摘　　要：以轧钢机用四列圆锥滚子轴承为研究对象,通过计算轴承在不同偏斜角状况下的疲劳寿命,并分析了在偏斜角状况下轴承疲劳寿命的变化趋势,总结出轧钢机用四列圆锥滚子轴承偏斜角对其疲劳寿命的影响,为长寿命重型轴承的设计提供一个技术依据。The paper takes four-row tapered rolling bearing for rolling mill as subject investigated.By calculating the life of a bearing under the different deflection angles, penman analyzed variational direction of bearing＇ s life. This paper summarized the mill to use four-row tapered roller bearings＇s deflection angle to its fatigue life influence, and provided a technology basis for design of heavy-duty bearing.
