Abstract

Die Erfindung betrifft einen Rotor (3) für eine Strömungsmaschine,
mit einer zu seiner Drehachse koaxial angeordneten Hohlwelle (13), welche sich beidseitig stirnseitig an zwei axial gegenüberliegenden Abschnitten des Rotors (3) abstützt und einen inneren Hohlraum (51) umschließt. Um einen Rotor (3) für eine Strömungsmaschine anzugeben, der eine höhere Lebensdauer und eine geringere Anfälligkeit gegenüber mechanischen Defekten aufweist, wird vorgeschlagen, dass die Hohlwelle in Axialrichtung des Rotors (3) aus mehreren aneinanderliegenden Ringen (43) gebildet ist und dass die Ringe (43) gegeneinander und gegenüber den Abschnitten den Hohlraum (51) nach außen abdichten.
Ferner betrifft die Erfindung eine Strömungsmaschine mit solch einem Rotor (3).
