ROTATING RING BEARING STRUCTURE FOR WIND WHEEL AND METHOD FOR REPLACING ROTATING RING BEARING STRUCTURE FOR WIND WHEEL

摘要

A rotating ring bearing structure for a wind wheel is provided with an outer ring (2) which is bolted and joined to a rotor head, an inner ring (3) which is bolted and joined to the wind wheel blades, and balls (4) which are arranged in one or more rows in the circumferential direction between the outer ring (2) and the inner ring (3). Either the outer ring (2) and/or the inner ring (3) comprises divided members (2A, 3A). Two adjacent divided members (2A, 3A) are provided so as to be separated from each other. As a result of the configuration, the bearing can be replaced without removing the blades from the rotor head of the wind wheel.
