Tubular housing for a turbomachine

Abstract

A tubular housing for a turbomachine is provided. The tubular housing includes two half-tube shells which, lying against one another in two connecting regions overlap partially in each case in the tangential direction of the tubular housing. In order to specify a particularly reliable and permanent connection of the two half-tube shells which additionally develop a particularly satisfactory sealing action, it is proposed that, in order to interlock the half-tube shells in the tangential direction, in relation to the tube axis of the housing, at least one eccentric pin is provided in one or both connecting regions.

         10 . A tubular housing for a turbomachine, comprising:
 two half-tube shells which, when in mutual abutment in two connection regions, overlap in each case in a tangential direction of the tubular housing; and   an eccentric bolt provided in one or both connection regions for tensioning the half-tube shells in the tangential direction with respect to a tube axis of the housing, the eccentric bolt including a head for turning the eccentric bolt, an eccentric section and a shaft section,   wherein the eccentric section is arranged in the connection region in one of the two half-tube shells, and the shaft section is arranged in the connection region in the other of the two half-tube shells, and   wherein the shaft section or the eccentric section is mounted in a compensating element, which is mounted such that it is displaced axially but is fixed in rotation in or relative to one of the two half-tube shells.   
     
     
         11 . The housing as claimed in  claim 10 , wherein the two half-tube shells are tensioned radially with respect to the tube axis of the housing in the respective connection region by means of a screw connection. 
     
     
         12 . The housing as claimed in  claim 11 , wherein at least two screw connections which are adjacent in a circumferential direction are provided in each connection region. 
     
     
         13 . The housing as claimed in  claim 10 , wherein a plurality of eccentric bolts are distributed along a axial direction in the respective connection region. 
     
     
         14 . The housing as claimed in  claim 10 , wherein a lever is fastened to the eccentric bolt the ends of which lever being in each case articulated to a rod assembly for the synchronous adjustment of the eccentric bolt. 
     
     
         15 . The housing as claimed in  claim 10 , wherein the respective connection region comprises a sealing region, in which is situated a sealing means for sealing off an internal housing space with respect to an external space. 
     
     
         16 . The housing as claimed in  claim 10 , wherein the housing varies in diameter along an axial direction of the housing. 
     
     
         17 . A guide vane carrier for a turbomachine, comprising:
 a tubular housing as claimed in  claim 10 .   
     
     
         18 . An outer housing for a stationary compressor or for a stationary turbine, comprising:
 an axial section which is designed as a tubular housing as claimed in claim  1 .
