<p>A self-scavenging, hybrid lubrication subsystem for a main transmission gearbox includes a sump that is fabricated as an integral structural extension of the gearbox so that the dynamic fluid level of the lubricating medium in the sump is a predetermined distance above the bottom (18) of the gearbox. The radial discontinuity between the cylindrical (22) and throat segments (26) in combination define a nozzle inlet (28) that is operative to direct outflow of the lubricating medium collected in the bottom of the gearbox to another sump with higher fluid level by means of a nozzle (60). The interaction between the peripheral surface of the rotating annular planetary carrier plate and the structurally-modified side wall of the gearbox exerts a viscous pumping action on the lubricating medium in the flow channels causing the lubricating medium to flow therethrough and being transported through the nozzle (60) to a higher level.</p> |
