Abstract (en)
The device has fastening units (50) for fastening support rings (40) of a guiding device at a gas outlet housing (20). The support rings include bearing points (46) for receiving guide vane-shafts (42). The bearing points are radially arranged within a radius (r1), and the fastening units are radially arranged beyond a radius (r2), where the former radius is smaller than the latter radius. Rotatable guide vanes (41) are unevenly distributed along a circumference of the guiding device, where the guide vanes are in different distances to each other.
Abstract (de)
Die Befestigung für den Anbau der Leitvorrichtung (40) am Gasaustrittsgehäuse (20) wird in dem Bereich radial ausserhalb der Leitschaufeln (41, 42) positioniert. Damit kann die Umfangsposition der Leitschaufeln innerhalb der vorgegebenen Winkel frei gewählt werden. Es entstehen keine Kollisionen zwischen den Leitschaufeln (41, 42) und den Befestigungsmitteln (50).
