The mounting of an adjustable rotor blade on the rotor hub of a wind power installation has as an adjusting drive pivot bearing, a rolling bearing for the transmission of high axial forces and great flexural moments in the event of slight relative movements between the co-operating bearing components. It comprises a bearing race for the one co-operating bearing component, which receives in positively locking relationship two radially mutually displaced rows of rolling bodies, and a bearing race for the other co-operating bearing component, which embraces them in a U-shape in cross-section. The bearing race for the rotor blade forming the other co-operating bearing component comprises two races (10, 12) of different diameters, which are fixed independently of each other to the rotor blade (3). The circular root of the hollow rotor blade (3) is forked to form two shell portions (3a, 3b) and each shell portion is fixed to one of the two races (10, 12) of the one bearing race. |
