COMPLIANT PRESSURE ROLLER WITH SHELL SUPPORTED ON TILTABL HYDRODYNAMIC BEARING SHOES LUBRICATED BY A NON-NEWTONIAN FLUID

摘要

A compliant pressure roller (10) for creating uniform pressure at a nip comprises a stationary inner core (12). A plurality of shoes (14) is pivotall" mounted to the stationary inner core. Dividers (16) create a plurality of annular chambers (18) wherein each of the shoes occupies one of the chambers. non-Newtonian fluid (70) fills each of the chambers. A plurality of actuators(66) is connected to at least one of the shoes. A thin, rotatable shell (24) surrounds the plurality of chambers, shoes, and stationary inner core.
