模塊化的 空氣軸承設計和安裝指南

典型配置

OAV 箔片推力空气轴承沿外周有四个销槽。轴承箱的底板是 OAV 箔推力空气轴承将用精密定位销安装的地方。

底板、轴承箱、OAV 箔片推力空气轴承和所有相关部件应仅使用异丙醇清洁,以去除杂质和灰尘颗粒。

然后将 OAV 箔片推力空气轴承轻轻压入底板的定位销上,以将轴承牢固地安装在其位置上。

轴应轻松穿过 OAV 箔片推力空气轴承的内径。但推力轴承顶箔与转轮(推力盘)之间应有7.5-12.5微米的轴向间隙。

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)。

CW 和 CWW 方向如下所示。

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。

然后将 OAV 箔轴颈空气轴承轻轻压入底板的定位销上,如下图所示,以将轴承牢固地安装在其位置上。
