ABSTRACT:
A lubrication system (40, 60) for an integrated drive generator in accordance with the present invention includes a source of pressurized oil; a carrier (12), rotatably mounted on a axis of rotation, having an inlet (32) for receiving pressurized oil from the source and an outlet (38) for discharging a mixture of oil and air, and rotatably supporting a plurality of planetary gears (14) as the carrier rotates; a plurality of first ports (26), each port being associated with a different planetary gear for supplying only oil to a journal (31) rotatably supporting the associated planetary gear upon rotation of the carrier when pressurized oil is supplied to the inlet, each first port being disposed at a radial position on the carrier at a point displaced from the axis of rotation; and a deaerator (42), in fluid communication with a mixture of air and oil moving radially outward from the axis of rotation during rotation of the carrier to each of the first ports, for removing air from the oil so that only oil moves radially outward to the first ports and for discharging a mixture of oil and air at the outlet.
