New Bearing Design Concept An Innovative, U.S. Army, Design Concept for Tactical Vehicle Bearings and Universal Joints 973178

A radically new approach to the design of bearings demonstrated feasibility in a U.S. Army SBIR1 program. It was first applied to universal joints on the HMMWV (High Mobility Multipurpose Wheeled Vehicle) in order to maximize the concept's performance benefits and optimize vehicle cost savings. The program2 was one of five recipients of the U.S. Army's 1995 SBIR Phase II Quality Awards. The concept has been issued three patents3. This paper presents the theory and documents HMMWV field test results in the successful development of a new universal joint with bearings that eliminate field lubrication and provide a major reduction in maintenance.
