Disc Springs DIN2093 Type B and Type C

Short Description:

Disc springs, also known as Belleville spring washers, was invented by the French Julian F. Belleville in the mid-19th century. It is a type of washer shaped like a spring. It has a frustoconic shape which gives the washer a spring characteristic.

Disc springs can be used singly, or in stacks, to achieve a desired load and travel. They are characterized by small size, large load, easy combination and use, as well as centralized load transmission etc. All Discs are preset so that they will not significantly relax under load over time.

► Disc Springs DIN2093 Characteristic Curves

Calculated and measured load/deflection curves

As s/h_o exceeds 0.75, the calculated curve will deviate more and more from the measured curve, since the discs will be in contact with each other or with the seat, which results in a steady reduction in the length of the moment arm.

Disc Springs DIN2093 Characteristic Curves1

Load/deflection curves for various h_o/t ratios

The load/deflection curve for a single disc is not linear, it's shape being rather a function of the ration h_o/t.

Disc Springs DIN2093 Characteristic Curves2

Combinations of discs
A. Single
B. Single discs stacked in parallel
C. Single discs stacked in series
D. Pairs of discs stacked in series
Different assembly can meet your expected load requirements.
