| 主权项 | 1. A coupling element (2; 52) for mechanically coupling adjacent blades of a rotor blade ring, which can be positioned between shrouds (14, 16), wherein the coupling element (2; 52) has force-transmission surfaces (28, 30) for defining damping gaps (12a, 12b) between shrouds (14, 16), wherein the coupling element is separately formed from the shrouds, and wherein the coupling element has a first end and a second end, and the coupling element is dimensioned and configured to be positioned such that the first end is adjacent a first axial edge of a respective shroud and the second end is adjacent a second axial edge of the respective shroud; wherein, in an incorporated state, the coupling element continues the annular spatial geometry of a flow channel. | ||
