ABSTRACT:
A web unit for planet gear sets for the mounting of planet gears including a first web element and a second web element, which are tightly connected and can be tensioned in axial direction by transmission or connecting elements progressing in axial direction and describing a theoretical connecting axis. Each transmission or connecting element has regions of differing radial dimensions, the front faces of the regions, thus formed and facing the individual web elements, form a first and a second contact surface, resting either directly or through an intermediate element against the contact surfaces in contact regions, formed by the front faces of the web elements facing each other. At least one element forming a contact surface of a contact region includes a profile. The profile is characterized in the radially external region by at least one region of greater axial extension in the direction of the theoretical connecting axis.
