摘要： 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.
