Method for producing a hydrodynamic plain bearing for a spindle motor and a hydrodynamic plain bearing produced using the method

摘要

The bearing manufacturing method has the surface of one of the 2 cooperating rotationally symmetrical bearing parts, which define a concentric and/or coaxial bearing gap, provided with a 3-dimensional structure for providing a hydrodynamic pressure, by application of a uniform thickness coating layer (3), which is partially removed via a high energy machining beam (4), e.g. a laser beam.
