发明名称 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.

主权项 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.
