ABSTRACT:
A lubrication system with a lubricant feeding device disposed in the housing of a speed change mechanism for auxiliary devices. The lubricant flows from a central lubricant reservoir within the speed change mechanism through the moving surfaces to the inner surface of the housing due to centrifugal force. Excess lubricant is returned to the lubricant reservoir by the lubricant return device. If a planetary gear mechanism is used, the lubricant return force is provided by the meshing action of the pinion gears with the primary power transmission gear and an outer ring gear. The lubricant flow is directed by lubricant guide walls which substantially enclose said meshing portions and direct the lubricant to lubricant return passages. Examples of lubricant return passages include radially formed passages through the root of the primary power transmission gear and having communication with said internal lubricant reservoir or a recessed face on the primary power transmission gear and having communication with the internal lubricant reservoir. Fins may be formed about the speed change mechanism housing to provide increased cooling of the lubricant collected on the internal surface thereof.
