Patent ID: 8888456

Claim:
A rotor for a turbo machine having rotating blades ( 12 ), which are joined to a basic rotor body ( 14 ), in which a damping element ( 24 ) for damping blade vibrations is disposed at least partially in a gap defined between blade platforms ( 10 ) of at least two adjacent rotating blades ( 12 ), wherein the damping element ( 24 ) is arched radially upward along its axial extent relative to an axis of rotation of the rotor and wherein a sealing element ( 26 ), by means of which an exchange of flow medium in the radial direction between adjacent rotating blades ( 12 ) can be at least reduced thereby, is disposed between at least two adjacent rotating blades ( 12 ) with the sealing element ( 26 ) being disposed radially above damping element ( 24 ).
