Date: 14th, 15th, 21st & 22nd May 2024

Time: 9:30am - 12:30pm

Platform: TEAMS 

Tutor: Rob Frazer & Rob Lambert

Fee: BGA Member Free / Non Member £350

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

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.
