Claim 7:
8. A method for changing a sliding bearing element of a rotor bearing of a wind turbine, the method comprising:
providing the rotor bearing, wherein the rotor bearing comprises an inner ring element and an outer ring element, between which the sliding bearing element is arranged, wherein the inner ring element and the outer ring element are rotatable relative to each other, wherein a rotor hub is fastened to the inner ring element or to the outer ring element, wherein the sliding bearing element comprises multiple individual sliding bearing pads, each of which are releasably fastened to the inner ring element or outer ring element of the rotor bearing by means of at least one fastening means;
removing, during the changing of the sliding bearing element, the individual sliding bearing pads one after the other and replacing the individual sliding bearing pads by new sliding bearing pads without disassembling, during the changing of the individual sliding bearing pads of the sliding bearing element, the inner ring element and the outer ring element,
wherein the method comprises the following method steps:
rotating the rotor hub relative to a nacelle housing of the nacelle until one of the sliding bearing pads arrives at a sliding bearing pad changing position, which is a topmost position or a bottommost position, at which it is not loaded;
removing that sliding bearing pad which is situated at the sliding bearing pad changing position and inserting a new sliding bearing pad in place of the removed sliding bearing pad;
rotating the rotor hub relative to the nacelle housing of the nacelle until a further one of the sliding bearing pads arrives at the sliding bearing pad changing position;
removing that sliding bearing pad which is situated at the sliding bearing pad changing position and inserting a new sliding bearing pad in place of the removed sliding bearing pad;
performing the above method steps until all of the old sliding bearing pads are replaced by new sliding bearing pads.
