| description | In a turbo engine, the rotor comprises a shaft, blades, and a shaft-blade connection means. The shaft blade connection means is provided in particular a fir tree connection, comprising a fir tree blade root and fir tree shaft grooves receiving the blade roots. The blade roots comprise lobes (260), while the grooves comprise undercut recesses receiving the lobes. The inclined mating bearing surfaces (161, 261) provided on a shaft post (150) or on a lobe (260), respectively, are offset with respect to each other in the circumferential direction (U) while partially overlapping. Each bearing surface is tangentially adjoined by a convexly curved end of bedding surface (162, 262). |
