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.
