Abstract

A gearbox assembly (46) includes a planet gear (106) including an outer surface (144) and an inner surface (140) opposite the outer surface (144). A pair of circumferential oil channels (136) are formed in the inner surface (140) proximate opposite ends of the planet gear (106). A distributor channel (138) is formed to extend in a longitudinal direction toward a center of the planet gear (106) from each circumferential oil channel (136). One or more tooth channels (142) are formed to extend from each distributor channel (138) to the outer surface (144) of the planet gear (106). A journal pin (112) is received within the planet gear (106) extending along an axis (13) about which the planet gear (106) rotates. A gap (132) defines a journal bearing (133) formed between the inner surface (140) of the planet gear (106) and the journal pin (112). An internal bore (114) is formed in the journal pin (112) extending from an end of the journal pin (112) to the gap (132).
