Nacelle for wind turbine

The invention relates to a nacelle (2) for a wind turbine (1), the nacelle (2) comprising:-a nacelle shell (4); -a rotor hub (6); a rotor bearing device (8) for bearing the rotor hub (6) on the nacelle housing (4), the rotor bearing device (8) having at least one inner ring element (12) and at least one outer ring element (13), at least one oil-lubricated sliding bearing element (14) being formed between the inner ring element (12) and the outer ring element (13). In the nacelle housing (4) and/or in the rotor hub (6), a lubricating oil groove (18) is formed for receiving lubricating oil (19) for the sliding bearing element (14). The lubricating oil tank (18) can be filled with lubricating oil (19) up to a lubricating oil level (20), at least one section of the rotor bearing (8) being arranged vertically in the lubricating oil tank (18) below the lubricating oil level (20). 本发明涉及一种用于风力发电设备(1)的机舱(2)，该机舱(2)包括：-机舱壳体(4)；-转子毂部(6)；-转子支承装置(8)，用于将转子毂部(6)支承在机舱壳体(4)上，其中，转子支承装置(8)具有至少一个内部的环形元件(12)和至少一个外部的环形元件(13)，其中，在所述
