Abstract

De nos jours, le transport de nacelles dans des conteneurs standard n'est possible que jusqu'à une certaine taille. En particulier, pour les installations de plus de 1,25 MW, les dimensions de nacelle sont telles que la nacelle ne peut plus être transportée au moyen de conteneurs standard. L'invention prévoit une chaîne cinématique pour éolienne, avec laquelle il est possible de transporter des éoliennes de plus de 1,25 MW au moyen de conteneurs standard. A cet effet, la chaîne cinématique pour éolienne selon l'invention comporte un entraînement planétaire et un générateur fixés par flasque l'un contre l'autre, ledit générateur comportant un premier rotor, dans et/ou sur lequel est disposé un premier aimant, et un premier stator présentant un enroulement conducteur, ledit générateur comportant au moins un deuxième rotor dans et/ou sur lequel est disposé un deuxième aimant.
