ABSTRACT:
A bearing assembly in which the bearing surface is composed of ice, and lubrication is provided by the frictional action of a shaft or other supported member against the frozen surface, which liberates a thin film of liquid. A collar, composed of a synthetic resin polymer material, such as the material sold under the trademark Teflon, is mounted on the shaft and rotates with the shaft against the liquid film on the frozen bearing surface. A chill conductor ring, composed of aluminum, surrounds the collar, forming a chamber therebetween for receiving the freezable liquid, and a refrigeration system circulates coolant through passages in the conductor ring to lower its temperature and freeze the liquid into a bearing surface.
