This course is a comprehensive overview of the industry. It begins with a little history of gearing and proceeds through the topics of Parallel axis gear basics, Involute tooth form, Description of the gear, Diametrical pitch/Module, Pitch, and Pressure angle. The course ends by defining a series of 37 crucial terms used in gearing. Students will also receive a copy of the ANSI/AGMA 1012-G05 Gear Nomenclature, Definitions of Terms with Symbols.

This course is designed to be a level one gear inspection course. The topics covered in this course include categories of measurement on a gear, double flank composite inspection, single flank composite inspection, sequence of measurements, when should gear elements be measured, mean helix slope deviation, and classification of gear quality.

This course is designed to present the basics of hobbing to hobbing machine operators, gear technicians, and engineers.

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.

There is a distinct difference between “designing” a gear and “optimizing” a gear design. In this course, we will address the optimization process via an understanding of those factors beyond basic banding and pitting ratings. Optimization may focus on load capacity, economy of production or minimization of overall gear system envelope. In this course we will learn how to improve gear designs via optimization and gain new insight into concepts presented through illustrations and demonstrations. Explore all factors that go into good gear design from life cycle, load, torque, tooth, optimization, and evaluating consequences.
