Book Description
Bearings are widely used in rotating machines. Understanding the factors affecting their reliability and service life is essential in ensuring good machine design and performance. Solving tribology problems in rotating machines reviews these factors and their implications for improved machine performance. The first two chapters review ways of assessing the performance and reliability of rolling-element bearings. The author then goes on to discuss key performance problems and the factors affecting bearing reliability. There are chapters on cage and roller slip, and particular types of failure in equipment such as alternators, condensers and pumps. The author also reviews the effects of such factors as localised electrical currents, seating, clearance, grades of lubricant, axial forces, vibration on performance and service life. The book concludes by reviewing ways of improving bearing design. Solving tribology problems in rotating machines is an essential reference for engineers involved in the design and operation of rotating machines in such sectors as power generation, electrical and automotive engineering. Discusses improved machine performance Examines factors affecting bearing reliability An essential reference for engineers

Book Description
Many of the engineering problems of particular importance to railways arise at interfaces and the safety-critical role of the wheel/rail interface is widely acknowledged. Better understanding of wheel/rail interfaces is therefore critical to improving the capacity, reliability and safety of the railway system. Wheel-rail interface handbook is a one-stop reference for railway engineering practitioners and academic researchers. Part one provides the fundamentals of contact mechanics, wear, fatigue and lubrication as well as state-of-the-art research and emerging technologies related to the wheel/rail interface and its management. Part two offers an overview of industrial practice from several different regions of the world, thereby providing an invaluable international perspective with practitioners’ experience of managing the wheel/rail interface in a variety of environments and circumstances. This comprehensive volume will enable practising railway engineers, in whatever discipline of railway engineering – infrastructure, vehicle design and safety, and so on – to enhance their understanding of wheel/rail issues, which have a major influence on the running of a reliable, efficient and safe railway. One-stop reference on the important topic of wheel rail-interfaces Presents the fundamentals of contact mechanics, wear, fatigue and lubrication Examines state-of-the-art research and emerging technologies related to wheel-rail interface and its management

Book Description
As wear is a surface or near surface phenomenon it has long been realised that the wear resistance of a component can be improved by providing a surface of different composition from the bulk material. Although this book concentrates on surface coatings, the distinction between surface coatings and the process of modifying the surface by changing its composition is not always clear, so some useful surface modification techniques are also considered. Surface coatings for protection against wear, consists of twelve chapters written by different authors, experts in their field. After a brief introductory chapter wear phenomena and the properties required from a coating are addressed. Chapter three covers coating characterisation and property evaluation relevant to wear resistance with an emphasis on mechanical testing of coatings. The next chapter provides an introduction to the various methods available to deposit wear resistant coatings. The following six chapters describe in detail wear resistant coatings produced by various deposition routes. Emphasis is placed on the microstructure property relationship in these coatings. Chapter eleven addresses coatings and hardfacings, produced from welding processes, specifically modern developments such as friction surfacing and pulsed electrode surfacing techniques. The final chapter is dedicated to future trends in both coating materials and coating processes. Surface coatings for protection against wear is essential for anyone involved in selecting coatings and processes and will be an invaluable reference resource for all engineers and students concerned with the latest developments in coatings technology. Essential for anyone involved in selecting coatings and processes, engineers and students Written by an international team of experts in the field

Book Description
There are many occasions when quick solutions to problems in tribology are needed. For example, an understanding of the lubrication mechanism in a racing car engine has led to an improvement in performance. Why does a woman's face cream make her look younger for a time? Tribologists are frequently summoned in legal cases as expert witnesses after people have slipped in public places. Improvements to the human artificial hip joint are also partly a result of extensive tribology research. In order to solve such problems, tribology should be regarded as an important undergraduate course. This book covers tribology in such a way as to provide simple approximate solutions to frequent practical problems. Unlike previous books, which catered for earlier generations of undergraduates, today's students generally have sophisticated computer systems available in their colleges. Therefore, many of the worked and set examples in the book are made easier by using readily available software such as Math CAD. Readers will thus gain practice in using it, and will benefit in general by understanding the mathematical principles involved in the solutions. This book is particularly useful to engineering undergraduates and practicing engineers needing a quick solution to tribological problems.

Book Description
Tribology of Reciprocating Engines documents the proceedings of the 9th Leeds-Lyon Symposium on Tribology held at the University of Leeds, England on September 7-10, 1982. This book emphasizes advances in the working principals of the tribological components that operate with relative motion. The topics discussed include the dynamic analysis of engine bearing systems, measurement of oil film thickness in diesel motor main bearings, and temperature variations in crankshaft bearings. The theoretical and experimental study of ring-liner friction, tribology in the cylinders of reciprocating compressors, and lubricant properties in the diesel engine piston ring zone are also described. This text likewise considers the metallurgy of scoring and scuffing failure, impact of oil contamination on wear and energy losses, and role of tappet surface morphology and metallurgy in cam/tappet life. This compilation is a good reference for triblogists, lubrication engineers, and specialists researching on reciprocating engines.

Book Description
Tribology in Machine Design aims to promote a better appreciation of the increasingly important role played by tribology at the design stage in engineering. This book shows how algorithms developed from the basic principles of tribology can be used in a range of practical applications. The concept of tribodesign is introduced in Chapter 1. Chapter 2 is devoted to a brief discussion of the basic principles of tribology, including some concepts and models of lubricated wear and friction under complex kinematic conditions. Elements of contact mechanics, presented in Chapter 3, are confined to the most technically important topics. Tribology of lower kinematic pairs, sliding element bearings, and higher kinematic pairs are discussed in Chapters 4, 5, and 6, respectively. Chapter 7 contains a discussion of rolling contact bearings with particular emphasis on contact problems, surface fatigue, and lubrication techniques. Finally, Chapter 8 concentrates on lubrication and surface failures of involute gears. This book is planned as a comprehensive reference and source that will not only be useful to practicing designers, researchers, and postgraduate students, but will also find an essential place in libraries catering for engineering students on degree courses in universities and polytechnics.
