ABSTRACT:
A shutheight adjustment assembly of a mechanical press including an adjustment nut rotatably connected to an adjustment screw. Hydrostatic bearing pads are provided below the adjustment nut to reduce frictional forces associated with nut rotation and to provide a squeeze film thickness to withstand large press loadings. A hydraulic chamber supplied with pressurized fluid is positioned above the adjustment nut and produces a preload force on the hydrostatic bearing pads. Hydrostatic bearing pads are also arranged radially outward of the adjustment nut to radially center the nut during operation. A hydraulic chamber between the adjustment nut and screw may be furnished to resist bolster rebound during press operations.
