Abstract

PURPOSE: To prevent a rotating shaft from whirling by a method wherein the inside circumference surface of a bearing metal is composed of a combination of cylindrical surfaces which have two or more different centers of curvature.
CONSTITUTION: A rotating shaft 4 is inserted into a bearing metal 5 which has two symmetrical and cylindrical inside circumference surfaces. The minimum clearance between the outside circumference surface of the rotating shaft 4 and the inside circumference surface of the bearing metal 5 is set at 2W3μ. This constitution makes it possible to form dynamic pressure bearing portions with a wide range in two places, upper and lower, and to maintain the rotating shaft 4 at a high precision.
