Problems solved by technology

Compared with other faults of wind power plants, a completely different situation arises with regard to costs, in that faults in the bearing structure of the rotor shaft result in significantly higher costs than other common faults of wind power plants and stop time
Despite the reinforcement technology "rolling bearings", especially bearing failures in the multi-megawatt range significantly reduce the economics of wind power plants due to high maintenance and repair costs or due to long standstill times
Especially in so-called off-shore applications, this presents problems linked to higher costs due to the inaccessibility of the equipment
The reason for this high failure cost or long failure time is that in the case of a bearing failure when rolling bearings are used, the entire rotor generally has to be dismantled

Embodiment Construction

[0042] It should first be understood that the disclosure contained in the entire description can be used without reference to the same parts or the same component reference numerals. Positional designations selected in the description, such as "upper", "lower", "sideward", etc., relate to the directly described and illustrated figure and can be used meaningfully to the new position in the event of a position change. Furthermore, individual features or combinations of features of the various exemplary embodiments shown and described can also themselves be independent solutions according to the invention.

[0043] figure 1 A detail of a wind power plant 1 , as is known in principle from the prior art, is shown in oblique view and partially in section. The wind power plant 1 comprises a tower 2 at the tip of which a pod 3 is arranged. Arranged in this nacelle 3 is a rotor hub 4 which carries rotor blades 5 at one end thereof, in particular in a rotationally movable manner. To ...

Abstract

The invention relates to a bearing element (7) for supporting the rotor hub (4) of a wind turbine (1), comprising at least one inner ring element (10, 40) and at least one outer ring element (11, 41), wherein a plain bearing is formed between the inner ring element (10, 40) and the outer ring element (11, 41), and wherein the plain bearing is formed by at least two plain bearings (8, 9, 38, 39) arranged at an axial distance (44) from one other.

Description

technical field [0001] The invention relates to a bearing element for supporting a rotor hub of a wind power plant, said bearing element having at least one inner ring element and at least one outer ring element, wherein between said inner ring element and said outer ring element A sliding bearing structure is formed between them, and the invention relates to a wind power plant with a rotor having a rotor hub which is supported on a stator, wherein between the rotor and the stator a support element. Background technique [0002] Although sliding bearings have a significantly higher service life than rolling bearings, rolling bearings are still predominantly used today in wind power plants, in particular as main bearings for supporting the rotor. Various studies of wind power plants have shown that, in addition to other different causes of failure throughout the area of ​​the generator or the rotor blades themselves or the rotor, the "bearing" cause of failure has a very hig...
