Abstract
An epicyclic gear arrangement includes a plurality of substantially axially aligned epicyclic gear trains each having two relatively rotatable output ring gears, a sun input gear and planet gears drivingly connecting the sun and ring gears. Adjacent ends of the ring gears are spaced to permit axial misalignment, the teeth of the planet gears have reducing cross sections in directions away from the planes of their median cross sections to permit effective driving engagement with the ring gears in the event of axial misalignment of the latter, and the sun gears of the gear trains are drivingly interconnected in a manner that permits their axial misalignment. The arrangement is intended for a drive between parts which may flex, as for example an aircraft wing and a control surface thereon.
