Beschreibung
Zusammenfassung:	Rotor for turbomachines with shrouded blades comprising a row (3) of blades (4) covered by an external ring (5), coaxial to said row (3) of blades (4); the external ring (5) being composed of a plurality of sectors (6), commonly referred to as shrouds, which are adjacent to one another and transversely and circumferentially attached to the end of respective blades (4); a damping member (16) being arranged so as to straddle a respective pair of adjacent sectors (6a, 6b) and being pushed, in use, against radially internal surfaces (13) of the sectors (6) of the pair of adjacent sectors (6). L'invention concerne un rotor pour turbomachines à aubes carénées qui comprend une rangée (3) d'aubes (4) couvertes par un anneau extérieur (5), coaxial par rapport à ladite rangée (3) d'aubes (4); l'anneau extérieur (5) est constitué d'une pluralité de secteurs (6), appelés ordinairement carénages, qui sont mutuellement adjacents et fixés de manière transversale et circonférentielle à l'extrémité des aubes (4) respectives; un élément amortisseur (16) placé de manière à chevaucher deux secteurs adjacents (6a, 6b) respectifs est poussé, à l'utilisation, contre des surfaces (13) radialement internes de deux secteurs (6) adjacents.
