| 摘 要： |
Wind turbines have improved in terms of reliability over the past ten years, but they still experience crucial and expensive tribological issues that shorten their intended lifespans. Most turbines require significant repairs or complete replacements of the tribo components in the 5-to 7-year range. The pricey gearboxes have high repair rates, which greatly raises the operating costs for wind turbines and the cost of wind energy. Currently, various bearings in the turbine are lubricated by automatic lubrication systems with the necessary oil filters to ensure cleanliness. The commonly used lubrication methods for wind turbine bearings are centralized lubrication, oil-air lubrication, oil mist lubrication, and oil bath lubrication. There are similarities between wind turbines and spacecraft-moving mechanical systems. Most spacecraft are designed to work for decades in a remote environment without periodic maintenance. Spacecraft use efficient lubrication systems for their moving mechanical systems to provide the required lubricant to the bearings for the required life. Depending on the lubrication requirements, proven active and passive lubrication systems are employed in spacecraft. This paper reviews the lubrication issues of the wind turbine in comparison with the spacecraft and proposes a few lubrication systems that are successfully performing in spacecraft, intending to improve the reliability of wind turbine tribo-systems.
过去十年间，风力涡轮机的可靠性有所提升，但仍存在一些关键且昂贵的摩擦学问题，导致其使用寿命缩短。大多数涡轮机在5到7年的时间内需要对摩擦部件进行重大维修或完全更换。昂贵的齿轮箱维修率较高，显著增加了风力涡轮机的运行成本以及风电的成本。目前，风力涡轮机中的各种轴承均采用自动润滑系统，并配备必要的油滤器以确保油液清洁。风力涡轮机轴承常用的润滑方式包括集中润滑、油气润滑、雾油润滑和油浴润滑。风力涡轮机与航天器的运动机械系统之间存在相似之处。大多数航天器的设计要求在偏远环境中长期运行数十年，无需定期维护。因此，航天器会为运动机械系统采用高效的润滑系统，以向轴承提供所需的润滑剂，保障其达到预期的使用寿命。根据润滑需求，航天器采用经过验证的主动和被动润滑系统。本文对比了风力涡轮机与航天器的润滑问题，并提出几种在航天器上成功运行的润滑系统，旨在提高风力涡轮机摩擦系统的可靠性。 |
