Definitions

  • the invention relates to a wind turbine.
  • a rotor rotatable about a substantially horizontal axis and having rotor blades arranged thereon can be set in rotation by wind.
  • the rotor is firmly connected to a rotor shaft - possibly via a gear - with a generator for converting the rotational energy of the rotor into electrical energy.
  • the power-transmitting rotating components from the rotor to the generator are collectively referred to as a drive train and are arranged in a gondola rotatably mounted on a tower.
  • the drive train is mounted at several points, wherein usually at least one bearing is arranged in the region of the rotor shaft. In a so-called. Three-point bearing further storage of the driveline takes place directly over the transmission, d. H.
  • the rotor shaft itself does not have any further bearing, but is mounted indirectly via the integrated mounting only there due to the fixed connection to a transmission or even with a slow-running large generator.
  • EP 1 251 268 A2 and EP 2 620 636 A1 propose rings which are fastened to the rotor shaft and have a multiplicity of outboard bores into which a bolt can optionally engage for locking.
  • the invention relates to a wind energy plant comprising a rotor rotatable about a rotor axis and having a plurality of rotor blades and a rotor connected thereto
  • the invention is based on the finding that a simultaneous engagement of at least three locking bolts in the locking ring of a rotor shaft of a wind energy plant not only ensures locking of the rotor against unwanted rotational movement, but also sufficient support of the rotor shaft. Because of this support, a drive train element attached to the rotor shaft, such as a gearbox or the generator, can also be released from the rotor shaft, even if the rotor shaft is supported indirectly via the drive train element in question. Since, according to the invention, the locking ring is fixedly connected to the rotor shaft and the locking pins are part of the machine carrier, additional components are not required for locking the rotor or for supporting the rotor shaft in the wind energy installation according to the invention.
  • the number of locking openings corresponds to the number of locking bolts
  • their respective arrangement is to be coordinated with one another such that, at least in one rotational position of the rotor shaft, each locking bolt can engage in one locking opening in each case.
  • locking openings and locking pins are distributed uniformly over the circumference, a locking in a number of rotational positions of the rotor shaft corresponding to the number of locking openings or locking bolts is possible.
  • the number of locking recesses is greater than the number of locking bolts. If the locking recesses are suitably arranged, the rotor shaft and thus the rotor can be locked in a number of rotational positions exceeding the number of locking pins.
  • the locking recesses are distributed uniformly over the circumference of the locking ring, so the angular distance between each two adjacent locking recesses is thus constant.
  • the rotor shaft or the rotor can be locked in a number of rotational positions corresponding to the number of locking recesses.
  • the angular distance between two adjacent locking bolts corresponds to the angular spacing of two adjacent locking recesses or a multiple thereof, it is ensured that when a locking bolt engages in a locking recess, any other locking bolt can likewise engage in a locking depression.
  • the individual locking bolts can often be made smaller, which can simplify the integration of the locking bolts into the machine carrier. It is further preferred if at least part of the locking bolts are combined in locking bolt groups, within which the angular distance between two adjacent locking bolts corresponds to the angular distance between two adjacent locking recesses. Particularly advantageous have three Arretianssbolzen philosophy proven each with identical number of locking pin.
  • the locking bolts and / or locking bolt groups may be arranged symmetrically with respect to a vertical plane through the axis of the rotor shaft.
  • the locking bolts and / or locking bolt groups can also be distributed uniformly over the circumference around the rotor shaft.
  • the locking ring can be a separate component fixedly connected to the rotor shaft, it is preferred if the locking ring is integrated directly into the rotor shaft, that is to say is formed integrally with the rotor shaft.
  • the arresting ring be integrated in a provided at the end remote from the rotor mounting flange of the rotor shaft.
  • the mounting flange usually has a radial bore pattern of axial through-holes for attachment of another drive train element, such as, for example, a transmission, or for direct attachment of the generator. It is preferred if the locking recesses are each arranged centrally between two adjacent axial through-holes of the mounting flange.
  • the locking bolts can be hydraulically displaceable.
  • the locking bolts may, for example, be connected to a piston arranged in a cylinder or be made in one piece therewith.
  • the locking bolts have a bore with an internal thread for engagement of a securing bolt and the locking recesses radial through-holes to the interior of the rotor shaft for the passage of securing bolts at its radial end face.
  • suitable securing bolts can be inserted through the radial through holes and screwed into the locking pins. This can be safely avoided accidental retraction of the locking pin, which would lead to a repeal of the rotor lock or the support of the rotor shaft.
  • the locking pins are each surrounded by a compensating bushing and / or in each of the locking recesses a compensating bushing is provided to compensate for manufacturing tolerances and to ensure a uniform introduction of force into all the locking bolts.
  • the compensating bushes are designed so deformable that on the one hand manufacturing tolerances can be compensated, on the other hand sufficient resistance can be made during loading during locking and / or support, in order to transmit the forces occurring.
  • the compensating bushings can be made of plastic. It is also possible for the compensation bushing to be designed as a coating applied directly to the locking bolt and / or in the locking recesses.

  • the transmission 3 is fastened to the machine carrier 7 via a gearbox 8. Due to the connection with the planet carrier 4, the rotor shaft 2 is mounted indirectly via its bearing 9 opposite the machine carrier 7 at this end.
  • a so-called three-point mounting is realized in which the transmission 3 can not be easily detached from the rotor shaft 2 due to the indirect mounting of the rotor shaft 2. Rather, to release the transmission 3, a prior support of the rotor shaft 2 is required.
