TURBO ENGINE ROTOR COMPRISING A BLADE-SHAFT CONNECTION MEANS, AND BLADE FOR SAID ROTOR
In a turbo engine, the rotor includes a shaft, blades, and a shaft-blade connection. The shaft blade connection can be provided as a fir tree connection, having a fir tree blade root and fir tree shaft grooves receiving the blade roots. The blade roots can include lobes, while the grooves can includ...

| description | In a turbo engine, the rotor includes a shaft, blades, and a shaft-blade connection. The shaft blade connection can be provided as a fir tree connection, having a fir tree blade root and fir tree shaft grooves receiving the blade roots. The blade roots can include lobes, while the grooves can include undercut recesses receiving the lobes. The inclined mating bearing surfaces provided on a shaft post or on a lobe, respectively, are offset with respect to each other in the circumferential direction while partially overlapping. Each bearing surface is tangentially adjoined by a convexly curved end of bedding surface. |
