  • Patent number: 8545186
    Abstract: A bearing arrangement of a rotor for a wind power plant. The bearing arrangement includes a rotor hub with at least one rotor blade, and a rolling bearing, by which the rotor hub is mounted in a gondola of the wind power plant so as to be rotatable relative to a machine support. The rolling bearing has an external ring and an internal ring, between which rolling elements are arranged. In order to make it easier to mount and dismount the bearing arrangement, the rolling bearing is coaxially disposed in a cylindrical opening of the rotor hub, which is externally open in an axial direction, and the external ring of the rolling bearing is connected to the rotor hub in a rotationally fixed and releasable manner.

  • Patent number: 8523453
    Abstract: An axial radial bearing for a rotor shaft of a wind power installation, which has a vertical circular outer disk, inner ring arranged coaxially to the outer disk, and two circular shaft washers axially arranged on both sides of the outer disk. At least one row of rolling bodies, held at equal distances by a bearing cage, extends between the shaft washers and outer disk, forming the rolling bearings for receiving axial forces, while at least one other row of rolling bodies, optionally held at equal distances by another bearing cage, is arranged between the outer disk and inner ring, forming a third rolling bearing for receiving radial forces. The two rolling bearings for receiving radial forces are formed by two tapered roller bearings oriented towards the longitudinal axis of the bearing by the small front sides, or by a double-row angular ball bearing or by two axial ball bearings.

  • Patent number: 8222759
    Abstract: A rotor bearing for a wind turbine with a machine housing rotatably received on a tower. The housing has a generator, a wind-driven rotor with a rotor hub carrying rotor blades and a large rolling bearing carrying the rotor. The large rolling bearing has a first bearing ring, which is non-rotatably fastened on the housing and arranged coaxially to the rotor hub, and a second hearing ring, which is rotatably held on the first bearing ring and fastened to the rotor hub, and rolling elements rolling between the bearing rings. The large rolling bearing is connected to a planetary gear which is connected to the generator and has a ring gear with a peripheral internal gear, planet gears received on planet carriers and a central sun gear. The radially inner bearing ring is also the ring gear connected to the generator, its interior being configured with the peripheral internal gear.
