Annex A is a bibliography.
The information in this manual is meant to serve only as a guide to the designer of fine-pitch gears. It is not intended that it be the procedure which must be followed in the design of such gears, nor is it implied that using the procedures and data will necessarily result in gears that will meet the requirements in every application. It remains the responsibility of the individual designer to properly evaluate the conditions in the particular application and to make use of prior experience or proper testing to confirm the suitability of the design.
TOOTH FORM (SPUR AND HELICAL GEARING, INTERNAL AND EXTERNAL)
The tooth form of the spur and helical gearing considered in this manual is involute. Unless specifically noted, all external spur and helical designs resulting from the procedures discussed in this manual will be conjugate with standard basic racks. See ANSI/AGMA 1003-G93.

Although there is a great deal of information about parallel shaft fine-pitch gearing in the literature, it is widely scattered and a considerable number of areas are not well covered. As a result, this manual has been compiled to provide a central source of the best information available on the design, manufacture and inspection of fine-pitch gearing.
This manual is a revision of 370.01, Design Manual for Fine Pitch Gearing, 1973. Additions have been made to the design section to broaden the concepts of gear theory and the gear design process. Omitted from this Manual are wormgears, bevel gearing and face gearing which appeared in the original design manual. This information is available in other AGMA Standards.
An important feature of this manual is the bibliography to which the user is referred for additional data in each area.
Suggestions for improvement of this standard will be welcome. They should be sent to the American Gear Manufacturers Association, 1001 N. Fairfax Street, Suite 500, Alexandria, Virginia 22314.
