초록

Apparatus for cooling and thermally isolating turbocompressor foil bearings. The bearing journal includes a hollow shaft through which gas is positively circulated to cool the shaft. A slinger at one end of the shaft develops a centrifugal pumping action during operation of the turbocompressor by virtue of a plurality of radially directed gas passages. Pressurized gas may be introduced from the compressor into the interior of the hollow shaft and, after traversing the shaft, returned to the compressor. The invention includes arrangements for protecting t...

청구항

The method of protecting turbomachinery bearings against excessive heat comprising the steps of: forming a bearing of a plurality of pliant foils surrounding a hollow shaft; coupling the hollow shaft to a turbine wheel to be driven thereby; mounting thermal isolating support means in the form of a generally cylindrical intermidiate shaft including a generally radially projecting portion extending between the hollow shaft and the turbine wheel for limiting heat transfer to the hollow shaft from the turbine; and circulating gas through the interior of the ...
