More Information
Summary:A wind turbine rotor shaft arrangement, e.g. of horizontal type, comprising a rotor shaft for supporting wind turbine blades, a non-rotating first housing structure for supporting the rotor shaft, and a first rolling bearing arranged to support, in a first axial direction, the rotor shaft in relation to the first housing structure at a first support point. The first rolling bearing is a single row self-aligning bearing comprising an inner ring, an outer ring, and a set of rolling elements formed of rollers arranged in an intermediate configuration between the inner and outer rings. Each roller is a symmetrical bearing roller having a curved raceway-contacting surface arranged contacting a curved inner raceway of the inner ring and a curved outer raceway of the outer ring. A contact angle between each roller and the inner and/or outer raceway is inclined in relation to the radial direction of the rotor shaft.
