Claim 5:
6. A nacelle for a wind turbine, the nacelle comprising:
a nacelle housing;
a rotor hub;
a rotor bearing for bearing the rotor hub on the nacelle housing, wherein the rotor bearing has at least one inner ring element and at least one outer ring element, wherein at least one sliding bearing element is formed between the inner ring element and the outer ring element;
wherein the sliding bearing element comprises multiple individual sliding bearing pads, which are arranged so as to be distributed across the circumference, and wherein the sliding bearing pads are each arranged, by means of at least one fastening means, to that ring element, which is designed to be rotatable relative to the nacelle housing;
wherein the nacelle is configured so that in the course of the changing operation, all of the individual sliding bearing pads are changed, wherein for changing the individual sliding bearing pads, in each case, a sliding bearing pad to be changed is moved into a sliding bearing pad changing position, in which it is not loaded, and
wherein both the inner ring element and the outer ring element are designed to be V-shaped, and a first sliding bearing element and a second sliding bearing element, each having multiple individual sliding bearing pads, are arranged between the two ring elements so as to be axially spaced apart from each other, wherein the two sliding bearing elements are arranged at an angle to one another when viewed in the cross-section, wherein due to a tilting torque acting on the rotor hub, one of the two sliding bearing elements is not loaded at its topmost position and the second of the two sliding bearing elements is not loaded at its bottommost position, which results in the sliding bearing pad changing positions.
