为避免推力反转,建议尽可能在转轮(推力盘)的每一侧使用两个箔片推力轴承(1 CW + 1 CCW)。

Foil Thrust Air Bearing Flow Dynamics

Figure 1: Flow dynamics depicting circulating effect of air in/out of the bearing, crucial to its operation. Quantification of circulation, influenced by ambient pressure, is evident, showcasing the bearing's responsiveness to varying environmental conditions. Calculations based on ambient pressure of 1 atm reveal a proportional relationship between pressure and load-carrying capacity. Advanced aerodynamic design eliminates the need for external pressurization, streamlining functionality.

箔轴颈空气轴承

OAV 箔片径向空气轴承具有精确的外径,应根据需要过渡安装到外壳中。如果必须使用底板,请使用定位销和/或螺纹螺钉,如下图所示,通过轻压配合固定轴承。

底板、轴承箱、OAV 箔轴颈空气轴承和所有相关组件应仅使用异丙醇清洁,以去除杂质和灰尘颗粒。
