Heat Treatment of Gears


Book Description

Annotation Rakhit wants other engineers to avoid the considerable trouble he had understanding the art of gear heat treatment when he first embarked on a career in gear design and manufacturing. He explains how heat treating and gears made of some kinds of steel gives the gears high geometric accuracy, but can also distort them and raise the cost of manufacturing, so a gear engineer needs to excel in manufacturing, lubrication, life and failure analysis, and machine design as well as design. He presents a case history of each successful gear heat treatment process that provide information on the quality of gear that can be expected with the proper control of material and processes.

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


Book Description

This book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. This is the most advanced reference guide to the state of the art in gear engineering. Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined. The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

Gear Cutting Tools


Book Description

This book presents the DG/K-based method of surface generation, a novel and practical mathematical method for designing gear cutting tools with optimal parameters. The author, an industry leader for the past 30 years, proposes a scientific classification for all possible kinds of the gear machining meshes before discussing optimal designs of gear cutting tools. This classification makes it possible to consider all possible designs of gear cutting tools, including those currently used in practice and those expected to be used in the future. It also allows the author to develop scientific predictions and optimal designs. In most cases, solutions appear in analytical form and/or graphical form.

Book Description

The updated and improved second edition of Direct Gear Design details a nonstandard gear design approach that makes it possible to significantly improve gear drive performance. Providing engineers with gear design solutions beyond standard limits, this book delivers engineers with practical and innovative solutions to optimize gearing technologies. The majority of modern gears are over-standardized, not allowing gear design engineers to see possible gear design solutions outside of standard limits. The book explores opportunities to improve and optimize gears beyond these limitations. The method of Direct Gear Design has been proven to maximise gear drive performance, increase transmission load capacity and efficiency, and reduce size and weight. Discussing the use of gears made from powder metal and plastic, the book surveys gear manufacture and makes use of extensive references to encourage further exploration of gear design innovation. Additionally, the book provides an overview of manufacturing technologies and traditional gear design, as well as covering topics such as asymmetric gears, tolerance selection and measurement methods of custom gears. Written accessibly, with a focus on practical examples, this fully updated edition will serve as a guidebook for all professionals exploring high-performance gearing system technologies.
