  • Asymmetric gear teeth
    Patent number: 11156285
    Abstract: A gear train includes a first gear having teeth meshed with teeth of a second gear. Each tooth of the first gear includes a coast side and a drive side opposed to the coast side. The drive side has a pressure angle that is greater than that of the coast side. The gear train can be part of a powertrain system for a rotorcraft, and can replace a traditional gear train in a retrofit or new build. The first gear is a planet gear and the second gear is a ring gear wherein the planet gear and ring gear are in a planetary gear train configuration.

  • Planetary gear sets for power transmissions
    Patent number: 10233997
    Abstract: 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.

  • Split torque gearbox
    Publication number: 20050132833
    Abstract: A split torque gearbox having multiple input shafts. Each input shaft is connected to two face gears. Each face gear is connected to two quill shafts, one is coaxially mounted and the second is not coaxially mounted. Of the two quill shafts, one is positioned on a first side of an output stage and a second quill shaft is located on a second side of the output stage and the quill shafts are connected thereto. The output stage is connected to a main shaft.
