Abstract

Die Erfindung betrifft einen Verdichterrotor einer Strömungsmaschine, der aufweist: eine Rotorscheibe (21), die um eine Drehachse drehbar ist; eine Rotornabe (22), die den radial äußeren Rand der Rotorscheibe (21) bildet oder mit dieser verbunden ist, und eine Mehrzahl von Laufschaufeln (23), die an der Rotornabe (22) angeordnet sind und sich radial nach außen erstrecken. Die Rotornabe (22) umfasst eine axial vordere Vorderkante (22), eine axial hintere Hinterkante (222), eine Nabenoberseite (223), eine vordere Nabenunterseite (224), die sich auf der Unterseite der Rotornabe (22) von der Vorderkante (221) in Richtung der Rotorscheibe (21) erstreckt und in diese übergeht, und eine hintere Nabenunterseite (225), die sich auf der Unterseite der Rotornabe (22) von der Hinterkante (222) in Richtung der Rotorscheibe (21) erstreckt und in diese übergeht. Es ist vorgesehen, dass die vordere Nabenunterseite (224) und/oder die hintere Nabenunterseite (225) in Umfangsrichtung (ϕ) der Rotornabe (22) derart konturiert ist, dass sie im Bereich unterhalb einer Laufschaufel (23) jeweils eine Einbuchtung (40) ausbildet.

The invention relates to a compressor rotor of a turbomachine, comprising: a rotor disk (21) which is rotatable about an axis of rotation; a rotor hub (22) forming or connected to the radially outer edge of the rotor disk (21) and a plurality of rotor blades (23) disposed on the rotor hub (22) and extending radially outwardly. The rotor hub (22) includes an axially forward leading edge (22), an axially trailing trailing edge (222), a hub top (223), a front hub bottom (224) extending from the leading edge (221) on the underside of the rotor hub (22) ) extends in the direction of the rotor disc (21) and merges into this, and a rear hub base (225) which extends on the underside of the rotor hub (22) from the rear edge (222) in the direction of the rotor disc (21) and merges into it , It is provided that the front hub bottom side (224) and / or the rear hub bottom side (225) is contoured in the circumferential direction (φ) of the rotor hub (22) in such a way that they each have a recess (40) in the area below a rotor blade (23). formed.
