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.
Dr. Alexander L. Kapelevich is a gear design consultant at AKGears, LLC. He holds a master’s degree in mechanical engineering at Moscow Aviation Institute and a Ph.D. degree in mechanical engineering at Moscow State Technical University. Dr. Kapelevich has more than 30 years of custom gear transmission research and design experience. He began his career working in the Russian aviation industry, where he was involved in R&D, software development, testing, and failure investigation for aerospace gear transmissions. Living in the United States since 1994, he developed the Direct Gear Design® methodology for custom gear transmissions that have been implemented in various fields, such as aerospace, automotive, agriculture, defense, robotics, racing, and many others. His specialties are the gear drive architecture, planetary systems, gear tooth macrogeometry optimization, gears with asymmetric teeth, and gear transmission performance maximization. Dr. Kapelevich is a member of American Gear Manufacturers Association.
