Abstract

A drive train of a fluid flow power plant, in particular of a wind power plant or of a tidal power plant, includes a rotor hub that bears at least one rotor blade and a transmission that has a plurality of planetary stages. The transmission is configured to transmit a rotational movement of a rotor shaft connected to the rotor hub to a drive of a downstream generator in a stepped-up fashion. The rotor hub, the transmission, and the generator are arranged coaxially with respect to one another. The transmission is embodied as a power-split transmission with three planetary stages so as to form a suitable transmission ratio of a rotational movement of the rotor shaft on the drive of the generator in a compact fashion.
