A transmission unit (), particularly for a wind power plant, which has a first planetary stage (), on the drive input side, a second planetary stage () and a third planetary stage (), 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 () and recombined in the third planetary stage (). The first, the second and the third planetary stages () have a common gearwheel carrier () which is mounted for rotation about a rotational axis of the transmission unit ().

Gearbox unit with gear carrier

A wind turbine gear mechanism with a planetary gear stage arranged on the drive input side and with first and second spur gear stages arranged, in a gear mechanism housing, downstream of the planetary gear stage. The first spur gear stage rotationally and functionally connects a sun gear shaft of the planetary gear stage to an intermediate shaft, the second spur gear stage rotationally and functionally connects the intermediate shaft to a drive output shaft, and only one intermediate shaft is provided. In this case, the gear mechanism housing has a separation joint along which the gear mechanism housing can be divided into a main housing portion and a housing cover in such manner that a separation joint plane passes through the central axis of the intermediate shaft and the separation joint plane extends a distance away from the central axis of the sun gear shaft.
