Abstract: A planetary transmission includes a transfer device for transferring a supply medium. First and second transmission parts rotate relative to one another, with the transfer device having an annular groove on a surface of the first transmission part or of the second transmission part. The transfer device has bores distributed over a periphery. The first transmission part includes a separate bush which points towards the second transmission part and has a sealing groove with a sealing ring axially on both sides of the annular groove. The bush is arranged rotationally fixed on a rest of the first transmission part and designed to float in an axial direction with sufficient play in order to tilt out of a coaxial relative position with respect to the first transmission part and/or to the second transmission part to the extent of a relative movability of the respective sealing ring within the associated sealing groove.

Abstract: A one-piece planetary carrier includes first and second side walls connected to one another by a plurality of webs. At least one of the webs has a curved outer surface which is directed substantially outward in a radial direction and belongs to a lateral surface of the web. The web includes a transition to the first side wall and a transition to the second side wall. The curved outer surface is convexly curved about a first axis of curvature at the transition to the first side wall and the transition to the second side wall. The curved outer surface has at least one anticlastic region which lies in an axial central section and an axial edge section of the web, with a combination of the axial central section with the axial edge section substantially defining an axial dimension of the planetary carrier.
