摘　　要：针对止推空气轴承的气管扰动问题,设计出一种无摩擦的旋转供气装置,该装置为一基于气体润滑技术的复合空气轴承,通过Fluent软件仿真,计算出装置的径向空气轴承部分和轴向空气轴承部分的承载力,在受力不超出空气轴承承载力的范围时,该装置可以实现无摩擦旋转供气,可消除运动轨迹为圆周的止推供气轴承气管的扰动影响,最终验证了该装置性能可靠。Aiming at addressing air tube disturbance influence of aerostatic thrust bearing, a frictionless revolving gas supply device was developed. This device is a multiple air bearing based on air lubricating technology. By using Fluent to simulate, compute bearing capacity of radial aerostatic bearing part and axial aerostatic thrust bearing part. In the range of acceptable capacity, the device can realize frictionless revolving gas supply, and eliminate air tube disturbance influence of aerostatic thrust bearing which movement track is a circle, thus verify its performance is reliable.
