Noncircular Gears - Fuentes-Aznar, Alfonso

. .

Résumé :
Noncircular Gears: Design and Generation represents the extension of the modern theory of gearing applied to the design and manufacture of the main types of noncircular gears: conventional and modified elliptical gears, eccentric gears, oval gears, gears with lobes, and twisted gears. This book is enhanced by updated theoretical description of the methods of generation of noncircular gears by enveloping methods similar to those applied to the generation of circular gears. Noncircular Gears: Design and Generation also offers new developments directed to extend the application of noncircular gears for output speed variation and generation of functions. Numerous numerical examples show the application of the developed theory. This book aims to extend the application of noncircular gear drives in mechanisms and industry....

Biographie:
Faydor L. Litvin has been a Professor at the University of Illinois, Chicago for the past 30 years after 30 years as a Professor and Department Head of Leningrad Polytechnic University and Leningrad Institute of Precise Mechanics and Optics. Dr Litvin is the author of more than 300 publications (including 10 monographs) as well as the inventor and co-inventor of 25 inventions. Among his many honors Dr Litvin was made Doctor Honoris Causa of Miskolc University, Hungary, in 1999. He was named Inventor of the Year 2001 by the University of Illinois at Chicago and has been awarded 12 NASA Tech Brief awards; the 2001 Thomas Bernard Hall Prize (Institution of Mechanical Engineers, UK); and the 2004 Thomas A. Edison Award (ASME). He was elected a Fellow in the ASME and American Gear Manufacturers Association (AGMA). He has supervised 84 Ph.D. students. In addition to his deep interest in teaching, Dr Litvin has conducted seminal research on the theory of mechanisms and the theory and design of gears.
