Machine Elements in Mechanical Design 6th Edition Pdf Book Description:
Working with the latest up-to-date info, this publication gives a practical method of designing machine components in the context of total mechanical design. Covering a number of the principal machine components like belt drives, chain drives, gears, shafts, keys, couplings, seals, and rolling contact bearings. Additionally, it covers plain surface bearings, linear movement components, attachments, springs, machine frames, bolted connections, welded joints, electrical motors, controls, clutches, and also brakes. This novel is for any person layout specialist for which a sensible way of mechanical design, according to solid engineering principles, is wanted. The practical approach to designing machine elements in the context of complete mechanical designs is retained and refined in this edition. An extensive amount of updating has been accomplished through the inclusion of new photographs of commercially available machine components, new design data for some elements, new or revised standards, new end-of-chapter references, listings of Internet sites, and some completely new elements. Full color has been used for the first time to enhance the visual attractiveness of the book and to highlight prominent features of charts, graphs, and technical illustrations. Numerous, highly detailed, full-color new drawings have been added or have replaced drawings used in previous editions.
The design of machine elements inherently involves extensive procedures, complex calculations, and many design decisions. Data must be found from numerous charts and tables. Furthermore, design is typically iterative, requiring the designer to try several options for any given element, leading to the repetition of design calculations with new data or new design decisions. This is especially true for complete mechanical devices containing several components as the interfaces between components are considered. Changes to one component often require changes to mating elements. Use of spreadsheets, computational software, and computer-aided mechanical design software can facilitate the design process by performing many of the tasks while leaving the major design decisions to the creativity and judgment of the designer or engineer. We emphasize that users of computer software must have a solid understanding of the principles of design and stress analysis to ensure that design decisions are based on reliable foundations. We recommend that the software be used only after mastering a given design methodology by careful study and using manual techniques. The strong movement in the United States and other industrialized countries toward global sourcing of materials and products and the use of multinational design teams makes the use of commercial software highly valuable during the lifelong career of designers and engineers. Furthermore, the specification of commercially available machine components and systems typically involves the use of manufacturers’ software built into company Internet sites. This book provides guidance on the use of such sites as an integral part of the machinery design process.
