Gear Failure Analysis

June 24–26—AGMA National Training Center; Chicago

Explore gear failure analysis in this hands-on seminar where students not only see slides of failed gears but can hold and examine over 130 specimens with the same failure modes covered in the seminar. Approximately half of the course time consists of students in groups identifying failure modes on failed gears and working on a case study. Microscopes are available to examine failed specimens.

How to Read and Interpret a Gear Inspection Chart

July 16—Live Online Course

This half-day online seminar is intended to provide you with a thorough understanding of the information contained within a typical gear inspection report. Specifically, we will look at the contents and meaning of the information contained within the gear charts, as well as the techniques used by the gear measurement system to assess gear quality. An explanation of basic gear measurement techniques, how measurement equipment and test machines implement these techniques, and how to interpret the results from these basic measurements will be covered. We will also discuss how to interpret the results and what corrective actions may be considered if the quality of a particular gear is unsatisfactory.

Loaded Tooth Contact Analysis

August 5—Live online Course

This course explores using commercially available software to evaluate loaded tooth contact and develop tooth modifications that improve load distribution and reduce transmission error in gear systems. Through two real-life examples and supporting optimization techniques—including LTCA, material and heat treatment selection, profile shift, isotropic finishing, shot peening, and precision improvements—participants will learn how to enhance gear design reliability and calculated safety factors.

EV Automotive Transmission Development

August 19–21—DoubleTree by Hilton O’Hare; Rosemont, IL

This course explores the complete process of EV transaxle gearbox development—from concept and design to early-stage analysis—focusing on common architectures, power flow, and functional requirements. A key emphasis will be on how the absence of an internal combustion engine in electric vehicles changes NVH (noise, vibration, and harshness) dynamics, necessitating quieter, more precisely designed gearboxes to accommodate the unique frequency and vibration profiles of electric motors.

NASA's Top 5 Technical Challenges Countdown: #5: High-Powered Robotics

Universe Today

To make more impressive robots, designers have focused on increasing the power density: the amount of energy that robots can store and send through their various parts and systems. The more power you have available to all these systems, the more you can do. It's not just about having a big battery pack or solar cell. We need the ability to get this power to a robot's subsystems. We need more powerful electric motors, gearing, and drivetrain components.
