摘要： A wind power plant having a sliding bearing with a first and second bearing component which are arranged to rotate relative to one another about a common rotational axis is provided. The sliding bearing has at least one sliding lining arranged between the first and second bearing component and has a contact face with a lubricant. The contact face has a sliding lining duct opening to a sliding lining duct, wherein the sliding lining duct crosses the sliding lining and feeds lubricant into a region between the first and second bearing component. The sliding lining has a groove on the contact face, surrounding the sliding lining duct opening. An operation of the wind power plant to generate electric current is also provided. The sliding bearing operates hydrostatically during a startup phase of the rotational movement and/or operates hydrodynamically during a phase of the rotational movement with a constant rotational speed.

摘要： An arrangement to control the clearance of a sliding bearing is disclosed. A sliding bearing arrangement, of a direct driven wind turbine, comprises a bearing. The bearing comprises a first bearing shell and a second bearing shell, whereby the first bearing shell and the second bearing shell are arranged rotatable in respect to each other. A certain predetermined clearance is present between the first bearing shell and the second bearing shell, while the bearing is in rotation. A first circuit comprises a first fluid, while the first circuit is in thermal contact with the first bearing shell. A second circuit comprises a second fluid, while the second circuit is in thermal contact with the second bearing shell. The first circuit and the second circuit are coupled in a way that a difference in the temperature between the first bearing shell and the second bearing shell is compensated via the first and the second fluid, thus the clearance is kept within a predetermined range.
