Abstract

A flexible coupling includes a first disc and a second disc arranged along a rotation axis. The first disc and the second disc each include a radially inner hub portion, a radially outer rim portion, and a diaphragm portion extending between the hub portion and the rim portion. The first disc rim portion is connected to the second disc rim portion and the first disc has a diametral response mode that is different than a diametral response mode of the second disc to limit deformation in the flexible coupling when communicating rotation between a drive member and a driven member connected to one another by the flexible coupling. Drive trains and methods of making flexible couplings are also described.
