Stretch Your Training Budget
Interested in getting more out of your training budget?  Want to implement a continuous training program without increasing your budget?  Interested in staying up-to-date with the latest trend in the gearing industry while rubbing elbows with some of the most experienced and knowledgeable minds in the industry?

If you answered yes to any of these questions, then you need to get involved with AGMA Technical committees.  Since its inception almost 100 years ago, AGMA has been helping the gear industry by developing technical standards and information sheets covering a wide variety of topics from design and manufacturing to testing and failure analysis.  In doing so, AGMA has always relied on the dedication and valuable contributions of the individuals from AGMA member companies that make up our technical committees. The individuals themselves have found their participation in the technical committees beneficial in more ways than one. Aside from the direct benefit gained through the application of developed standards and information sheets, they have found their involvement in the committees also beneficial in terms of the opportunities they are given to interact with, and learn from, their counterparts from around the industry. AGMA holds more than 100 technical committee meetings each year. Many of these are held virtually, using Web-Ex or other online meeting tools, making it easier for AGMA members from Europe, South America, India, and other parts of the world to attend and collaborate with their colleagues on various issues. Seats within the technical committees are not just for experts, AGMA welcomes those coming up the ranks to participate and grow into future experts on these committees.  

The following is a brief outline of current activities within some of the AGMA Technical Committees. For more information on these activities and or committee membership, contact Amir Aboutaleb at Aboutaleb@agma.org.

You can avoid gear failure and save thousands of dollars in repair costs! It’s all about knowing what causes gear failure and how to prevent it from occurring.

A gear failure analysis expert will use a variety of tools and methods – lectures, slide presentations, hands-on workshops with failed gears and Q&A sessions – to give you a comprehensive understanding of the reasons for gear failure. Participants are encouraged to bring their own failed gears or photographs and discuss them during the Q&A sessions.

The seminar brings together a vast amount of knowledge not available elsewhere. It will help you solve every day problems whether you are a gear engineer, user, researcher, maintenance technician, lubricant expert, or manager.
