以弹性流体动力润滑理论为基础 ,建立了圆锥轴承滚子端面与内圈挡边间膜厚的计算模型。对现有膜厚的计算方法 (直接迭代法 )进行了改进 ,提出了该模型的复合迭代法。通过对圆锥轴承挡边膜厚的计算表明 ,该方法的求解误差小 ,收敛速度快 ,是一种有效的求解方法 Based on the theory of elastic fluid dynamic lubrication, a calculation model of the film thickness between the conical bearing roller face and the inner ring rib is established. The existing method of calculating the film thickness (direct iteration method) is improved, and the compound iteration method of the model is proposed. The calculation of the film thickness of the conical bearing ribs shows that this method has the advantages of small solution error and fast convergence speed, and is an effective solution method
