Abstract
A lubrication system is for a planetary gear system of the type which includes an input shaft for driving an output shaft through a planetary gear reducer. The system includes an oil pump driven by the input shaft to provide lubricating oil to the input shaft bearings and a first chamber defined by a running seal between a ring gear wheel on the input shaft and the housing. A passage through the ring gear wheel allows lubricating oil to be received from the first chamber to a second chamber which is generally defined by a second annular running seal between the ring gear wheel and the planetary carrier. Passages through the planetary carrier allow delivery of the lubricating oil under pressure from the second chamber to the planetary gears and the sun gear.
