摘 要： A design for a low profile hydrostatic rotary bearing is presented that utilizes a new type of self-compensation that allows a large number of bearing pockets to be present with only a few precision round parts, thus allowing high hydrostatic averaging with relatively low design complexity. A key feature of this design is that it does not use capillaries or orifices or a complex network of passageways to route fluid. The design consists of five easily assembled round parts which can be manufactured by cylindrical grinding. A seal is incorporated which prevents fluid leakage and creates a closed system. The theory of operation is discussed along with manufacturing considerations. Tests show that the rotary bearing has high stiffness, and achieves a high degree of averaging, resulting in a radial error motion of 0.05 μm from components ground to an accuracy of only 2.5 μm.

本文提出了一种低剖面静压旋转轴承的设计，采用了一种新型自补偿结构，可在仅使用少量精密圆形零件的情况下容纳大量轴承凹槽，从而实现较高的静压平均效果，并具有相对较低的设计复杂度。该设计的关键特点是不使用毛细管、孔口或复杂的通道网络来引导流体。其结构由五个易于组装的圆形部件组成，可通过圆柱磨削加工制造。设计中还集成有密封装置，可防止流体泄漏，形成封闭系统。文中阐述了其工作原理及制造方面的考虑因素。测试表明，该旋转轴承具有很高的刚度，实现了高度的流体平均分布，使得在精度仅为2.5微米的部件上，径向误差运动仅为0.05微米。
