  • a wind turbine with three-point support of the rotor shaft is for example from DE 10 2006 037 890 B4.
  • a rotor main bearing a winkelein monoes floating bearing, namely a Toroidalrollenlager, provided while a fixed bearing is arranged in a planetary gear, in which the rotor shaft feeds power.
  • a wind turbine with concentric gear / generator arrangement and two-point support of the rotor shaft is known for example from DE 102 42 707 B3.
  • the two-point support is intended here to ensure that aerodynamic loads and mass loads of the rotor are introduced into the tower of the wind turbine without being routed through the gearbox or the generator.
  • the invention is based on the object of specifying a bearing arrangement for a wind turbine with planetary gear, which is characterized both by good mountability and by favorable mechanical stress conditions. Description of the invention
  • the bearing assembly serves to support a planet carrier in a planetary gear of a wind turbine.
  • the planet carrier is rotatably connected to a hollow shaft or integrally formed.
  • the hollow shaft is the main shaft of the wind turbine or a shaft coupled to the main shaft.
  • the main shaft in turn is rotatably connected to the rotor hub, on which the rotor blades of the wind turbine are held.
  • the planetary gear thus represents the only stage or input stage of a single or multi-stage gear arrangement of a wind turbine.
  • the rotating with the rotor speed planet carrier is rotatably mounted in a transmission housing of the wind turbine.
  • planet gears are rotatably mounted on the planet carrier and mesh with an internal toothing, which is located on the inside of the gear housing and is formed either by this housing itself or by a fixedly connected to the transmission housing component.
  • the gear housing thus forms the ring gear of the planetary gear.
  • the planetary gear on a likewise meshing with the planet gears sun gear, which is fixedly connected to an output shaft of the planetary gear or formed in one piece.
  • the front side of the planet carrier, on which the hollow shaft is located, is referred to as the drive-side end face. In the opposite end face is the output side end face of the planet carrier.
  • the bearing of the planet carrier takes place on its two end faces, each with a cylindrical roller bearing.
  • These cylindrical roller bearings absorb radial forces as well as axial forces and tilting moments during operation of the wind turbine. Particularly high forces act on the cylindrical roller bearings when they support at least part of the aerodynamic forces which are conducted via the main shaft.
  • the cylindrical roller bearings of the planetary gearbox have considerable capacity to absorb forces acting in different directions. In this case, a notable tilting moment can be given in particular by means of a gearbox and / or generator arrangement connected on the output side to the planetary gearbox.
  • Each cylindrical roller bearing has an inner ring with two radially outwardly directed rims.
  • Each outer ring has only on its inner, the planet carrier side facing an inboard board, while on the axially outer, ie the planet carrier side facing away from the outer rings no career for the rolling elements, ie cylindrical rollers, limiting board is present.
  • the generator-side that is output-side cylindrical roller bearing, which in a plant constellation in which wind forces and weight forces of the rotor are completely decoupled from the wind turbine gearbox has to absorb a higher radial load than the drive-side cylindrical roller bearing, according to this design also suitable for receiving during operation occurring axial loads .
  • the two cylindrical roller bearings that is the first, drive-side cylindrical roller bearings on the one hand and the second, output-side cylindrical roller bearings on the other hand, are not necessarily exposed to the same axial and radial loads.
  • the drive-side cylindrical roller bearing can be designed to be weaker overall than the output-side cylindrical roller bearing in the said system constellation in which wind forces are decoupled from the cylindrical roller bearing.
  • This design is based on the consideration that for the performance of a cylindrical roller bearing in general, the ratio of axial to radial bearing load is important, with the smallest possible value of this ratio, that is the smallest possible axial force compared to the radial force is sought.
  • that bearing which has to absorb the higher axial forces also has to absorb the higher radial forces.
  • the quotient between axial force and radial force can thus be kept in the same low ranges in both cylindrical roller bearings.
  • the performance of the bearings is better exploitable compared to the prior art. With a tilting of the planet carrier in the gear housing, moreover, in comparison with conventional solutions, lower loads on the drive side cylindrical roller bearings, since sliding contacts between rolling elements and Borden are reduced.
  • the drive-side cylindrical roller bearing has a larger diameter than the generator-side cylindrical roller bearing.
  • a cylinder described by the central axes of all planetary gears rotating with the rotating planet carrier has a diameter which is smaller than the pitch circle diameter of the drive-side cylindrical roller bearing and greater than the pitch circle diameter of the generator-side cylindrical roller bearing.
  • the pitch circle of a cylindrical roller bearing is always defined as the circle defined by the centers of the respective rolling elements.
  • the single board of the outer ring of the first drive-side Zylinderrollenla- gers is preferably supported on a fixed to the transmission housing disc.
  • This disc can be arranged on the inside of the gear housing and fastened by means of studs on the gear housing.
  • This attachment of a stop for the outer ring of the first cylindrical roller bearing forming disc on the transmission housing is preferably integrated in a bearing cap, which is a component of the transmission housing.
  • Another component of the gear housing is a substantially cylindrical housing shell, which concentrically surrounds the axis of rotation of the bearing assembly and connected to the bearing cap, in particular screwed, is.
  • the housing shell carries on its inside directly or indirectly the internal toothing, in which engage the planetary gears of the planetary gear.
  • the gear housing On the output side, the gear housing has a further substantially disk-shaped housing component connected to the housing shell, which has a central opening through which the output shaft of the planetary gear is guided.
  • the axis of rotation of the bearing assembly concentrically surrounding opening of this housing component is bounded by an axially inwardly directed, the planet carrier ring edge of the Gezzausekompo- component.
  • an annular gap is formed, which always remains open during operation of the planetary gear.
  • auxiliary housing part which likewise describes a disk shape and which is located on the inner side, that is to say the side facing the planet carrier, of the housing component having the annular rim.
  • the auxiliary housing part which directly adjoins this has a central opening, which, however, is larger than the opening of the first-mentioned housing component. In the comparatively large opening of the auxiliary housing part of the outer ring of the second cylindrical roller bearing is held.
