What are the characteristics of disc springs? Analysis of six must-know characteristics of disc springs.

     In order to meet the operation of some products, people inventedDisc Spring. There are not many classifications in the market, and the disc spring is also known as Belleville spring washer. Many units use disc springs in production, and people may not pay attention to the characteristics of disc springs during use. It is precisely because of these characteristics of disc springs that production work can proceed normally when other spring components cannot complete the work tasks. So what are the characteristics of disc springs? Let's take a look together!

　　1. The axial size of the disc spring is small, but the radial size is large. It can withstand a large range of axial loads under small deformation, and the deformation energy per unit volume is large, thus having good shock absorption capability, suitable for situations with small axial space, large radial space, and heavy loads.

　　2. The variable stiffness characteristics can obtain different characteristic curves by changing the ratio of the thickness of the disc spring to the height of the inner cone when the outer diameter and inner diameter are the same. z=ho/t2, is positive stiffness (high stiffness) z=0.2～1.3; z=ho/t≈2 is positive stiffness zero stiffness z=1.3～1.5; 2?ho/t?22 is positive stiffness negative stiffness z=1.5～2.3; z?22 is positive stiffness negative stiffness z2.8. In the national standard, the disc spring adopts z?2.

　　3. By changing the number or combination form of disc springs, different load capacities and characteristics can be obtained through different combinations such as stacking, combining, etc., in addition to using them individually.

　　4. When some discs in the combined disc spring are damaged, they can be replaced individually, which is convenient for maintenance and reduces costs.

　　5. The advantage of facilitating standardization is that it is conducive to mass production, improves quality, and reduces costs. Disc springs are commonly used as buffers and damping springs in heavy machinery, aircraft, artillery, etc. They are also used in clutches of cars and tractors, compression springs in pump valves, control mechanisms in automation, and elastic washers in bolt connections. As the application of disc springs becomes more widespread, they have gradually been used in many electromechanical products, replacing the original cylindrical springs.

　　6. Properly designed, manufactured, and used disc springs have a long service life.

　  Disc springs can resist fatigue, oxidation, radiation, and corrosion, as well as have good processing and welding performance. They can be manufactured into various complex shapes. In aerospace, nuclear energy, petroleum industry, and extrusion molds, they have been widely used within the above temperature ranges, etc. High-temperature disc springs are mainly used for flange bolt fastening in reactors, heat exchangers, high-temperature valves, and high-temperature pumps, especially for bolt connections with a temperature difference exceeding 100.

　　High TemperatureDisc SpringIt has a strong 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. The changes in preload caused by medium pressure variations can be compensated by high-temperature disc springs, which can prevent bolt and gasket failure.
