Abstract: A demister for a gearing system includes a main body having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. First fluid passages extend radially between and through the inner annular rim and the outer annular rim. The first fluid passages include a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.

Abstract: A demister for a gearing system includes a main body shaped as a disk having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. A central opening is defined by the inner annular rim and extends between and through the first wall and the second wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. At least one fluid passage extends radially between and through the inner annular rim and the outer annular rim. The fluid passage(s) includes a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.

Abstract: Planetary gear systems, transmissions, and apparatuses include a plurality of compound planet gears, each having three gear stages, a first non-fixed annular gear, a second non-fixed annular gear, a fixed annular gear, and a non-fixed sun gear. A rotational input to the non-fixed sun gear results in opposite rotational outputs of the first non-fixed annular gear and the second non-fixed annular gear. Compound planet gears and carriers for planetary gear systems are also disclosed.

Abstract: Planetary gear systems, transmissions, and apparatuses include at least one non-fixed annular gear, at least one non-fixed sun gear, at least one compound planet gear meshed between the at least one non-fixed annular gear and the at least one non-fixed sun gear, and at least one fixed gear meshed with the at least one compound planet gear. Rotational input to one of the at least one non-fixed annular gear and the at least one non-fixed sun gear results in an opposite rotational output of the other of the at least one non-fixed annular gear and the at least one non-fixed sun gear.

Abstract: A positive locking overrunning clutch mechanism comprising an inner clutch member, an outer clutch member, and a locking mechanism. The clutch members are adapted to rotate about a clutch axis. The locking mechanism has a plurality of lock portions adapted to transfer torque load from the inner clutch member to the outer clutch member. The locking mechanism is moveable between a locked position and an unlocked position. In the locked position, the lock portions simultaneously engage the inner and outer clutch members in a manner to cause the outer clutch member to rotate with the inner clutch member upon rotation of the inner clutch member about the clutch axis in a first rotational direction. In the unlocked position, the lock portions are positioned relative to the inner and outer clutch members in a manner to permit rotation of the outer clutch member relative to the inner clutch member in the first rotational direction.
