Hydrodynamic bearing.

摘要

A hydrodynamic bearing apparatus for supporting a rotating member on a support shaft (10) provided on a stationary member through a radial hydrodynamic bearing (12) and a thrust hydrodynamic bearing (13), the apparatus comprising a magnetic member (26) provided on the rotating member; and a magnet provided on the rotating member opposing the magnetic member (26) provided on the stationary member; whereby the magnetic member (26) is attracted by the magnetic force from the magnet so that a force acting on the thrust hydrodynamic bearing (12) are cancelled or reduced.
