A Belleville Spring is a conical shaped disc that will deflect (flatten) at a given spring rate when subjected to an axial load Fp (Figure 1). This rate is usually very high relative to a coil spring, which makes a Belleville an excellent candidate where large loads must be delivered through a short movement. Some applications where Bellevilles are commonly found are: clutch and brake mechanisms in heavy equipment, punch and die sets, bearing assemblies, switchgear, and anywhere bolt pre-load must be maintained over time.
SPRINGS 2.0 Why Does a Bolt Loosen? After a bolted joint is assembled, some of the original preload is almost always lost. This happens because the components of the …
