Of all the many types of machine elements which exist today, gears are among the most commonly used. The basic idea of a wheel with teeth is extremely simple, and dates back several thousand years. It is obvious to any observer that one gear drives another by means of the meshing teeth, and to the person who has never studied gears, it might seem that no further explanation is required. It may therefore come as a surprise to discover the large quantity of geometric theory that exists on the subject of gears, and to find that there is probably no branch of mechanical engineering where theory and practice are more closely linked. Enormous improvements have been made in the performance of gears during the last two hundred years or so, and this has been due principally to the careful attention given to the shape of the teeth. The theoretical shape of the tooth profile used in most modern gears is an involute. When precision gears are cut by modern gear-cutting machines, the accuracy with which the actual teeth conform to their theoretical shape is quite remarkable, and far exceeds the accuracy which is attained in the manufacture of most other types of machine elements. The first part of this book deals with spur gears, which are gears with teeth that are parallel to the gear axis. The second part describes helical gears, whose teeth form helices about the gear axis.
Provides an up-to-date, single-source reference for all aspects of the gear industry Presents an integrated approach to gear design and manufacture Includes new coverage of direct gear design and ready-to-use gear design Contains coverage of finite element analysis, gear vibration, load ratings, and gear failures
Many clock repairers carry out excellent work but avoid cutting their own wheels and pinions, fearing it is too complicated and involved. This book, written by an experienced clock and tool maker, dispels those fears and gives a step-by-step guide to an extremely satisfying aspect of horology. This book is written for both the amateur and professional involved in the making and restoring of clocks, and for anyone who intends to start building up a workshop and requires a guide to the equipment and how to use it.
Over the last several decades, gearing development has focused on improvements in materials, manufacturing technology and tooling, thermal treatment, and coatings and lubricants. In contrast, gear design methods have remained frozen in time, as the vast majority of gears are designed with standard tooth proportions. This over-standardization signif
Over 2000 drawings make this sourcebook a gold mine of information for learning and innovating in mechanical design The fourth edition of this unique engineering reference book covers the past, present, and future of mechanisms and mechanical devices. Among the thousands of proven mechanisms illustrated and described are many suitable for recycling into new mechanical, electromechanical, or mechatronic products and systems. Overviews of robotics, rapid prototyping, MEMS, and nanotechnology will get you up-to-speed on these cutting-edge technologies. Easy-to-read tutorial chapters on the basics of mechanisms and motion control will introduce those subjects to you or refresh your knowledge of them.
