Beschreibung
Zusammenfassung:	The device has multiple guide blades (3) that are distributed circumferentially with reference to a rotation axis (4) of a turbine wheel (5). A bearing washer (11) is arranged in two parts in radial direction with respect to rotation axis and has an inner ring (13) and an outer ring (14). The rings have a radially opening axial continuous recess (15) for shaft mount (12), in which a shaft (7) is radially inserted. Independent claims are also included for the following: (1) a paddle wheel bearing for rotatable support of guide blades of a varying turbine inlet or compressor geometry of charging device, particularly exhaust gas turbocharger of a vehicle; and (2) a charging device, particularly exhaust gas turbocharger for an internal combustion engine, particular of a vehicle. Die vorliegende Erfindung betrifft unter anderem eine Schaufellagerscheibe (11) zur drehbaren Lagerung zumindest einer Leitschaufel (3) einer variablen Turbinen-/Verdichtergeometrie bei einer Ladeeinrichtung (1), insbesondere bei einem Abgasturbolader für ein Kraftfahrzeug. Eine vereinfachte Herstelcheibe (11) zweiteilig, nämlich aus einem Außenring (14) und aus einem Innenring (13) aufgebaut ist.
