body, a plurality of second grooves are formed in the thread surface, teeth are arranged between two adjacent second grooves, second wear-resistant coatings are arranged on the second grooves and the surfaces of the teeth, and a third wear-resistant coating is arranged on the top end of the side surface of the threads. The second wear-resistant coating and the third wear-resistant coating are both made of wear-resistant materials, so that the function of protecting the surface of the thread is achieved, and meanwhile, a plurality of second grooves are formed in the surface of the thread, so that the surface area contacted with a bolt during nut installation is reduced, friction is reduced, and thread damage is avoided.
Description
Technical Field
The utility model relates to the technical field of nuts, in particular to a nut with high wear resistance.
Background
The nut is a part which is screwed together with a bolt or a screw rod to play a role in fastening, all the production and manufacturing machines are necessary, the center of the nut is provided with a hole, the inner side of the hole is provided with threads, the nut is often shared with the screws with the same size to fix the relevant joint part, and the nut is hexagonal in shape and square in shape. When a worker uses a wrench to install and detach the nut, the outer surface of the nut is scratched carelessly, so that the nut cannot be installed and detached; the threads of the nut can also cause thread damage when the nut is installed and removed.
Disclosure of Invention
The utility model aims to solve the defects in the prior art, and provides a nut with high wear resistance.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the nut comprises a nut body, wherein first grooves are formed in the upper surface and the lower surface of the nut body, a plurality of third grooves are formed in the outer surface of the nut body, first wear-resistant coatings are arranged in the third grooves, threads are formed in the inner wall of the nut body, a plurality of second grooves are formed in the threaded surface, protruding teeth are arranged between every two adjacent second grooves, second wear-resistant coatings are arranged on the surfaces of the second grooves and the protruding teeth, and third wear-resistant coatings are arranged on the top ends of the side surfaces of the threads.
Preferably, the first wear-resistant coating, the second wear-resistant coating and the third wear-resistant coating are all chrome-plated alloy materials.
Preferably, the top end of the third wear-resistant coating is arc-shaped.
Preferably, the upper surface and the lower surface of the nut body are both sprayed with an antioxidant coating.
The nut with strong wear resistance has the beneficial effects that: the first wear-resistant coating is made of wear-resistant materials, and plays a role in protecting the outer surface of the nut when a worker installs and removes the nut by using a wrench; the second wear-resistant coating and the third wear-resistant coating are wear-resistant materials, so that the function of protecting the threaded surface is achieved, a plurality of second grooves are formed in the threaded surface, the surface area contacted with a bolt during nut installation is reduced, friction is reduced, and thread damage is avoided.
