The present invention provides a method for lubricating a gearbox of a wind turbine. The gearbox comprises a plurality of gears and shafts supported by bearings of which at least one is a plain bearing. The gearbox furthermore comprises a lubrication system with a mechanical pump and an electrical pump for feeding the gears and bearings with lubricant, wherein a difference between volume capacity of the mechanical and electrical pump is maximum 40%. The method comprises controlling at least one valve for during start-up of the gearbox feeding lubricant to the bearings by means of the electrical pump, during normal operation of the gearbox feeding lubricant to the bearings and the gears by means of the electrical pump and the mechanical pump, and during absence of electrical power supply feeding lubricant only the bearings by means of the mechanical pump. |
