Title
(EN) METHOD FOR INSTALLING AND RETAINING A BUSHING IN A BEARING BLOCK OF A ROTOR BLADE JOINT
(FR) PROCÉDÉ D'INSTALLATION ET DE RETENUE D'UNE BAGUE DANS UN BLOC DE PALIER D'UN JOINT DE PALE DE ROTOR
Abstract
(EN)
A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface. The rotor blade also includes one or more pin joints for connecting the first and second blade segments at the chord-wise joint. The pin joint(s) includes one or more pin joint tubes received within the pin joint slot(s). The pin joint slot(s) are secured within a bearing block. Further, a gap is defined between the pin joint slot(s) and the bearing block. Moreover, the rotor blade includes a shim within the gap between the pin joint slot(s) and the bearing block so as to retain the pin joint slot(s) within the bearing block. In addition, the shim is constructed of a liquid material that hardens after being poured into the gap.
(FR)
L'invention concerne une pale de rotor pour une éolienne comprenant un premier segment de pale et un second segment de pale s'étendant dans des directions opposées d'un joint par corde. Chacun des premier et second segments de pale comprend au moins un élément coque définissant une surface portante. La pale de rotor comprend également une ou plusieurs joints mâle et femelle pour relier les premier et second segments de pale au niveau du joint par corde. Le joint(s) mâle et femelle comprend un ou plusieurs tubes de joint mâle et femelle reçus à l'intérieur de la fente de joint(s) mâle et femelle. La fente(s) de joint mâle et femelle est fixée à l'intérieur d'un bloc de support. En outre, un espace est défini entre la fente(s) de joint mâle et femelle et le bloc de support. De plus, la pale de rotor comprend une cale à l'intérieur de l'espace entre la fente(s) de joint mâle et femelle et le bloc de support de manière à retenir la fente(s) de joint mâle et femelle à l'intérieur du bloc de support. De plus, la cale est constituée d'un matériau liquide qui durcit après avoir été versé dans l'espace.
