Abstract
A system for the distribution of atomized lubricating fluid includes a cylindrical ring placed upstream from an intershaft bearing of an inner shaft. The outer surface of the ring forms part of a labyrinth joint. Within the ring are cells open on the upstream surface of the ring, into which flows pressurized air. In the downstream end of each cell is an atomizing orifice directed toward the bearing. In the radially inner wall of each cell is an approximately radial bore. These bores cooperate with the means supplying lubricating fluid, which comprise radial bores in the wall of the inner shaft and emptying into a groove provided on the inner surface of the inner shaft. The groove receives lubricating fluid through fixed tubing that passes through the interior of the inner shaft.
