GREASE COLLECTOR, WIND TURBINE NACELLE AND METHOD FOR COLLECTING EXCESS GREASE

摘要

A grease collector (15) is described, which is connectable to a wind turbine nacelle (3). The grease collector (15) comprises a channel (16) with a flexible side portion (17) for providing a sealing between the nacelle (3) and a wind turbine tower (2). Moreover, a wind turbine nacelle (3) and a wind turbine (1) comprising an inventive grease collector (15), and a method for collecting excess grease which is emitted from a yaw system (7) of a wind turbine (1) are provided.
