Definitions

  • the present invention relates to a power generating device according to the preamble of the subsequent claim 1. It is pre- ferred that the turbine is a wind power turbine, i.e. that the device is suitable for a wind power plant. In particular, relatively high efficient devices with output powers up to several megawatts are intended in that connection.

  • the turbine hub protrudes in a cantilever manner from the rotor, which is mounted in bearings relative to the stator.
  • the turbine hub carries wings, which have a considerable size, and will consequently be subjected to large forces. In particular, these forces result in that the rotor will be subjected to considerable bending deformations, which is accentuated by the cantilever design of the turbine hub from the rotor.
  • Known designs of power generating devices also include directly driven generators where a turbine is connected to the rotor of the generator via a turning moment transmitting axle, the axle being mounted in bearings in relation to a supporting arrangement via a bearing arranged in the vicinity of the turbine and a bearing arranged in the vicinity of the rotor.
