Abstract
Official abstract text for this publication.
A method for mounting an integral inner ring ( 10 ) of a turbocompressor stator to a guide vane ring ( 12 ) comprises the following steps: -Providing the guide vane ring ( 12 ) with an inner radius S; -Providing inner ring ( 10 ) with an outer radius R, which corresponds to the inner radius S; -Pre-tensioning inner ring ( 10 ) to an outer radius r that is smaller than the outer radius R of the untensioned inner ring ( 10 ); and -Relaxing inner ring ( 10 ) to the outer radius R.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for mounting an integral inner ring of a turbocompressor stator to a guide vane ring having the following steps: providing the guide vane ring with an inner radius S; providing the inner ring with an outer radius R, which corresponds to the inner radius S; pre-tensioning the inner ring to an outer radius r, which is constant over the periphery of the inner ring and which is smaller than the outer radius R of the untensioned inner ring; and…
