Estimating the term…
A planetary gear box for a gas turbine engine, has a planet carrier with a carrier element and a planet gear. The planet gear is mounted rotatably via a plain bearing on the carrier element. An oil feed pocket is provided in the region of an outer side of the carrier element, via which feed pocket oil can be passed into a bearing gap between the outer side of the carrier element and an inner side of the planet gear. In the circumferential region of a main load direction of the plain bearing, the carrier element is formed with at least one channel carrying transmission oil. The channel extends in the carrier element radially inside the outer side of the carrier element, extending in the axial direction of the carrier element, and includes a cross section closed with respect to the bearing gap.
A planetary gear box for a gas turbine engine, having a planet carrier and having at least one planet gear, which is mounted rotatably by means of a plain bearing on a carrier element connected to the planet carrier in a manner precluding relative rotation, wherein at least one oil feed pocket ) is provided in the region of an outer side of the carrier element, via which feed pocket oil can be passed into a bearing gap between the outer side of the carrier element and an inner side of the planet gear,
A plain bearing for a planetary gear box, in particular for a planetary gear box of a gas turbine engine of an aircraft, having a static axle and a component part rotatably mounted thereon, wherein at least one oil feed pocket is provided in the region of an outer side of the axle, via which feed pocket oil can be passed into a bearing gap between the outer side of the axle and an inner side of the rotatable component part,
