Evaluation of Polymeric Thrust Elements for Powertrain Applications: Methods, Apparatus, and Initial Results

A method and equipment for the determination of material limits for polymeric thrust elements is presented along with initial data based on the system. Methods are presented to better simulate drive train thrust element operation on equipment that utilizes production ready mating components under actual load, speed, and lubrication conditions. Initial results for limited materials are presented. This study allows for a more complete understanding of the effects of the product of pressure and velocity (PV) on material wear and frictional behavior for drive train applications of thrust elements.
