Abstract

A bearing assembly of a rotor of a wind turbine, for mounting a shaft of the rotor in a fixed housing, wherein the shaft of the rotor is coupled to rotor blades of the rotor via a hub, includes: a plurality of first housing-side axial slide bearing segments engaging on the housing; a plurality of second housing-side axial slide bearing segments; a plurality of first housing-side radial slide bearing segments; and a plurality of second housing-side radial slide bearing segments. An axial distance between the first and second axial sliding surfaces of the rotor defines a bearing length l. The radial sliding surfaces of the rotor on which the first and second radial slide bearing segments are supported, define a bearing diameter d of the bearing assembly, and V≤1 applies to a ratio V=l/d between the bearing length l and the bearing diameter d.
