Investigation of Bearing Technology
Abstract
This report records and documents Laboratory and Field Test data that demonstrates the superiority of new universal joints that utilize a unique, innovative technological concept. These "GC U-Joint's were tested on the Propeller Shafts of the HMMWV in direct comparison with Standard universal joints. They are interchangeable. The new bearings, named "Geometrically Contoured (GC) Bearings" for their design configurations, are made from powdered metal materials. They eliminate roller needles and balls in bearings. Since the GC design does not require lubrication maintenance, there is no need for the u-joint cross to contain lubrication reservoirs and distribution channels and their input fitting. Their elimination in the "GC Solid" cross enhances the fatigue resistance of the entire universal joint significantly , as well as markedly reducing their manufacturing costs. Field tests confirm the GC Solid U-Joint provides significant wear performance improvement over the HMMWV standard needle rollered universal joint. The innovation is not limited to the universal joint. GC Bearings are interchangeable with standard bearings. They provide improved performance with longer life and do so without lubrication maintenance and at reduced unit costs. GC designed bearings can be used to replace Roller Bearings, Ball Bearings and Sliding (Sleeve) Bearings.
