<P>PROBLEM TO BE SOLVED: To provide a leaf-shaped foil bearing capable of acquiring high rotation accuracy, and capable of coping with higher rotation. <P>SOLUTION: The foil bearing 10 comprises: a cylindrical outer member 11; a shaft 6 inserted into the internal periphery of the outer member 11; leaves 14 arranged in a plurality of points in the circumferential direction between an inner peripheral surface 11b of the outer member 11 and an outer peripheral surface 6a of the shaft 6. A region including the front end 14a of each leaf 14 forms a top foil Tf having a bearing face 14c, and forms a back foil Bf for supporting, from the backside, the top foil of the leaf to which a region including the rear end 14b of each leaf 14 adjoins. Either or both of the front end 14a and the rear end 14b of each leaf 14 are inclined with respect to the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
