Wind turbine main bearing

摘要

The invention describes a wind turbine main bearing (1) realized to bear a shaft (13) of a wind turbine (10), which shaft is caused to rotate by a number of blades (11) connected to the shaft (13), characterized in that the wind turbine main bearing (1) comprises a fluid bearing (1) with a plurality of bearing pads (2) arranged about the shaft (13). The invention also describes a wind turbine (10) comprising a number of blades (11) connected to a shaft (13) and realized to rotate the shaft (13), which wind turbine (10) comprises as main bearing (1) a wind turbine main bearing (1). The invention further describes a method of performing maintenance on a wind turbine (10) according to any of claims 12 to 14, comprising the steps of halting a rotation of the shaft (13), operating a lifting arrangement (22) to raise the shaft (13), and removing a bearing pad (2) of the wind turbine main bearing (1) from the bearing housing (3) of the wind turbine main bearing (1).
