Abstract

L'invention concerne un palier pour une éolienne. Le palier comprend une bague de roulement externe, une bague de roulement interne et une bague de roulement centrale fendu radialement configuré entre la bague de roulement interne et la bague de roulement externe. En outre, la bague centrale comprend une première partie de bague et une seconde partie de bague séparée. De plus, les première et seconde parties de bague de roulement sont agencées ensemble dans une direction axiale. Le palier comprend également un premier ensemble d'éléments de roulement positionnés entre la bague de roulement interne et la bague de roulement centrale et un second ensemble d'éléments de roulement positionnés entre la bague de roulement centrale et la bague de roulement externe.
