A Belleville washer is a type of spring shaped like a washer. It is the shape, a cone frustum , that gives the washer its characteristic spring. The "Belleville" name comes from the inventor Julien Belleville who in Dunkerque , France, in 1867 patented a spring design which already contained the principle of the disc spring.
A washer with a slight conical shape, which provides an axial force when deformed. The surface may be serrated, which will have improved locking capabilities. [4] Curved disc spring Similar to a Belleville, except the washer is curved in only one direction, therefore there are only four points of contact.
A belleville may supply the designed pre-load, but the bolt may have an additional locking mechanism (loctite, for example) that would fail without the belleville.

These single-leg landing gear struts also made use of stacks of conical Belleville washers inside them as their main form of suspension for takeoffs and landings. By 1938, the design had received a series of radical modifications to adapt the Ju 88 to function as a "heavy" dive bomber in response to a request from the RLM. [14]
Much simplified was the suspension, which was intended to be based on the concept of using conical-spring Belleville washers for the E-series AFVs as a whole. These were simply bolted on to the chassis and could be easily removed for repair or replacement. This suspension system was later used on the Swiss Panzer 61. A most interesting aspect ...
A newly developed DDS (damped diaphragm steel) clutch featured a billet steel basket with cushioning dampers, and made use of a 250 Nm Belleville spring washer for the first time instead of the customary conical springs, greatly reducing clutch operation force. Both the clutch master and slave were produced by Brembo. The frame was completely ...
