  • Epicyclic gear system and gas turbine engine
    Patent number: 11401985
    Abstract: An epicyclic gear system for a gas turbine engine includes a planet carrier with at least one structural member, on which a planet gear is pivot-mounted by a bearing that is radially arranged between the planet gear and the structural member. Furthermore, a roller bearing device is arranged radially between the planet gear and the bearing. A relative movement between the planet gear and the bearing is prevented by the roller bearing device, if a friction torque in the region of the bearing is less than or equal to a threshold value.
    Type: Grant

  • Carrier structure for an epicyclic gear drive, epicyclic gear drive and turbo engine with an epicyclic gear drive
    Patent number: 10260619
    Abstract: A carrier structure for an epicyclic gear drive is provided. The carrier structure includes carrier elements connected with at least one planet gear and the first carrier element is connected with the second carrier element through at least two struts with the at least two struts having an inclination angle of more than 20° in the direction of a rotation around a rotation axis of the carrier structure.
