Turbomachine

Abstract

A turbomachine is disclosed. The turbomachine includes a housing and a guide blade ring. An outer shroud of the guide blade ring is divided into segments by joints, where the outer shroud is fastened to the housing by a first fastening element for absorbing axial force and a second fastening element independent of the first fastening element for absorbing circumferential force. The first fastening element and the second fastening elements enable play in a radial direction for the segments of the outer shroud.

         13 . The turbomachine according to  claim 12 , wherein the second fastening element is an annular housing component that projects radially inwardly, wherein the housing component includes a first slot and/or a first nose which meshes with a second nose and/or a second slot, respectively, in a component of the outer shroud that projects radially outwardly. 
     
     
         14 . The turbomachine according to  claim 12 , wherein the first fastening element is disposed in a direction of axial force behind a component of the outer shroud that transmits axial force. 
     
     
         15 . The turbomachine according to  claim 14 , wherein the axial force is transmitted by the component by several separate contact surfaces disposed between the guide blade ring and the first fastening element. 
     
     
         16 . The turbomachine according to  claim 12 , wherein the first fastening element is annular and is positively connected with the housing. 
     
     
         17 . The turbomachine according to  claim 16 , wherein a groove in the annular first fastening element is positively connected with a mounting extension on the housing. 
     
     
         18 . The turbomachine according to  claim 17 , wherein an inside radius of the mounting extension is larger than an outside radius of the outer shroud. 
     
     
         19 . The turbomachine according to  claim 12 , wherein the first fastening element is disposed in a direction of axial force in front of a component of the guide blade ring that transmits axial force. 
     
     
         20 . The turbomachine according to  claim 19 , wherein the first fastening element is radially elastic. 
     
     
         21 . The turbomachine according to  claim 19 , wherein the first fastening element is positively fastened to the housing and to the guide blade ring. 
     
     
         22 . The turbomachine according to  claim 16 , wherein the positive connection is secured by a safety wire. 
     
     
         23 . The turbomachine according to  claim 12 , wherein the turbomachine is a gas turbine. 
     
     
         24 . The turbomachine according to  claim 12 , wherein a movement of the guide blade ring in an axial direction is enableable by the second fastening element. 
     
     
         25 . A method for absorbing forces in a turbomachine, wherein the turbomachine comprises:
 a housing;   a guide blade ring, wherein an outer shroud of the guide blade ring is divided into segments by respective joints;   a first fastening element; and   a second fastening element;   wherein the outer shroud is fastened to the housing by the first fastening element and the second fastening element;   and comprising the steps of;   absorbing an axial force by the first fastening element;   absorbing a circumferential force by the second fastening element; and   radially moving a segment of the outer shroud.
