Introduction
Coned disk springs, also known as Belleville Springs, have a
long history. In 1835, one Timothy Hackworth, in England, received
acknowledgment for an application in a safety valve. A Frenchman,
Julian F.Belleville, secured a British patent in the 1860's for a
particular application. AT that time, these springs were mainly
used in the buffer parts of railway rolling stock and for recoil
mechanisms of guns, etc.
Whenever space is limited, particularly in the presence of high
forces, the use of coned disk springs will be of advantage. Linear,
regressive, and even progressive load-deflection characteristics
can be obtained by varying the basic dimensions or by stacking. A
large number of standard of-the-shelf sizes is available, so that
custom sizes may not be required.
For these reasons, coned disk springs are used today in
virtually all branches of engineering with new applications
surfacing all the time.
