Sharing the function of disc springs

　   Like most other basic mechanisms, metal springs have existed for a long time since the Bronze Age. Even metal was used as structural components in military catapults. During the Renaissance, clocks made springs a necessity. The fourteenth century witnessed the revolutionary development of astronomical navigation clocks. The world's exploration and conquest by European colonial powers continuously provided impetus for watchmakers' "science and art." Another field of firearms promotes.Disc springDevelopment.

       Disc springs have fatigue resistance, oxidation resistance, radiation resistance, and corrosion resistance, along with good processing and welding performance. They can manufacture parts of various complex shapes. In aerospace, nuclear energy, petroleum industry, and extrusion molds, they have been widely used within the aforementioned temperature range. High-temperature disc springs are mainly used for flange bolt fastening in reactors, heat exchangers, high-temperature valves, and pumps, especially for bolt connections with a temperature difference exceeding 100.

　　High-temperature disc springs have a compensation function, compensating for the repeated changes in preload caused by thermal expansion and contraction, maintaining stable preload, and preventing bolt fatigue and gasket failure. Changes in preload caused by medium pressure variations can be compensated by it, preventing bolt and gasket failure.

    Disc springs bear large loads in a very small space. Compared with other types of springs, disc springs have greater deformation energy per unit volume. They have good buffering and shock absorption capabilities, especially when using layered combinations, where the effect of absorbing impacts and dissipating energy is more pronounced due to surface friction resistance.

　　Disc springs have variable stiffness characteristics. By changing the ratio of the conical height to the disk thickness, different spring characteristic curves can be obtained, which can be linear, increasing, decreasing, or combinations of them. In addition, variable stiffness characteristics can be achieved through different combinations of disks of varying thickness or laminated disks with different numbers of disks.

　　Disc springs can achieve different load capacities and characteristic curves by changing the number of disks or the combination of disks. Therefore, each size of disk can be used in a wide range of applications, making the preparation and management of spare parts easier.

　　In combination springs that bear large loads, each disk is smaller in size, which is beneficial for manufacturing and heat treatment. When certain disks are damaged, they can be replaced individually, making maintenance and repair convenient. Properly designed and manufactured disc springs have a long service life. Because they are annular, the force is transmitted concentrically.

      Using this washer-type metalDisc spring, the stroke is relatively short when fixing screws, but the fastening pressure it can withstand can be very large. In other words, it bears heavy loads. Therefore, this disc spring fastener is suitable for use in situations where screws need to be tightened particularly tightly.
