Fluid dynamics machine comprising a rotor and a housing

Abstract

A steam turbine having a rotor and a housing is provided herein, wherein the bearing for supporting the rotor is arranged in front of the last vane stage.

1 . A turbomachine, comprising
 a rotor which is mounted rotatably and comprises rotor blades, and   a casing which is arranged about the rotor,   wherein the casing comprises guide vanes, a first bearing and a second bearing for mounting the rotor,   wherein the rotor has, as seen in a flow direction, a first, second, penultimate and a final rotor blade row and the casing has a first, second, penultimate and a final guide vane row, and   wherein the second bearing is arranged in the flow direction between the penultimate and the final rotor blade rows.   
     
     
         2 . The turbomachine as claimed in  claim 1 , wherein the second bearing has a bearing casing and a bearing support formed as guide vanes. 
     
     
         3 . The turbomachine as claimed in  claim 1 , wherein a diffuser is arranged downstream of the final rotor blade row, as seen in the flow direction. 
     
     
         4 . The turbomachine as claimed in  claim 1 , wherein devices for exchanging energy and signals are provided in the bearing support formed as a guide vane. 
     
     
         5 . The turbomachine of  claim 1 , wherein the turbomachine comprises a steam turbine.
