ASYMMETRICAL FLUID BEARING

摘要

PROBLEM TO BE SOLVED: To provide an asymmetrical fluid bearing having simple construction for increasing the load capacity of the fluid bearing and reducing the loss of the bearing. SOLUTION: The radial fluid bearing has a cutout portion on part of a single side for bearing an asymmetrical shaft which gives asymmetrical load thereto during rotation. The fluid bearing also has a cutout portion which gives asymmetrical load thereto, on the bearing surface. The bearing surface on the counter load side where a cutout is provided is formed narrower than the bearing surface on the load side where the cutout is not provided. In this case, the cutout is formed extending from the side of the fluid bearing into the bearing surface of the fluid bearing, or the cutout is formed at the middle of the fluid bearing. The asymmetrical fluid bearing is used for a precise control steady seismic source. COPYRIGHT: (C)2006,JPO&NCIPI
