Dudley's handbook of practical gear design and manufacture (2^nd Ed.)

For more than 30 years, the book Practical Gear Design, later re-titled the Handbook of Practical Gear Design, has been the leading engineering guide and reference on the subject. Now available again in this revised edition, the book is a detailed, practical guide and reference to gear technology. It covers the design of all types of gears, from those for small mechanisms to large industrial applications. The presentation is designed for easy reference for those involved in practical gear design, manufacture, applications, and problem solving. The text is well-illustrated with clear diagrams and photographs. The many tables provide needed reference data in convenient form.
