Abstract
Mounting arrangement of the blades on the hub (5) of a wind power turbine comprising a bearing (11) between each blade root (13) and the corresponding hub connection (15) having an inner ring (25) and an outer ring (23) with a stiffening plate (33) attached at least on a part of the outer ring (23), preferably in a perpendicular plane to the blade axis, on the opposed side (29) to the side (37) joined to the hub connection (15).

A mounting arrangement of blades on a hub (5) of a wind power turbine comprising a bearing (11) between each blade root (13) and a corresponding hub connection (15) having an outer ring (23) and an inner ring (25), wherein said inner ring (25) has reinforcing plates (30, 31) of thickness T2 and T3 for minimizing its deflection, and said arrangement further comprises a stiffening plate (33) of thickness T1 attached at least on a part of the outer ring (23) on a side (29) opposed to a side (37) joined to the hub connection (15) so that the stiffness of the upper and lower surfaces of the bearing (11) is equalized.
