Book Description
This revised, expanded, edition covers the theory, design, geometry and manufacture of all types of gears and gear drives. This is an invaluable reference for designers, theoreticians, students, and manufacturers. This edition includes advances in gear theory, gear manufacturing, and computer simulation. Among the new topics are: 1. New geometry for modified spur and helical gears, face-gear drives, and cycloidal pumps. 2. New design approaches for one stage planetary gear trains and spiral bevel gear drives. 3. An enhanced approach for stress analysis of gear drives with FEM. 4. New methods of grinding face gear drives, generating double crowned pinions, and improved helical gear shaving. 5. Broad application of simulation of meshing and TCA. 6. New theories on the simulation of meshing for multi-body systems, detection of cases wherein the contact line on generating surfaces may have its own envelope, and detection and avoidance of singularities of generated surfaces.

Book Description
This book presents the latest accomplishments in Novikov/conformal gearing as well as high-conformal gearing. It is focused primarily on strength calculation of gear teeth and the manufacturing of gears for Novikov/conformal and high-conformal gearing along with a brief discussion of achievements in the modern theory of gearing. The modern theory of gearing is the foundation of all optimal designs of gears, gear-sets, and transmissions of all known designs, as well as, of all those to be developed in the future. As even a small improvement in efficiency on a single gear can represent a significant cost saving, given the millions of gears used in industry every year, this volume provides the design and manufacturing engineer in invaluable resource.

Book Description
This book presents recent developments in the theory of gearing and the modifications in gear geometry necessary to improve the conditions of meshing. Highlighted are low-noise gear drives that have a stable contact during meshing and a predesigned parabolic transmission error function that can handle misalignment during operation without sacrificing the low-noise aspects of operation. This book also provides a comprehensive history of the develoment of the theory of gearing through biographies of major contributors to this field. The author's unique historical perspective was achieved by assiduous research into the lives of courageous, talented, and creative men who made significant contributions to the field of gearing.

Book Description
Modern Gear Production focuses on the processes and methods in gear making. The book first gives information on the history of gear making and types of gears. Topics such as the classification of gears based on the disposition of their shafts; shafts lying in the same plane with axes intersecting; and shafts lying in parallel planes but with axes inclined to one another are then discussed. The text describes gear groups, tooth forms, and gear materials. Heat treatment of steels, casehardening, nitriding, induction hardening, sulfinuzing, and flame hardening are explained. The book takes a look at blank manufacture, gear milling, and gear shaping and planning. The text further examines gear hobbing. Topics include precision of hobbing machines, worm-wheel hobbing, hob setting, control of accuracy of gears, and hobbing gears for general purposes. The different kinds of hobs, profile grinding, and shaving and lapping are also discussed. The book also focuses on other manufacturing methods, such as thread whirling, broaching gear teeth, tooth rounding, work hardening, and electrochemical machining. The text is a vital source of data for readers interested in gear making.

Book Description
The new edition of High-Conformal Gearing continues to address the kinematics and the geometry of conformal (Novikov) gearing and high-conformal gearing. The book deals with gears that feature convex-to-concave contact of the tooth flanks of a gear and a mating pinion. Gears of this type are commonly referred to as conformal gearings. Novikov gearing is the most widely known example of conformal gearing. The helical gearing by Wildhaber, Bramley-Moore (otherwise known as the Vivkers, Bostock, and Bramley gearing, or just V.B.B.-gearing), are well-known designs of gearing that are loosely referred to as conformal gearing. The principal differences between conformal gearing as well as high-conformal gearing and Wildhaber helical gearing are outlined. It also shows that Wildhaber helical gearing from one side, and Novikov gearing from another side, are two completely different gear systems that cannot be combined into a common gear system. This book aids mechanical, automotive, and robotics engineers specializing in gear design with successfully transmitting a rotation. It also serves as a resource for graduate students taking advanced courses in gear design. Discusses the kinematics and geometry of conformal and high-conformal gearing Provides a specific set of conditions which need to be met when designing conformal and high-conformal gears Outlines the principal differences between conformal, high-conformal and Wildhaber helical gearing
