ABSTRACT:
A bearing housing1is designed to accommodate a bearing4within its outer walls3. The bearing4upon rotation generates a centrifugally dispersed oil spray from its peripheral edge7and this spray is collected upon a facing surface of the wall3. An out-take6has a relatively wide chordal arc opening across which a baffle8is presented such that there is a spaced opening10between a leading edge9of the baffle and a portion3aof the housing1. In such circumstances oil is scavenged from adjacent to the inner surface of the wall3in order to facilitate oil flow through the bearing4and out of the housing1such that it has a reduced residence time within the bearing4/housing1and so is less susceptible to temperature induced degradation.
