ABSTRACT:
A lubricating distribution apparatus for a rotating shaft assembly has a shaft member rotatably supported in a pair of spaced housings. Each housing has formed therein a pocket in which a dam member is secured. A tube member has ends thereof secured to each dam member and extends axially through a passage formed in the rotating shaft. Lubrication fluid is introduced into the system between at least one of the housings and one of the dam members for lubrication fluid flow through said tube member to the other dam member. Lubrication flow between the dam members and the housings is distributed to other portions of the mechanism as well as through restricted passages toward the rotating shaft member.
