A planetary gearbox includes a planet carrier, with a planetary gear rotatably disposed on the planet carrier, and a gear that meshes with the planetary gear, as well as a gas turbine engine having such a planetary gearbox. The planet carrier has an oil supply installation including a supply line for oil to an opening. The oil is directed out of the opening in the direction of the planetary gear and/or the gear. The oil supply installation in relation to a primary rotating direction of the planetary gear and/or the gear in front of the opening includes a shielding region which protrudes from an external side of the oil supply installation and which by way of the external side of the oil supply installation on a side that faces the primary rotating direction of the planetary gear and/or the gear, delimits an oil collection groove.

Planetary gear and gas turbine engine

A gear with an oil distribution system includes a first area at least approximately rotationally symmetrical with, in its radially inner area, an opening. Via the opening, oil is introduced from a second area into the first area during operation. Downstream of the opening with respect to the second area, the first area includes a collecting area extending in the radial and circumferential directions of the first area. An acceleration appliance for the oil, connected to the first area, is provided in the collecting area so a substantially radial flow direction in the direction of a radially outer area of the collecting area is applied to the oil that is present in the collecting area when the first area rotates. An area of the engine provided downstream of an outlet opening is in or can be brought into operative connection with the main oil supply circuit.
