摘　　要：通过对哈尔滨电机厂生产的ＱＦＳＮ－２００－２型汽轮发电机所使用的不同种轴承的稳定性情况的分析，阐述了原设计的三油楔轴承稳定性裕度偏低，应换用轴瓦宽度缩短的三油楔轴承或椭圆轴承的原因。By analyzing stabilities of various bearings used in QFSN-200-2 typeturbogenerator manufactured by Harbin Electric Machinery Works, the reasonwhy the margin of stability of the formerly designed three-oil-wedge bearingis low and three-oil-wedge bearing, which has bushs shortened in width, orelliptical bearing should be adopted, is stated in this paper.
