ABSTRACT:
An elastic shaft coupling has a drive-side interface and an output-side mechanical interface. Both interfaces are intended in each case for connecting the shaft coupling to an adjacent machine element. The shaft coupling has at least two elastic rubber elements which are connected behind one another between the drive-side and the output-side interfaces and the axial material thickness of which increases in each case at a growing radial spacing from the center axis of the shaft coupling. To reduce the amount of rubber of the shaft coupling with retention of its elastic properties, the respective rubber elements are of non-uniform configuration with regard to their torsional rigidity and to be precise are so non-uniform that the torsional rigidity of one of the two rubber elements is always at least one and a half times as great as the torsional rigidity of the other rubber element.
