High Profile Contact Ratio Gearing - August 27, 2020Includes Credits
High Profile Contact Ratio (HCR) gears, both spur and helical, have been shown to provide significant reductions in gear mesh frequency noise and vibration levels and, depending on the specific configuration, improved load capacity as well. The design of HCR gears is, however, far from a simple task and must be carefully accomplished. In addition, HCR gears are not appropriate for every circumstance. In this seminar we will learn just what HCR gears are and under what circumstances they can be used to advantage. Similarly, we will learn when HCR gears are not appropriate and why. We will cover the detailed tooth geometry changes that are required to effectively achieve optimum performance and benefit. We will learn how the load distribution along the involute profile changes when the contact ratio increases above two. Because of the longer, generally more slender teeth on a HCR gear the heat treatment and profile modifications that are required for good performance are distinctly different from those for a standard contact ratio gear. The load capacity rating of HCR gears requires the application of modified AGMA analyses as the AGMA Standards specifically do NOT address gears with profile contact ratios greater than 2.0 thus we will also cover the changes required to successfully rate HCR gears.
Who Should Attend:
Engineers looking to get a better understanding of high contact ratio gearing and when it makes sense for application.
Expected Student Learning (Course Level) Outcomes:
- 1. Identify what a HCR gear is and understand when to use them
- 2. Recognize the detailed tooth geometry requirements to achieve optimum gear performance
- 3. Classify the changes required to successfully rate HCR gears
External Spur And Helical Gear Mesh Contact Analysis Video TrainingIncludes Credits
This online seminar will calculate and demonstrate the effect that shaft bending, torsional windup and tooth deflections have on loaded tooth contact on various configurations of parallel shaft spur and helical gearing. With the loaded tooth and shaft deflections identified in real life examples, tooth helix and profile modifications will be developed that, when properly manufactured and applied, will significantly improve loaded tooth mesh contact to support realistic load distribution factors used in rating of parallel shaft spur and helical gears. The process involves the application of commercially available software that models the loaded gear mesh in FEA. This evaluation and corrective action will promote optimization of power density with predictable fatigue life.
Who Should Attend:
Engineers looking to get a better understanding of gear mesh contact analysis
Expected Student Learning (Course Level) Outcomes:
1. Discuss and review how loaded tooth and shaft deflections impact tooth mesh contact.
2. Learn how to apply commercially available tooth mesh FEA software to model and calculate predicted load distribution factor Km for a gear drive.
3. Determine corrective helix and profile modifications to counter act tooth deflections, improve Km and optimize power density of modeled gear drives

Terry graduated with a BS-Engineering in 1976 and a MS-Engineering from UW-Milwaukee in 1981 and enjoys sharing his knowledge and passion for gears through formal consulting and training activities.
Gear Failure Analysis Online Video CourseIncludes Credits
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.
Through generous support from the AGMA Foundation, AGMA has recorded the popular Gear Failure Analysis live course for wider availability.
Robert Errichello heads his own gear consulting firm, GEARTECH, and is founder of GEARTECH Software, Inc. He is a registered Professional Engineer who holds BS and MS degrees in Mechanical Engineering and a Master of Engineering degree in structural dynamics from the University of California at Berkeley. Mr. Errichello helped to introduce the world’s first gearing standard for wind turbines and is very active in AGMA standards development and nomenclature. He has extensive teaching experience and has taught college courses on machine design, fracture mechanics, vibration, and material science. He has over 40 years of industrial experience, is author of more than 60 articles on design, analysis, and application of gears, and has written three widely-used computer programs for the design and analysis of gears. Mr. Errichello is a recipient of AGMA’s prestigious Lifetime Achievement Award and an expert in Failure Analysis.
