  • Vacuum fill/assembly method for fluid dynamic bearing motor
    Patent number: 6305439
    Abstract: A single step shaft assembly and oil fill process begins with the sleeve and thrust plate being assembled, leaving open the entire shaft cavity. The assembly is then placed in an evacuation chamber, and air is evacuated. A measured amount of oil or hydrofluid is then placed in the shaft cavity. The shaft is then inserted in the shaft cavity and pressed or otherwise inserted into an opening in the thrust plate. When this is done, the oil will disperse throughout the bearing fluid gap and cavity. When properly measured, no oil will exit the cavity.
