diaphragmsprings

Diaphragm springs, also known as Belleville washers or disc springs, are conical ring-shaped components that store and release energy through elastic deformation. They are essentially a series of specially shaped, thin discs that can be stacked together or used individually. Their design allows them to exert a significant force over a relatively small distance. When compressed, the conical shape of the spring flattens, providing a spring force.

The primary advantage of diaphragm springs lies in their high spring force-to-volume ratio, meaning they can generate a lot of force in a compact space. They also offer a relatively linear force-deflection characteristic when used individually, but stacking them in series or parallel configurations can alter this behavior, allowing for customized spring rates and travel. They are known for their durability and ability to withstand high temperatures and harsh environments.

Diaphragm springs find widespread application in various industries. They are commonly used in clutches for automotive and industrial machinery, providing the necessary clamping force to engage and disengage the clutch. Other uses include pressure relief valves, pre-loading bearings, shock absorption systems, and as a flexible seal in certain mechanical assemblies. Their compact size and high force output make them an efficient solution for applications where space is limited and high spring loads are required.
