Definitions

  • Bearing housing for the storage of the rotor shaft of a wind turbine
  • the invention relates to a bearing housing for supporting the rotor shaft of a wind power plant, with a cylindrical portion for receiving the rotor shaft and fastening means for fastening the bearing housing to the wind turbine.
  • the double shaft bearing takes place, for example, within the hub, is integrated in the gearbox or in the machine carrier and designed in the form of two separate bearing housings or combined in a bearing housing.
  • Object of the present invention is therefore to provide a bearing housing for the storage of the rotor shaft of a wind turbine, which can be very compact and simple, with a good load transfer and a simple, not labor-intensive installation in the wind turbine should be possible.
  • the basic idea of the invention is to provide the fastening means for fastening the bearing housing to the wind turbine in the region of the horizontal center line of the wind turbine cylindrical portion of the bearing housing to the cylindrical portion or to the rotor axis to arrange axially parallel.
  • the fastening means which are preferably designed as feet, are arranged approximately at the horizontal height of the axis of rotation of the rotor shaft, resulting in a very good introduction of force into the machine carrier of the wind energy plant.
  • the dominant lateral rotor forces can namely be introduced into the machine carrier in a straight line, without the housing generating additional tilting moments.
  • the position of the housing feet in the region of the center line of the cylindrical portion allows a "sagging" of the lower half of the housing, which ensures a uniform load distribution on the rotor bearings.
  • the bearing housing consists of two in the middle plane of the cylindrical portion releasably interconnected shells.
  • an advantageous construction of the bearing housing is achieved in particular when the lower shell is particularly preferably designed as part of the machine carrier of a wind energy plant.
  • a simple and quick installation of the bearing can be achieved with rotor shaft, without the need for complex tools or a special review of the connection of the fastener.
  • the fastening means are preferably arranged symmetrically to the vertical center line of the cylindrical portion and may be formed as feet or as a flange.
  • the fastening means should be vertically deviating in a region of the center line or in the region of the center plane of approximately + 25% of the diameter of the cylindrical section, particularly preferably ⁇ 10% of the diameter of the cylindrical section (ie between a lower vertical limit of 10%. the cylinder diameter below the center line and an upper vertical limit of 10% of the cylinder diameter above the center line).
  • the bearing housing preferably has one or more plain bearings.
  • the bearing housing is a cylindrical roller bearing and a double row Tapered roller bearing, as this allows a radially as well as axially absolutely backlash-free rotor bearing.
  • the previous use of spherical roller bearings namely has the disadvantage that the rotor shaft design can always move a few millimeters axially, with axially occurring shocks are very harmful to the transmission. This disadvantage can now be eliminated with the bearing housing according to the invention.
  • Fig. 1 is a perspective view of the bearing housing according to the invention.
  • FIG. 3 shows a perspective view of a machine carrier with rotor shaft, bearing housing, gearbox and generator according to the invention.
  • Fig. 4 shows a cross section through the rotor shaft receiving erfmdungswashe bearing housing.
  • Fig. 1 shows the bearing housing according to the invention in a perspective view.
  • the bearing housing 10 has a cylindrical portion 20 for receiving the rotor shaft 80 (not shown here).
  • the fastening means 30 arranged externally on the bearing housing 10 for fastening the bearing housing 10 to a wind power plant can be seen to be arranged axially parallel in the region of the horizontal center line of the cylindrical section 20.
  • the fastening means 30 are here preferably designed as feet. However, the two feet each shown on one side of the bearing housing 10 may also be connected to each other axially parallel, so that the fastening means form a flange.
  • FIG. 2 shows a front view of the bearing housing 10 according to the invention, which in the present example is arranged on a machine carrier 50. It can be clearly seen that the fastening means 30 are arranged in the region of the horizontal center line of the cylindrical portion 20.
  • bearing housing 10 consists of two in the region of the median plane of the cylindrical portion releasably interconnected shells.
  • the lower shell is formed as part of the machine carrier.
  • FIG. 3 shows a perspective view of a machine carrier 50, on which the bearing housing 10 according to the invention, which is provided in front of the transmission housing 90, receives the rotor shaft 80.
  • FIG. 4 shows a cross section through the bearing housing 10 according to the invention, in which a double-row tapered roller bearing 70 paired with a cylindrical roller bearing 60 is accommodated.
  • the tapered roller bearing as well as the cylindrical roller bearing do not allow compensation of misalignment and angular errors, so that the maintenance of the required tolerances make installation in a common housing necessary.
  • the introduction of force into the machine carrier is ensured by the well-illustrated in the other drawings arrangement of the fastening means in the region of the horizontal line of the cylindrical portion.
  • the resulting from the invention advantages are the significantly better power flow design on the machine frame in relation to bearing housings, which are designed for example as a pillow block unit. Furthermore, the production and assembly of the bearing housing according to the invention compared to the known from the prior art bearing housings less expensive. In particular, a coupling of the bearing housing with the transmission is not necessary.
