轴是涡轮机等设备的心脏部件,造价非常昂贵。为了保护轴,一般用滑动轴承来支撑。轴瓦内表面用耐磨巴氏合金,这样由于轴颈与巴氏合金的硬度(HB)相差很大,轴的磨损很小;同时当设备检修时,轴瓦由于是双片结构,很容易装卸,随着现代工业向高速重载方向发展,都十分关注滑动轴承的流体动力特性。 Shafts are the heart parts of turbines and other equipment, which is very expensive. In order to protect the shaft, the general use of sliding bearings to support. Bearing bush inner surface with wear-resistant Babbitt alloy, so that due to journal and Babbitt hardness (HB) a great difference, the shaft wear is small; the same time when the equipment overhaul, the bearing is double-sheet structure, it is easy loading and unloading, With the development of modern industry to high-speed heavy-load direction, great attention has been paid to the hydrodynamic characteristics of plain bearings.
