Rotor blade arrangement of a turbomachine

摘要

Abstract A rotor (1) of a turbomachine has an encompassing slot (2) with a fir tree profile. This slot (2) accommodates root sections (4) of rotor blades (5) and also filler pieces or spacers (3) which are arranged between circumferentially adjacent root sections (4). The filler pieces (3) have complementary fir tree profiles in such a way that the filler pieces (3) are fixed in a form-fitting manner in the slot (2) in the radial direction of the rotor (1). The root sections (4) of the rotor blades (5) are connected to the filler pieces (3) by means of shoulders (40) which project from the root sections (4) and are radially supported on an underside of the filler pieces (3).
