Patent number: 7222425Abstract: A journal bearing has a lining of bearing metal applied to a steel backing. The surface of the lining is laser peen hardened to locally increase the hardness and the seizure resistance of the lining. The underlying core of the lining is unaffected and maintains good conformability of the lining. The overall lining thus possesses both good seizure resistance and conformability.Type: GrantFiled: June 27, 2005Date of Patent: May 29, 2007Assignee: Federal-Mogul World Wide, Inc.Inventor: Warren J. Whitney, Jr.

Patent number: 6854183Abstract: A lead-free bearing includes a bronze matrix powder metal bearing layer bonded to a steel backing a fully densified. The bearing material has about 8 to 12% by weight tin, about 1 to less than 5% by weight bismuth, and about 0.03 to 0.08% by weight phosphorus, with the balance being copper. The tin is soluable in the copper to yield the bronze matrix, and the bismuth exists as finely dispersed, undissolved islands through the matrix. Such bearings exhibit physical properties comparable to or better than those of traditional bronze-lead bearings and improved wear in seizure properties.Type: GrantFiled: December 8, 2003Date of Patent: February 15, 2005Assignee: Federal-Mogul World Wide, Inc.Inventors: Robert L.

Patent number: 6833339Abstract: A bi-metal aluminum bearing includes an aluminum-based bearing layer, a steel backing, and an intermediate aluminum-based layer that has a thickness of from 60 to 120 micrometers positioned between the aluminum-based bearing layer and the steel backing. The intermediate layer has a yield strength that is less than that of the aluminum-based bearing layer and is preferably of pure aluminum. The aluminum-based bearing layer has a fine microstructure which imparts a very high level of conformability while retaining good fatigue strength. The aluminum bearing layer generally includes 4% to 20% by weight lead or tin, up to 26% by weight silicon and up to 2% by weight of any of the elements magnesium, manganese, nickel, zirconium, zinc, copper, or chromium with the remainder of the bearing layer being aluminum.Type: GrantFiled: April 4, 2003Date of Patent: December 21, 2004Assignee: Federal-Mogul World Wide, Inc.Inventors: Warren J.

Publication number: 20040074335Abstract: A connecting rod for an internal combustion engine comprises a non-ferrous powder metal material body of a first composition. The body has a small end opening and a large end opening. A bearing surface portion surrounds the large end opening and is fabricated of a non-ferrous powder metal material of a second composition different than the first non-ferrous composition. The first and second compositions are compacted and sintered together with the second material of the bearing surface portion surrounding and being localized about the large and opening.Type: ApplicationFiled: October 22, 2002Publication date: April 22, 2004Applicant: FEDERAL-MOGUL WORLD WIDE, INC.Inventor: Warren J.

Patent number: 6511226Abstract: An aluminum thrust washer that has a wrought aluminum matrix that includes from 2 to 20 weight percent silicon, 0.1 to 4 weight percent of copper, with the remainder pure aluminum. The aluminum thrust washer is formed of a mono-metal structure without a backing layer. The wrought aluminum matrix has mechanical properties such that the aluminum matrix wears away, leaving silicon particles exposed at a thrust face of the washer, such that the density of silicon particles is continually increasing as the thrust washer is utilized.Type: GrantFiled: September 4, 2001Date of Patent: January 28, 2003Assignee: Federal-Mogul World Wide, Inc.Inventors: Ronald Joseph Thompson, Warren J.

Patent number: 5536587Abstract: A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 2.5% Si, 2% Pb, 0.8% Cu and 0.2% Cr on a weight-percentage basis. The tin has an average particle size less than 5 microns and the silicon has an average particle size less than 5 microns. The alloy may be formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip can be pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing.Type: GrantFiled: August 21, 1995Date of Patent: July 16, 1996Assignee: Federal-Mogul CorporationInventor: Warren J.

Patent number: 5365664Abstract: A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 4% Si, 2% Pb and 1% Cu on a weight percentage basis. The tin has an average particle size less than five microns and the silicon has an average particle size less than 3.5 microns. The alloy is formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip is pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing. During the pressure bonding step the thickness of the aluminum alloy strip is significantly reduced while the thickness of the steel strip remains essentially unchanged.Type: GrantFiled: June 22, 1993Date of Patent: November 22, 1994Assignee: Federal-Mogul CorporationInventor: Warren J.
