What Is the Function of a Disc Spring Washer?

Nov. 24, 2023



Spring washers, also called disc springs or conical washers, use spring loads to create axial flexibility. This counteracts settlements and maintains an initial level of preload.


What Are Disc Spring Washers?


Disc spring washers are conical-shaped washers typically made from high-quality materials such as stainless steel, carbon steel, or alloys. Their design comprises a series of conical discs stacked on top of each other, creating a spring-like structure. The shape allows for flexibility and the ability to absorb and distribute immense loads efficiently.


Functionality and Working Mechanism


The washers are installed between the bolt head/nut and the mating surface. Spring washers mechanical capabilities rely on the shape of the material. When subject to load, the washer undergoes elastic deformation, and then returns to the pre-deflected shape. They can be stacked, so deflection and load capacity can vary without materially affecting the forces. The forces created by the washers can differ depending on the thickness of the material, curve and size - meaning that the operator can customize the spring loads used.


The primary function of disc spring washers lies in providing controlled tension or compression within a mechanical system. They aid in maintaining bolt preload, compensating for thermal expansion or contraction, absorbing vibrations, and preventing loosening under dynamic conditions. Their ability to handle high loads in confined spaces makes them ideal for applications requiring precise and consistent force control.
