摘要： A ring gear arrangement, including: a ring gear mount including: a ring gear having at least one internal gear for interaction with one or more gear wheels; a ring gear stator; and, a plurality of couplings which locate the ring gear within the gear stator, each coupling having a drive arm connected to the ring gear and a resiliently deformable connection, wherein the drive arm is movable between a first position in which the ring gear is in a rest position and a second position in which the ring gear has undergone some radial or rotational movement relative to the ring gear stator, wherein movement of the drive arm from a the first position to the second position loads the resiliently deformable connection against the ring gear, wherein the resiliently deformable connection biases the drive arm to return to the first position when in the second position.
