Turbine i.e. axial turbine, for use in exhaust-gas turbocharger to turbocharge large diesel engine, has diffuser divided into two segments in circumferential direction, where side of each segment is extended in radial direction

摘要

The turbine (1) has a multipart turbine housing (4), a rotor (2) and a diffuser (3) that is divided into two segments (3A, 3B) and/or into multiple pieces in a circumferential direction. A circumferential side (3C) of each segment is extended in a radial direction. A cover ring is detachably screwed to the housing and/or the diffuser. The segments of the diffuser are connected with the housing and/or the cover ring. Independent claims are also included for the following: (1) a method for assembling and/or disassembling of a diffuser of a turbine (2) a method for producing a diffuser (3) an exhaust-gas turbocharger comprising a compressor.
