Roller-bearing arrangement and a wind turbine

Abstract

The invention relates to a roller-bearing arrangement, particularly a large-diameter roller-bearing arrangement for a wind turbine, comprising an outer ring and an inner ring that can be rotated about a rotational axis, relative to said outer ring, said roller-bearing arrangement comprising a first raceway in which a plurality of first roller elements are arranged and which is designed between a first ring extension of the outer ring and a second ring extension of the inner ring, said second ring extension engaging behind the first ring extension in a radial direction relative to the rotational axis.

Description

technical field

[0001] The invention relates to a roller bearing arrangement according to the preamble of claim 1 . Background technique

[0002] Such roller bearing arrangements are well known in the prior art and are used, for example, in the form of so-called large roller bearings for mounting rotor shafts of wind power stations. A wind power station usually comprises a tower and a gondola which is rotatably arranged on the tower and acts as a support for the machine. One end of the rotor shaft arranged in the gondola is connected to the rotor hub with the rotor blades driven by the wind, while the other end is directly or indirectly coupled via a possible transmission to a generator for generating electricity.

[0003] The problem with said wind power plants is that, especially in the case of varying wind loads, extremely high axial forces along the rotor shaft and substantially oblique forces perpendicular to the rotor shaft occur in the region of the rotor shaft, requ...
