风电机组主轴轴承油脂泄漏原因分析及研究

A analysis and Research About Main Shaft Bearing Seals Leak of Wind Turbine

国内广泛应用的双VA型主轴轴承密封结构的设计缺陷是造成主轴承油脂泄漏的主要因素，开发新结构密封并实现在已运行机组中的安装是防止机组主轴油脂泄漏和提升机组健康水平的有效途径。

The double VA seals which applied in wind turbine main shaft bearing have been installed extensively. The design defect is the prime reasons which causes the lubricating oil leaking, new structure have been exploited and used in the operating wind turbine, and this new seals have deal with the oil leaking, the health level have been improved.
