Abstract
The invention relates to a method and a device for mounting an axial turbo-machine, preferably a low-pressure compressor for a gas turbine, constructed without a parting line with a whole or constructed rotor. From the design point of view, problems arise regarding the mounting of the stationary guide vane rings in the case of a design without a parting line and a whole rotor. The problem is solved by dividing the guide vane rings into sectors in a number greater than two. These sectors are brought radially into position and are guided and fixed in the correct position by guide rings which are applied around each guide vane ring composed from sectors. Each composed guide vane ring with the surrounding guide ring is guided and fixed to the preceding guide ring and all the guide vane rings are successively built up around the whole or constructed rotor. The guide rings mounted together constitute a stiff annular element.
