POSSIBLE COMBINATIONS OF SINGLE SPRINGS
The shape of the disc spring as a conical disc allows single springs to be combined in different ways. As a result, the characteristics of a spring combinations can be varied in almost any way desired and adapted to the requirements. In principle the following possibilities exist (figure 21):

• Single-series spring stack (series stacking)
• Parallel springs in spring sets (parallel stacking)
• Spring stack of parallel sets in series

The determination of the characteristic for assembled disc springs stack is based on the characteristic of the single (figure 21 – a).
