The bearing has outer and inner bearing rings (131, 151) extending at two different radial distances with respect to an axis (50c) of a blade (5c). A series of roll bearings (11a, 11b) are staged at different levels along a direction parallel to the axis. Two bolts (27, 25) fix the rings on a rotor hub and on the blade, respectively, where the ring (131) is directly fixed on a connection part that is intimately connected to the rotor hub. The outer ring (131) is separated into two parts (131a, 131b) on a surface transversal to the axis of the blade for mounting or dismounting the bearings. An independent claim is also included for a wind mill comprising a bearing interposed between a blade and a rotor hub. |
