AGMA Fall Technical Meeting Papers Announced

Alexandria, VA, June 27, 2017 –The American Gear Manufacturers Association (AGMA) announces the twenty-five papers and three special presentations chosen for the Fall Technical Meeting being held October 22-24, 2017 at the Greater Columbus Convention Center, Columbus, Ohio. Twenty-eight presenters will speak in five sessions that include:


  • Session I – Efficiency, Lubrication, Noise, and Vibration
  • Session II – Manufacturing, Inspection, and Quality Control
  • Session III – Application, Design, and Rating
  • Session IV – Materials and Heat Treatment
  • Session V – Gear Wear and Failure 


The AGMA Technical Division Executive Committee (TDEC) chose the papers through a rigorous double-blind, peer review process. “The FTM is known for its focus on applications in our industry,” stated VP, Technical Division, Amir Aboutaleb. “This year, we had a very solid group of submitted work to choose from and will have a strong group of presenters.”


Complete information regarding papers and presenters, including abstracts, photos, and bios, is available on the AGMA website

Registration for the FTM is part of the Gear Expo registration that can be found at


The three special presentations include:

Indexing Error and Dynamic Factors of Spur Gears

According to ANSI/AGMA 2001-D04, dynamic factor is directly related to gear quality and pitch line velocity. This study uses a dynamic load distribution model in order to assess the validity of this relationship and investigate its physical source. Predictions of both gear root stress and contact stress dynamic factor are considered in the study.

The Link Between Steel Cleanness Measurement and Gear Life Performance

Several current industry material (cleanness) standards were reviewed and found to have poor correlation to gear fatigue performance. Possible reasons for the lack of correlation are discussed. Selected advanced cleanness measurement methods, and appropriate resulting metrics are offered as alternative, providing quantitative data in a format that may be used as tools for gear designers to improve gear reliability and highlight potential for light weighting and increased power.

Dr. Peter C. Glaws, TimkenSteel


Reverse Gear System Engineering − Why, When & How − (Avoiding Pitfalls…and Litigation!)

Reverse engineering a gear system is a not too unusual task, thus it is easy to become complacent. Failure to fully follow best practices can result in, in the worst cases, very expensive, time consuming, and reputation-damaging litigation. This presentation will rely on the experience of being an Expert Witness to provide information to aid the reverse engineering of a project as completely as possible.
