Title
(EN) A WIND TURBINE NACELLE STRUCTURE AND A METHOD OF ASSEMBLING A WIND TURBINE NACELLE STRUCTURE
(FR) STRUCTURE DE NACELLE D'ÉOLIENNE ET SON PROCÉDÉ D'ASSEMBLAGE
Abstract
(EN)
A nacelle of a wind turbine generator comprising: a base frame (10) that is separate from and which supports a main bearing housing (12), in use, the base frame (10) being configured to connect with a lower portion of the main bearing housing (12); and a nacelle structure (8) that is separate from and which is connected to the base frame (10) at a first connection, wherein that nacelle structure (8) extends away from the base frame (10) and defines at least in part an interior nacelle volume; characterised in that the nacelle structure (8) is connected to the main bearing housing (12) by way of a second connection at a point arranged above a plane of a rotor axis of the main bearing housing (12).
(FR)
L'invention concerne une nacelle d'un générateur éolien, comprenant : un cadre de base (10) qui est séparé d'un logement de palier principal (12) et qui le supporte, lors de l'utilisation, le cadre de base (10) étant configuré pour être relié à une partie inférieure du logement de palier principal (12); et une structure de nacelle (8) qui est séparée du cadre de base (10) et qui est reliée à celui-ci au niveau d'une première liaison, la structure de nacelle (8) s'étendant à l'opposé du cadre de base (10) et définissant au moins en partie un volume intérieur de nacelle. La présente invention est caractérisée en ce que la structure de nacelle (8) soit reliée au logement de palier principal (12) par l'intermédiaire d'une deuxième liaison au niveau d'un point situé au-dessus d'un plan d'un axe de rotor du logement de palier principal (12).
