Abstract
A planetary transmission system is disclosed. In an example, the system may include a planet gear, an outer bearing, and a planetary gear pin including an inner bore fluidly coupled to an outer bore, wherein the outer bore is narrower in diameter than the inner bore and a difference in diameter therebetween allows oil flow by gravity from the inner bore to the outer bore and reduces oil from flow from the inner bore to the outer bore, wherein oil exits the inner bore via a plurality of holes fluidly coupling the inner bore to the outer bearing without valves.
