What are the advantages of disc springs compared with springs?

Disc springs bear extremely large loads in a small space. Compared with other types of springs, disc springs have a larger deformation energy per unit volume. It has good buffering and shock-absorbing capabilities, especially when using a stacked combination. Due to the surface friction resistance, the effect of absorbing impact and dissipating energy is more significant.

Disc springs have variable stiffness characteristics. By changing the ratio of the inner truncated cone height of the disc to the thickness of the disc, different spring characteristic curves can be obtained, which can be linear, increasing, decreasing or a combination thereof. In addition, variable stiffness characteristics can be obtained through different combinations of discs with different thicknesses or stacked discs with different numbers.

Disc springs can obtain different load-carrying capacities and characteristic curves by changing the number of discs or the combination of discs. Therefore, each size of disc can be adapted to a wide range of uses, which makes the preparation and management of spare parts easier.

In combination springs that bear large loads, the size of each disc is small, which is beneficial to manufacturing and heat treatment. When some discs are damaged, they only need to be replaced individually, thus facilitating maintenance and repair.

Properly designed and manufactured butterfly springs have a long service life.

Because the disc spring is annular, the force is transmitted concentrically.
