Abstract

See full text

A system is presented for directing the flow of cooling fluid in a rotational machine having co-axial rotatable shafts. The system comprises a first shaft rotatable about an axis, a second shaft rotatable about the axis and having a portion axially overlapping with the first shaft, and a fluid catcher. The fluid catcher is coupled between the first shaft and the second shaft. The fluid catcher comprises a first interface region interfacing with the first shaft, a second interface region interfacing with the second shaft, a fluid retention lip at least partly defining an oil capture region; and a body. The body is coupled to the oil retention lip and defines a channel in fluid communication with the oil capture region. The channel is positioned to direct fluid to one of the first interface region or the second interface region.
