ABSTRACT:
A turbine engine including an oil flow path through the low pressure system shaft which, as compared to at least one known oil flow path, facilitates increasing the rated torque and life of the low pressure system shaft is described. In one embodiment, the lubrication opening in the low pressure shaft is oriented so that with respect to a plane along which an outer surface of the low pressure shaft substantially extends, the center axis of the lubrication opening is substantially normal to the plane. As a result of this configuration, the stress concentration in the low pressure shaft at the location of the lubrication opening is substantially reduced. In addition, such a lubrication opening is relatively easy to form as compared to the known, angularly oriented lubrication shaft. Further, the lubrication opening in the present configuration can have a larger diameter than the known angularly oriented lubrication opening due to the reduced stress concentration, and such a larger lubrication opening facilitates more free flow of lubrication through the opening to the differential bearing.
