  "abstract": "A planetary transmission has a collecting groove for a lubricant and a planetary gear set having a planetary support rotatable around a planetary gear set axis of rotation in relation to a housing of the planetary transmission, planetary gears rotatably mounted on the planetary support, and a ring gear meshing with the planetary gears. The transmission has a disc coupling having an inner disc support connected to the collecting groove in a rotationally fixed manner, an outer disc support connected to the housing of the planetary transmission in a rotationally fixed manner, and a set of friction discs. The inner disc support is connected to the ring gear in a rotationally fixed manner. The ring gear and/or a cylinder portion connected to the ring gear in a rotationally fixed manner has a first lubricant channel running radially with respect to the planetary gear set axis of rotation.",
