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

CYLINDRICAL GEAR GEOMETRY PART 1- HOW INVOLUTE GEARS WORK

This is the first session of 4 to help introduce you to cylindrical gear geometry.

Gear geometry is thought to be complex and often considered a ‘black art’.  This short on-line session will dispel this myth and provide delegates with a basic knowledge of how gears work and cylindrical gear geometry.  No prior gear knowledge is required.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry and want to understand what all the fuss is about.

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 24 hours to run over things again if needed.

The session will:

  • Remind us why we use gears.
  • Introduce us to the requirements of gears and the involute curve.
  • Show how gears work.
  • Show why gears need to be precise.
  • Explain why gears are noisy and how we make them quiet.
  • However, we wont look at gear design or gear calculations- that’s for later sessions.
  • We have Included plenty of time for questions and discussion.

Key skills and knowledge:

At the end of the seminar you will understand how gears work and understand what is important to make gears work properly.  Designing, manufacturing and inspection processes make much more sense when you understand basic gear geometry.  You will be ready to develop your knowledge further in the next gear geometry sessions from the BGA.

CYLINDRICAL GEAR GEOMETRY PART 2- AN INTRODUCTION TO BS ISO 21771:2007

This is the second session of 4 to help introduce you to cylindrical gear geometry.

Gear geometry is complicated, but this short on-line session will build on the part 1 of this series and introduce you to ISO 21771 on cylindrical gear geometry.  The standard provides gear geometry calculations and is daunting, but this session will start your introduction to it, step by step.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry.  Many of us use commercial software or spreadsheets to perform gear calculations developed by others, but each of us needs to know what the values mean and where they come from.

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 24 hours to run over things again if needed.

The session will:

  • Remind us how easy it is to specify gear geometry.
  • Explain why it’s more complicated in practice (spoiler alert- its due to how we make gears).
  • Introduce us to ISO terms and more importantly to the symbols used in ISO gear standards. ISO symbols can be considered the international language of gears.
  • Introduce some basic geometry calculations and diagrams from ISO 21771. We will show you how to interpret these.
  • Include some basic gear calculations which require a scientific calculator.
  • We will go through the answers at the end of the session.
  • We have Included plenty of time for questions and discussion.

Key skills and knowledge:

Designing, manufacturing and inspection processes make much more sense when you understand basic gear geometry.  You will be familiar with some common gear terms and symbols be able to understand and perform basic gear calculations with BS ISO 21771 (which is available for BGA members via the BGA website).  You’ll be ready to develop your knowledge further in the next gear geometry sessions available from the BGA.

CYLINDRICAL GEAR GEOMETRY PART 3- GEAR PAIRS AND THEIR RELATED GEAR GEOMETRY

This short on-line session will build on parts 1 & 2 of this series to develop your expertise and introduce you to profile shift coefficient, a subject that often causes confusion, gear pair geometry and tooth thickness calculations.  The sessions will be based around ISO 21771:2007 standard and show you how to interpret the confusing gear pair drawings so you can confidently use the standard.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry.  Many of us use commercial software or spreadsheets to perform gear calculations developed by others, but each of us needs to know what the values mean and where they come from.

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 24 hours to run over things again if needed.

The session will:

  • Remind us how gears work
  • Introduce gear pair geometry and lines of contact.
  • Introduce the concepts of working pressure angle and show you how we work out where gears start to contact on the tooth flank.
  • Introduce you to profile shift coefficient, ‘x’, why we use it, and what effects it has on gear geometry.
  • Introduce you to basic tooth thickness calculations.
  • Introduce the relevant geometry calculations and diagrams from ISO 21771.
  • Allow you to test your knowledge with quizzes but don’t worry, we will go through the answers at the end of the session.
  • We have Included plenty of time for questions and discussion.

Key skills and knowledge:

Designing, manufacturing and inspection processes make much more sense when you understand gear geometry.  You will be familiar with common gear terms and symbols be able to understand and be confident using gear calculations in BS ISO 21771 (which is available for BGA members via the BGA website).  You’ll be ready to develop your knowledge further in the next sessions available from the BGA looking at gear geometry that relates to gear performance.

CYLINDRICAL GEAR GEOMETRY PART 4- PERFORMANCE RELATED GEAR GEOMETRY.

This short on-line session will build on the earlier parts of this series and introduces you to how gear geometry influences gear performance.  Some gears are nosier than others due to their design.  We will show you why this is.  The sessions will be based around ISO 21771:2007 standard so you can confidently use the standard when the session is finished.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry.  Many of us use commercial software or spreadsheets to perform gear calculations developed by others, but each of us needs to know what the values mean and where they come from.

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 24 hours to run over things again if needed.

The session will:

  • Show why there are performance differences between spur and helical gears
  • Define what is overlap ratio on helical gears and its relationship to gear noise/vibration.
  • Transverse contact ratio and its relationship to stress and noise.
  • Introduce high contact ratio gears and show why they are used.
  • Introduce different types micro geometry corrections.
  • Introduce the relevant geometry calculations and diagrams from ISO 21771.
  • Allow you to test your knowledge with quizzes but don’t worry, we will go through the answers at the end of the session.
  • We have Included plenty of time for questions and discussion.

Key skills and knowledge:

Designing, manufacturing and inspection processes make much more sense when you understand gear geometry.  You will be familiar with some common gear terms and symbols be able to understand and perform basic gear calculations with BS ISO 21771 (which is available for BGA members via the BGA website).  You’ll be ready to develop your knowledge further in the next gear sessions available from the BGA that refer to stress analysis, and measurement and manufacturing.
