MANUFACTURING METHOD FOR DYNAMIC PRESSURE BEARING DEVICE AND DYNAMIC PRESSURE BEARING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a dynamic pressure bearing device capable of injecting proper quantity of lubricating oil into a bearing unit in a simple process without leaving air bubbles inside the bearing unit and the dynamic pressure bearing device. SOLUTION: The bearing unit 20 is exposed under a reduced pressure atmosphere of a vacuum chamber 9 and air at a gap between a shaft body and a bearing is discharged. Proper quantity of lubricating oil 7 is dropped to an open end 20a of a gap of the bearing unit 20 by a dispenser 10. The bearing unit 20 is opened to the atmosphere and lubricating oil 7 is filled into the gap of the bearing unit 20.
