摘要
多孔质材料被用来作空气静压轴承的节流器在过去已经广为报道了。多孔质材料节流器比传统的节流器具有一些显著的优点,如设计和制造简单、很高的承载能力和刚度、更优越的阻尼特性以及低成本。甚至更加复杂的几何结构如球轴承、空气静压丝杠也能够很容易获得。到目前为止,止推轴承尤其是圆板状的止推轴承是进行理论分析的最简单的几何模型,同时也是报道最多的。本文首先介绍多孔质空气静压轴承的理论,接着着重介绍多孔质止推轴承的理论发展。最后,作者讨论了关于多孔质介质的进一步研究的方向。
The use of a porous material as the restrictor in aero - static bearings has been well reported in the past. Its many advantages over conventional restrictors are the simplicity of design and manufacture, higher load capacity and stiffness, superior damping characteristics and low cost. Even complicated bearing geometries, such as spherical bearings or aerostatic leadscrews, can be achieved without difficulties. Thrust bearings, especially in a circular form, are by far the simplest geometry for theoretical analyses, and are therefore the most widely reported. The paper presents the theories of porous aerostatic bearings firstly, then emphasizes on the theory development of the porous thrust bearings, and finally talks about the further research about porous medium.
