Abstract: The invention relates to a rolling bearing arrangement (5) for mounting parts of a wind power plant (1), comprising three relatively rotatable annular elements (6-8) arranged concentrically with one another and at least regionally inside one another for connection to relatively rotatable parts of the wind power plant, wherein two relatively rotatable connecting elements (6-9) are separated from each other by a gap (9, 10) and partially or wholly overlap each other in the radial direction, wherein, further, provided in the region of a gap in radially overlapping regions of the annular connecting elements are at least two rows of rolling elements (34, 35), each of which rolls along a respective two raceways (32, 33) that overlap each other at least regionally in the radial direction, as well as at least one additional row of rolling elements (42) whose raceways do not overlap in the radial direction, wherein the radially innermost connecting element and the radially outermost connecting element are connected to

Abstract: A rotary joint for use in a system for generating energy from water power, the joint comprising a first rotationally symmetrical connecting element and a second rotationally symmetrical connecting element disposed concentrically with the first connecting element and rotatable relative thereto, an annular gap between the two connecting elements, and a row of rolling elements rolling along a race on each of the connecting elements, wherein provided to seal the annular gap is a sealing device having a sealing ring fixed to the first connecting element, and a circumferential sealing lip, or sealing surface, extends along a lead-in surface, wherein the second connecting element is divided into a race ring, with at least one race, and a lead-in ring with a lead-in surface for at least one sealing ring, the lead-in ring being removably connected to at least one race ring.

Abstract: The invention relates to a bearing unit for a long rotor blade, especially a wind power installation, said bearing unit comprising two annular elements that can be rotated in relation to each other and are directly or indirectly connected to the rotor blade hub and to the rotor blade, and at least two running tracks that can be axially staggered in relation to each other and comprise peripheral rolling bodies with an approximately cylindrical shape, i.e. each comprising a lateral surface that is rotationally symmetrical to a rotational axis in a very precise manner. The aim of the invention is to be able to fully absorb the tipping moment caused by the wind pressure on the rotor blade and on the bearing unit, and optionally to absorb other forces and other moments.
