Deflection in Belleville Springs

Belleville washers, and K Springs do much more than act as springs. All belleville springs have a specific amount of load and deflection. They are used very frequently in situations where high spring loads are required. Because of their ability to be stacked, it in turn stacks the amount of deflection. Unfortunately though, the number of springs or washers stacked is not proportional to the amount of deflection since there is a bottoming out effect when the springs are entirely flattened.

Many adjustments can be made to the spring characteristic and the deflection by altering certain properties of belleville disc springs such as adding slots, stacking, or changing the dimensions.

Stacking Belleville Disc Springs

Stacking is another benefit of these springs. The typical ways of stacking belleville disc springs are:

Single - only one spring
Parallel - all springs stacked in the same direction
Parallel/Series - a combination of single and parallel
Series - where all springs are stacked opposing each other

When these conical disc springs are in a parallel stack, an immense gain in the amount of load it can bear will occur. Using them in a series will increase spring deflection.

By switching the stacks into combinations of series and parallel, you are able to infinitely tweak the load and deflection characteristics. They have the ability to achieve either linear or non-linear regressive load deflection while maintaining high tension. Please read our deflection graph, to find out the loads and deflections you're looking for.

The Shape of Conical Disc Springs

Used in many applications, a large reason of why these washers have a spring characteristic is due to their shape. These conical disc springs can either come with convex, concave, linear, or negative attributes. Since they are used in many applications where high spring loads are required, their conical shape allows them to provide excellent permanent spring performance. Belleville springs also exhibit an extremely efficient use of space, they are self dampening, and have an extremely long service life.
