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.

Abstract: The invention relates to a torsionally elastic shaft coupling comprising an input flange (1) and an output flange (2) which are each used for connecting the shaft coupling to adjacent machine elements, two serially connected, elastic elastomer members (7, 13), and an intermediate member (8) that is connected to the input flange (1) via the first elastomer member (7) and to the output flange (2) via the second elastomer member (13) in such a way that torque can be transmitted from the input flange (1) to the intermediate member (8) via the first, softer elastomer member (7) and from the intermediate member (8) to the output flange (2) via the second, harder elastomer member (13). A stop (9) which limits the torsional angle between the input flange (1) and the intermediate member (8) is located between the intermediate member (8) and the input flange (1). The aim of the invention is to further develop such an elastic shaft coupling such that the same is designed in a particularly compact fashion.

Abstract: The invention relates to a rotationally symmetrical coupling comprising an annular hub made of a rigid material, which is surrounded by an outer ring made of a rubber-elastic material. The coupling also comprises an outer contouring, which is located on the outer diameter and which is provided for positively transmitting torques, whereby the outer ring is reinforced by an embedded, annular, rigid solid body. The aim of the invention is to achieve a quieter operation of a coupling of the aforementioned type and to better protect this coupling from becoming damaged. To these ends, the invention provides that the rubber-elastic material is silicone and that the annular, rigid solid body, on the outside, has a shape, which is similar to that of the outer contouring of the outer ring and which maintains, over the circumference, a nearly constant distance from the outer contouring of the outer ring. The rigid solid body is preferably comprised of a curved, metallic strip material having a constant thickness.
