    Themain purpose ofthis bo ok is to promote a better appreciati

    increasingly important role played by tribology at the desig

    engineering.

    It

    shows

    how

    algorithms developed

    from

    the

    basic

    of

    tribology can be used in a range of practical applications.

    The

    book

    is

    planned

    as a

    comprehensive

    reference and

    source

    willnot only be

    useful

    to p ractisin g designers, researchers and po s

    students, but will also find an essential place in libraries ca

    engineeringstud ents on degree courses in unive rsities and polytec

    com pulsory subject. This m ay be regarded as a m ajor cause of th

    between the

    publication

    o f new findings in

    tribology

    and

    their a

    in industry. A further reason for this time-lag is the fact that

    tribologists fail to presen t their results and ideas in terms of prin

    concepts that ared irec tly accessible and appealing to the design

    It is hoped that the procedures and techniques of analysis ex

    this book

    will

    be

    found helpful

    in applying the principles of tribol

    design

    of the machine elements com m only

    found

    in m echanical d

    systems.

    It is

    designed

    to

    supplement

    Engineering Science

    in

    tribology (well known

    to

    practising engineers),

    ing the basic p rinciples, giving the ba ckgro und and explaining the

    of the practical procedures that are recommended. On a n

    The material is grouped according to

    applications:

    elements

    mechanics, tribology of lower kinematic pairs, tribology of hi

    elements.

    The concept of tribode sign is introd uce d in Chapter 1.

    devoted to a

    brief

    discussion of the basic principles of tribolog y,

    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

    inv olut e gears.

    At

    the end of

    Chapters

    2-8

    there

    is a list of

    books

    and

    selected papers

    providing further reading on matters discussed in the particular chapter.

    The choice of

    reference

    is rather personal and is not intended as a

    comprehensive literature survey.

    The book is based largely on the notes for a course of lectures on

    friction

    wear

    and

    lubrication application

    to

    m achin e design given

    to

    students

    in the

    Dep artment of Mechanical Engineering Technical U nive rsity of Gda nsk

    and in the

    M echanical E ngineering Departmen t Brunei University.

    I would like to express my sincere appreciation to some of my

    former

    colleagues from theTechnical Un iversity ofGdansk wheremy owns tudyof

    tribology started.

    I owe a

    particular debt

    of

    gratitude

    to Dr B. J.

    Briscoe

    of

    the

    Imperial College

    of

    who

    helped

    me in

    many

    different

    ways

    to

    continue

    my

    research

    in

    this subject. Finally special
