“三峡水轮发电机巨型推力轴承研究”是国家自然科学基金委员会和机械部基金会联合资助的重大科研项目。国内有关单位在攻关过程中最近取得重大新的发现,即采用弹性金属塑料瓦的推力轴承与传统的巴氏合金瓦轴承在润滑机理等方面有很大差别,油膜的速度边界条件以及瓦面的变形特性都有显著不同,经典的 “Three Gorges hydraulic giant thrust bearing research” is the National Natural Science Foundation of China and the Ministry of Machinery Foundation jointly funded major scientific research projects. Recently, the relevant domestic authorities made a major new discovery in the course of tackling the problem. That is, there are great differences between the thrust bearings using elastic metal plastic bushings and the traditional babbitt bearing in terms of lubrication mechanism, the speed boundary conditions of oil film, Deformation characteristics are significantly different from the classic
