| 摘要 |
The invention relates to a wind turbine for generating electric power by an air stream (1) onto a rotor (48) rotatable about a rotor axis (2), said rotor comprising a plurality of rotor blades (3, 4) and being coupled via a rotor shaft (5) to a generator (6), wherein a primary transmission (8) is present between the rotor shaft (5) and generator input shaft (7) for multiplication of the rotational speed, wherein the pressure-feed or force-feed lubricating system of said main transmission comprising a lubricating pump (9) enables the supply to components (46, 47) subject to wear, wherein the wind turbine (10) has an emergency pump (11) for lubricant supply, which during normal operation of the wind turbine is not operational and during spinning operation and/or a power failure can be connected and which is operated by the rotating rotor (48). |
