Abstract:
Disclosed is a coupling system comprising joints configured to friction lock under compressive pressure via tapered teeth for joining rotating components, which may be rotating components of a gas turbine, or other engine. The coupling system provides the alignment orientation for the joined components, and eliminates the need for extraneous fasteners, bolts, interference fits and/or keying arrangements. The coupling system further enables material optimization by allowing for use of different materials throughout different engine sections, depending on the operating parameters.

Claim (Index 4):
A coupling method for joining rotating components comprising:\n stacking the rotating components to form a rotating stack aligned along a central axis, wherein the rotating components are supported on joints wherein the rotating stack is formed by adjacently aligning the joints, and wherein each of the joints comprises tapered teeth which are configured to intermesh with the tapered teeth of an adjacent joint, wherein each tooth of the tapered teeth comprises tapered side walls; and applying a compressive force to the rotating stack to cause the joints to friction interlock with one another due to the frictional forces between the tapered side walls, wherein both tapered side walls of each tooth of the tapered teeth friction interlock with adjacent teeth of the adjacent joint.
