PIVOTED-PAD JOURNAL BEARINGS LUBRICATED BY GAS
In a gas-lubricated bearing system, radial location for a rotuting shaft is usually satisfactorily provided by a plain gas journal bearing. In some applications, however, the pivoted-pad journal bearing may be a more practical proposition. Some exploratory work on self-acting gaslubricated pad bearings is described and shows that they are a reliable and stable alternative to the plain gas journal bearing. Their main disadvantage is associated with manufacture and assembly, both of which are more complicated than with journal bearings. Load- minimum gap curves and pressures within the film were measured; the resultu conform generally with ihe theory of the plane slider for an incompressible fluid. Theoretical expressioms are deduced for the gas film stiffmess and resonant frequency of the various modes of vibration which pad bearimgs are likely to exhibit. Such expressions enable a useful estimate to be made of the operating limits of a pad bearing of given design. (auth)
