    摘要:

    提出了一 种基于蠕动传输作用的新型行波液体静压轴承。首先基于行波液体静压轴承原理,建立了轴 承原理验证装置。然后基于差动螺纹机构建立了轴承面倾斜调整机构,实现轴承的完全 上浮 。利用所开发的轴承验证装置,实验研究了行波液体静压轴承在上浮方向上有导轨时的轴承 承载能力,证明了行波液体静压轴承及其稳定方法的可行性,并给出了驱动参数,例如:驱 动电压和驱动频率,以及轴承间隙高度对轴承浮力稳态值的影响规律。

    Abstract:

    Liquid bearing utilizing traveling waves, which does not need external pressurized source while still achieving load capacity of conventi onal hydrostatic bearings, is a novel hydrostatic bearing based on peristaltic t ransport. Based on the innovative bearing principle, a prototype is developed. And its inclination adjustment apparatus employing differential s crew is developed in order to make the bearing completely float. Experimental re s ults reveal that the prototype successfully generates a steady periodic floating force with positive steady state value. The feasibility of the bearing princip le and its steady method by actively controlling transient bearing clearance hei ght is confirmed by experiments. Experiments are also conducted to investiga te the effect of driving parameters, such as driving voltage and frequency, a s well as bearing clearance height on the steady state value of floating force.
