Please note this training is over 4 sessions – you will need to attend all sessions to complete the course.

Cylindrical gear stress analysis – Part 1 Introduction to gear loads, failure modes and geometry

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to perform gear contact and bending fatigue stress analysis. The course covers the application of ISO 6336 bending and contact stress analysis methods. No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation and Introduction to Gear Geometry online courses.

It is applicable to gear designers, users of ISO 6336 and those who are involved with gear manufacture and want to understand why designers use tight tolerances and high grade materials.

The session will include a short introduction on Teams before you access some video presentations individually and try some easy quizzes to test your knowledge. We then get back together on Teams later in the morning to run through the quiz answers and discuss any questions you have and summarise what we have covered. PDFs of the PowerPoint presentations and supporting training information will be sent prior to the event.  Also, you will have access to the video sessions for 7 days to run over things again if needed.

The 1st session will:

  • Remind us how gears work, gear loads and load direction, what increases the instantaneous load as gear teeth mesh.
  • Define common gear failure modes.
  • An introduction to ISO 6336, the scope of the document and its key features.
  • The principle of how we calculate gear stress safety factors.
  • Selected terms and symbols- how the ISO symbol strategy works.
  • We have included plenty of time for questions and discussion.

Key skills and knowledge:

By the end of the session, you will understand the challenge associated with predicting gear loads, how gears fail prematurely and the principles we use to calculate gear safety factors for contact and bending fatigue.

Cylindrical gear stress analysis – Part 2 Introduction to gear load modifying factors and permissible stresses for contact and bending fatigue

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to perform gear contact and bending fatigue stress analysis.

Also, you will have access to the video sessions for 7 days to run over things again if needed.

The 2nd session will:

  • Focus on generic factors that influence the applied predicted load based mainly on ISO 6336-1
  • Load application factors and Miners Sum cumulative damage
  • Load dynamic factor
  • Accounting for shaft, bearing and housing deflections
  • Random manufacturing errors
  • Load distribution factors- key influences
  • The effect of micro geometry corrections on load
  • Review permissible stresses- options in ISO 6336-5.
  • We have included plenty of time for questions and discussion.

Key skills and knowledge:

By the end of the session, you will understand the challenge associated with predicting gear loads, how gears fail prematurely and the principles we use to calculate gear safety factors for contact and bending fatigue.

The 3rd session will:

  • Introduce bending stress key influence factors
  • Show the effect from reverse torque loading and the effect on bending stress
  • Introduce contact stress key influence factors
  • Review example analysis results
  • We have included plenty of time for questions and discussion.

Key skills and knowledge:

By the end of the session, you will understand the challenge associated with predicting gear loads, how gears fail prematurely and the principles we use to calculate gear safety factors for contact and bending fatigue.
