Abstract
(EN) A bearing assembly for a wind turbine, the bearing assembly comprising an inner race and an outer race; wherein at least one of the inner race or the outer race comprises a plurality of interconnected struts, the struts being interconnected by node members to form a lattice structure.
(FR) L'invention concerne un ensemble palier pour une éolienne, l'ensemble palier comprenant un chemin de roulement interne et un chemin de roulement externe; au moins l'un parmi le chemin de roulement interne ou le chemin de roulement externe comprenant une pluralité d'entretoises interconnectées, les entretoises étant interconnectées par des éléments de nœud pour former une structure en treillis.
