AGMA 916-A19 pdf free.AGMA Information Sheet Face Gears with Intersecting Perpendicular Axes.
The design analysis procedures described in this document are general enough to be applied to any set of pinion and face gear proportions provided that the proportions of the pinion are defined by a straight sided basic rack either with a sharp or circular arc fillet.
In applying this procedure, the generating action of the face gear cutter may result in a sweep condition that may remove functional material from the generated face gear tooth surface. As a result, this procedure is only recommended for designs with,
— pinions with 8 or more teeth;
— a gear ratio of at least 1.5:1;
— a system module of at least 0.2 mm.
Users of this information sheet must be aware that even within these limits, the resulting design needs to be verified for functionality.
The information in this manual is meant to serve only as a guide to the designer of face gear drives, 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 requirement in every application, It remains the responsibility of the designer to properly evaluate conditions in a specific application and to make use of prior experience or proper testing to confirm the suitability of the design.
