The invention relates to a rolling bearing arrangement comprising two concentric rings, at least sections of which are arranged inside one another and comprising a gap between said rings, allowing the latter to rotate in opposition to one another about an imaginary axis in the centre of the rings that runs approximately perpendicularly to the ring plane. A race for at least one row of rotationally symmetrical rolling bodies that roll between the rings is situated in the vicinity of a gap section between the rings that surrounds the rotational axis at a constant radius, said race forming a closed loop on one plane. The rolling bodies in one row are guided through a cage at approximately equidistant intervals, said cage having at least one disc-shaped region set into a continuous circular groove-type depression in the vicinity of the race of a bearing ring and a comb-type form with a plurality of spacer pieces that are interconnected in combination along a back region, each piece having a pocket formed between neighbouring spacer pieces for receiving a respective rolling body, the opening of each pocket extending continuously in the upper face of the cage beyond the edge of said cage lying opposite the back region into the lower face. According to the invention, the cage is completely interrupted in at least one place and formed from a resilient material, so that it can be bent up and/or together in the region of the approximately disc-shaped region. The invention further relates to a wind turbine equipped with said bearing arrangement.
The invention is directed towards a machine tool for incorporating gear teeth into the inner side of an annular work piece by metal-cutting, with a) an annular machining table for the support or placing on of at least one workpiece, and b) a chassis for holding, supporting, mounting and/or guiding a tool head, which chassis extends, at least during the machining, through the annular machining table or through a central opening in the annular machining table from a bed or pedestal below said machining table.
The invention relates to a wind power plant of greater power, wherein the rotor blades are adjusted in order to minimize the static and/or dynamic structural load, and/or in order to attenuate vibrations, such as due to the generation of counter-forces to forces and torques inhibiting compensation, even if a constant wind speed v∞ does not require so, and to a method for operating such a wind power plant; for this purpose the invention provides to configure at least one rotor blade bearing as a rolling bearing, which is optimized for a high amount of overturns in that the entire dynamic axial load rating Ca,ges determined, according to DIN ISO 281, of all rows (μ) of a rolling bearing employed according to DIN ISO 281 and involved in the transmission of power in an axial direction corresponds to at least 1.5 times of the dynamic axial load rating Ca,ref according to DIN ISO 281 of a two-row rotary joint having comparable dimensions with regard to the surface of the bearing cross-section and the circumference at the center of gravity of the surface, and having identical spheres in both rows, and having an angle of support α of 45°; and/or in that the nominal service life L10 of a ball bearing employed, determined according to DIN ISO 281, corresponds to at least 3.375 times the service life L10,ref of a two-row rotary joint, calculated according to DIN ISO 281, having comparable dimensions with regard to the surface of the bearing cross-section and the circumference at the center of gravity of the surface, and having identical spheres in both rows, and having an angle of support α of 45°.

Bearing unit for a long rotor blade of a wind power installation, wind power installation comprising one such rotor blade bearing arrangement, and method for operating one such wind power installation
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. To this end, two running tracks are arranged between the two connection elements, are axially staggered in relation to each other, and comprise rolling bodies with an approximately cylindrical shape, said rolling bodies being oriented in such a way that the rotational axes thereof intersect the longitudinal axis of the rotor blade in question at an angle of between 30° and 90°. The invention also rates to a wind power installation provided with one such rotor blade bearing arrangement, and to a method for operating one such wind power installation. The at least one rotor blade in question is continuously rotted about the longitudinal axis thereof during the option of the wind power installation.
The invention is aimed at a rolling bearing arrangement (1;1',1') having two annular elements (2,3), which are arranged concentrically with respect to one another and at least in regions one inside the other, for connecting to in each case one of two system parts which are rotatable relative to one another, and having a gap (11) between said connecting elements (2,3), such that said connecting elements (2,3) are rotatable relative to one another about an imaginary axis, which is approximately perpendicular to the ring plane, in the center of the annular connecting elements, wherein at least two rows of rolling bodies (21, 22, 24, 24') are provided in the region of the gap between the connecting elements, wherein the annular connecting elements completely or partially overlap one another in the radial direction, and one or more raceways (19,20,25,26) for rolling bodies are arranged in radially overlapping regions (10,16) of the annular connecting elements, in such a way that the support angle which the connecting line between the centers of the contact points of a rolling body (21,22) with its two raceways encloses with respect to the annular plane is equal to or greater than 75˚, and wherein the rolling bodies (24,24') of at least one row have a support angle of 15˚ or less.
