SEALING SYSTEM AND METHOD OF MAINTAINING A CLEAN ENVIRONMENT IN A WIND TURBINE BY ABSORBING LUBRICANT USED IN THE PITCH OR YAW BEARINGS

摘要

A sealing system for a wind turbine comprises first component and a second component positioned proximate the first component and movable relative thereto. An absorbent element is secured to the first component and comprises an oil-absorbent material. A contact member is secured to the absorbent element and comprises a non-absorbent material. The contact member abuts the second component so that lubricant leaking from between the first and second components is collected by the absorbent element. A method of maintain a clean environment in a wind turbine with such a sealing system is also disclosed.
