Schnorr Disc Springs

Disc Spring Engineering
Maximum load - minimum space - maximum flexibility

stacks in series

A stack of ā€˜iā€™ springs in single series (figure 21 - b) results in the following without considering friction: 

Spring Load 

Formula 17

 

Spring Deflection 

Formula 18

 

Unloaded Stack Length 

Formula 19

 
 
Only the deflection is multiplied by the number of springs in series, not the load.
