A disc spring is a disc spring is a cone-shaped circular disc that bears axial loads. Usually the thickness is unchanged, the load is evenly distributed on the inner edge of the upper surface and the outer edge of the lower surface, can withstand static load, impact load and dynamic alternating load.

 

Can be used individually, but also can be used in series or parallel, in the upper inner edge and the lower outer edge of the static or dynamic load along the axial action, after being compressed, deformation, until being flattened, in the form of energy storage as a live load.
