Introduction: Sources of Gear Noise; Definition of Transmission Error; Gear Design for Low Noise; TE spur gears; TE helical gears; The relation of TE to contact ratios and the concept of integer contact ratio; Effect of misalignment on tooth contact; Approaches to designing gears for low TE; TE in planetary gears; Noise Signals; Tooth passing frequencies; Gear pairs; Planetary gears; Run out ; generation of side bands; Ghost frequencies and their origin; Noise measurement; Practical aspects of noise measurement are considered in order to correctly diagnose the cause/source of the noise it’s necessary to correctly identify the frequency.
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.
