Abstract
A compression spring comprising a plurality of composite wave rings stacked and attached to one another in crest to crest configuration. Each of the wave rings has a plurality of alternating peaks and troughs wherein one peak and one adjacent trough define a wave having a wave height measured axially from the peak to the trough and the wave heights vary such that the compression spring provides a varying spring rate as the compression spring is compressed.
Claims12
A compression spring comprising:
- a plurality of composite wave rings stacked and attached to one another in a crest to crest configuration;
- each of said wave rings having a plurality of alternating peaks and troughs wherein one peak and one adjacent trough define a wave having a wave height measured axially from said peak to said trough, each of said waves within a particular wave ring having the same wave height;
- said wave heights varying between individual ones of said wave rings such that said compression spring provides a varying spring rate as said compression spring is compressed;
- each of said wave rings further including a ridge formed therein to allow a top surface of one wave ring to inter-lock with a bottom surface of an adjacent wave ring, thereby making the wave rings self-aligning.
