Abstract:
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 unwinding the inner ring in the guide vane ring by relaxing the inner ring to the outer radius R; wherein for pre-tensioning the inner ring, a die plate having a radius whose outer radius is smaller than the outer radius R of the untensioned inner ring minus its radial thickness is used.
