  • Integrated oil transfer sleeve and bearing
    Patent number: 6758598
    Abstract: An integrated roller bearing and fluid transfer sleeve adapted for supporting and transferring fluid to a rotating shaft in a gas turbine engine reduction gearbox. The integrated roller bearing and fluid transfer sleeve comprises a fluid transfer sleeve having a sleeve casing defining therein an annular fluid plenum open radially outwardly, and at least two spaced apart roller bearing assemblies each comprising an annular outer race integral with the sleeve casing and each assembly comprising a plurality of roller elements supported by the outer race. Each roller bearing assembly is disposed within the sleeve casing, one at each opposing end thereof, and the plurality of roller elements in each assembly define a first inner diameter substantially equal to an outer diameter of the rotating shaft adapted to be supported by the roller elements.
