Abstract:
A vane arrangement (1) of a turbo machine (4), in particular of a gas turbine, includes at least one vane carrier (2) attached to a housing (5) of a turbo machine (4), and several vanes (3) attached to the vane carrier (2) and circumferentially arranged side by side, wherein the attachment between the vane carrier (2) and respective vane (3) is adapted for being axially pluggable. In order to simplify dismounting of a single vane (3) at least one of the vanes (3) is provided with an extraction device (35) having at least one axially extending extraction through-hole (36). The respective extraction through hole (36) is provided with an inner thread (37), and the vane carrier (2) is provided with an abutment zone (38) axially opposing the extraction through hole (36). The extraction device (35) is adapted for inducing axially oriented extraction forces into the respective vane (3) by an extraction tool, which is provided with an outer thread and which is in order to extract the respective vane (3) from the vane carrier (2) inserted into the extraction through-hole (36) and axially pressing against the abutment zone (28).
