Abstract
Die Erfindung bezieht sich auf eine Leitschaufeleinrichtung, insbesondere einer Variablen Turbinengeometrie (VTG) für eine Aufladeeinrichtung, insbesondere eines Abgasturboladers, mit einem Turbinenlaufrad (10). Dem Turbinenlaufrad (10) ist eintrittsseitig eine Anzahl von Leitschaufeln (28, 40) vorgeschaltet, die an einem Schaufelkranz (24) aufgenommen sind. Die Leitschaufeln (28, 40) sind um eine Drehachse (36) zwischen einer geschlossenen Position (50) und einer offenen Position (52) verstellbar. Die Leitschaufeln (28, 40) sind in Bezug zur Drehachse (36) in einer Exzentrizität (42) aufgenommen. The invention relates to a guide vane device, in particular a variable turbine geometry (VTG) for a supercharging device, in particular an exhaust gas turbocharger, with a turbine wheel (10). The turbine runner (10) is preceded on the inlet side by a number of guide vanes (28, 40), which are received on a blade ring (24). The vanes (28, 40) are adjustable about an axis of rotation (36) between a closed position (50) and an open position (52). The vanes (28, 40) are received in an eccentricity (42) with respect to the axis of rotation (36).
