Zusammenfassung:A planetary gear train including a ring gear defining a central axis; a plurality of planet gears, each planet gear being rotatable about a respective planet axis and meshing with the ring gear, and each planet gear including a conical and helical planet gear toothing defining a conical direction; a planet carrier rotationally supporting the planet gears for rotation about the planet axes, the planet carrier being axially displaceable along the central axis; and a carrier forcing device arranged to force the planet carrier along the central axis in the conical direction. A gearbox for an industrial robot, the gearbox including a planetary gear train, and an industrial robot including a planetary gear train or a gearbox, are also provided.
