Abstract:
La présente invention porte sur un procédé pour l'ajustage d'un contour prédéterminé d'un pied d'aube de turbine(4) comprenant une arête saillante principale définie par un angle intérieur déterminé. Selon l'invention, on effectue les étapes successives suivantes: A/on chanfreine l'arête principale du contour, de manière à obtenir deux arêtes saillantes auxiliaires dont les angles intérieurs associés sont respectivement supérieurs à l'angle intérieur de l'arête principale; et B/on émousse les arêtes auxiliaires obtenues, pour parfaire l'ajustage du contour du pied d'aube(4).

Erfindungsgemäß wird zur Bearbeitung von robotergeführten Bauteilen, insbesondere Turbinenschaufeln (1), mit einem Werkzeug (2), welches gelenkig (3, 23, 34) an einem Werkzeughalter (4) befestigt ist, eine Auslenkung (α, ß) des Werkzeugs (2) gegenüber dem Werkzeughalter (4) aus einer Soll-Position (2') erfasst und eine Pose eines ein Bauteil führenden Roboters (IR) auf Basis dieser Auslenkung geändert.
Abstract:
An apparatus (60) is provided for forming a trailing edge (52) of a wind turbine blade having first and second shells (40, 42). The first and second shells define a gap therebetween, and the apparatus has a first mold component (62) that is adapted to form the first or second shell, and an engaging element (77). The engaging element is configured to securely support a trailing edge component to be coupled to the first and second shells. The engaging element is coupled to the first mold component. The apparatus may additionally include a second mold component (64) that is adapted to form the other of the first or second shells and which is coupled to the first mold component. In this embodiment, the first and second mold components have a closed position in which the first and second shells are closed over one another so as to define a generally closed profile of the wind turbine blade.
Abstract:
A handling system (11) for a wind turbine nacelle (3) in connection with self-loading or self -unloading of the nacelle (3) to or from a vehicle. The system (11) comprises two or more lifting means (15, 16) for displacing the nacelle (3) substantially vertically during the self-loading or self -unloading of the nacelle (3). The lifting means (15, 16) further comprises displacing means (28) for displacing the lifting means (15, 16) or apart of the lifting means (15, 16). Furthermore a method for transport of a wind turbine nacelle (3), a method for vertical displacement of a wind turbine nacelle (3) and use of a handling system (11) are disclosed.
Abstract:
A handling system (11) for a wind turbine nacelle (3) in connection with self-loading or self -unloading of the nacelle (3) to or from a vehicle. The system comprises to or more lifting means (15), where the lifting means (15) are engaged with lifting areas (14) of a load carrying structure (10) of the nacelle (3). The lifting areas (14) are a part of the load carrying structure (10) or are integrated in the load carrying structure (10), and where the lifting means (15) lifts by applying linear force to the load carrying structure (10) of the nacelle (3). Furthermore a method for vertical displacement of a wind turbine nacelle (3) and a wind turbine nacelle (3) prepared for self-loading or self-unloading to or from a vehicle are disclosed.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung (10) zum Verbinden von mindestens einem Schaufelblatt (12) oder von mindestens einem Teil eines Schaufelblatts (12) mit einem Rotorträger (14) einer Gasturbine, insbesondere einem Schaufelblattansatz (16) des Rotorträgers (14), wobei das Verbinden entsprechender Verbindungs flächen (20, 22) des Schaufelblatts (12), des Schaufelblattteils, des Rotorträgers (14) oder des Schaufelblattansatzes (16) des Rotorträgers (14) mittels eines induktiven Hochfrequenzpressschweißens erfolgt. Dabei erfolgt die Zufuhr des mindestens einen Schaufelblatts (12) oder Schaufelblattteils automatisch aus mindestens einem Schaufelblatt- und/oder Schaufelblattteil-Reservoir und zudem erfolgt eine automatische Positionierung des Rotorträgers (14), derart, dass die zu verbindenden Verbindungs flächen (20, 22) für den Verbindungsvorgang exakt zueinander positioniert werden.
Abstract:
The present invention relates to a method of manufacturing a blade for a wind turbine, wherein the blade is made in one or more moulds; and wherein the blade has integrally moulded root bushings in the root of the blade for direct or indirect attachment to a hub in a wind turbine. The novel aspect of the invention is that the root bushings (203) in the root (201) of the blade are levelled by shortening of at least one of the root bushings prior to the blade being removed from a supporting mould (205). The invention further relates to a blade made in accordance with the method and a levelling unit (207) for levelling the root of the blade, wherein the levelling unit comprises means for mounting on a mould.
Abstract:
A fixture assembly (40) for securely positioning a plurality of blades (24) loosely assembled on to a rotor (22) of a gas turbine engine in which axial clamping forces are translated to apply radial expansion forces on the blades (24) to simulate a centrifugal force on the blades (24) during engine operation.
