856,375. Fluid bearings. GENERAL ELECTRIC CO. March 10, 1958 [March 25, 1957], No. 7581/58. Class 12 (1). [Also in Group XXVI] A pressurized air bearing between relatively rotatable members such as the rotor 13, Fig. 2, and casing 10 of a turbine or compressor is formed by supplying high-pressure air to a chamber 19 constituted by a compartmented element 15, 16 mounted on one or other of the members. As shown, the compartmented element, of thin sheet-metal, is in the form of an annular channel 15 mounted within one or more additional channels 16, and is secured such as by welding, to the tips of the blades 20 of the rotor 13 so that it extends into a recess 11 to within a small clearance of the wall of the casing. If sufficient high-pressure air is supplied through a pipe 17, which may be located in the rotor 13 or in the casing 10, as shown, an air bearing may thereby be formed which enables the normal bearing for supporting the rotor shaft to be dispensed with. The channel elements 15, 16 may be replaced by a honeycomb-type structure 21, Fig. 3. |
