  • Publication number: 20090110547
    Abstract: A method for producing a contoured gap between a rotor and a stator of a turbo-engine is provided. A first turbo-engine drives a second turbo-engine by means of a common shaft, the shaft being mounted in a bearing housing by means of a bearing. The aim of the invention is to enable the contoured gap to be created in a simple and reliable manner. To this end, the contoured gap is formed between a contoured surface of the rotor and a contoured surface of an engine housing associated with the rotor, by grinding the contoured surfaces against each other, using the axial play of the bearing.

  • Publication number: 20060008354
    Abstract: The invention relates to a high-speed impeller for delivering gaseous or liquid media, for example as a compressor wheel for an exhaust-gas turbocharger. The high-speed impeller has a reinforcing core structure and an outer functional section. The invention is distinguished by the fact that reinforcing sleeves are pushed concentrically over one another for producing the core structure, in which case the length of the respective reinforcing sleeves varies. Furthermore, the functional section is cast onto the core structure.
