摘　　要：在变形集中在衬垫上的假设下,基于干涉模型,提出了自润滑关节轴承轴向承载能力的简化模型对PTFE衬垫自润滑关节轴承轴向受载时的接触应力与轴向承载能力进行推导,并利用ANSYS软件进行有限元分析,通过两者结果的比较验证了新模型的准确性。In self-lubricating radial spherical plain bearings with PTFE liner,it is assumed that the deformation is mainly concentrated on the liner.The calculation formulas of contact pressure and axial load capacity for the bearing under axial loads are derived by using a new simplified model based on the interference model.By comparing with finite element analysis(FEA)solutions using software ANSYS,the accuracy of that by the new model is validated.
