PURPOSE:To improve the stability at a high speed in rotation of a shaft, by interposing a plate-shaped spring foil between the supporting surface of a bearing case and the reverse side of a bearing member and alternately arranging spacers with a suitable space on both sides of the foil. CONSTITUTION:A plate-shaped spring foil 12 is interposed between a supporting surface 9 of a bearing case 5 and the reverse side of a bearing member 13 the right side of which is used as a bearing face 17. Then spacers 7, for placing the spring foil 12 afloat from the supporting surface 9 and the bearing member 13, are alternately arranged with a suitable space on both sides of the spring foil 12. In this way, the pressure generated in the bearing face 17 of the bearing member 13 in the direction of its thickness acts on the spring foil 12 through the spacers 7, causing the displacement of the bearing member 13 in the direction of its thickness by elastic deformation of the spring foil 12. Accordingly, a fixed quantity, being capable for the rigidity against a load, enables the bearing to be most suitably designed, thus the stability at a high speed in rotation of a shaft can be as high improved as possible. |
