A FOUR-BALL MACHINE FOR TESTING ANTIWEAR, EXTREME-PRESSURE PROPERTIES, AND SURFACE FATIGUE LIFE WITH A POSSIBLILITY TO INCREASE THE LUBRICANT TEMPERATURE
Journal Title: Tribologia - Year 2009, Vol 223, Issue 1
Abstract
The authors present a new four-ball machine developed within the scope of the Multi-Year Programme PW-004 Development of innovative systems of manufacturing and maintenance 20042008, coordinated by the Institute for Sustainable Technologies National Research Institute in Radom. The main difference between the new device and the ones having been manufactured by ITeE PIB so far is related to a significant improvement of the research capabilities. The previously manufactured four-ball machine, known as T-02 tribotester, was intended for testing antiwear (AW) and extreme-pressure (EP) properties of lubricants. Another four-ball tribotester, denoted as T-03, was intended only for determination of the surface fatigue life. Neither T-02, nor T-03 machine made it possible to perform runs at an increased and controlled lubricant temperature. The new machine, denoted as T-02U, enables the user to perform all the mentioned tests, both for lubricants and engineering materials. A genesis of the idea of the new four-ball machine, its main units, technical specifications, realized test methods, chosen results of verification testing, potential areas of application, as well as first implementations in industrial and scientific laboratories, are presented.<br/><br/>
