Description

Technical Field

[0001] The utility model relates to the technical field of disc springs, and specifically relates to a corrosion-resistant disc spring. Background Technique

[0002] The disc spring, also known as Belleville spring washer, is in a conical disc shape. It can be used alone or in series or parallel combination. It bears static or dynamic loads acting axially at the upper inner edge and lower outer edge, and deforms after being compressed until it is flattened to store energy in the form of live load.

[0003] In the existing disc springs, there is a lack of positioning measures between two adjacent disc plates, which makes it easy for relative rotation to occur between two adjacent disc plates. This will affect the overall stability of the disc spring and also increase the friction between the two disc plates. For this reason, a corrosion-resistant disc spring is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a corrosion-resistant disc spring to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a corrosion-resistant disc spring, including a disc spring assembly, a plurality of the disc spring assemblies are distributed in sequence from top to bottom. The disc spring assembly is composed of two disc plates, the two disc plates are symmetrically distributed with respect to each other. The disc plate is in a horn-shaped structure. Two first positioning grooves and two first positioning blocks are arranged at the bottom of the outer ring side wall of the disc plate, and two second positioning grooves and two second positioning blocks are arranged at the top of the inner ring side wall of the disc plate.

[0006] As a further preference of this technical solution, the two first positioning grooves and the two first positioning blocks are arranged in an annular array, and the first positioning grooves and the first positioning blocks are cross-distributed.

[0007] As a further preference of this technical solution, the two second positioning grooves and the two second positioning blocks are arranged in an annular array, and the second positioning grooves and the second positioning blocks are cross-distributed.

[0008] As a further preference of this technical solution, the axis lines of a plurality of the disc spring assemblies are the same, and the deflection degree of one disc spring assembly is set relative to another disc spring assembly.

[0009] As a further preference of this technical solution, the deflection degree is set between the two disc plates of the same disc spring assembly.

[0010] As a further preference of this technical solution, the central hole of the disc plate is in a horn-shaped structure.

[0011] As a further preference of the present technical solution, a corrosion-resistant paint layer is applied to the outer surface of the disc-shaped plate.

[0012] The utility model provides a corrosion-resistant disc spring, which has the following beneficial effects:

[0013] By providing the first positioning groove and the first positioning block in the utility model, relative rotation between two disc-shaped plates on the same disc spring assembly can be prevented. By providing the second positioning groove and the second positioning block, relative rotation between adjacent disc spring assemblies can be ensured. As a result, during the use of the disc spring, the disc-shaped plate will not rotate, ensuring the stability of the disc spring during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0022] The utility model provides a technical solution: As Figures 1 to 6As shown in the figure, in this embodiment, a corrosion-resistant disc spring includes a disc spring assembly 6. A plurality of disc spring assemblies 6 are distributed in sequence from top to bottom. The disc spring assembly 6 is composed of two disc plates 1. The two disc plates 1 are symmetrically distributed. The disc plate 1 is in a horn-shaped structure. At the bottom of the outer ring side wall of the disc plate 1, two first positioning grooves 2 and two first positioning blocks 3 are provided. The two first positioning grooves 2 and the two first positioning blocks 3 are arranged in a circular array, and the first positioning grooves 2 and the first positioning blocks 3 are cross-distributed. At the top of the inner ring side wall of the disc plate 1, two second positioning grooves 4 and two second positioning blocks 5 are provided. The two second positioning grooves 4 and the two second positioning blocks 5 are arranged in a circular array, and the second positioning grooves 4 and the second positioning blocks 5 are cross-distributed.

[0023] Among them, the axis lines of the plurality of disc spring assemblies 6 are the same, and one disc spring assembly 6 is arranged with a 90-degree deflection relative to another disc spring assembly 6.

[0024] With such a setting, the second positioning block 5 on one disc spring assembly 6 can just be embedded into the second positioning groove 4 of another disc spring assembly 6, so as to ensure that there is no relative rotation between two adjacent disc spring assemblies 6.

[0025] Among them, the two disc plates 1 of the same disc spring assembly 6 are arranged with a 90-degree deflection.

[0026] With such a setting, the first positioning block 3 on one disc plate 1 can just be embedded into the first positioning groove 2 of another disc plate 1, so as to ensure that there is no relative rotation between the two disc plates 1 of the same disc spring assembly 6.

[0027] Among them, the central hole of the disc plate 1 is in a horn-shaped structure.

[0028] With such a setting, when the disc plate 1 deforms, there is enough deformation space between the b end of the inner wall of its central hole and the matching mounting shaft, ensuring that the inner wall of the central hole of the disc plate 1 will not be squeezed and damaged.

[0029] Among them, the outer surface of the disc plate 1 is coated with a corrosion-resistant paint layer to ensure the corrosion resistance of the disc spring.

[0030] The present utility model provides a corrosion-resistant disc spring, and the specific working principle is as follows:

[0031] By providing the first positioning grooves 2 and the first positioning blocks 3, it is possible to ensure that there is no relative rotation between the two disc plates 1 of the same disc spring assembly 6. By providing the second positioning grooves 4 and the second positioning blocks 5, it is possible to ensure that there is no relative rotation between two adjacent disc spring assemblies 6. Thus, when the disc spring is in use, the disc plate 1 will not rotate, ensuring the stability of the disc spring during use.

[0032] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
