Litvin F.L. Development of Gear Technology and Theory of Gearing.
На английском языке. О зубчатых передачах, технология и теория.
First published in 1997 by National Aeronautics and Space Administration in
Washington DC . Written in English, 120 pages.
A NASA Reference Publication discusses gear technology from mathematical and historical perspectives. Following a preface containing historical and philosophical observations, the first of three chapters presents mathematical details of the theory of gearing, including recent developments attributable to the author and others. The second chapter discusses the development of gear geometry and technology, with emphasis on modifications of gear geometries to improve conditions of meshing. The third chapter presents biographies of inventors, scientists, and founders of gear companies in order to credit the contributions made by previous innovators and to combine the separate pieces of the history of gear technology and the theory of gearing.
