Rotordynamic Performance of a Shaft With Large Overhung Mass Supported by Foil Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents the theoretical and experimental rotordynamic evaluations of a rotor–air foil bearing (AFB) system supporting a large overhung mass for high-speed application. The proposed system highlights the compact ...
Design of Novel Gas Foil Thrust Bearings and Test Validation in a High-Speed Test Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Small gas foil bearings (FBs) with shaft diameter below 25 mm can find many applications in air compressors for fuel cells, electrical turbo chargers, small unmanned air vehicles, turbo alternators, etc. These small machines ...
Novel Thrust Foil Bearing With Pocket Grooves for Enhanced Static Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The integration of foil bearing technology into high-speed oil-free machines has been slow in progress, in part, due to the low load-carrying capacity of the foil thrust bearing. It is crucial this issue is addressed through ...
Static Performance of a Hydrostatic Thrust Foil Bearing for Large Scale Oil-Free Turbomachines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a novel design of a hydrostatic thrust foil bearing (HSTFB), with an outer diameter of 154 mm, along with simulation and test results up to a specific load capacity of 223 kPa (32.3 psi). This bearing ...
