摘　　要：对汽车驱动桥主减速器圆锥滚子轴承进行弹性流体动力润滑分析,根据润滑油的物理参数和滚子承受的载荷,求出了油膜压力和摩擦因数。然后利用有限元软件对受载荷最大的滚子进行了有限元分析,得出了滚子在外部载荷和惯性力作用下的接触应力分布,得出驱动桥主减速器工作时的惯性力对圆锥滚子轴承的影响是必须考虑的因素。The elastic hydrodynamic lubrication is analyzed for tapered roller bearing of automobile rear axle under high - speed heavy load state. According to the parameters of lubricant and the lead on rollers, the oil film pressure and fricafion factor are solved. Then, the element analysis is done on roller bearing heaviest lead, and the contact stress distribution on rollers is obtained under applied lead and inertia force that must be taken into consideration.
