| 摘要 |
The invention relates to a bearing arrangement for a shaft (3) of a turbine wheel (2) or of a turbine wheel (2) and of a compressor wheel (4), wherein—the turbine wheel (2) is driven by the exhaust gas of a vehicle drive unit, said bearing arrangement comprising—a static housing (9), which—together with a bearing bushing (10) arranged in a rotationally movable manner relative to the housing (9)—encloses a first bearing gap (11), wherein—the bearing bushing (10) accommodates the shaft (3) in a rotationally movable manner and encloses a second bearing gap (12) together with the shaft. The invention is characterized in that a ratio (R1/R2) of radii (R1, R2) of the first bearing gap (11) and of the second bearing gap (12) with respect to a rotational axis (14) of the shaft (3) changes at least once over the maximum axial extent (x) of the bearing bushing (10). |
