Title:
FLUID BEARING AND LUBRICATING OIL FILLING METHOD OF FLUID BEARING
Document Type and Number:
Japanese Patent JP2008309339
Kind Code:
A
Abstract:
To provide a fluid bearing without causing nonuniformity for generating dynamic pressure, by surely filling a predetermined space with lubricating oil, by surely removing bubbles in the lubricating oil being a viscous fluid for generating the dynamic pressure.
This method comprises: an illustrated process (Fig.1(B)) of exhausting air inside of a bearing in advance by decompressing an environment around an assembly where the lubricating oil 25 is injected; and an illustrated process (Fig.1(C)) of pressing and filling the viscous fluid in the predetermined space by gradually returning the environment of the assembly to atmospheric pressure thereafter.
