Charging device |
摘要 |
A charging device may include a shaft rotatably mounted on at least one slide bearing in a shaft bearing region. At least one flow opening for introducing and discharging a fluid may be defined on the shaft bearing region, wherein the shaft in the shaft bearing region may have two outer portions each running in a circumferential direction and axially binding an inner portion. At least one of the outer portions on its surface may include at least one microstructure. |

1. An exhaust gas turbocharger, comprising:
a shaft rotatably mounted in a bearing housing via at least one radial slide bearing, the shaft being mounted on the at least one slide bearing in a shaft bearing region; at least one flow opening for at least one of introducing and discharging a fluid defined on the shaft bearing region; wherein the shaft in the shaft bearing region has two outer portions each running in a circumferential direction and axially binding an inner portion; wherein at least one of the outer portions includes a surface comprising at least one microstructure, the microstructure including a depth that runs asymmetrically along a structure line, the depth having an axial component and a circumferential component, wherein the axial component runs parallel to an axial direction of the shaft and the circumferential component runs along a circumferential direction of the shaft. |
