DSGN07098 2019 Machine Design
The aim of this module is to introduce the learner to the design and selection of key mechanical engineering components as used in machines. The module will provide an overview of the design process for a machine. It will examine the design and selection of mechanical engineering elements such as bearings, shafts, gears, belts, chains and clutches. Finally, the module will examine CE marking and the Machinery Directive, which is central to machinery design, construction, integration and marketing.
On completion of this module the learner will/should be able to;
Use the engineering design process to develop design specifications.
Select and analyse mechanical engineering components such as bearings, gears, belts, chains, brakes and clutches, seals and gaskets.
Evaluate deflections and critical speeds of shafts.
Demonstrate competence in the application of aspects of the CE marking process.

2013-09-24 Mechanical Design Engineering Handbook Butterworth Heinemann
ISBN 0080977596 ISBN-13 9780080977591
Mechanical Design Engineering Handbook is a straight-talking and forward-thinking reference covering the design, specification, selection, use and integration of machine elements fundamental to a wide range of engineering applications. Develop or refresh your mechanical design skills in the areas of bearings, shafts, gears, seals, belts and chains, clutches and brakes, springs, fasteners, pneumatics and hydraulics, amongst other core mechanical elements, and dip in for principles, data and calculations as needed to inform and evaluate your on-the-job decisions. Covering the full spectrum of common mechanical and machine components that act as building blocks in the design of mechanical devices, Mechanical Design Engineering Handbook also includes worked design scenarios and essential background on design methodology to help you get started with a problem and repeat selection processes with successful results time and time again. This practical handbook will make an ideal shelf reference for those working in mechanical design across a variety of industries and a valuable learning resource for advanced students undertaking engineering design modules and projects as part of broader mechanical, aerospace, automotive and manufacturing programs. Clear, concise text explains key component technology, with step-by-step procedures, fully worked design scenarios, component images and cross-sectional line drawings all incorporated for ease of understanding. Provides essential data, equations and interactive ancillaries, including calculation spreadsheets, to inform decision making, design evaluation and incorporation of components into overall designs. Design procedures and methods covered include references to national and international standards where appropriate.

ISBN 0134441184 ISBN-13 9780134441184
The concepts, procedures, data, and analysis techniques needed to design and integrate machine elements into mechanical devices and systems. For over three decades students and practicing engineers have used Machine Elements in Mechanical Design to learn about the principles and practices of mechanical design. They have either continued to use the text in their careers, or have newly discovered it as an invaluable resource in their work. With an emphasis on applying the technology of various machine elements while considering those elements in the context of the larger machine, this text references a broad array of available resources, from industrial sources to professional organizations. It promotes practical decision making in design and provides excellent preparation for moving from an academic environment to a professional position with strong, long-term growth potential. Continuing the book's emphasis on proven approaches and the use of readily available materials, and its focus on practical, safe, and efficient design, this edition includes new content and adjustments contributed by the two new coauthors and features stronger technical content in stress analysis, a wider set of technical topics, and beautiful enhancements to the visual attractiveness of the book throughout numerous new full-color graphic illustrations. Appreciated for its readability, while recognized for its technical strength and comprehensive coverage of the material, Machine Elements in Mechanical Design is the ideal guide to the skills and knowledge needed for success in this field.
