PURPOSE:To make a bearing optimum as one for a high speed rotating body by spirally inserting a metallic sheet having metallic wires fixed on its one surface between a housing and a rotating shaft, and fixing the outside end of the metallic sheet to the housing. CONSTITUTION:A metallic sheet 3 having plural metallic wires 2 fixed on its face is spirally inserted into an annular gap 5 between the inner periphery of the housing 1 and a rotating shaft 4 inserted into the housing 1 to fix the outside end of the sheet 3 to the housing 1. Thus the most inside face of the sheet 3 comes into contact with the outer peripheral face of the shaft 4 to function as a bearing face, and a fluid film is formed between the bearing face and the surface of the shaft 4 during its rotation to perform bearing action. The sheet 3 therefore functions as the optimum bearing for a high speed rotating body. |
