Abstract
A resilient coupling with relative rotation limitation. The coupling comprises an annular hub that fits into a concentric annular flywheel while separated from it at least to some extent by a radial interval such that the flywheel can rotate relative to the hub. A spring element of elastomeric material is accommodated between the hub and the flywheel. The hub has a first flange that extends radially outward and the flywheel has a second flange that extends radially inward such that the hub and flywheel respectively reinforce each other while permitting relative rotation. The first flange on the hub has recesses that open toward the flywheel and the second flange on the flywheel has recesses that open toward the hub. The first and second flanges overlap in the region of the recesses with the edges of the recesses forming opposing contact surfaces. The opposing contact surfaces are so delimited in the circumferential direction as to provide separation in at least one direction of the rotation.
