中小型水轮发电机组通常使用的滑动轴承都是合金轴承。作为内衬所用的合金,都应当具备磨擦系数小,不研轴的性能。合金轴瓦通常在装配时刮研,这就不可能使轴颈和轴瓦面结合得十分完好,在与主轴刮研后,要求轴瓦合金在受轴压力下能自动变形,保证与轴颈接触良好。另外,在正常运行中,一旦有点杂质带进轴瓦内,要能 The plain bearings commonly used for small and medium-sized hydro-generator sets are all alloy bearings. As lining the alloy used, should have a small friction coefficient, not the performance of the shaft. Alloy bearing bushings are usually scraped during assembly, which makes it impossible to combine the journal and bearing surface perfectly. After scraping with the spindle, the bearing alloy is required to deform automatically under axial pressure to ensure good contact with the journal. In addition, in normal operation, once a little impurities into the bearing, to be able to
