Groove structure on bearing surface of fluid dynamic bearing, has bearing fluid which is conveyed in flow direction through groove structure, and bearing surface faces another bearing surface, where bearing gap is filled with bearing fluid
摘要
<p>The groove structure (11) comprises a bearing fluid which is conveyed in a flow direction (24) through the groove structure by a movement of a bearing surface (10) relative to the other bearing surface. The depth of the groove structure is constant or decreases in the flow direction or in a pump direction (25) of the bearing fluid. The bearing surface faces another bearing surface, where a bearing gap filled with a bearing fluid, is arranged between the bearing surfaces. An independent claim is included for a method for applying a groove structure.</p>
