Abstract
The disclosed invention is a novel method for constructing an Arcuate Common Vertex Spring Damper System, that can either be used as a single spring for a torsional vibration application or be used in pairs as a Dual Arcuate Common Vertex Spring Dampers System. Both these constructions yield significant improvements over the conventional Common Vertex and Dual Common Vertex seen in prior art, such as promoting a radially tighter packaging envelop, allowing the resulting device to be tuned across a greater torsional frequency range, and improving the modal decoupling response of the resulting device.

An Arcuate Common Vertex Spring Damper System (ACV-SDS) comprising:
- a first arcuate, radially oriented, annular surface having a first radial periphery proximate to the Axial Center Line (ACL) of the ACV-SDS, and a second radial periphery distal to the ACL of the ACV-SDS;
- a second arcuate, radially oriented, annular surface offset from the first arcuate, radially oriented, annular surface, having a third radial periphery proximate to the ACL of the ACV-SDS, and a fourth radial periphery distal to the ACL of the ACV-SDS;
- a third axially oriented surface that bounds the first and the second arcuate, radially oriented, annular surfaces at their first and third radial peripheries respectively;
- and
- a fourth axially oriented surface that bounds the first and the second arcuate, radially oriented, annular surfaces at their second and fourth radial peripheries respectively;
- wherein the first and the second arcuate radially oriented, annular surfaces share a coincidental Arcuate Common Vertex (ACV), and a mutual Point of Tangency (POT) located at the ACL.
