Fluid dynamic bearing system for pivot bearing of motors, particularly spindle motor for fixed disk drive or blower, has fixed bearing components where shell of components forms angle between zero to ten degree with rotation axis

摘要

The fluid dynamic bearing system has fixed bearing component (10) where shell (52) of the components forms an angle between 0 degree to 10 degree with the rotation axis (16). The shell (56) of the movable bearing component (12) forms another angle between 0 degree to 10 degree with the rotation axis in area of the sealing gap (48). The two angles open in the same direction.
