A lubrication system for a wind turbine is provided, the lubrication system including a lubricant consumer to which fresh lubricant is supplied and out of which used lubricant is extracted, a pump for pumping fresh lubricant to the lubricant consumer, a waste lubricant collector where used lubricant can flow after being extracted from the lubricant consumer, and a plurality of containers delivering fresh lubricant to the lubrication system.

A seal arrangement is disclosed for sealing an interior space between a bearing housing and a rotatable shaft with respect to a surrounding area. The seal arrangement includes a seal body which can be fastened to the bearing housing with a first end and a second end. The seal body is extended in an elongate manner along a main extent direction and is configured to be arranged in an annular manner around the rotatable shaft in a mounted state. The first end and the second end have a common butt joint. A projecting region is arranged at the first end of the seal body and projects tangentially with respect to the rotatable shaft in the direction of a predefined main rotational direction of the rotatable shaft. The projecting region projects beyond the seal body and overlaps the butt joint.

Methods for installing a wind turbine blade on a wind turbine hub include hoisting the wind turbine blade towards the wind turbine hub; bringing the wind turbine blade and the wind turbine hub into contact through an adaptable resilient body such that the adaptable resilient body is compressed between the wind turbine blade and the wind turbine hub; reducing a dimension of the adaptable resilient body such that the wind turbine blade approaches the wind turbine hub; and mounting the wind turbine blade to the wind turbine hub. Also, assemblies for assisting in mounting the wind turbine blade to the wind turbine hub and adapted wind turbine hubs are provided.

A wind turbine includes a rotor shaft. The rotor shaft is mounted via a bearing assembly having a first bearing ring and a second bearing ring mounted to rotate in relation to the first bearing ring. A hydrostatically supported first friction bearing segment is disposed on the first bearing ring and interacts with a first friction face that is disposed on the second bearing ring. The first friction bearing segment is received in a receptacle pocket of the first bearing ring such that a first compression chamber is formed between the first bearing ring and the first friction bearing segment. The first friction bearing segment is configured such that a second compression chamber is formed between the first friction bearing segment and the second bearing ring, wherein the first compression chamber and the second compression chamber are connected by a duct that runs through the first friction bearing segment.

A wind turbine, including a main gear box, which is lubricated and/or cooled by oil, and a thermosiphon cooling system for cooling the oil is provided. The thermosiphon cooling system solves the main challenges facing the oil cooling systems in wind turbines. The high efficiency of the evaporation heat transfer mechanism gives the capacity to transfer the required heat load in relatively smaller size system. In this way, installation space is reduced. The thermosiphon cooling system has no service requirements over the lifetime of the wind turbine since the thermosiphon cooling system has no moving parts. Costs are saved since the simplicity of the thermosiphon cooling system adds a big value to the system business case.
