ISO 6336 Seminar

Do you understand gear rating or need to know more? Applying the latest analysis methods could save you money and make your company more competitive. This seminar will give you the opportunity to understand and explore the stress analysis procedures published in ISO 6336:2006 and discuss ideas and implications with other members of the industry. However, the latest standards are rather daunting to those who are new to them so the purpose of this seminar is to make it much easier to understand how it works.


The seminar will:

  • Provide a brief introduction to how gears work and fail o Provide an overview of how the ISO 6336 standard works, its key influence factors, what it will do and more importantly, what it won’t do
  • Discuss the calculation of tooth bending and contact stresses in a given set of cylindrical gears o Show how we can increase power density and reduce manufacturing costs
  • Discuss what the safety factors actually mean
  • Use examples to highlight key features and limitations of the ISO 6336 method


Key skills and knowledge:

At the end of the seminar you will know how ISO 6336 works, be familiar with its terms and symbols and understand the key influencing factors which affect bending and contact stress. You will be more confident using ISO 6336 software packages.



Gear Optimization

Applying the latest ISO 6336 stress analysis standard implements best practice but it will not guarantee a low noise or low risk gear set. This requires the selection of appropriate macro gear geometry and the specification of micro geometry corrections to compensate for random manufacturing errors and elastic deflection of gears, shafts and gearbox under load. This seminar will introduce and apply strategies for maximizing gear performance, increasing power density and minimizing manufacturing costs and risk.

The seminar will cover:

  • Optimization models
  • Minimizing Transmission Error (TE) and noise by macro gear geometry application
  • Micro gear geometry- tip relief and helix correction strategies
  • The benefits and limitations of parabolic tip relief vs. linear tip relief
  • The benefits and limitations of helix crowning vs. end relief
  • Compensation for random manufacturing errors and elastic deflections
  • Examples to quantify the effectiveness of the different options


Key skills and knowledge:

At the end of the seminar you will be able to specify gear geometry with confidence, understand the difference between spur and helical gear designs, understand the benefits and limitations of non-standard gear geometries and specify gear micro geometry based on a sound strategy.
