The rotor (1) has blades arranged adjacent to each other in a circumferential direction (6), where the rotor is formed along an axial direction. The blades have an arcuate blade root (5) that is arranged in a groove (2). A damping element (7) is arranged between the blade root and the groove. The blade root is arcuated towards the axial direction. The blade root has a side wall (9) and a lower side (8) aligned towards a rotational axis. The damping element is made of a spring elastic material and arranged between the side wall and the groove.
