摘要首先建立了圆锥滚子轮毂轴承内部载荷的计算模型,同时使用此模型以及DPF算法对某2代圆锥滚子轮毂轴承在不同工况下内部各滚子的载荷进行了求解。在此基础上使用一种严于国家标准的计算方法对其进行寿命计算。最后通过计算数据得到了预紧力-寿命特性曲线,确定了此轮毂轴承的最佳游隙范围。 A model is deduced for analyzing the load distribution of tapered roller hub bearings.On the basis of this model and DFP iterative method,numerical computations on the contact load under different working condition are car-ried out for a certain exampled second generation hub bearings.Then compared to the national standard,a more specif-ic method of life calculation is used to obtain its lifespan.Finally a preload-life indicatrix is plotted,and the sugges-ted clearance interval is given.
