Abstract
A bearing arrangement comprised of a substrate having a plurality of self-lubricating polyimide graphite-fiber reinforced composite bearing members secured to provide a bearing surface. The bearing arrangement being well suited for use under harsh conditions, including high temperatures, high impacts, and large loads.
Claims17
A bearing arrangement having at least one bearing surface, said bearing arrangement comprising:
- a substrate comprising a component capable of carrying the load of the bearing arrangement and having at least one support surface,
- members comprising a self-lubricating, polyimide graphite-fiber reinforced composite material, attached to said support surface to provide a load bearing structural component of the bearing arrangement and a lubricating low friction film for the substrate, and
- connection means for connecting said members to said substrate.
A pillow block assembly for a molten metal ladle, said block assembly comprising:
- an adapter having an elongated center portion with flanges at opposite ends thereof, said adapter having a bore formed along its longitudinal axis for receiving a shaft;
- two pairs of collar portions, each pair of collar portions fastened to one of said flanges to form a ring around said center portion, said collar portions having inwardly facing annular surfaces and self-lubricating, polyimide graphite-fiber reinforced composite bearing material embedded in said surfaces;
- a pair of half journals forming a cylinder around said center portion, each half journal having an inner surface facing said center portion and an outer surface, said inner surface having self-lubricating, polyimide graphite-fiber reinforced composite bearing material embedded therein for engaging said center portion in a bearing relationship as said center portion rotates relative to said cylinder, and said outer surface having a race;
- and
- a housing which engages with said race of said outer surface of said half journal to hold said pair of half journals stationary relative to said adapter when said adapter is rotated.
