The American Gear Manufacturers Association (AGMA) Technical Division is pleased to announce the publication of AGMA 916-A19, Face Gears with Intersecting Perpendicular Axes information sheet.

Pages: 93 | Member Price: $95.00 | Nonmember Price: $190.00 (Note that members can access a free download until 3/19/2020) 

This information sheet describes design calculations for spur pinions and face gears that intersect with perpendicular axes. The procedure described in this document will result in a face gear tooth geometry that is defined by the generating action of a reciprocating spur gear cutter which incorporates certain essential features of the mating pinion. The method described applies to all modules and profile angles.

This document describes design calculations for spur pinions and face gears that intersect with perpendicular axes. Face gears can also be designed in non-right-angled arrangements, helical arrangements or offset axis configurations. These methods go beyond the scope of this document.

The procedure described in this document will result in a face gear tooth geometry that is defined by the generating action of a reciprocating spur gear cutter which incorporates certain essential features of the mating pinion.

The manufacturing approach described by this procedure is outlined in Clause 4.

This information sheet is dedicated to Irving Laskin. His participation and inspiration led to the development of this information sheet. His thoroughness, contributions of his time, and enthusiasm for gearing, along with the contributions of his fellow committee members were instrumental in the creation of this document.

Prior to the first publication of AGMA 916-A19, AGMA’s technical library included a withdrawn document AGMA 203.03 (1973), Fine Pitch on-Center Face Gears for 20 Degree Involute Spur Pinions. AGMA 916-A19 is a complete rewrite of the former document and now encompasses all modules and profile angles. At the same time, it eliminates all of the graphical calculation methods previously used and replaces them with computational methods. A more detailed explanation of the design and manufacturing is provided.

The first draft of AGMA 916-A19 was made in March 1996. It was approved by the AGMA membership in June 2019.
