Abstract
A gearbox assembly for use in a gas turbine engine includes a gearbox housing and first and second shafts. The first shaft is rotatably mounted in the gearbox housing. The first shaft has a first set of splines and defines a central cavity. The second shaft has a second set of splines engaged with the first set of splines. A scupper is positioned on an inner surface of the gearbox housing proximate the first shaft so as to direct liquid from the scupper through the central cavity of the first shaft to the first and second sets of splines.
