Belleville spring, also known as Belleville spring washer, was first invented by French J. Belleville more than 100 years ago. In the early 1930s, engineers (GM) Almen and Laszio developed theories and developed production, quality standards DIN 2092 and DIN 2093. These standards have been accepted around the world as the first industrial standard for disc springs, and have spread throughout Europe and are now widely used by many multinational companies. Next Xiaobian introduced the function of the disc spring and the characteristics of the disc spring.
The function of the disc spring
The shape of the disc spring is a conical disc shape. Different from the traditional spring, the function has its special function. The main features are: large load, short stroke, small space required, easy combination use, easy maintenance and replacement, and economic security. High. Suitable for precision and heavy machinery with small space and large load. The best range of compression stroke is between 10% and 75% of the maximum compression stroke.
Disc Spring Features
1. Stiffness, strong cushioning and vibration absorption capability, can withstand large loads with small deformation, suitable for occasions with small axial space requirements.
2, with variable stiffness characteristics, this spring has a very wide range of nonlinear characteristics.
3, using the same disc spring using different combinations, can make the spring characteristics vary widely. The combination of overlap and overlap may be used, and the combination of different thicknesses, different numbers of sheets, etc. may also be used.
Disc Spring Surface Treatment
1. General surface treatment of the disc spring: add lubricating oil after phosphoric acid treatment.
2. The special surface treatment of the disc spring: plating, zinc, steel, chrome, metal film, paint and other plating processes.
The advantages of the disc spring compared with the cylindrical coil spring
1. The load deformation characteristic curve is nonlinear.
2. The disc spring is in the shape of a thin plate, which is easy to form assemblies, and can be assembled and replaced by building blocks, thus bringing convenience to maintenance.
3, radial grooved disc spring has zero stiffness characteristics. This characteristic can be used in a certain deformation range where the spring force is required to remain basically stable.
4. The vibration absorption performance of the disc spring is not lower than that of the cylindrical coil spring. When the overlapping combination is adopted, the friction between the disc reeds has large damping and dissipates the impact energy.
Editor's summary: The function of the disc spring and the characteristics of the disc spring are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
