Abstract: An embergency lubrication mist system is operable in response to a drop in oil pressure in a primary lubrication system for components inside a casing. An emergency oil reservoir provides a head of oil for discharge through an air activated misting nozzle sized to dispense an oil in a mist for fogging the inside of the casing and coating the components inside. The misting nozzle has an air passageway normally closed to a source of air and opening to operate the emergency system in response to a drop of pressure in the primary lubricating system.

Abstract: A shroud (20) for a gear train (12) disposed within a gear case (22) includes a plurality of meshing gears (14), each gear (14) having sides (14a, 14b), teeth (16) and an outer diameter (14c). The shroud (20) encircles 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 shroud (20) includes a pair of side walls (20a, 20b) and an end wall (20c). The walls (20a, 20b, 20c) enclosed the teeth (16) of each of the gears (14) within the gear train (12) for substantially minimizing cooling fluid present within the gear case (22) from contacting the gear train (12).

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).
