ジヤーナル軸受。 Inside the shaft hole of the bearing case, which has a cylindrical shaft hole,
A band-shaped elastic foil is wound and attached, and a rotating shaft that is fitted into the inner peripheral surface of the attached elastic foil is rotated by an air flow introduced into a wedge-shaped gap created between the elastic foil and the elastic foil. In a foil journal bearing that is supported while floating, the band-shaped elastic foil is stacked with a plurality of strip-shaped elastic pieces of the same shape that are shifted from each other in the longitudinal direction, and the inner circumferential surface of the elastic foil is mounted. A foil journal bearing characterized in that a multi-arc portion is formed to form a plurality of wedge-shaped gaps between the bearing and the outer circumferential surface of the rotating shaft.
