An apparatus for lubricating power transfer components is described. The apparatus includes a first shaft enclosed by a housing with a main cavity, and an inboard bearing and an outboard bearing supporting the first shaft. An inboard bearing cavity and an outboard bearing cavity surround, respectively, the inboard and outboard bearings. Lubrication fluid flows from an entrance port in the housing, through a flow passage within a wall of the housing to the inboard bearing cavity, through a flow passage within the first shaft from the inboard bearing cavity to the outboard bearing cavity, and through an overflow port in a wall of the outboard bearing cavity. A second shaft provides rotational power to the first shaft (e.g., via an idler gear). A lubrication deflector, such as a frustoconical deflector, surrounds a portion of a second shaft and extends into the main cavity of the housing. |

1. A lubrication apparatus for lubricating one or more power transfer components, the lubrication apparatus comprising:
a first shaft enclosed, at least in part, by a housing having a first cavity; an inboard bearing rotatably supporting the first shaft; an inboard bearing cavity surrounding, at least in part, the inboard bearing; an outboard bearing rotatably supporting the first shaft; an outboard bearing cavity defined, at least in part, by a first internal flange of the housing, the outboard bearing cavity surrounding, at least in part, the outboard bearing; an entrance port to the housing, the entrance port being in fluid communication with a lubrication fluid flow source; a first flow passage, contained within a wall of the housing, and extending from the entrance port to the inboard bearing cavity; a second flow passage, contained within the first shaft, and extending from the inboard bearing cavity to the outboard bearing cavity; and an overflow port through the first internal flange of the housing, the overflow port extending between the outboard bearing cavity and the first cavity; wherein lubrication fluid from the lubrication fluid flow source flows into the entrance port and through the first flow passage, fills the inboard bearing cavity, flows through the second flow passage to the outboard bearing cavity, and drains from the outboard bearing cavity through the overflow port and into the first cavity. |
