A buffer type wave elastic washer for precision mechanical parts installation

Abstract

The invention relates to a buffer type corrugated elastic gasket for precision mechanical parts mounting. The buffer type corrugated elastic gasket comprises a buffer device and a main gasket device,wherein the main gasket device is installed at the upper end of the buffer device. According to the buffer type corrugated elastic gasket, the problems that when an existing corrugated gasket matcheswith a nut to screw tightly, the screwing nut can easily scratch the surface of the existing corrugated gasket, the existing corrugated gasket is only provided with one thin rubber gasket, the elasticforce is insufficient, the nut cannot be abutted to prevent from falling, the tightened nut is prone to rusting due to the fact that the nut is in contact with the existing corrugated gasket for a long time, the nut is not easy to unscrew, and the service life of the existing corrugated gasket is reduced can be solved; the functions that the nut can be further abutted, an upper gasket is not abraded, and the upper gasket and the nut can be separated before unscrewing can be achieved; and the upper gasket is rotated along with the nut until is tightened, the surface of the upper gasket cannotbe scratched, a bottom ring, an annular plate and the upper gasket are matched to carry out multiple-layer abutting of the nut, so that the nut is not easy to fall off, and the nut and the upper gasket which are stuck together by the rust are manually adjusted and separated.

Description

technical field [0001] The invention relates to the technical field of wave washers, in particular to a buffer type wave elastic washers for installing precision mechanical parts. Background technique [0002] Wave washer, also known as wave washer, is a round sheet with regular waves, which is widely used in the installation of precision mechanical parts. It is generally used to prevent loosening and buffer impact, and it needs to have good elasticity and impact resistance. When the existing wave washer is tightened with a nut, the nut during the screwing is easy to scratch the surface of the existing wave washer. The existing wave washer only has One layer of thin rubber pad has insufficient elasticity and cannot be pressed against the nut so that it does not fall off. The tightened nut is easy to rust due to long-term contact with the existing wave washer and is difficult to unscrew, which reduces the service life of the existing wave washer.

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a cushioning type wave elastic washer for precision mechanical parts installation, which can solve the problem that when the existing wave washer is tightened with a nut, the nut being twisted is easy to scratch the surface of the existing wave washer. Some wave washers only have a thin layer of rubber pad, which is not elastic enough to hold the nut tightly so that it does not fall off. The tightened nut is prone to rust due to long-term contact with the existing wave washer and is not easy to unscrew, which reduces the existing wave shape. The service life of the washer and other problems can realize the function of further tightening the nut, the upper washer is not worn, and the function of separating the upper washer and the nut before unscrewing. The upper washer follows the rotation of the nut until it is tightened, and the surface of the upper washer will not be scratched. , the bottom ring, the ring plate and the upper washer cooperate with each other to tighten the nut in multiple layers to make it difficult to fall off, and manually adjust and separate the rusty nut and the upper washer, which reduces the difficulty of unscrewing the nut and prolongs the service life. life
