Gear geometry is thought to be complex and considered a ‘black art’. This seminar will dispel this myth and provide a basic knowledge of spur and helical gear geometry and how gears work. The course includes 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; gear pairs; centre distance; working pressure angles; tooth thickness and backlash and non-standard geometry; contact ratios and start of active profile calculations.
The British Gear Association (BGA) is a trade association that promotes the technical and commercial interests of manufacturers, distributors, academics and others involved in the Power Transmissions industry in the United Kingdom.
The Association speaks with authority on behalf of the industry both nationally and internationally and its ability to help companies and individuals involved in the industry is widely recognised by government, the media and industry. The Association is well-represented on British and International Standard committees and provides the Chairman of the British Standards Institution's MCE/5 Committee on Gearing and the Chairman to ISO TC60 sub committee SC1.
