Rolling Bearing Tribology: Tribology and Failure Modes of Rolling Element Bearings discusses these machine elements that are used to accommodate motion on or about shafts in mechanical systems, with ball bearings, cylindrical roller bearings, spherical roller bearings, and tapered roller bearings reviewed. Each bearing type experiences different kinds of motion and forces with their respective raceway, retainers and guiding flanges. The material in this book identifies the tribology of the major bearing types and how that tribology depends upon materials, surfaces and lubrication. In addition, the book describes the best practices to mitigate common failure modes of rolling element bearings. Discusses important tribological implications surrounding the performance and durability of rolling element bearings Describes how the different types of roller bearings work Explores the reasons behind the failure of roller bearings and presents information on how to mitigate those failures

The renowned reference work is a practical guide to the selection and design of the components of machines and to their lubrication. It has been completely revised for this second edition by leading experts in the area.

Applied Tribology, 2nd edition not only covers tribology in bearings but demonstrates the same principles for other machine components, such as piston pins, piston rings and hydrostatic lifts, as well as in more recent technologies such as gas bearings in high-speed machines and computer read-write devices. Maintaining a balance between theoretical analysis and practical experience with co-authors from academia and industry, this new edition is significantly revised and expanded with new material. Features include; • Two brand new chapters on seals and bearing failure modes and bearing health monitoring techniques • Coverage of new developments in full-film, dry, and partial lubrication; gas bearings; and ball and roller bearings • Design guides based on full Reynolds equation that enable accurate prediction of load capacity, power loss, temperature rise • Comprehensive presentation of important design factors involving material and lubricants. • State-of-the-art presentation and up-to-date references of pertinent scientific and applied topics in tribology • Numerous examples that reinforce the understanding of concepts and provide procedures for the design and performance analysis of components Applied Tribology, 2nd edition provides a valuable and authoritative resource for mechanical engineering professionals working in a wide range of industries with machinery including turbines, compressors, motors, electrical appliances & electronic components. Senior and graduate students in mechanical engineering will also find it a useful text and reference.

Hydrodynamic Lubrication is the culmination of over 20 years close, collaborative work by the five authors and discusses the practical use of the formalization of low pressure lubrication. The work concentrates on the developments to journal and thrust bearings and includes subjects such as: • the dynamic behaviour of plain and tilting-pads • the thermal aspects • the positive and negative effects of non-cyclindricity and shape defects resulting from manufacturing or operation • the effects of inertia • the appearance of Taylor's vortices and of turbulence and their repercussions. The book contains an abundance of test results objectively compared with theoretical conclusions and a chapter on "technical considerations" to ensure that draft mechanisms will work satisfactorily under the imposed conditions. Hydrodynamic Lubrication is an essential reference book for future and practising engineers who want to put hydrodynamic and hydrostatic journal bearings and thrust bearings into operation under conditions of total safety.

Bearings: A Tribology Handbook is a practical guide on bearings, based on materials published in the first edition of the Tribology Handbook. The handbook has been updated matching international requirements. The book is divided in four main parts. The first part is a description of different bearing types and forms pertaining to continuous and oscillatory movements. A selection of journal and thrust bearings as to their different load capacity, performance, and special environmental conditions is explained. The second part deals with the physical properties and load capacity of plain bearings. Other kinds of bearing, such as the dry rubbing bearings; porous metal bearings; grease, wick, and drip fed journal bearings; ring and disc fed journal bearings; steady load pressure fed journal bearings; high-speed bearings; and crankshaft bearings, are considered regarding their performance, maintenance, and suitability to specific conditions. The third part focuses on one type of bearing: the rolling bearing. The selection, composition, shaft and housing design, and fitting and mounting for this type is discussed. The last part explains special bearing types such as slide bearings, instrument jewels (which are a combination of a steel pivot and a synthetic sapphire jewel), and electromagnetic bearings that are essentially powerful electromagnets. The need for surface treatments and coatings is then explained for optimum usage. The handbook is useful for design engineers, mechanical engineers, and material researchers. Mechanical, aeronautical, and automotive students; car mechanics; and those interested in machine and car maintenance will find this handbook a handy reference.

Fundamentals of Tribology deals with the fundamentals of lubrication, friction and wear, as well as mechanics of contacting surfaces and their topography. It begins by introducing the reader to the importance of tribology in everyday life and offers a brief history of the subject. It then describes the nature of rough surfaces and the mechanics of contacting elastic solids and their deformation under load and friction in their relative motion. The book goes on to discuss the importance of lubricant rheology with respect to viscosity and density. Then, the principles of hydrodynamic lubrication are covered with derivations of the governing Reynolds and energy equations. Applications of hydrodynamic lubrication in various forms of bearings — journal bearings, thrust bearings and externally pressurised bearings — are outlined. The important and still evolving subject of elastohydrodynamic lubrication is treated in some detail, both at its fundamentals and its applications in thin shell or overlay bearings, cam-followers and internal combustion engine pistons.The fundamentals of biotribology are also covered, particularly its applications to endo-articular mammalian joints such as hip and knee joints and their arthroplasty. In addition, there is a treatment of the rapidly emerging knowledge of tribological phenomena in lightly loaded vanishing conjunctions (nanotribology), in natural systems and very small devices, such as MEMS and high density data storage media. There is also a new chapter on the rapidly emerging subject of surface texturing to promote retention of microreservoirs of lubricant, acting as microbearings and improving lubrication of otherwise poorly lubricated conjunctions.This book targets the undergraduate and postgraduate body as well as engineering professionals in industry, where often a quick solution or understanding of certain tribological fundamentals is sought. The book can also form an initial basis for those interested in research into certain aspects of tribology.
