Abstract
A bearing device having a boundary layer of pressurized gas comprises an enclosed member of a box type, which has a semi-cylindrical surface of a semi-circular shape in its transverse cross section. The enclosed member has a plurality of minute holes in the aforesaid semi-cylindrical surface, which holes are directed towards the imaginary center of the aforesaid semi-cylindrical surface, and a pressurized air inlet provided in one wall of the enclosed member. A boundary layer of pressurized air is formed between the semi-cylindrical surface and an outer surface of a rotary shaft mounted thereon due to the injection of air therebetween through a plurality of minute holes defined in the semi-cylindrical surface of the enclosed member. Thus, the rotary shaft is supported by the pressurized air thus introduced, so that the rotary shaft may be rotated in a stable condition, with its center of rotation in coincidence with the imaginary center of the aforesaid semi-cylindrical curved surface.
