Storage system for a wind turbine comprising a rotatable scraper and a stationary scraper

摘要

The present invention relates to a storage system (100) for a wind turbine. The storage system (100) comprises a stationary ring (110) including a first axial front surface (111), a rotatable ring (120) to which a hub of the wind turbine is attachable, a rotatable scraper (130) attached to the rotatable one Ring (120) is fixed, and a stationary scraper (140). The stationary ring (110) carries the rotatable ring (120), the rotatable ring (120) enclosing the stationary ring so that the rotatable ring (120) is rotatable about the stationary ring (110). The rotatable scraper (130) abuts the first axial front surface (111) such that by rotation of the rotatable ring (120), the rotatable scraper (130) extends past the first axial front surface (111) to remove grease from the first axial front surface (111) of the stationary ring. The stationary scraper (140) and rotatable scraper (130) are arranged relative to one another in such a manner that, as the rotatable ring (120) rotates, the rotatable scraper (130) rotates once per revolution of the rotatable ring (120). with respect to the stationary ring (110), moving past the stationary wiper (140) such that the stationary wiper (140) strips the grease from the rotatable wiper (130).
