Gearbox CSI

February 27–29—Live Online Course

A good understanding of individual failure modes and the failure scenarios that led to the actual system failure is an essential skill for designing gear/bearing systems that will operate properly for their full design life. In this course, we will define and explain the nature of many gear and bearing failures and we will also discuss and describe various actual failure scenarios. In addition, a detailed primer on bearing technology prefaces the failure scenario discussions. You will gain a better understanding of various types of gears and bearings. Learn about the limitations and capabilities of rolling element bearings and the gears that they support. Grasp an understanding of how to properly apply the best gear-bearing combination to any gearbox from simple to complex.

Design Basics for Spur and Helical Gears—Winter

February 13—Live Online Course

Learn how to develop and understand customer gear drive application specifications and target performance expectations. Review, calculate, and select basic gear terminology variables and design parameters that define tooth bending and contact rating safety factors on two real-life examples. Learn how to optimize gear fatigue Safety Factors for a given target design life and fit new gear designs and ratios into existing center distance using profile shift. Use commercially available software to develop gear geometry factors, calculate, and optimize gear set power density and performance. Review common gear failure modes if the design or final accuracy does not meet application requirements. Discuss the time and cost of more than 20 other gear drive component functions and drive development steps through prototypes to shipment of compliant assembled production drives. There will be an opportunity to discuss gear design challenges that may be unique to participant industries.

Detailed Gear Design

April 16–19—The Westin Arlington, Arlington, VA

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.

EV Automotive Transmission System Design

April 23–25—The Graduate Hotel; Ann Arbor, MI

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.
