Abstract

A transmission unit (1), particularly for a wind power plant, which has a first planetary stage (2), on the drive input side, a second planetary stage (3) and a third planetary stage (4), on the drive output side, which are coupled with one another in such a manner that a torque from the drive input side can be divided between the first and the second planetary stages (2; 3) and recombined in the third planetary stage (4). The first, the second and the third planetary stages (2; 3; 4) have a common gearwheel carrier (20) which is mounted for rotation about a rotational axis of the transmission unit (1).
