摘　　要：在对圆锥滚子轴承进行受力分析的基础上,利用弹性流体动力润滑理论,得到承载最大滚子与内、外滚道间的最小油膜厚度计算式,并将其引入滚动轴承阻尼计算过程,建立了包含轴承滚子阻尼和油膜阻尼的轴承综合阻尼计算模型。The damping of tapered roller bearing is studied. The numerical expression of minimal lubricant film thickness between the heaviest loaded roller and raceways is obtained through mechanics analysis and EHL theory, and then this expression is used to establish the calculating medel of the roner bearing damping, considering both material and lubricant film damping.
