摘要： A method to fabricate a fluid bearing spindle includes creating a hollow cylindrical bore through a solid workpiece. The hollow cylindrical bore has a journal bearing portion including first and second distal tapered bearing segments separated by a central bearing segment having a constant radius. Each of the first and second distal tapered bearing segments has a tapered bearing radius that increases with distance from the central bearing segment to a maximum tapered bearing radius that is in the range of 0.5 microns to 1.5 microns greater than the constant radius. Subsequently, a cylindrical spindle shaft is inserted into the hollow cylindrical bore. In an alternative embodiment, a cylindrical outer surface of the spindle shaft includes the tapered bearing segments, rather than the hollow cylindrical bore.

摘要： The invention provides a method for manufacturing bearing assembly. The method comprises: coating a photoresist on an inner wall of a through hole of a bearing; inserting an ultraviolet lamp having a transparent groove pattern thereon into through hole and performing exposure process so as to photosensitize the photoresist corresponding to the groove pattern; removing the ultraviolet lamp and cleaning the photosensitized portion of the photoresist by developer; etching the inner wall not covered with the photoresist by an etchant or forming a deposited layer on the inner wall not covered with the photoresist; removing the photoresist reminding on the inner wall by a stripping agent so as to complete the method for manufacturing a dynamic bearing. The method is also proved to a surface of a shaft to manufacture the dynamic bearing.

摘要： A workpiece has a tribologically useable surface formed as a sliding surface, lubricated by an intermediate material, for a counterpart movable relative to the workpiece in a direction of movement. The sliding surface is provided with a structure formed of a plurality of pockets. The pockets form a closed micropressure chamber delimited by the uninterrupted peripheral rim, respectively. The uninterrupted peripheral rim is a deburred structure edge. In a plan view, the pockets are elongate and have a longitudinal extension. The sliding surface has a functional roughness in the supporting areas between the pockets.

摘要： A bearing manufacturing method for a compressor is disclosed. Since an oxide-coated layer is formed at the surface of the bearing and electrolized in a tiomolybedenic acid ammonium aqueous solution so that the molybedene emulsion can be infiltrated in the fine pores of the oxide-coated layer. Accordingly, the abrasion resistance of the bearing can be increased while the friction coefficient is remarkably reduced, and thus, a reliability of the compressor and an energy efficiency can be increased.
