Definitions

  • the object of the present invention is to describe a yaw crown with a sliding base, of those used in wind turbines.
  • the present invention describes a yaw crown essentially composed of a toothed crown that rests on steel plates (upper and lower) and an intermediate plate, treated to prevent corrosion of these systems.
  • Wind turbines consist of a fixed tower that raises an electric generator connected to a rotor by mechanical means on the ground.
  • the rotor is formed by a hub or hub that joins one or more blades that are responsible for transforming the kinetic energy of the wind into rotational movement of the rotor.
  • the generator is placed on a frame, which is capable of having movement with respect to the tower that supports it, so that it allows the rotor to face the wind.
  • An orientation mode can be freeing the rotation of the frame (which is part of what is usually called the wind turbine gondola, oriented to leeward) that would act as a weather vane.
  • a mechanical system is usually used to move the frame with the rotor to a desired orientation (windward orientation).
  • windmill yaw crowns are composed of a single piece, which withstands great stresses that can damage it. These damages involve repairs that are going to be less complex, such as those described in the PCT with publication number WO2004 / 001223.
  • Wind turbine maintenance is greatly simplified given its modular concept.
  • the winking crown is essentially formed by a toothed crown that rests on a set formed by:
  • a fixed plate (preferably lower) of stainless steel with at least 2 millimeters thick.
  • a yaw base used as a friction plate between the fixed plates.
  • the yaw base has two entrusted uses: first, it works as a sliding base when the wind turbine is in full yaw movement; secondly, it acts as a brake disc when the wind turbine is held.
  • the characteristics that this sliding yaw base must have are, essentially, a low manufacturing cost, have a smooth surface and be resistant to corrosion. That is why its construction has been specified in a commonly used steel such as S355 and no expensive and technologically superior treatments, such as those based on tungsten, have been used. On the other hand, and due to the same manufacturing requirements, the use of grease and normal paint has been discarded.
  • the sliding base is between two fixed stainless steel plates.
  • the bearings located between both mentioned plates facilitate the movement of the wind turbine during the yaw.
  • the yaw base is treated with a layer of zinc that, at the same time, acts as a layer of adaptation of electrical potentials between the different steels, also managing to solve the problems of corrosion and wear due to the difference of potential between different materials.
  • the upper and lower plates are mechanically attached to the yaw base.
  • the lower plate is mechanically joined, by its external diameter and between them, to the upper flange of the tower and to the yaw base; in its internal diameter it is attached to the radial bearings and to the yaw base.
  • the top plate is located between the yaw base and the toothed crown. Like the lower plate, it is fixed in position between the yaw base and the upper edge of the tower, an integral part of the generator.
  • the upper and lower plates are fixed in their radial and tangential directions due to friction between their elements.
  • the zinc plate used as anti-corrosion treatment significantly increases the friction between the yaw base and the fixed elements, likewise, this friction is greater than the friction between the yaw base and the bearings, so there is no movement between the base and the plates, since the movement occurs in the bearings.
  • the upper and lower plates are divided into segments every 45 °, with a total of 8 segments in each upper and lower plate. Through this we managed to reduce the overall cost and easier maintenance and assembly, as well as greater ease of transport.
  • FIG. 1 shows a partial and perspective view of the sliding base yaw crown object of the present invention patent. Also, in detail (a) the main constituent elements of the present invention are appreciated.
  • the winding crown with a sliding base in wind turbines object of the present invention patent, is constituted by the following elements: - A bottom plate (1), essentially circular, divided into segments of 45 °, adjacent narrows, up to a total of 8 for a 360 ° plate, provided with a few second guide holes (11).
  • (7 and 8) are preferably linear ridamientos.
  • a toothed crown (5) provided with first guide holes (51), also being fixed by their corresponding bolts.
  • the appropriate position will be decided by the coincidence of the position of the guide holes (11, 21, 31 and 51), and the insertion of the corresponding director bushings, one per hole.
  • the lower plate (1) is fixed between the upper flanges of the tower (6) and the yaw base (2).
  • the upper plate (3) is fixed between the yaw base (2) and the crown gear (5).
  • the lower fixed plate (1) is such that the friction between the lower fixed plate (1) and the yaw base (2) is greater than the friction between the lower fixed plate (l) and the linear bearings (8).
  • the upper fixed plate (3) is such that the friction between the upper fixed plate (3) and the yaw base (2) is greater than the friction between the upper fixed plate (3) and the linear bearings (7).
  • the radial bearing (4) is fixed to the yaw base (2) with a radial bolt (10) and / or adhesive.

Abstract

L'invention concerne une couronne à lacet à base coulissante pour aérogénérateurs et son procédé d'assemblage, composée principalement d'une plaque inférieure (1), d'une plaque supérieure (3) et d'une base à lacet (2), disposant d'une pellicule de zinc pour éviter le problème lié à la corrosion galvanique. L'ensemble tourne sur son axe grâce à des roulements radiaux (4) fixés entre la plaque supérieure (3) et la plaque inférieure (1), le frottement entre les plaques (1) et (3) et la base à lacet (2) étant supérieur au frottement entre les roulements radiaux (4) et la base à lacet (2).
