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.
