Abstract
A torsionally elastic shaft coupling has an input flange and an output flange which are each used for connecting the shaft coupling to adjacent machine elements. There are two serially connected, elastic elastomer members, and an intermediate member that is connected to the input flange via the first elastomer member and to the output flange via the second elastomer member in such a way that torque can be transmitted from the input flange to the intermediate member via the first, softer elastomer member and from the intermediate member to the output flange via the second, harder elastomer member. A stop which limits the torsional angle between the input flange and the intermediate member is located between the intermediate member and the input flange. The shaft coupling is designed in a particularly compact fashion in that the second, hard elastomer member surrounds the first, soft elastomer member.
