An elastic shaft coupling which as a transmission element comprises at least one torsion element with an elastically deformable elastomer body on which axial flange connections are fixedly mounted on the input and output sides. The axial width of the elastomer body increases radially from the inside towards the outside. To reduce or better distribute the local mechanical and thermal load on the elastomer body resulting from the dynamic load, the invention provides for the axial width of the elastomer body to increase radially from the inside to the outside more than proportionally, at least in sections.

Elastic shaft coupling

The invention relates to an elastic shaft coupling having at least one torsion element ( ) which comprises at least one elastomer body ( ) serving as a transmission element. Axial metallic connecting flanges ( ) 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 ( ), the invention provides that the connecting flanges ( ) axially project outward with regard to the elastomer body ( ) from the plane of the connecting flange while forming an arch at least on the radially extending edges ( ) of the connecting flanges between the elastomer body ( ) and the connecting flanges ( ), the edges being formed on the outer edges of connecting flange segments ( ) and/or on the inner edges of passages ( ) in the connecting flange ( ). In addition, the elastomer body ( ) is connected to the flanges by vulcanization along the arched area.

Elastic shaft coupling having a torsion element

A shaft coupling (,) has at least one elastic torque transmission element (,) in a single piece to which connecting elements (,) are fixed at the driving and driven sides. In order to increase the stressability due to the thermal stresses on the elastic transmission elements (,) and thus to ensure higher power densities with smaller volumes, at least one cooling element (,) made of a good heat-conducting material is non-detachably embedded in the transmission element (,). The cooling element (,) extends through a core zone of maximum heat generation and through a relatively cooler outer zone of the transmission element (,).
