Schnorr Disc Springs

Disc Spring Engineering
Maximum load - minimum space - maximum flexibility

stacks from spring sets

This is the combination of parallel sets in series (figure 21 - d). For ‘i’ sets in series and ‘n’ springs in parallel following results without considering friction: 
Spring load 

Formula 23


Spring Deflection 

Formula 24

Unloaded Stack Length 

Formula 25

With this arrangement the spring load is proportional to the number of disc springs in parallel, while the deflection in proportional to the number of sets. In formula 25 t must be replaced with t’ if necessary.
