摘要： A bearing assembly for use on a rudder shaft of a vessel or boat wherein the shaft has a thin cylindrical rubber sleeve that encompasses it. The outer peripheral surface of the rubber sleeve is bonded to a fiberglass ring which is bonded to an elongated annular rubber member which is in sliding contact with the inner peripheral surface of a teflon ring which in turn is bonded to the inner peripheral surface of a fiberglass sleeve. The latter sleeve in turn is bonded to the inner periphery of the upper end of a housing that is attached to the hull of a vessel. The lower portion of the rudder shaft has secured to it an annular rubber bearing that is in frictional sliding contact with a teflon ring that is secured to the inner peripheral surface of the lower end of the housing.

摘要： A composite (10) which presents a layer (20) of ultra-high molecular weight polyethylene as the wear resistant surface. The polyethylene layer (20) is secured to a metallic backing plate (12) by virtue of an elastomeric layer (13) that is interposed between the metallic backing plate (12) and the polyethylene layer (20) and is bonded to each without the polyethylene and the metallic backing plate being otherwise bonded to each other. This configuration provides a means by which to mount a wear resistant polyethylene layer from a metallic backing plate and at the same time accommodate the difference between the disparate coefficients of expansion of polyethylene and metal. The composite (10) can be readily formed by placing a layer of uncured elastomer (13) on the prepared surface (11) of a metallic backing plate (12), spreading an ultra-high molecular weight polyethylene powder (15) over the uncured elastomer and heating the thus assembled components, preferably under pressure, to cure the elastomer and melt the polyethylene powder. When cooled, and the melted powder (15) coalesces into polyethylene layer (20), the resulting wear resistant composite can be formed by conventional cold working processes into desired configurations.
