Designed for engineers and scientists in the rolling element bearing, gear, and power transmission industries who desire a more fundamental knowledge of component-relevant topics in the lubrication and wear areas within the field of tribology. The science behind lubrication and wear continues to evolve. This course introduces attendees to important terminology; surface topography measurement, characterization, and application; the mechanics of surfaces in contact; the development of lubricant films; and failure of rolling element bearings. The purpose of this course is to increase relevant technical knowledge and bridge the gap between component design and component failure, as a result of relative motion between surfaces in contact.

This course builds on the foundations of the Essential Course and challenges the experienced engineer in areas such as internal loading and Hertzian stresses, failure initiation criteria, friction & wear, and fatigue life calculation methods. This is an exceptional course for engineers with 2-3 years work experience in rolling element bearings or past attendees of the Essential Concepts of Bearing Technology. A general knowledge of the basic bearing types and terminology is required.

Learn the fundamentals of gear manufacturing in this hands-on course. Gain an understanding of gearing and nomenclature, principles of inspection, gear manufacturing methods, and hobbing and shaping. Utilizing manual machines, develop a deeper breadth of perspective and understanding of the process and physics of making a gear as well as the ability to apply this knowledge in working with CNC equipment commonly in use.

This course is specially designed for engineers and others with technical backgrounds that have had limited exposure to rolling element bearings and need to adapt their technical training to bearings or seek an upgrade to their technical knowledge. The Essentials Course focuses on understanding basic internal geometry, tribology, bearing attributes and applications and explores the basic concepts around manufacturing methods, loads, internal load contacts, lubrication and failure.

This course will cover all aspects of gearbox concept, development, design, and through the initial stages of analysis as related to product requirements. We will review all the most common EV transaxle architectures, power flow and layout and the ‘whys’ of packaging as such. Independent of the architecture and / or layout, there are many similarities in the functional and operational requirements of an EV transaxle gearbox. We will work through all of those and develop a workable set of requirements that will then be used as the design basis. From a high-level point of view the ‘Big’ difference between transaxles for EVs (Electric Vehicles) and transmissions designed for more traditional Manual Transmissions (MTs) and / or Automatic Transmissions (ATs) is the lack of the ‘noisy’ internal combustion engine or ICE motor. An internal combustion engine driving into a typical gearbox provides a great deal of NVH masking. Thus, we obviously need to design quieter gearboxes to reduce the potential of observed gearbox NVH, now potentially unmasked by the lack of the ICE signature and magnitude. However, and moreover, the signature from an ICE is much different than from the electric motor. The new input signature, frequency, and magnitude, cause a shift to higher frequencies and generally lower magnitudes of vibrational energies. That in turn becomes a more significant consideration in terms of gear design and application. We will discuss this and more throughout the course.

Gain a solid and fundamental understanding of gear geometry, types and arrangements, and basic design principles. Starting with the fundamental definitions of gears, conjugate motion, and the Laws of Gearing, learn the tools needed to understand the inter-relation and coordinated motion operating within gear pairs and multi-gear trains. Basic gear system design process, gear measurement and inspection techniques will also be explained. In addition, the fundamentals of understanding the stepwise process of working through the iterative design process required to generate a gear pair will be reviewed. Learn the steps and issues involved in design refinement and some manufacturing considerations. 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 also be covered. We will conclude with an overview of gear failures, failure mechanisms, and possible root causes, as a workshop style discussion.

This course is intended to be both an overview of worm and wheel gearing, as well as an introduction to the application, design considerations, practical development techniques for manufacturing, and finally how best to apply worm and wheel technology. We will cover some design development, lubrication considerations, and failure modes and causes.

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.
