Direct Gear Design (Hardcover; 328 pp.; CRC Press) by Dr. Alex Kapelevich, is now available for online purchase—at both CRC Press ($129.95) and Amazon ($117.58). Direct Gear Design presents Kapelevich’s copyrighted, alternative “direct gear design” approach and compares it to traditional methods. It covers all theoretical and practical matters of advanced gear geometry and outlines various optimization techniques for custom gear drive performance maximization. It explains asymmetric gear design and its benefits for various applications and provides real-world examples of direct gear design implementation. Direct Gear Design includes information on macrogeometry of gear, tolerancing and tolerance analysis, gear measurement, gear fabrication technologies and tooling and much more. Kapelevich is a consultant at AKGears, LLC and a regular contributor to Gear Technology.
