Abstract (en)

[origin: WO2010081468A1] The invention relates to a method for mounting an integral inner ring (10) of a turbocompressor stator to a guide vane ring (12). The method comprises the following steps: making the guide vane ring (12) having an inner radius S available; making the inner ring (10) having an outer radius R available, said outer radius equaling the inner radius S; pretensioning the inner ring (10) to an outer radius r which is smaller than the outer radius R of the untensioned inner ring (10); and relaxing the inner ring (10) to the outer radius R.
