A planetary gearbox includes a first planetary stage with a component, a sun gear, and a planet gear meshing with the sun gear via a toothing system, a second planetary stage, and a lubricant transfer device arranged between the first planetary stage and the second planetary stage. The lubricant transfer device includes a discharge component arranged in a co-rotating manner on a component of the second planetary stage, and a receiving component designed to receive lubricant and arranged in a co-rotating manner on the component of the first planetary stage. A lubricant conduit communicates with the lubricant transfer device and is configured to extend over an entire axial extent of a tooth engagement region of the sun gear of the first planetary stage radially within the toothing system of the sun gear with the planet gear of the first planetary stage.
