| 摘要 |
The invention relates to an elastic shaft coupling (1) having a drive-side (2) and having an output-side mechanical interface (15), both interfaces (2, 15) being intended in each case for connecting the shaft coupling (1) to an adjacent machine element, wherein the shaft coupling (1) has at least two elastic rubber elements (4, 9) which are connected behind one another between the drive-side (2) and the output-side interfaces (15) and the axial material thickness (S1, S2) of which increases in each case at a growing radial spacing (R1, R2) from the centre axis (10) of the shaft coupling (1). The present invention is based on the object of reducing the amount of rubber of the shaft coupling with retention of its elastic properties. This is effected in that the respective rubber elements (4, 8) are of non-uniform configuration with regard to their torsional rigidity (C1, C2) and to be precise are so non-uniform that the torsional rigidity (C2) of one of the two rubber elements (8) is always at least one and a half times as great as the torsional rigidity (C1) of the other rubber element (4). ® KIPO & WIPO 2009
