Centrifugal compressor

Abstract

A centrifugal compressor includes a housing having a part joint plane which extends parallel to or along a machine axis, and a shaft extending along the machine axis and having a first shaft end and a second shaft end. At least one impeller is mounted on the shaft. A collector helix is arranged downstream of the at least one impeller and collects the compressed fluid prior to an outflow into a following machine module. The collector helix is arranged on the first shaft end. A drive is arranged on the first shaft end. An axial intake at an overhang stage of the centrifugal compressor is provided on the shaft on the second shaft end. The collector helix is realized as a single piece in the circumferential direction and is flanged to the housing of the centrifugal compressor.

1 - 2 . (canceled) 
     
     
         3 . A centrifugal compressor for compressing a fluid, the centrifugal compressor comprising:
 a housing which has a part joint plane which extends parallel to or along a machine axis,   a shaft which extends along the machine axis and has a first shaft end and a second shaft end,   at least one impeller which is mounted on the shaft,   a collector helix which is arranged downstream of the at least one impeller and collects the compressed fluid prior to an outflow into a following machine module, wherein the collector helix is arranged on the first shaft end, and   a drive which is arranged on the first shaft end,   wherein an axial intake at an overhang stage of the centrifugal compressor is provided on the shaft on the second shaft end,   wherein the collector helix is realized as a single piece in the circumferential direction and is flanged to the housing of the centrifugal compressor.   
     
     
         4 . The centrifugal compressor as claimed in  claim 3 , wherein the collector helix is realized as support of a radial bearing for the bearing arrangement of the shaft.
