20090250296Lubrication and scavenge system - A lubrication and scavenge system for a gas turbine, capable continued operation in nose-down or nose-up orientations, has a number of oil drainage passages to return oil to one or more collection chambers adjacent a rolling element bearing. A rotary impellor in the chamber forces the oil into a scavenge off-take passageway in the chamber wall leading to a scavenge pump. However, in some orientations windage effects in the chamber can return the oil to the drainage passage rather than permitting the impellor to centrifuge it into the off-take passageway. As a result oil starvation may occur. To avoid this and improve scavenging a shield is located between the drainage path and the off-take passageway adjacent to a face of the impellor. The shield may comprise an additional member, but preferably is formed integrally with a bearing race so as to ease assembly.10-08-2009
