Design Basics for Spur and Helical Gears – Sept. 2024

Design Basics for Spur and Helical Gears

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 which 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 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.  here will be an opportunity to discuss gear design challenges which may be unique to participant industries.

_{This course is online. A webcam on your computer equipped with a microphone and speakers/headset are required for participation. Space is limited to 20-25 participants per course. Course materials will be mailed in hard copy. Please make sure to indicate your preferred mailing address in the registration process.}

Learning Objectives

• Discuss aspects of gear tooth fatigue loading and typical failure modes as a basis for gear designs which exceed target design fatigue life.
• Understand the various form of drive loads.
• Ability to start with customer supplied gear drive application specification and develop an optimized gear design which meets or exceeds application and performance requirements.
• Review gear geometry terminology and design optimization variables beyond information available in Machinery’s Handbook, apply optimization tools currently used in industry.
• Calculate contact and bending Safety Factors as (Material and Design allowable loads) divided by (application loads) for a target design life.
• Learn how to fit a new gear ratio into existing housing and center distance.
• This course is focused on gear design, but reviews functionality of over 20 related drive components and design related processes.
• Apply design tools and gear performance enhancements.
• Discuss gear drive design process steps, time, and costs from receipt of customer application specifications through design, prototype development/testing to manufacturing and shipping production units which meet or exceed customer expectations.
• Work through two real life examples developing optimized spur and helical gearsets which exceed customer application specifications. 

Who Should Attend

This course would be of interest to high level gear grind operators, inspectors and quality assurance people who need to better understand why and how gear designs are optimized and how to interpret non-standard gear geometry.  They can also gain insight on how improper finishing techniques can contribute to pre-mature gear failures.  Entry level gear designers, process and manufacturing engineers can develop a basic understanding of gear geometry terms and variables.  Gear manufacturing project managers can develop a better understanding of time required to design and optimize a gearset that is cost effective and meets or exceeds application expectations.
