Educating New Workers

The Foundation offers college scholarships to engineering students whose programs focus on gear technology and gear research. The guidelines and application are available at www.agmafoundation.org.

The Foundation links students to gear companies that offer internship opportunities. Contact us to have your company name added to the list.

The Foundation underwrote the development of a self-paced series of training modules (Fundamentals of Gearing, Gear Inspection, and Hobbing) that have provided more than 2,000 new and mid-level employees with an overview of gearing terminology and practices.

Training Engineers on Advanced Topics
The Foundation granted assistance to AGMA to develop curricula for two popular live courses: Detailed Gear Design: Beyond Simple Service Factors and Gearbox CSI: Forensic Analysis of Gear & Bearing Failures. The courses have trained more than 600 people over the past ten years.

Video-Based Courses Available Online Anytime
Grants from the Foundation created web-based versions of two popular courses: Gear Failure Analysis and Detailed Gear Design. In addition to taking the travel load off trainees, the web-based versions of these courses preserve the presentations by instructors Bob Erichello and Ray Drago for the future. 62 people have completed the trainings since they debuted in 2011 and 2012.

Published Book on Diagnosing Manufacturing Errors and Ghost Tones
A grant from the Foundation allowed the documentation of gear noise research and how-to’s for diagnosing errors and measuring deviations. The book, titled Performance-Based Gear Metrology, by William D. Mark, Ph.D, is for anyone interested in understanding how gear manufacturing errors and tooth damage cause transmission-error vibrations and noise.

Scientific Research to Advance the Industry
A Foundation-funded contaminated lubricants study at Columbia University is examining the influence of particle contaminants in order to propose solutions that save costs and extend gear life. Another Foundation-funded study at Ohio State University is developing models and contact patterns that predict micropitting.

Important work for the industry will continue thanks to your support. Please pledge to the Annual Campaign at www.agmafoundation.org.

AGMA Continuing Education Classes
AGMA has education classes throughout the country every the year, and staff has the opportunity to talk with a great many students. The students appreciate advanced training in gears, as many degreed engineers had only two or three weeks of gear training in school. Most learn on the job—in company training courses or from organizations like AGMA.

Over the past eight years, AGMA has steadily added to its advanced gear engineering course offerings to create the AGMA Advanced Gear Engineering Academy. In that time, more than 1,600 individuals participated in these courses, with some completing at least five of the seven courses offered. For these dedicated individuals, taking the Academy’s classes represents more than 100 classroom hours. It is quite an achievement and demonstrates real passion for continuing education in the gear industry. AGMA and the AGMA Education Advisory Council are pleased to recognize those who have accomplished this with an AGMA Advanced Gear Engineering Certificate.

The seven AGMA Advanced Gear Engineering Academy courses cover a large body of knowledge in gearing:

Gear Failure Analysis has been presented by gear failure analysis expert, Robert Errichello, for the last 20 years to sold-out sessions. The seminar brings together a vast amount of knowledge not available elsewhere to help solve everyday problems for a gear engineer, user, researcher, maintenance technician, lubricant expert, or manager.

Gear engineering expert Ray Drago presents Detailed Gear Design. This course, for advanced students with a good understanding of basic gear theory and nomenclature, covers all the factors going into good design from life cycle, load torque, and evaluating consequences.

Gear Manufacturing & Inspection, with Ray Drago, aims to narrow the information gap by providing gear design engineers with a good foundation in both manufacturing and inspection processes and procedures.

Gearbox System Design, with instructors Ray Drago and Steve Cymbala, addresses everything but the gears and bearings. It includes seals, lubrication, lubricants, housing, breathers, and other very important but less-mentioned details.

Gear Materials & Metallurgy, with instructors Ray Drago and Roy Cunningham, demonstrates how the gear design engineer and the gear metallurgist can work together to optimize the gear manufacturing process.

Gearbox CSI, with instructors Ray Drago and Joe Lenski, helps gear designers gain a better understanding of various types of gears and bearings. Students learn about the limitation and capabilities of rolling element bearings and the gears that they support so they can properly apply the best gear-bearing combination to any gearbox, whether simple or complex.

Bevel Gear System Design: Manufacture, Heat Treatment, Inspection & Application is presented by instructor Ray Drago and is a first-time offering for 2014. This practical approach for the Design Engineer pinpoints its focus specifically to bevel gears. This seminar addresses every aspect of the design and application of bevel gear systems.

Lineup Announced for the 2014 Fall Technical Meeting
The AGMA 2014 Fall Technical Meeting (FTM) provides an outstanding opportunity for you to receive the latest research in the field, network with your peers, and learn about latest methods and cutting edge technologies in the gearing industry today. This year’s FTM will be held October 12-14 at the Westin Crystal City just outside of Washington, DC.

The 2014 papers have been organized around the session topics of manufacturing and inspection, design calculations, gear drive components, gear drive design and application, and gear design. A preliminary list of papers is included below, and more details can be found on the AGMA website, www.agma.org.

These presentations are all about recent application-based research in the gear industry. Unlike many technical conferences where you have to choose which papers you want to hear, the FTM is designed for you to be able to hear all the presentations and take home practical information that may ultimately affect your company’s bottom line. 2014 FTM Sessions Include:
