摘要
介绍了我国3种6轴货运电力机车轴箱轴承的设计方案,计算对比了每个方案中各个轴承的额定动载荷和额定寿命;阐述了NJ2232WB、NU2232WB及NUHJ2232WB系列圆柱滚子轴承优越的性能及其在国内的使用情况。
This article mainly presents the design project of the axle - box bearing for six - axle freight electric locomotive in our country, and calculate and analyses the dynamic load ratings and the rating life of every bearing, and also expounds the predominant performance and application instance of NJ2232WB, NU2232WB and NUHJ2232WB series columned rolling beating in our country.
