Abstract

The invention relates to a bearing arrangement for a wind turbine comprising a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing, the bearing arrangement further comprising a downwind bearing and an upwind bearing as radial fluid bearings, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft, whereby the bearing housing is formed from at least two separate bearing housing pieces, whereby the at least two separate bearing housing pieces are joined with each other and / or the drive shaft is formed from at least two separate drive shaft pieces, whereby the at least two separate drive shaft pieces are joined with eachother. The invention further relates to a wind turbine comprising a bearing arrangement, whereby the wind turbine further comprises a rotor operatively connected to drive the drive shaft and a generator operatively connected to be driven by the drive shaft.

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 EP3276192A1. [0003] The rotating drive shafts in large wind turbines are long and have large diameters with very tight tolerances on the bearing raceways. Casting and machining of such shafts is very difficult and expensive. However, a single bearing housing is required to maintain the cleanliness of the lubrication at an acceptable level. The diameter of such a bea...
