FOIL TYPE FLUID BEARING

PROBLEM TO BE SOLVED: To provide a foil type fluid bearing capable of stabilizing the revolution in a wider speed range. SOLUTION: A foil assembly of the foil type fluid bearing (1) is constituted of a top foil (5) for fixing one end in a place of the upper half of a stationary hold member and is faced to almost all direction of an outer circumferences of the journal part and a plurality of spring foils (6) on the side of the outer circumference of the top foil (5). And this spring foil is constituted of a resilient member formed by bend processing a connection part (8) to the stationary hold member and a sliding contact part (9) to the top foil and a part of each sliding contact part is installed successively to the circumference by overlaying each other. Thereby, the dimension of every spring foil can be shortened and a high rigidity one can be manufactured in a low cost comparatively. Moreover, the compliance of the individual spring foil can be raised appropriately because the load of a revolving body is dispersed and received by the many spring foils. COPYRIGHT: (C)2004,JPO&NCIPI
