<p>The rotor (1) has a vibration reducing unit (2) designed such that it damps vibrations of the rotor, where the vibrations are developed during operation of a turbo-machine. The vibration reducing unit is provided with a housing (3), and a path surface (4) is formed inside the housing. The vibration reducing unit has a rolling body (5) e.g. ball and cylinder, in the housing, where the rolling body is movably arranged on the path surface. The path surface is curved convex relative to a rotational axis of the rotor.</p> |
