<p>A lubrication arrangement for interlocking gears 2, 3 is configured by a housing 1 which incorporates sections la, lb of a snail cross-section. Thus, rotating gears 2, 3 are positioned to generate a centrifugal pumping effect between those gears 2, 3 and the housing sections la, lb which drives scavenged oil flow into a volute 11 formed by the opposing surface of the housing la, lb. The scavenged oil is driven in the direction 13 towards an off- take 12 configured such that there is a minimum available cross-sectional area 14 between the housing at the intermeshing of the gears 2, 3 at an interlocking location 4. In such circumstances the scavenged oil is driven at relatively high speed through the off-take 12. Such relatively high speed scavenged oil 15 can be used for displacement scavenging in other parts of an engine or machine where problems exist with oil residence.</p> |
