Location: Design Unit – Newcastle Upon Tyne
Tutor: Rob Frazer
Gear geometry is thought to be complex and often considered a ‘black art’. This seminar will dispel this myth and provide delegates with a basic knowledge of spur and helical gear geometry and how gears work. No prior gear knowledge is required.
We will look at how gears work and some basic calculations relating to gear geometry. 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. You will need a calculator because we are going to do some simple sums!
The Seminar will cover:
* How involute gears work
* An introduction to the involute gear geometry standard ISO 21771, BGA Code of Practice 07 and gear terms and symbols
* The basic rack, cutting tools and basic gear sums relating to spur and helical gears o Gear pairs, centre distance, working pressure angles, tooth thickness and backlash
* Non-standard geometry, contact ratios and start of active profile calculations
* Plenty of examples to work through – please make sure you bring a basic scientific calculator!
Key skills and knowledge:
At the end of the seminar you will understand how gears work, be competent with basic calculations relating to gear geometry, understand the basic terms and symbols and have a greater understanding of what is happening when you use gear software packages. Design, manufacture and inspection processes make more sense when you understand gear geometry.
