SEGMENTED BEARING CARTRIDGE WITH LOCAL AND CONTROLLED THERMAL EXPANSION
Abstract: a bearing interface assembly configured to accommodate different rates of thermal expansion of a bearing and a housing of an installation site. the bearing interface assembly includes: a metallic sleeve including an outer surface defining a groove and an inner surface defining an aperture configured to cooperate with the bearing, the metallic sleeve configured to expand at a first coefficient of thermal expansion; and a filament-wound composite overwrap seated within the groove of the metallic sleeve, the filament-wound composite overwrap configured to expand at a second coefficient of thermal expansion that is less than the first coefficient of thermal expansion to restrict expansion of the aperture to the second coefficient of thermal expansion.
