The disc spring, also known as the Belleville spring washer, was invented by the Frenchman Belleville. It has a conical disc shape. It can be used singly or used in series or in parallel. It bears the edge at the upper inner edge and the lower outer edge. The axially acting static or dynamic load deforms after being compressed until it is flattened, and acts as a live load in the form of stored energy. When necessary, it is automatically converted into the additional compression load required for sealing to reduce the continuous tightening requirements for gaskets and packing.

The disc spring is a special spring that is tapered in the axial direction and bears the load. After being deformed under the load, it stores a certain potential energy. When the bolt is loosened, the disc spring releases part of the potential energy to maintain the pressure between the flange connections. Sealing requirements. The stress distribution of the disc spring decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force.
Features:
1. Large rigidity, strong shock absorption capacity, able to withstand large loads with small deformation, suitable for occasions with small axial space requirements.
2. With variable stiffness characteristics, this spring has a wide range of nonlinear characteristics.
3. Using the same disc spring with different combinations, the spring characteristics can be changed in a wide range. It can adopt the combination method of involution and superposition, and also adopt the combination method of compounding different thickness and different number of pieces.
4. When overlapped, relative to the same deformation, the greater the number of springs, the greater the load.
characteristic:
◆ Short stroke and heavy load
◆ Small space required
◆ Easy to use in combination
◆ Easy maintenance and replacement
◆ Economical and high safety
◆ Long service life
To a large extent, disc springs are replacing cylindrical coil springs. Commonly used in heavy machinery, artillery, aircraft and other weapons, as a powerful buffer and damping spring, as a compression spring for clutches and safety valves of automobiles and tractors, and as an energy storage element for mobile equipment.
Disadvantages: The load deviation is difficult to guarantee.
Disc springs can be divided into three categories according to different cross-sectional shapes: including ordinary disc springs, disc springs with radial grooves, and trapezoidal cross-section disc springs. Ordinary disc springs are divided into two types with supporting surface and non-supporting surface; disc springs with radial grooves are based on ordinary disc springs. Several uniformly distributed grooves are opened in the radial direction. The grooves can be The inner hole is opened in the direction of the outer circle, or from the outer circle to the direction of the inner hole; trapezoidal section disc springs can be divided into two types: the inner edge thickness is greater than the thickness of the external aid and the inner edge, thickness is less than the outer circle thickness.
Since the deformation and load value of a single disc spring often cannot meet the requirements of use, it can be used in groups to form a disc spring assembly (column). The typical combination method is: superimposed combination disc spring, composite combination disc spring and other combination disc springs.
