Title: Dynamic pressure fluid bearing
Inventor: ASAI HIROMITSU
IPC: F16C17/04
Filed: 1990-09-28
Abstract: PURPOSE:To restrain generation of abraded powder and elongate the life of a bearing by forming a lubricating film made of a porous aluminium oxide film impregnated with lubricant on a bearing surface having a dynamic pressure generating groove in a dynamic pressure fluid bearing and making the bottom surface of the dynamic pressure generating groove of aluminum or aluminum alloy. CONSTITUTION:The surface of a shaft 1 is covered with a lubricating film 4 of a porous aluminum oxide impregnated with lubricant on portions except for a groove 3 for generating dynamic pressure. Aluminum or aluminum alloy itself is left exposed on the bottom surface 3a of the dynamic pressure generating groove 3. A dynamic pressure fluid bearing is light since a shaft 1 formed with the dynamic pressure generating groove 3 is made of aluminum or aluminum alloy, so that a radial load and thrust load acting on the bearing are small. As a result, the wear of a dynamic pressure radial fluid bearing R and dynamic pressure thrust fluid bearing S is few to improve durability.
