摘要 |
The invention relates to a fluid dynamic bearing system. It comprises a stationary part consisting of a cup-shaped housing and a bearing bush disposed therein, and a moving part consisting of an arrangement of a shaft and a hub rotatably accommodated in the bearing bush. The respective surfaces opposing each other of the stationary part and the moving part are spaced apart from each other by a bearing gap filled with bearing fluid. At least one radial bearing is provided that is formed by the outer surface of the shaft and the inner surface of the bearing bush and associated hydrodynamic bearing patterns. An axial bearing is formed by an end face of the bearing bush, an opposing end face of the hub and associated hydrodynamic bearing patterns. The shaft is held by a flange disposed at one of its ends that is accommodated in an annular disk-shaped space formed by the housing and the bearing bush.
