Abstract
A friction bearing of a planetary gearbox, has first and second rotatably connected components. Oil adjacent an oil feed pocket of the first component is directed into the bearing clearance between the components. The oil is directed into the pocket by a first line that opens into the pocket. The profile of the line conjointly with the radial direction of the bearing clearance encloses an angle to direct the oil from the line into the oil feed pocket, the angle being approximately 5°-60° to the radial direction of the bearing clearance and in the main rotation direction of the second component in relation to the first component, or at an angle of approximately 5°-20° to the radial direction of the bearing clearance and in the circumferential direction of the bearing clearance and counter to the main rotation direction of the second component to the first component.
