Abstract
A method for manufacturing a hydro dynamic bearing device is provided for the finishing treatment of lubricating oil after lubricating the hydro dynamic bearing device, specifically for properly and effectively wiping off the lubricating oil adhering to the outside of the housing and adjusting the oil-level height of the lubricating oil filled in the housing. The method for manufacturing the hydro dynamic bearing constructed of an axial member housed in a housing, a radial bearing part for supporting the axial member in a non-contact manner in a radial direction by a hydro dynamic pressure action of the lubricating oil generated in a radial bearing clearance, and a sealing part arranged in an opening part of the housing, has the steps of: applying the lubricating oil to an unlubricated hydro dynamic bearing device; and blowing a gas on the outer peripheral surface of the housing, while sucking the lubricating oil from the sealing space of the sealing part or the vicinity thereof using a suction device that generates a negative-pressure suction force.
