A method and apparatus are provided for lubricating a sun gear 32 connected to a hollow coupling shaft 30 which is adapted to be joined to a source of rotational energy. The shaft 30 defines at least one opening 90 intermediate its ends which is adapted to receive a source 92 of lubricating fluid under pressure periodically throughout the rotational cycle of the shaft. By damming 108 the periphery of the opening on the interior of the shaft 30, the film of lubricating fluid formed along the interior surface of the shaft by centrifugal force is precluded from draining out of the opening 90 when that opening is not supplied with lubricating fluid under pressure. Channels 142 are provided across the walls 96 of the shaft to distribute the lubricating fluid thereformed axially towards the sun gear 32. Means 102 are also provided on the interior of the shaft 30 to axially distribute the entering oil and to preclude oil entering the opening from being discharged across the shaft and out of another opening which is not aligned with a source of lubricating fluid. |
