Abstract
The invention relates to an elastic shaft coupling having at least one torsion element (1) which comprises at least one elastomer body (5) serving as a transmission element. Axial metallic connecting flanges (2) are mounted in a fixed manner, preferably by vulcanization, on the input and output sides of the elastomer body. In order to increase the transmittable power density and to improve the rubber-metal connection in the edge areas of the connecting flanges (2), the invention provides that the connecting flanges (2) axially project outward with regard to the elastomer body (5) from the plane of the connecting flange while forming an arch at least on the radially extending edges (2a, 3a) of the connecting flanges between the elastomer body (5) and the connecting flanges (2), the edges being formed on the outer edges of connecting flange segments (2) and/or on the inner edges of passages (3) in the connecting flange (2). In addition, the elastomer body (5) is connected to the flanges by vulcanization along the arched area.
