Machine housing

Abstract

A housing ( 1 ) for a machine, in particular a turbomachine, includes a first housing shell ( 2 ) which bears against a second housing shell ( 3 ) along a parting plane ( 4 ). In order to avoid an asymmetric deformation of the housing ( 1 ) when the machine is in operation, in the region of the parting plane ( 4 ) at least one bridge ( 6 ) is formed, by which the two housing shells ( 2, 3 ) are fastened to one another. In this case, the at least one bridge ( 6 ) extends perpendicularly with respect to the parting plane ( 4 ). The bridge ( 6 ) is firmly connected on one side of the parting plane ( 4 ), in a first bridge portion ( 7 ), to the first housing shell ( 2 ) and on the other side of the parting plane ( 4 ), in a second bridge portion ( 8 ), to the second housing shell ( 3 ).

1 . A housing for a machine, the housing comprising: 
 a first housing shell and a second housing shell, the first housing shell bearing against the second housing shell along a parting plane    at least one bridge in the region of the parting plane, the at least one bridge extending transversely with respect to the parting plane and including a first bridge portion and a second bridge portion, the first bridge portion firmly connected on one side of the parting plane to the first housing shell, and the second bridge portion firmly connected on the other side of the parting plane to the second housing shell.    
   
   
       2 . The housing as claimed in  claim 1 , further comprising: 
 at least one screw attaching at least one of the first and second bridge portions to an associated housing shell; or    the firm connection between the first bridge portion, the second bridge portion, or both, to an associated housing shell being configured and arranged for transmission of moments of flexion in the circumferential direction; or    one of the first and second bridge portions being integral with an associated housing shell; or    a positive connection connecting at least one of the first and second bridge portions to an associated housing shell; or    the housing comprising a cylindrical outer contour, and at least one of the first and second bridge portions extending within said cylindrical outer contour; or    a clearance formed on one of the housing shells, at least one of the first and second bridge portions extending within said clearance; or    combinations thereof.    
   
   
       3 . The housing as claimed in  claim 1 , further comprising: 
 at least one contact face formed on at least one of the first and second bridge portions, and at least one contact counterface formed on one of said first and second housing shells, said at least one bridge portion contact face bearing against said at least one contact counterface.    
   
   
       4 . The housing as claimed in  claim 3 , wherein: 
 the at least one bridge is connected to the first and second housing shells so that said at least one contact face is pressed against said at least one contact counterface; or    the at least one contact face, the at least one contact counterface, or both, comprises a surface with an increased coefficient of friction; or    the at least one contact face and the at least one contact counterface comprise form-fitting contours transmitting shear forces and complementary to one another; or    the at least one contact face and the at least one contact counterface extend in a plane which stands, on the parting plane; or    the at least one contact face and the at least one contact counterface extend along a curve which is concave toward the inside of the housing; or combinations thereof.    
   
   
       5 . The housing as claimed in  claim 1 , wherein the two housing shells are fastened to one another in the region of the parting plane solely via the at least one bridge.  
   
   
       6 . The housing as claimed in  claim 1 , further comprising: 
 at least one screw additionally and directly attaching the first and second housing shells to one another in the region of the parting plane.    
   
   
       7 . The housing as claimed in  claim 6 , wherein said at least one screw passes through the parting plane.  
   
   
       8 . The housing as claimed in  claim 1 , 
 wherein the housing is axially symmetrical, cylindrically symmetrical, rotationally symmetrical, or combinations thereof; or    wherein the housing is configured and arranged to be loaded internally or externally with excess pressure, thermally, or both, when in operation; or    both.    
   
   
       9 . The housing as claimed in  claim 1 , 
 wherein at least one of the at least one bridge comprises a plate, having a longitudinal dimension measured in the parting plane and in the longitudinal direction of the housing greater than a dimension measured transversely with respect to the parting plane; or    wherein at least one of the at least one bridge comprises a bar, having a longitudinal dimension measured in the parting plane and in the longitudinal direction of the housing smaller than a dimension measured transversely with respect to the parting plane; or    both.    
   
   
       10 . The housing as claimed in  claim 1 , wherein the first and second housing shells, in the region of the parting plane, and the at least one bridge are configured and arranged to form an at least approximately constant mass distribution over the entire housing circumference.  
   
   
       11 . The housing as claimed in  claim 1 , wherein the machine comprises a turbomachine.  
   
   
       12 . The housing as claimed in  claim 4 , wherein the at lest one contact face and the at least one contact counterface extend in a plane which stands perpendicularly on the parting plane.  
   
   
       13 . The housing as claimed in  claim 4 , wherein the at least one contact face and the at least one contact counterface extend along a curve which is concave toward the inside of the housing and which extends coaxially with respect to a curve of the housing shells in the region of the parting plane.
