Problems solved by technology

Current solutions are cumbersome as they involve separate lubrication of the bearing components of the bearings, complex control systems with multiple high and low pressure lines and multiple pumps
In addition, these components are prone to failure, and due to the large number of components in the bearings, downtime of wind turbines occurs more frequently than desired

Embodiment Construction

[0038] figure 1 A side view of wind turbine 10 is shown. The wind turbine 10 comprises a support tower 20 and a nacelle 30 , wherein the nacelle 30 is attached to the support tower 20 . The nacelle 30 includes a bearing arrangement 70 which, in figure 1 not shown in but in figure 2 As can be seen in the figure, the wind turbine 10 also includes a generator 40 attached to a rotor 50 of the wind turbine 10 . Two wind turbine blades 60.1, 60.2 are attached to the rotor 50.

[0039] figure 2 shows along the figure 1 A side perspective view of a section along the longitudinal axis A of the bearing arrangement 70 of the wind turbine 10 . The bearing device 70 includes a bearing housing 80 and a drive shaft 90, wherein the drive shaft 90 is along the figure 2 The bearing housing 80 is arranged in the axial direction of the longitudinal axis A of the bearing housing 80 shown in . The axial direction along the longitudinal axis A of the bearing housing 80 corresponds to t...

Abstract

The invention relates to a bearing arrangement (70) for a wind turbine (10) comprising a bearing housing (80) and a drive shaft (90), whereby the drive shaft (90) is arranged within the bearing housing (80) in an axial direction along a longitudinal axis (A) of the bearing housing (80), the bearing arrangement (70) further comprising a downwind bearing (100) and an upwind bearing (200) as radial fluid bearings, whereby the downwind bearing (100) and the upwind bearing (200) are arranged between the bearing housing (80) and the drive shaft (90). The downwind bearing (100) and / or the upwind bearing (200) comprises a lubricant flooded chamber (101, 201), in which multiple radial bearing pads (105, 205) are arranged about the drive shaft (90), whereby the lubricant flooded chamber (101, 201) is sealed against the drive shaft (90), an internal space (82) of the bearing housing (80) and an outside of the bearing housing (80).

Description

technical field [0001] The invention relates to a bearing arrangement for a wind turbine and to a wind turbine. Background technique [0002] Typically, a bearing arrangement of a wind turbine comprises a bearing housing and a drive shaft, wherein the drive shaft is arranged within the bearing housing in an axial direction along the longitudinal axis of the bearing housing. The bearings of the bearing arrangement are arranged around the drive shaft such that the drive shaft can rotate within the bearing housing by means of the rotor of the wind turbine. Such a bearing arrangement is known, for example, from EP 3276192 A1. [0003] The bearings of a bearing arrangement require constant lubrication to function properly. Current solutions are cumbersome as they involve separate lubrication of the bearing components of the bearings, complex control systems with multiple high and low pressure lines and multiple pumps. Furthermore, these components are prone to failure, and due...
