Description

Technical Field

[0001] The utility model relates to the field of disc springs, in particular to a high-strength vibration-damping composite disc spring. Background Art

[0002] Disc springs are widely used in many industrial applications due to their unique structure, such as heavy machinery, aerospace, and the automotive industry. In order to improve the elasticity of traditional disc springs, the single-layer high-elastic steel sheet is changed into a composite layer structure, and the middle layer is added with elastic materials. For example, the Chinese utility model patent document prior art with application number CN201620198741.X and the name of composite disc spring with an intermediate rubber layer records that the first disc spring monomer and the second disc spring monomer are bonded together with a rubber layer. Such disc springs have the advantages of strong elasticity and good use effect. However, when maintaining the above structure, it is necessary to use a special glue removal equipment to separate the middle layer from the upper and lower layers before the parts can be replaced. The maintenance cost is high, and the production cost is also high, and there are unhealthy risks to the body caused by the use of glue. Based on this, the utility model proposes a high-strength vibration-damping composite disc spring. Utility Model Content

[0003] The purpose of the utility model is to provide a high-strength vibration-damping composite disc spring to solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a high-strength vibration-damping composite disc spring, comprising an upper ring part, a middle ring part and a lower ring part which are arranged in sequence from top to bottom, wherein mounting holes are provided at middle positions of the upper ring part, the middle ring part and the lower ring part; an upper limit groove is provided on the inner side wall of the lower ring part, and a lower limit groove is provided on the outer side wall; the inner and outer side walls of the upper ring part are respectively buckled on the upper limit groove and the lower limit groove.

[0006] Furthermore, the upper ring part and the middle ring part are in the shape of a disc-shaped structure.

[0007] Furthermore, the middle ring portion is made of elastic material.

[0008] Furthermore, the upper ring part and the lower ring part are made of high-strength alloy steel.

[0009] Furthermore, the heights of the upper limit groove and the lower limit groove are higher than the thickness of the middle ring portion.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] The utility model high-strength vibration-damping composite disc spring buckles the upper ring part together through the upper limit groove and the lower limit groove on the lower ring part, and squeezes the middle ring part between the upper ring part and the lower ring part, which not only saves installation steps and reduces production and maintenance costs, but also ensures the performance of the disc spring.

[0018] like Figure 1-4 As shown, a high-strength vibration-damping composite disc spring comprises an upper ring part 1, a middle ring part 2 and a lower ring part 3 which are sequentially installed from top to bottom, and a mounting hole 4 is provided in the middle of the upper ring part 1, the middle ring part 2 and the lower ring part 3. An upper limit groove 5 is integrally formed on the inner side wall of the lower ring part 3, and a lower limit groove 6 is integrally formed on the outer side wall, and the inner and outer side walls of the upper ring part 1 are buckled on the upper limit groove 5 and the lower limit groove 6 respectively.

[0019] The upper ring part 1 and the middle ring part 2 are in the shape of a disc-shaped structure.

[0020] The middle ring part 2 is made of elastic material, which can absorb part of the vibration during the force-bearing process, reduce the wear caused by vibration between adjacent disc springs, and extend the service life of the disc springs.

[0021] The upper ring part 1 and the lower ring part 3 are made of high-strength alloy steel (42CrMoA), which has excellent fatigue resistance and a low-cycle fatigue life of about 100 times that of 1Cr8Ni9Ti stainless steel. In addition, the alloy steel contains elements such as chromium, molybdenum and vanadium to improve the strength and wear resistance of the disc spring.

[0022] The heights of the upper limit groove 5 and the lower limit groove 6 are higher than the thickness of the middle ring part 2 .

[0023] The manufacturing and installation process of this utility model is as follows:

[0024] First, select the upper ring part 1, the middle ring part 2 and the lower ring part 3 of appropriate sizes; then, place the middle ring part 2 inside the lower ring part 3; finally, snap the upper ring part 1 together with the upper limit groove 5 and the lower limit groove 6 of the lower ring part 3 respectively.

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
