  • Patent number: 11603921
    Abstract: A planetary gear mechanism for a gas turbine engine includes a planet carrier and a planet pin rotationally fixedly connected thereto and on which a planet gear is rotatably mounted via a planet bearing. The planet pin is at least approximately hollow cylindrical in regions. A sleeve in the planet pin comprises an oil feed region through which the bearing is supplied with oil. An outer side region of the sleeve and an inner side region of the planet pin are press fit together. The sleeve has a web radially inside the outer side region. The web extends radially through the sleeve and is fixedly connected to the outer side region in an end region of a main load zone of the bearing, and at the other end is fixedly connected to the outer side region on the opposite side thereof in the radial direction of the sleeve.
