摘要
The present subject matter relates to a gearbox system for a wind turbine. The gearbox may have a gearbox housing defining an inner gearbox volume. The gearbox system further comprises at least one reservoir for storing lubricant and a lubricant provision arrangement. In addition, a lubricant return arrangement is provided. Thus, the gearbox system comprises a lubrication cycle, in particular a closed lubrication cycle, wherein lubricant is provided from the reservoir through the lubricant provision arrangement to lubrication locations of the gearbox, and is subsequently returned to the reservoir passing through the lubricant return arrangement. Furthermore, the gearbox system includes an aeration arrangement which is connected to the gearbox volume and which has specifically configured restriction means. In order to obtain a beneficial operational behavior of the gearbox system, the gearbox system, in particular the reservoir, the pump, the lubricant provision arrangement and/or the aeration arrangement, is/are configured such that a lubricant flow, having an appropriate pressure and flow rate, is provided from the reservoir to each lubrication location, when the pump is operative; further, the gearbox volume gets flooded with lubricant from the reservoir, when the pump is or becomes inoperative.
