CPD - The CPD Certification Service

This seminar will include Sources of Gear Noise and Definition of Transmission Error. The Gear Design for Low Noise it will cover includes TE spur gears; TE helical gears; The relation of TE to contact ratios and the concept of integer contact ratio; the effect of misalignment on tooth contact; approaches to designing gears for low TE and TE in planetary gears. The Noise Signals information covered is tooth passing frequencies; gear pairs; planetary gears; run out; generation of side bands and ghost frequencies and their origin. 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.
