Abstract
A bearing of a wind turbine, wherein the bearing is lubricated with a lubricant for reducing wear and fatigue of the bearing, the bearing is sealed such that the amount of lubricant which is leaking out of the bearing is minimized, is provided. The bearing includes a ventilation device with at least one pressure compensation hole for enabling a pressure compensation between the sealed bearing and the ambient. The ventilation device further includes a compressor unit, which is connected with the pressure compensation hole. Thus, a compressed medium can be selectively blown through the pressure compensation hole to ensure that the pressure compensation hole remains substantially unobstructed such that overpressure within the bearing compared to the ambient is minimized and leakage of lubricant out of the bearing is reduced. A wind turbine including such bearing and an associated method is also provided.
