Description

Technical Field

[0001] The utility model relates to the technical field of disc spring washers, and more particularly to a disc spring testing device. Background Art

[0002] Disc spring washers, also known as Belleville spring washers, were first invented by French engineer J. Belleville over 100 years ago. In the early 1930s, engineer (GM) Almenand Laszio developed the theory, production, and quality standards DIN 2092 and DIN 2093. These standards, the first industrial standards for disc springs, were accepted worldwide and spread throughout Europe. They are now widely used by many multinational companies. Disc springs are tapered, annular discs that bear axial loads. Typically, the discs have a constant thickness, and the load is evenly distributed between the inner edge of the upper surface and the outer edge of the lower surface. Disc springs are typically made of spring steel and can be subjected to static, non-static, or dynamic loads, meeting stringent fatigue life and load loss requirements.

[0003] Disc spring gaskets need to be inspected and corrected during design and manufacturing to obtain disc spring gaskets that can withstand the designed preset pressure at a set height. However, existing disc spring gaskets cannot be accurately inspected during manufacturing, and it is difficult to detect disc spring gaskets that do not meet the design requirements, which affects the production yield of the disc spring gaskets.

[0004] Therefore, how to provide a disc spring testing device that can test disc springs is a problem that technical personnel in this field urgently need to solve. Utility Model Content
