  • Publication number: 20240125382
    Abstract: A planet carrier assembly includes a rotational axis, a carrier and a carrier flange. The carrier has circumferentially spaced first driver elements formed thereon and the carrier flange has circumferentially spaced second driver elements formed thereon. The second driver elements are interconnected with the first driver elements at common contact areas in an interlocking manner. The carrier flange is axially secured to the carrier in an axial direction by plastically deformed material at the common contact areas. In an example embodiment, the plastically deformed material is displaced from the first driver elements or the second driver elements.
