摘要： A planetary gear arrangement includes a planet carrier assembly defining a sun gear rotation axis for rotatably supporting a plurality of planetary gears about the sun gear rotation axis and a positioning element coupling a first of the planetary gears to the planet carrier. The planetary gear is movable between first and second positions for displacing a rotation axis of the first of the planetary gears relative to the sun gear rotation axis to change load share among the plurality of planetary gears.

摘要： An aircraft rotor system includes a rotating pitch change shaft which rotates about an axis, a translating element disposed within the rotating pitch change shaft and movable along the axis and a pitch change bearing assembly which transfers movement of the translating element to the pitch change shaft. The pitch change bearing assembly includes a primary bearing and a secondary bearing coupled to the rotating pitch change shaft via the translating element when the primary bearing is in a first mode. A thrust shoulder is coupled to the translating element. The thrust shoulder is movable into engagement with the secondary bearing in response to failure of the primary bearing such that in a second mode, movement of the translating element is primarily transferred to the pitch change shaft via the secondary bearing.

摘要： A flexible coupling includes a first disc and a second disc arranged along a rotation axis. The first disc and the second disc each include a radially inner hub portion, a radially outer rim portion, and a diaphragm portion extending between the hub portion and the rim portion. The first disc rim portion is connected to the second disc rim portion and the first disc has a diametral response mode that is different than a diametral response mode of the second disc to limit deformation in the flexible coupling when communicating rotation between a drive member and a driven member connected to one another by the flexible coupling. Drive trains and methods of making flexible couplings are also described.
