Introduction to Gears

This seminar is designed to provide gear novices with a general understanding of gear nomenclature, geometry, and arrangements. Starting with the basic definition of gears, conjugate motion and the "Laws of Gearing", you will gain a solid understanding of gearing and the fundamentals of rotary motion transfer through gear-trains. Gear classifications, tooth forms and geometry, and very high-level application considerations, manufacturing processes, and inspection techniques will be covered.

Attendees will receive a copy of the book, Gear Design Simplified, by Franklin D. Jones & Henry H. Ryffel.

What Will You Learn

By attending this seminar you will be able to:
  • Describe the "Law of Gearing", conjugate action and involute profiles
  • Identify the various gear types and configurations
  • Articulate the various definitions and terms used in gearing
  • Identify the function and operation of all gear arrangements
  • Articulate basic design considerations, nomenclature and inter-relationship of gear forms and motions
  • Describe the various manufacturing processes and inspection techniques commonly used in industry today

Is This Course For You

This seminar is designed for individuals with little or no previous experience in gear systems. Engineers new to the field of gearing, sales and marketing people responsible for interacting with gear engineers, component suppliers, and vehicle platform powertrain development specialists who have not been previously involved in gear system specification or design will benefit from this course.
