GAS BEARING

PURPOSE:To secure the jointing of a foil and improve the effect of mass production by a method wherein a flexible foil provided in the circular space between a rotating shaft and a static bearing member is integrally jointed with a bearing base and formed as a spot welding is possible. CONSTITUTION:In case of the assembling of a gas bearing, firstly, a bearing base 1 is integrally formed with a ring part 2 and a supporting part 3, and a jointing surface 6a of a foil 6 is made flush with a jointing surface 7 of the supporting part 3. Secondly, a sliding surface 6b of the foil 6 is arranged at the designated position, the foil 6 is fixed to the supporting part 3. Subsequently, a cutout part 8 of the bearing base 1, that is, a foil fixing piece 12 is engaged into the space between the adjacent supporting parts 3, the piece 12 is fixed to the ring part 2 with clamping members 13, 14. Thus, the assembling is finished after an elastic element 19 is inserted into a hollow chamber 18 formed in the bearing base 1 from the side surface of the bearing base 1. Thereby, the foil 6 is integrally jointed with the bearing base 1, accordingly, the expected purpose can be achieved.
