Abstract

A lubrication system (78) includes a first rotating shaft (52) and a second rotating shaft (50). The first rotating shaft (52) and the second rotating shaft (50) are separated by a flowpath (58). The flowpath (58) includes a fluid (72). The fluid (72) is directed towards an outer surface (80) of the first rotating shaft (52). The fluid (72) thereafter moves towards the outer surface (84) of the second rotating shaft (50). The second structure includes a recess (86) configured to collect the fluid (72). The outer surface (80) may include a protrusion (90). The protrusion (90) is configured to direct fluid (72) from the outer surface (80) to the recess (86).
