20090110547 | Method for producing a contoured gap, and turbo-engine comprising contoured gap - 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. | 04-30-2009 |
