Book Description
The history of gears with asymmetric teeth is not sufficiently recorded in modern gear literature, with some gear researchers concluding that asymmetric tooth gears were discovered just several decades ago. This book sheds light upon the origins and state of asymmetric gearing, referencing technical articles from the 19th, 20th, and 21st centuries. As a practicing gear engineer with over 40 years’ experience, author Alexander L. Kapelevich has successfully implemented asymmetric gears in a variety of custom gear transmissions. This book addresses all aspects of asymmetric gear development, including theoretical fundamentals; tooth geometry optimization; stress analysis and rating; design and production specifics; analytical and experimental comparison to the best symmetric gears; and application examples. Readers are encouraged to look beyond the status quo established by traditional gear design, and to apply principles of asymmetric gearing to actual gear design. Optimal solutions are presented for gear drives that will maximize technical performance and marketability. Features Presents a state-of the-art, comprehensive historical overview of asymmetric gearing Explains the Direct Gear Design® approach to asymmetric gear design Describes asymmetric tooth gear geometry optimization, areas of existence, and parameter selection limits Considers practical aspects of asymmetric gear fabrication and measurement Presents analytical and experimental comparison of asymmetric gears to advanced symmetric gears, showing the advantages of asymmetric designs Provides numerous real-world examples of asymmetric gear application

Book Description
Updated throughout for the third edition, Theory of Gearing: Kinematics, Geometry, and Synthesis is an essential resource for engineers in the field of gearing. Detailing gear design, production, inspection, and application, the book covers cutting-edge gear types to enable the reader to fully keep track of modern gear developments. Demonstrating the rigorous scientific theory behind optimal gear design, manufacture, and performance, a key focus of the new edition is on aiding engineers in designing low noise transmissions in smaller sizes, improving fuel consumption and reducing emissions. Chapters included will discuss key features of Split-Power-Transmission-Systems (SPTS) with equal (almost equal) power share, and Uniform Rotary Motion. Entirely new chapters for the third edition include: Parallel-Axes involute gearing of specific design and gear, and Novikov/Conformal and High-Conformal gearing. The book will be of interest to engineers and researchers in the gearing industry. It will also have relevance to those working in tribology, metallurgy, and materials processing, alongside engineers working in precision manufacturing.

Book Description
Over the last several decades, gearing development has focused on improvements in materials, manufacturing technology and tooling, thermal treatment, and coatings and lubricants. In contrast, gear design methods have remained frozen in time, as the vast majority of gears are designed with standard tooth proportions. This over-standardization significantly limits the potential performance of custom gear drives, especially in demanding aerospace or automotive applications. Direct Gear Design introduces an alternate gear design approach to maximize gear drive performance in custom gear applications. Developed by the author, the Direct Gear Design® method has been successfully implemented in a wide variety of custom gear transmissions over the past 30 years. The results are maximized gear drive performance, increased transmission load capacity and efficiency, and reduced size and weight. This book explains the method clearly, making it easy to apply to actual gear design. Describes the origin and theoretical foundations of the Direct Gear Design approach as well as some of its applications—and its limits Details the optimization techniques and the specifics of Direct Gear Design Discusses how this approach can be used with asymmetric gears to further improve performance Describes tolerance selection, manufacturing technologies, and measurement methods of custom gears Compares Direct Gear Design with traditional gear design from both an analytical and an experimental perspective Illustrates the applicability and benefits of this gear design approach with implementation examples Written by an engineer for engineers, this book presents a unique alternative to traditional gear design. It inspires readers to explore ways of improving gear transmission performance in custom gear applications, from higher transmission load capacity, efficiency, and reliability to lower size, weight, and cost.

Book Description
Polymer Gears discusses polymer gear design and their efficient mechanical properties, light weight, and low noise during operation. As plastic gears are replacing metallic gears in traditional and new applications, there is still lack of material characterization and complex relations between different geometric and operating parameters. Thus, polymer gear design remains an open challenge. This book serves as a comprehensive and professional guide on the topic, providing readers with current developments carried out in the field of plastic gears production, characterization, and applications. This will include material development, tribological properties, simulations, and processing methods. - Current developments carried out in the field of plastic gear production - Presents the characterization of plastic gear production - Includes applications of plastic gear production and development - Provides updates on tribological properties, simulations, and processing methods
