Abstract
A baffle (78) encircles a planetary mechanism (10) having a ring gear element (18), a sun gear element (20), a planet carrier element (22) and a plurality of planet gear elements (24), and is connected to a stationary support (30, 48, 50, 66). The baffle (78) includes wiping means (90) for wiping fluid from one of the elements (18, 20, 22, 24) in response to rotation thereof and directing fluid that would otherwise cause high drag losses radially away from the planetary mechanism (10).
