Abstract: A bearing lubrication system for use in a gas turbine engine which utilizes empellers on the drive shaft to pump a lubricant into a lubricant transfer housing. At least one passageway is formed in the transfer housing which directs the lubricant from the pump to a bearing. The lubricant passes through the bearing and thereafter is returned to the pump for the beginning of a new lubrication cycle.

Abstract: A bearing assembly with lubrication and cooling means for a bearing assembly of the type comprising an inner cylindrical ring, an outer cylindrical ring, and a plurality of bearing members disposed intermediate the inner and outer rings to permit rotation of the inner ring relative to the outer ring. An annular groove is formed around one end of the inner ring and a plurality of axial bores extend from the annular groove axially through the inner ring. At least one radial bore extends radially outward from each of said axial bores through the inner ring to provide fluid communication between the annular groove and the bearing members. In operation a lubricant, which is injected into the annular groove, flows through the axial bores in the inner ring. A portion of the lubricant is centrifugally forced through the radial bores to provide lubrication for the bearing members while the remainder of the lubricant flows through the axial bores to cool the bearing assembly.
