Online Video Courses

Gear Failure Analysis, Detailed Gear Design, and Gearbox CSI: Gears Only are intended to provide an experience that closely resembles the courses that are offered in the Face-to-Face format. You will have 60 days to complete the course, pass the course assessment, and receive your certificate.

  • Gear Failure Analysis Online Video Course

     2 credits offered

    In the Gear Failure Analysis online video training, you will examine the various types of gear failure, such as overload, bending fatigue, Hertzian fatigue, wear, scuffing and cracking. Possible causes of these failures will be presented, along with some suggested ways to avoid them. 2.0 CEUs

    Taught by expert gear failure analyst, Robert Errichello, P.E., of GEARTECH, students get the experience of the course through 11 segments consisting of a total of 10 hours of in-depth discussion of gear failure modes and supporting training documents. Gear Failure Analysis teaches students the causes of gear failure and how to prevent it from occurring. Avoiding gear failure can save thousands of dollars in repair costs!

    In AGMAs Gear Failure Analysis online video training, you will examine the various types of gear failure, such as overload, bending fatigue, Hertzian fatigue, wear, scuffing and cracking. Possible causes of these failures will be presented, along with some suggested ways to avoid them.

    Bob Errichello uses a variety of tools and methods lectures, slide presentations and Q&A sessions to give you a comprehensive understanding of the reasons for gear failure. The video presents a vast amount of knowledge not available elsewhere and is presented in a clear, well organized and easily understood manner.
