A bearing assembly (10) for a supercharging apparatus (500). A bearing assembly (10) includes a bearing housing (400) and a shaft (530). The bearing assembly (10) further includes a compressor-side bearing bush (100) and a turbine-side bearing bush (200), which together support the shaft (530) within the bearing bore (410) of the bearing housing (400). The bearing assembly (10) is configured to supply unequal amounts of lubricant to a compressor-side outer lubrication gap (115) of the compressor-side bearing bush (100) and to a turbine-side outer lubrication gap (215) of the turbine-side bearing bush (200). The bearing assembly (10) is further configured to supply unequal amounts of lubricant to a compressor-side internal lubrication gap (113) of the compressor-side bearing bush (100) and to a turbine-side internal lubrication gap (213) of the turbine-side bearing bush (200). A supercharging apparatus including the bearing assembly is also disclosed. 一种用于增压设备(500)的轴承组件(10)。轴承组件(10)包含轴承壳体(400)和轴(530)。轴承组件(10)进
