Description

Technical Field

[0001] The utility model relates to the technical field of disc springs, in particular to a disc spring with a retaining frame. Background Art

[0002] Disc springs are elastic elements used in spring devices, usually made of metal, with a thin and wide circular or oval shape. Disc springs are usually designed as flat disc-shaped structures, which can produce elastic deformation when subjected to external forces and can return to their original shape. Disc springs are commonly used in various machinery and industrial equipment to provide spring force to support or adjust force-bearing parts, and to absorb shock, vibration and deformation. By connecting two disc springs together, their spring forces can be superimposed on each other, thereby achieving a greater synthetic spring force, improving the overall load-bearing capacity and elastic support effect.

[0003] After searching, the patent number is CN104271980A, and the specific name is a disc spring, which has: a plurality of fixing parts, which are arranged at a plurality of positions separated in the circumferential direction and fixed with a party component; a plurality of abutting parts, which are arranged between the plurality of fixing parts in the circumferential direction and abutted by the other party component; a plurality of flat parts, which are arranged between the fixing parts and the abutting parts in the circumferential direction and extend in a direction orthogonal to the approach and separation direction of the one party component and the other party component, and the flat parts are bent by pressing the abutting parts relatively to the side of the one party component, thereby exerting elastic force;

[0004] When traditional disc springs are installed in pairs, elastic deformation will occur during use. If the two matched disc springs are misaligned, the misalignment of the disc springs may increase the friction between the disc springs during use, aggravate the wear of the disc springs, and reduce the service life of the disc springs. The misalignment of the disc springs may cause uneven distribution of spring force, with one disc spring bearing too much load while the other bears a smaller load, causing an imbalance in spring force and reducing the stability and reliability of the system. The misalignment of the disc springs may cause the original design performance of the disc spring to be destroyed, reducing the elastic characteristics of the spring, affecting the spring support effect and working performance, and reducing the service life of the disc spring. Utility Model Content

The arrangement of the longitudinal rollers 7 can provide additional support for the upper disc spring 1 and the lower disc spring 2 when they are working, effectively reducing the collision and wear between the upper disc spring 1 and the lower disc spring 2, extending the service life of the equipment, reducing noise and vibration, and through the positioning structure of the left retainer 3 and the right retainer 4, they can be quickly assembled with the upper disc spring 1 and the lower disc spring 2 for use;

[0024] Elastic pads 8 are fitted on the top and bottom ends of the groove 5. The elastic pads 8 are silicone rings. A metal ring 9 is fixedly connected to the surface of the elastic pad 8.
