Drive train of a fluid flow power plant

摘要

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.

1. A drive train of a continuous-flow power plant, comprising:
a rotor hub carrying at least one rotor blade; and a gear mechanism having a plurality of planetary stages, the gear mechanism being configured to effect stepped-up transmission of a rotary movement of a rotor shaft connected to the rotor hub to a drive of a downstream generator, wherein the rotor hub, the gear mechanism, and the generator are disposed coaxially with respect to one another, wherein the gear mechanism is configured as a power-split gear mechanism having three planetary stages, and wherein the rotor shaft is mounted via a main bearing in a surrounding support structure to which a gear mechanism casing configured to hold the gear mechanism is connected on both sides via torque brackets.
