1. A bearing assembly (10) of a rotor (11) of a wind turbine, for mounting the rotor (11) in a fixed housing (12), comprising:
a plurality of rotor-side axial slide bearing segments (13), each configured to:
engage on the rotor (11), rotate together with the rotor (11), and
be supported against a sliding surface (14) of the housing (12);
a plurality of housing-side axial slide bearing segments (15), each axially adjacent to a respective one of the rotor-side axial slide bearing segments (13) and configured to:
engage on the housing (12), be fixed together with the housing (12), and
be supported against a first sliding surface (16) of the rotor (11); and
a plurality of housing-side radial slide bearing segments (21), each arranged radially inside the plurality of housing-side axial slide bearing segments (15) and the plurality of rotor-side axial slide bearing segments (13) and configured to:
engage on the housing (12), be fixed together with the housing (12), and
be supported against a second sliding surface (22) of the rotor (11),
wherein the sliding surface (14) of the housing (12) is parallel to the first sliding surface (16) of the rotor (11), and
wherein the second sliding surface (22) of the rotor (11) is perpendicular to the first sliding surface (16) of the rotor (11).
 
4. A bearing assembly of a rotor (11) of a wind turbine, for mounting the rotor (11) in a fixed housing (12), comprising:
a plurality of rotor-side axial slide bearing segments (13), each configured to: engage on the rotor (11), rotate together with the rotor (11), and be supported against a sliding surface (14) of the housing (12);
a plurality of housing-side axial slide bearing segments (15), each configured to: engage on the housing (12), be fixed together with the housing (12), and be supported against a first sliding surface (16) of the rotor (11);
a plurality of housing-side radial slide bearing segments (21), each configured to: engage on the housing (12), be fixed together with the housing (12) and be supported against a second sliding surface (22) of the rotor (11),
a radial projection (17) of the rotor (11) configured as a rotor-side thrust collar secured to a hub or shaft (18) of the rotor (11), wherein the rotor-side axial slide bearing segments (13) are fastened to the radial projection (17); and
axial projections (23) on the radial projection (17) of the rotor (11), the axial projections (23) together with the radial projection (17) defining receiving pockets (24) for the rotor-side axial slide bearing segments (13).
