Rotating shaft scavenging scoop

A scavenge system for a bearing assembly, the system comprising a scavenging passage extending axially through a rotating shaft supported by the bearing assembly, and means provided on the rotating shaft for drawing oil radially inwardly towards a central axis of said rotating shaft and into said scavenging passage as said shaft rotates.

A scavenge system for a bearing assembly, the system comprising a scavenging passage extending axially through a rotating shaft supported by the bearing assembly, and at least one scoop provided on the rotating shaft, said at least one scoop impelling oil internally of said rotating shaft into said scavenging passage as said at least one scoop rotates with said rotating shaft, further comprising a number of conduits in fluid communication with an oil cavity communicating with the bearing assembly, the conduits defining a plurality of circumferentially aligned openings in an annular inner surface closely surrounding an outer surface of the rotating shaft, wherein there is provided at least two angularly spaced-apart inlet passages in the rotating shaft between the scoops, each of the inlet passages being defined such as to alternately be aligned with each of the plurality of openings during a rotation of the shaft, the rotation of the shaft creating an interaction between aligned inlet passages and openings such that used oil flowing from the conduits is drawn from the openings to the inlet passages, so as to flow through the scavenge passage axially of the rotating shaft.
