Description

Technical Field

[0001] This utility model relates to the field of disc springs, and more particularly to a disc spring with enhanced anti-torsion properties. Background Technology

[0002] A disc spring is a type of spring that is tapered in the axial direction and bears the load. It can withstand large loads with small axial deformation and is suitable for applications where axial space is limited.

[0003] When a disc spring is compressed, it deforms, storing energy as a live load, which is automatically converted into the additional compressive load required for sealing. Ordinary disc springs use only a simple conical disc structure; when subjected to significant pressure for extended periods, this can lead to irreversible torsional deformation and damage. In the prior art, utility model patent CN220748891U discloses an anti-torsion balance disc spring. When the disc spring body is compressed to contact a return elastic ring, the return elastic ring provides an axial reaction force to help the disc spring body recover, preventing irreversible torsional deformation. However, the return elastic ring is difficult to manufacture, and the overall structure is complex and costly, requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide a torsion-resistant and reinforced disc spring, which improves the recovery performance of the disc spring body and prevents irreversible torsional deformation of the disc spring body.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A torsion-resistant and reinforced disc spring includes: a disc spring body, a pressure ring, and a ring plate. The ring plate has a through hole in the middle. The disc spring body is disposed on the top surface and / or bottom surface of the ring plate. The disc spring body is concentric with the through hole. The edge of the ring plate is provided with an arc-shaped flange located at the edge of the disc spring body. The pressure ring is disposed on the outer convex surface of the arc-shaped flange and is located above the edge of the disc spring body.

[0007] The arc-shaped flange cross section has a C-shaped structure with the opening pointing towards the ring piece.

[0008] The outer edge of the arc-shaped flange is welded to the ring piece or is an integrated structure.

[0009] The inner edge of the arc-shaped flange abuts against the edge of the disc spring body.

[0010] The pressure ring is welded and fixed to the arc-shaped flange.

[0011] The pressure ring has a circular cross-section.

[0012] The disc spring body has rounded corners at its edges.

[0013] The beneficial effects of this utility model are as follows: A torsion-resistant and reinforced disc spring is specially designed with an arc-shaped flange to provide elastic support for the edge of the disc spring body. When the disc spring body is compressed, the arc-shaped flange also deforms elastically, increasing the overall energy storage, helping the disc spring body to recover, preventing irreversible torsional deformation of the disc spring body, and using a pressure ring to compress the edge of the disc spring body to prevent the disc spring body from separating from the ring plate, ensuring structural stability. The pressure ring can also perform a slight elastic expansion to store energy when the disc spring body is compressed, thereby further improving the recovery performance of the disc spring body. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model;

[0015] Figure 2 yes Figure 1 Top view. Detailed Implementation

[0016] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 The torsion-resistant reinforced disc spring shown includes: a disc spring body 2, a pressure ring 3, and a ring plate 1. The disc spring body 2 is disposed on the top surface and / or bottom surface of the ring plate 1. In this embodiment, the edge of the disc spring body 2 is provided with a rounded corner 21 to reduce the friction between the edge of the disc spring body 2 and the ring plate 1, reduce wear, extend service life, and facilitate the recovery of the disc spring body 2 after pressure is released.

[0018] A through hole 12 is provided in the middle of the ring plate 1, and the disc spring body 2 is concentric with the through hole 12, which is beneficial for installation on shaft parts. An arc-shaped flange 11 is provided around the edge of the ring plate 1, located outside the edge of the disc spring body 2. The outer edge of the arc-shaped flange 11 is welded to the ring plate 1 or is integrated with it, which makes the structure stable and easy to process.

[0019] In this embodiment, the cross-section of the arc-shaped flange 11 is a C-shaped structure with the opening pointing towards the ring plate, so that the inner edge of the arc-shaped flange 11 can elastically deform and store energy when subjected to force.

[0020] like Figure 1As shown, the inner edge of the arc-shaped flange 11 abuts against the edge of the disc spring body 2. When the disc spring body 2 is compressed, the edge expands outward, and the arc-shaped flange 11 will also undergo elastic deformation under force, increasing the overall energy storage, helping the disc spring body 2 to recover after the pressure is released, and preventing the disc spring body 2 from undergoing irreversible torsional deformation.

[0021] The pressure ring 3 is positioned on the outer convex surface of the arc-shaped flange 11, and the pressure ring 3 is located above the edge of the disc spring body 2. For example... Figure 2 As shown, the pressure ring 3 is used to press and secure the edge of the disc spring body 2, preventing the disc spring body 2 from separating from the ring plate 1 and ensuring structural stability. The pressure ring 3 can limit the upward curling of the edge of the disc spring body 2, enhancing its anti-torsional performance.

[0022] In this embodiment, the pressure ring 3 is welded and fixed to the arc-shaped flange 11, resulting in a robust structure and further enhancing the synchronous deformation capability of the pressure ring 3 and the arc-shaped flange 11. Furthermore, the pressure ring 3 has a circular cross-section, allowing it to undergo slight elastic expansion and energy storage when the disc spring body 2 is compressed, thereby further improving the recovery performance of the disc spring body 2.

[0023] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
