Abstract
A friction bearing of a planetary gearbox has a first rotationally fixed component and a second component rotatably connected thereto. Oil in the region of an oil feed pocket of the first component is directed into the bearing clearance between the components. The oil is directed into the oil feed pocket via at least one first line that opens into the oil feed pocket. Oil is also directed via at least one second line into the oil feed pocket, the port region of said second line into the oil feed pocket in the circumferential direction of the bearing clearance and in the main rotation direction of the second component in relation to the first component and/or in the axial direction of the friction bearing being spaced apart from the port region of the first line into the oil feed pocket.
