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.The invention relates to a rotor (3) for a turbomachine,
with a hollow shaft (13) which is arranged coaxially with respect to its axis of rotation and which is supported on both sides on two axially opposite sections of the rotor (3) and encloses an inner cavity (51). In order to specify a rotor (3) for a turbomachine, which has a longer service life and a lower susceptibility to mechanical defects, it is proposed that the hollow shaft in the axial direction of the rotor (3) of several adjacent rings (43) is formed and that the rings (43) against each other and with respect to the portions of the cavity (51) to seal the outside.
Ferner betrifft die Erfindung eine Strömungsmaschine mit solch einem Rotor (3). Furthermore, the invention relates to a turbomachine with such a rotor (3).
