摘要： A nacelle for a wind turbine includes: a nacelle housing; a rotor shaft; a rotor hub, arranged on the rotor shaft; a first rotor shaft bearing for bearing the rotor shaft on the nacelle housing; and a second rotor shaft bearing. The first rotor shaft bearing and the second rotor shaft bearing are arranged at an axial distance to one another and the first rotor shaft bearing is arranged closer to the rotor hub than the second rotor shaft bearing. The first rotor shaft bearing has a first sliding surface having an averaged first sliding surface diameter and the second rotor shaft bearing has a second sliding surface having an averaged second sliding surface diameter. The first sliding surface faces away from the rotor hub at least in some sections, wherein the first sliding surface and the second sliding surface face one another at least in a partial section.

摘要： A bearing element has at least one inner ring element and at least one outer ring element, wherein, between the inner ring element and the outer ring element, a sliding bearing system is disposed that is formed by at least two sliding bearings. The sliding bearings have a sliding face, which cooperates with a running face of the opposite ring element. In the new condition of the sliding bearing, the sliding face of the sliding bearing, viewed in cross section, has at least one first sub-portion and one second sub-portion, wherein a tangent constructed on the first sub-portion is disposed at a first angle relative to the central longitudinal axis and a tangent constructed on the second sub-portion is disposed at a second angle relative to the central longitudinal axis, wherein the first angle has a magnitude different from that of the second angle.
