摘要： A fluid dynamic bearing system having at least one stationary part and one rotating part that form a bearing gap filled with bearing fluid between the opposing bearing surfaces, at least one end of the bearing gap being open and sealed against the environment by a sealing means, pumping grooves being provided on at least two spatially separated bearing surfaces to generate hydrodynamic pressure and at least one supply volume connected to the bearing gap being available for the bearing fluid. The distinctive feature of the invention is that the sealing means are formed by pumping grooves that are disposed at the open and of the bearing gap on at least one of the bearing parts and designed in such away that they generate a pumping action on the bearing fluid directed towards the interior of the bearing and, as a result, create a dynamic seal for the open end of the bearing. The bearing system itself is designed as a compact unit preferably consisting of only three parts.

It comprises a stationary part consisting of a cup-shaped housing and a bearing bush disposed therein, a moving part consisting of an arrangement of a shaft and a hub rotatably accommodated in the bearing bush and a thrust plate disposed at one end of the shaft that is accommodated in an annular disk-shaped space formed by the housing and 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. The bearing system further comprises at least one radial bearing formed by the outer surface of the shaft and the inner surface of the bearing bush and associated hydrodynamic bearing patterns, a first axial bearing formed by a first end face of the bearing bush, an opposing end face of the hub and associated hydrodynamic bearing patterns, and a second axial bearing formed by a second end face of the bearing bush, an opposing end face of the thrust plate and associated hydrodynamic bearing patterns.

摘要： The invention relates to a fluid dynamic bearing system having pressure-generating asymmetric surface patterns, having at least two bearing parts that are rotatable with respect to each other and form a bearing gap filled with a bearing fluid between associated bearing surfaces. The surface patterns are disposed on at least one bearing surface so that hydrodynamic pressure is generated within the bearing gap when the bearing parts rotate with respect to each other. According to the invention, each surface pattern comprises at least three sections, each section generating a pumping action in a defined direction, and the pumping actions of adjacent sections being substantially aligned in opposite directions. Due to the special geometry of the surface patterns according to the invention, tolerances in the geometry of the bearing gap have a less significant effect on the pre-defined pumping direction.
摘要翻译： 本发明涉及具有产生压力的不对称表面图案的流体动力轴承系统，其具有至少两个相对于彼此可旋转的轴承部分，并且在相关联的轴承表面之间形成填充有轴承流体的轴承间隙。 表面图案设置在至少一个支承表面上，使得当轴承部件相对于彼此旋转时，在轴承间隙内产生流体动力学压力。 根据本发明，每个表面图案包括至少三个部分，每个部分在确定的方向上产生泵送作用，并且相邻部分的泵送动作基本上沿相反方向排列。 由于根据本发明的表面图案的特殊几何形状，轴承间隙的几何形状的公差对预定义的泵送方向具有较小的显着影响。
