摘要
根据我国铁路机车的现状 ,从结构优化、新材料的应用、加工工艺的改进等几个方面系统地阐述了提高铁路机车轴承使用寿命及加强其综合机械性能的措施。通过与国际先进的轴承技术的全面比较 。
Based on the current situations of domestic railway locomotives, the measures of increasing service life of railway locomotive bearings and strengthening their comprehensive mechanical properties were systematically elaborated in terms of structural optimization, application of new materials, and improvement of machining procedures. Through the comprehensive comparison with international advanced bearing technologies, it was concluded that domestic railway locomotive bearings have technically interfaced with international ones.
