TURNING RING BEARING STRUCTURE FOR WIND TURBINE, AND METHOD FOR REPLACING TURNING RING BEARING STRUCTURE FOR WIND TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a turning ring bearing structure for a wind turbine and a method for replacing the turning ring bearing structure for the wind turbine, by which the bearing can be replaced without removing a blade from a rotor head of the wind turbine.

SOLUTION: The turning ring bearing structure for the wind turbine includes: an outer ring 2 which is bolt-connected to the rotor head; an inner ring 3 which is bolt-conncted to the wind turbine blades; and a plurality of balls 4 which are arranged in one or more rows in the circumferential direction between the outer ring 2 and the inner ring 3. At least one of the outer ring 2 and the inner ring 3 comprises a plurality of divided members 2A, 3A. Two adjacent divided members 2A, 3A are provided to be separated from each other.
