Machine Elements in Mechanical Design
Part I : Chapters 1-6, helps students gain an understanding of design philosophies and build on earlier-learned principles of strength of materials, materials science, and manufacturing processes. An extensive coverage of combined stresses and design for different types of loading provides important extensions from the traditional coverage of strength of materials courses, necessary to virtually all following chapters.
Part II : Chapters 7-15, encompasses the design of machine elements that are typically part of a mechanical power transmission: belt drives and chain drives; gears; keys, couplings, and seals; shafts; and rolling contact bearings. But, more importantly, the chapters are tied together to help students see the interrelationships among the individual elements.
Chapter 15: COMPLETION of the DESIGN of the POWER TRANSMISSION, takes the student through the complete design of a gear type speed reducer, from conceptualization, decision analysis, and general layout, to design and analysis of the components tolerances and fits, applied to critical elements, and detail drawings and specifications of the housing and the major components of the reducer. This is a completely new chapter for the third edition.
Part III : Chapters 16-22, presents methods of analysis and design of several important machine elements that were not pertinent to the design of the power transmission as presented in Part II. These chapters can be covered in any order or can be used as reference material for general design projects. Covered here are lain surface bearings; power screws and ball screws; fasteners; springs; machine frames, bolted connections, and welded joints; electric motors; and clutches and brakes.
Chapter 23 briefly outlines 30 design projects that instructors can select to give students practice in the application of their mechanical design skills.
