Belleville Disc Spring Stack Design Calculator

Screen Shot Belleville Disc Spring Stack Design Calculator

This calculator aids in designing preferred stack arrangements for your design. Disc Springs are often stacked to enhance performance characteristics. By stacking them in parallel, load bearing characteristics are enhanced. When stacked in series, greater deflection or travel is achieved. Combination stacking, in parallel and in series, increases both load bearing and deflection.To obtain the necessary spring stiffness and deflection try varying number of parallel and series spring numbers.

The equation used to find the effective spring constant K is
