1. Description
A Belleville Washer, also known as a
Coned-Disc Spring, Conical Spring Washer, Disc Spring, Belleville Spring or
Cupped Spring Washer, is a type of spring shaped like a washer. It has a
frusto-conical shape which gives the washer a spring characteristic. The
Belleville name comes from the inventor Julian F. Belleville.
The Belleville
Washer consists primarily of a convex disc supported at the outer periphery by
one force and an opposing force on the center of the disc. Disc Springs are used
singly, or in stacks, to achieve a desired load and travel. The advantage of a
DISC Spring is that it generates high force in a very short spring length and
with minimal movement when compressed. All DISCs are preset so that they will
not significantly relax under load over time.
