摘要： PROBLEM TO BE SOLVED: To provide a method of controlling the instability in fluid film bearings by using a magnetic bearing in combination with a fluid film bearing.SOLUTION: The fluid film bearing 18 serves as the primary load carrying bearing and the magnetic bearing assembly 12 controls the instability of the fluid film bearing. This efficient combination results in bearings that can be used at high speeds without having neither stability nor reliability problems. An alternative method of controlling the instability in fluid film bearings is to disturb the flow in the axial direction. A sleeve (journal) bearing, for example, can be manufactured such that the bearing axis is skewed with the shaft axis or a variable geometry bearing can be manufactured to allow for bearing angular misalignment.

解决方案：流体膜轴承18用作主负载承载轴承，并且磁轴承组件12控制流体膜轴承的不稳定性。这种有效的组合导致可以在高速下使用而不具有稳定性和可靠性问题的轴承。控制流体膜轴承不稳定性的替代方法是扰乱轴向流动。例如，可以制造套筒（轴颈）轴承，使得轴承轴线与轴线相互倾斜，或者可以制造可变几何轴承以允许轴承角度未对准。版权所有（C）2012，JPO＆INPIT
