scope:

Face gear technology has attracted attention. Products benefiting include those which use molded plastic gears. More applications could benefit, justifying the need formore information on the special features of face gears, their design and manufacture, in comparison to other non--parallel--shaft gears. A description of manufacturing methods, particularly in plastic molding is given with inter--related design and gear performance issues. New methods of graphic modeling are included with descriptions of face gear configurations and applications.
