Patent ID: 8033919

Claim:
Elastic shaft coupling having a mechanical interface on the drive side and a mechanical interface on the power take-off side, both interfaces for connecting the shaft coupling to an adjacent machine element, in each instance, whereby the shaft coupling has at least two elastic rubber bodies placed one behind the other between the interface on the drive side and the interface on the power take-off side, whose axial material thickness increases with an increasing radial distance from the center axis of the shaft coupling, in each instance, wherein the torsional stiffness of one of the two rubber bodies is at least one and a half times as great as the torsional stiffness of the other rubber body, and wherein the axial material thickness of one of the two rubber bodies, at a radial distance, is always at least one and a half times as great as the axial material thickness of the other rubber body, at the same radial distance.
