Abstract

New forms of adjustable fluid film hydrodynamic bearings have shown great potential for controlling the position of rotational centres, irrespective of loading, and suppressing vibration orbits arising from low load instabilities. First tested on a simulated machine tool rotor and spindle system, the principle has also been demonstrated in a large marine gearbox test rig. In both cases the bearing adjustment feature was used to maintain and displace in a pro-active manner the centre of rotation irrespective of loads and changes of load, and to suppress instabilities and vibrations provoked by running at low loads. These and other characteristics could be of significant benefit in a range of fluid film bearing applications when coupled with appropriate management and control systems.
