Abstract
A static lubricant supply system within a gearbox that delivers lubricant to rotating gears. The lubricant supply system includes a stationary sleeve assembly for delivering the lubricant to a rotating receiver member, shaft, or flange. The sleeve assembly includes bearings, seals, jets, and plenums. The jets are skewed to deliver lubricant in the tangential direction of rotational motion of the receiver member, shaft, or flange. In the radial gap transfer configuration, the sleeve assembly circumscribes the receiver member or shaft. A race in the receiver member or shaft receives the lubricant. Channels within the receiver member, shaft, and gears deliver lubricant to the gears. In the axial gap transfer configuration, the sleeve assembly transfers lubricant to a flange attached to a receiver member. The flange has a race that receives the lubricant from the jets. Channels within the flange, receiver member, and gears deliver lubricant to the gears.
