What are Belleville Washers, and What do They do?Belleville washers, also known as conical washers, are disc-shaped parts acting as spacers and spring washers. They get their name from their inventor, Julien F. Belleville, who patented them in 1867. They are conical in shape, with a large outer diameter and a small inner diameter.

The large outer diameter provides a larger bearing surface, and the smaller inner diameter allows for a greater deflection or load-bearing capacity. But how do Belleville washers work? Keep reading to find out.

How do Belleville Washers Work?

The conical shape of Belleville washers makes them well-suited for use as both spacers and spring washers. The large outer diameter provides a larger bearing surface, while the smaller inner diameter allows for greater deflection or load-bearing capacity.

When used as a spacer, Belleville washers prevent two surfaces from coming into contact. They can be crucial in preventing damage to delicate surfaces or in providing a gap for heat to dissipate.

Belleville washers help distribute the load evenly and prevent fasteners from loosening when used as a spring washer.
