Chapter 5 Compound Material, the Great Unknown

A unique fusion of theoretical and practical knowledge, “Changes in Plain Bearing Technology”, by Rolf Koring, covers a meaningful range of expertise in this field. Drawing from years of experience in design development, materials selection, and their correlation to real-life part failure, this title, co-published by SAE International and expert Verlag (Germany), concentrates on hydrodynamic bearings lined with whitemetals, also known as Babbits. Written under the assumption that even the most mature body of knowledge can be revisited and improved, “Changes in Plain Bearing Technology” is a courageous and focused approach to questioning accepted test results and looking at alternative material compounds, and their application suitability. The process, which leads to innovative answers on how the technology is transforming itself to respond to new market requirements, shows how interdisciplinary thinking can recognize new potential in long-established industrial modus operandi. Tackling the highly complex issue of component failure, “Changes in Plain Bearing Technology” addresses the basics of hydrodynamic plain bearings while shedding new light on the performance of compound materials, including the limits of measurable fatigue strength, the lining materials of the future and damage evaluation. Main points of interest in this book are: • The advantages of hydrodynamic plain bearings • Backing and lining materials • Compound materials: the great unknown and new conclusions • Investigations on test rigs • Quality standards for plain bearings • Assembly and operations • Damage of plain bearings and its consequences • The future of the technology “Changes in Plain Bearing Technology” is a must-read for those looking for new solutions in this high-impact area of mechanical engineering.
