TURBOMACHINE COMPRISING A STATOR VANE SUPPORT AND METHOD OF MOUNTING STATOR VANES TO THE STATOR VANE SUPPORT

摘要

Disclosed is a turbo machine which comprises vanes (14,16) which extend radially at the same angle distance in relation to a rotor (3) and which are provided with outer legs (27) forming a vane ring (15). The legs (27) of the vanes are maintained on an annular vane support (18) which comprises an inner peripheral groove (21) with undercuts (24) which engage with the legs (25) of the vanes from the rear. Fixing means are provided between the vane support (18) and the legs (27) of the vanes, pressing the legs (27) of the vanes against the undercuts (24). The fixing means comprise at least one groove-shaped recess (26) extending in the bottom of the groove (25) along the periphery thereof and several annular pressing segments (30) which are arranged therein and which press against the legs (27) of the vanes in a pre-tensed manner.
