Filed: 2001-12-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic fluid bearing preventing the leakage of fluid, enabling a twin-support structure, rotating in both directions, and saving a cost.  <P>SOLUTION: This magnetic fluid bearing 1 is composed of a bearing housing 3 made of non-magnetic material, a shaft 2 made of non-magnetic material, a magnet 5 fitted in a periphery of the shaft, and a magnetic fluid 6 held so as to generate magnetic levitation force. The magnetic fluid is held between an outer peripheral surface and upper and lower surfaces of the magnet and an inner wall of the bearing housing. The magnet fluid is prevented from scattering due to magnetic force of the magnet, and the twin-support structure of the shaft is enabled. The bearing housing is kept at a constant position and posture by magnetic levitation force of the magnetic fluid. Therefore, machining a shaft groove of a conventional dynamic pressure bearing is not required, so that the bearing can be manufactured at a low cost, and can be rotated in right and left directions. The bearing of this invention can be applied to various rotating shafts for a blower and the like, but especially preferable for a spindle of an HDD.  <P>COPYRIGHT: (C)2003,JPO
