ABSTRACT:
A shroud for a gear train (12) includes a plurality of meshing gears (14), each gear (14) having sides (14a, 14b), teeth (16) and an outer diameter (14c). The shroud (10) includes a curvilinear enclosure (20) for encircling the outer diameter (14c) of each gear (14) within the gear train (12) and for enclosing the sides (14a, 14b) adjacent to the outer diameter (14c) of each gear (14) within the gear train (12). The enclosure (20) includes a pair of side walls (20a, 20b) and an end wall (20c). The end wall (20c) includes first (36) and second (38) ports associated with ones of the plurality of gears (14) in the gear train (12), such that the first port (36) allows for cooling fluid to be injected into the enclosure (20) and the associated second port (38) allows for cooling fluid to be ejected from the enclosure (20). The enclosure (20) side walls (20a, 20b) further include a port (30) adjacent to the area where ones of the plurality of gears (14) mesh for allowing intake and discharge of cooling fluid and air from the enclosure (20).
