A Gear Chronology


Book Description

A Gear Chronology A Review In his foreword to A Gear Chronology book, author William P. Crosher dedicates his work to “those engineers and organizations that give freely of their time and experience to develop standards and technical conferences that are so crucial to the progress of the gear industry.” In my experience, Crosher demonstrates this same desire to know all he can about his profession, and to contribute to its continued growth and evolution in an ongoing and proactive manner. As complicated and technical as some of the topics he discusses can be, Crosher writes in a manner that is straightforward, accessible, and informative. In other words, he harnesses the same approach utilized by any good teacher in finding a way to engage his audience while at the same time conveying valuable information. He achieves this by providing historical and peripheral material that brings the subject under discussion to life. In chapters devoted to the fundamentals of gearing, definitions of gear elements, materials, and processes such as heat treating, the author builds a solid foundation for later chapters on subjects including spur, helical, and worm gear design, gear manufacturing and inspection, lubrication properties, and failure modes, along with an analysis of those examined. Topics are explored fully and explained clearly, with a wealth of helpful illustrations in support of the text. References and resources are listed at the end of the book, including contact information for associations that can assist in the reader’s continued professional growth. The former director of the National Conference on Power Transmission, as well as former chairman of the American Gear Manufacturers Association’s Marketing Council and Enclosed Drive Committee, Crosher was resident engineer-North America for Thyssen Gear Works, and later at Flender Graffenstaden. He is author of the book Design and Application of the Worm Gear and longtime writer of the “Tooth Tips” column that appears each month in the pages of Gear Solutions magazine, which is published by Media Solutions, Inc. As editor I can attest to the fact that his work generates a high degree of reader response, and that he is both known and respected in the gear-manufacturing industry around the world. It is an honor to be in a position to share his knowledge and expertise with our readers, and to have the opportunity to comment on his latest professional endeavor.

Gears of War: The Slab


Book Description

"Based on the Xbox 360 video game series from Epic Games/Microsoft Game Studios."




Advances in Gear Design and Manufacture


Book Description

Advances in Gear Design and Manufacture deals with gears, gear transmissions, and advanced methods of gear production.The book is focused on discussion of the latest discoveries and accomplishments in gear design and production, with chapters written by international experts in the field. Topics are aligned to meet the requirements of the modern scientific theory of gearing, providing readers precise knowledge and recommendations on how perfect gears and gear transmissions can be designed and produced, and how they work. It explains how gears and gear transmissions can be designed to reach high a “power-to-weight” ratio, and how to design and produce compact, high-capacity gearboxes.




History of Technology Volume 7


Book Description

The technical problems confronting different societies and periods, and the measures taken to solve them form the concern of this annual collection of essays. Volumes contain technical articles ranging widely in subject, time and region, as well as general papers on the history of technology. In addition to dealing with the history of technical discovery and change, History of Technology also explores the relations of technology to other aspects of life -- social, cultural and economic -- and shows how technological development has shaped, and been shaped by, the society in which it occurred.




Gears


Book Description

This book provides a compact history of gears, by summarizing the main stages of their development and the corresponding gradual acquisition of engineering expertise, from the antiquity to the Renaissance and the twentieth century. This brief history makes no claim to be exhaustive, since the topic is so extensive, complex and fascinating that it deserves an entire encyclopedia. Despite its brevity, the book debunks a number of popular misconceptions, such as the belief that the first literary description of a gear was supplied by Aristotle. It disproves not only this myth, but also other peremptory statements and/or axiomatic assumptions that have no basis in written documents, archaeological findings or other factual evidence. The book is chiefly intended for students and lecturers, historians of science and scientists, and all those who want to learn about the genesis and evolution of this topic.







Minerva Meets Vulcan: Scientific and Technological Literature – 1450–1750


Book Description

This book offers a comprehensive study and account of the co-evolution of technological and scientific literature in the early modern period (1450-1750). It examines the various relationships of these literatures in six areas of knowledge – Architecture, Chemistry, Gunnery, Mechanical Engineering, Mining, and Practical Mathematics – which represent the main types of advanced technological and scientific knowledge of the era. These six fields of technologically advanced knowledge and their interrelations and interactions with learned knowledge are investigated and discussed through a specific lens: by focusing on the technological literature. Among present-day historians of science, it hardly remains controversial that contact and exchange between educated and practical knowledge played a significant role in the development of the natural sciences and technology in early modern Europe. Several paths for such exchange arose from the late Middle Ages onward due to the formation of an economy of knowledge that fostered contacts and exchange between the two worlds. How can this development be adequately described and how, on the basis of such a description, can the significance of this process for the early modern history of knowledge in the West be assessed? These are the overarching questions this book tries to answer. There exists a considerable amount of literature concerning several stations and events in the course of this long development process as well as its various aspects. As meritorious and indispensable as many of these studies are, none of them tried to portray this process as a whole with its most essential branches. What is more, many of them implicitly or explicitly took physics as a model of science, and thus highlighted mechanics and mechanical engineering as the model of all interrelations of practical and learned knowledge. By contrast, this book aims at a more complete portrait of the early modern interrelations and interactions between learned and practical knowledge. It tries to convey a new idea of the variety and disunity of these relations by discussing and comparing altogether six widely different fields of knowledge and practice. The targeted audience of this book is first of all the historians of science and technology. As one of the peer reviewers suggested – the book could very well become a textbook used for teaching the history of science and technology at universities. Furthermore, since the book addresses fundamental aspects of the significance emergence and development of modern science has for the self-image of the West, it can be expected that it will attract the attention and interest of a wider readership than professional historians.
