Abstract

An assembly includes a first planetary stage, a second planetary stage, and at least one retainer plate. The first planetary stage has a planet carrier and the second planetary stage has a ring gear. The planet carrier and the ring gear are configured to be rotated about a common axis of rotation. The retainer plate is attached to the ring gear and engages in a groove in the planet carrier. The groove and the axis of rotation are at least partially skewed to each other. The retainer plate is arranged at least partially on a first side of a first plane and on a first side of a second plane. The first plane and the second plane intersect along the axis of rotation. All planet bolts fixed in the planet carrier each lie on a second side of the first plane and/or the second plane.
