Abstract
A hydrodynamic oil film system is disclosed for developing a lubricant film between a flywheel and an associated stationary bearing during press machine operation. Hydrostatic bearing pads formed in the inner bearing surface of the stationary bearing are used to receive pressurized fluid. A hydrodynamic effect is produced during rotation of the flywheel enabling fluid transmitted into the hydrostatic bearing pads to be provided within the clearance between the flywheel and the stationary bearing. In another aspect, an oil film is produced between the keyed sections of the stationary bearing and an adjacent bearing support block to which the stationary bearing is interengaged for anti-rotational purposes, thereby preventing pounding out of the material from the key surfaces.
