Abstract
A one piece, mechanical, flexible coupling for interconnecting driving and driven shafts, which is capable of accommodating separate or combined angular, skewed or parallel shaft misalignments and axial shaft movements while permitting limited torsional or radial deflection thereof. The coupling is fashioned from a single piece of metal or other rigid material and includes a plurality of parallel, axially spaced, annular discs lying normal to the coupling's longitudinal axis and integrally interjoined with one another and with two shaft connector hubs by intervening spacers. The discs and hubs operate as flexible, zero back lash coupling portions at opposite ends of an integrally intervening midsection which operatively permits limited radial or torsional shaft deflection and is made up of a selected number of elongated flexible vane elements lying parallel to and radially displaced from the central longitudinal axis of the coupling.
