Defining Disc Springs
In the middle of the nineteenth century the conical shaped spring disc was invented. This spring disc was subsequently termed a “Belleville Washer” after the name of its inventor, Julian F. Belleville. In the 21st century, disc springs are used in endless devices such as spacecraft, satellites, medical devices, defence systems, automobiles and machine tools, to name a few.
Disc springs are conical shaped washers designed to be loaded in the axial direction only… “F”. Disc springs can be statically loaded, either continuously or intermittently, or cyclically deflected i.e. dynamically loaded.
Buy using disc spring singularly or stacked in combinations variable spring characteristics can be achieved to suite a given application.
