Abstract
A method of drive decoupling, and a drive decoupling device, utilized in connecting a driving member to a driven members that is attachable to a workpiece to be rotated about a drive axis, includes a laminated plurality of flexible sheet material, attached to the driving member by at least one off axis connection and to the driven member by at least one other off axis connection circumferentially spaced from the one off axis connection, and which is torsionally rigid in a plane perpendicular to the drive axis so as to accommodate any eccentricity developed through misalignment of the driving member and driven member. The coupling device is centrally apertured so that a headstock can extend therethrough. A pair of drive decoupling devices are also provided in series by connecting the driven member of one to the driving member of another. A clamp ring securing device is also provided with two fixed positioning and holding members and one spring loaded and externally adjustable positioning and holding member; the three holding members being circumferentially spaced about the ring.
