Hydrodynamic bearing structure for cooling fan and method for assembling the same
Disclosed are a hydrodynamic bearing structure for bearing a cooling fan and a method of assembling the same. The hydrodynamic bearing structure comprises a housing, a hydrodynamic bearing, a rotation shaft, a thrust member and a bottom plate. The hydrodynamic bearing is mounted in an accommodating space within the housing. The rotation shaft is disposed through a rotation shaft hole of the hydrodynamic bearing. The thrust member is disposed on an end portion of the rotation shaft and accommodated between a bottom surface of the hydrodynamic bearing and a top surface of the bottom plate. A plurality of guiding grooves are disposed in a surface of the thrust member, so that an oil layer applied with pressure is formed on the surface of the thrust member to maintain stable rotation of the rotation shaft and reduce the deflection and vibration of the fan during rotation.
