摘要： A pneumatic bearing arrangement comprising an outer element and an inner element which both have generally conical configurations. The elements also have concave and convex bearing surfaces, respectively. The elements are disposed in generally concentric relation and define a generally conical bearing space therebetween. A plurality of nozzles are provided on the elements and open adjacent to the bearing surfaces of the elements. A shaft having a generally conical journal member with an inner and outer face is rotatably supported by the bearing space such that a gap exists between the journal and the inner and outer bearing surfaces. When air is jetted into the bearing space through the nozzle air films are created for maintaining the journal floating between the bearing surfaces without contacting either of the surfaces. The outer element, inner element and journal member can be formed with a substantially bell-shaped configuration to increase the bearing surface for both thrust and radial loads. A plurality of journal members can be provided at spaced locations along a shaft which are accommodated by respective pairs of outer and inner elements spaced along the arrangement. The journal members are maintained in a balanced position within the bearing spaces.
摘要翻译：一种包括外部元件和内部元件的气动轴承装置，其均具有大致圆锥形的构造。元件还分别具有凹凸承载面。这些元件以大致同心的关系设置，并且在它们之间限定一个大致圆锥形的轴承空间。多个喷嘴设置在元件上并且相邻于元件的支承表面打开。具有内表面和外表面的具有大致锥形的轴颈构件的轴由轴承空间可旋转地支撑，使得在轴颈与内外轴承表面之间存在间隙。当通过喷嘴将空气喷射到轴承空间中时，产生用于将轴颈保持在轴承表面之间的空气膜，而不接触任一表面。外部元件，内部元件和轴颈构件可以形成为具有基本上钟形的构造，以增加推力和径向载荷的支承表面。多个轴颈构件可以沿着轴设置在间隔开的位置处，所述轴由相应的沿组件间隔的外部元件和内部元件对容纳。轴承座在轴承空间内保持平衡的位置。
