Performance of Relative Clearance Ratio of Floating Ring Bearing for Turbocharger-Rotor System Stability

The floating ring bearing (FRB) has been widely used in the field of high-speed rotating machinery such as turbochargers, aviation engines and so on, because of its simple structure, high efficiency and low power consumption. In order to obtain the best ratio between inter-oil clearance and shaft ra...
