Abstract:
1. A torsionally elastic shaft coupling, comprising: a) a drive flange and a power take-off flange, for connecting the shaft coupling with adjacent machine elements, b) two elastic elastomer bodies switched in series, and c) an intermediate member that is connected with the drive flange by way of a first elastomer body and with the power take-off flange by way of a second elastomer body, such that the torque is transferred from the drive flange to the intermediate member by way of the first elastomer body, and from there, to the power take-off flange, by way of the second elastomer body, wherein a spring stiffness of the first elastomer body is less than a spring stiffness of the second elastomer body, wherein a torsion angle between drive flange and intermediate member is limited by a rigid stop disposed radially outside of the first elastomer body and radially outside of the second elastomer body, wherein the elastic elastomer bodies are configured essentially in ring shape and disposed concentrically, and wherein the second elastomer body surrounds the first elastomer body.
