摘要

介绍了我国铁路轨道车辆滚动轴承的使用数量、使用状况和寿命管理的一般原则，概述了滚动轴承疲劳寿命规律及发展历程，整理归纳机车车辆滚动轴承的故障损伤类型，图示了轴承寿命一般趋势以及各种寿命之间的关系；研究铁路轴承剩余寿命规律，并计算批量轴承可利用工作能力总量及剩余寿命的运用风险，指出修复轴承与新造轴承的差异；计算了剩余寿命运用的经济价值，提出滚动轴承在阶段运用后，检测修复的可用性、可靠性和运用风险，建议对机车车辆滚动轴承寿命管理科学化及成本、风险的优化。

Abstract

The number of rolling bearings used in railway rolling stock and their application status and general principles of life management was enumerated, and the fatigue life law and development history of deve lopment bearings was introduced. The basic failure damage model of rolling bearing for locomotive and rolling stock was studied and sorted out, display the general life trend of rolling bearing and the relationship between various lives. The remaining life law of railway bearing was studied, and the total available working capacity of batch bearing and the operational risk of remaining life were calculated. The difference between repairing bearing and newly built bearing was pointed out. The economic value of remaining life was calculated, and the feasibility, reliability and operational risk of rolling bearing repair after stage operation were tested. It was suggested that the life management of rolling bearing for locomotive and rolling stock is scientificed and the cost and risk is optimized.
