Thin disc springs, made from metal strip, sheet, or forged blanks, exhibit a non-linear relationship between load and deformation. They are generally classified into ordinary disc springs, disc springs with radial grooves, and trapezoidal cross-section disc springs. Since the deformation and load capacity of a single disc spring often cannot meet requirements, they are typically used in combination.
They offer advantages such as small deformation, high load-bearing capacity, space saving, and the ability to achieve ideal loading characteristics through different combinations.
