LAST CHANCE TO REGISTER: GEAR NOISE AND TRANSMISSION ERROR
Date: 12th March 2026
Time: 9:30am - 4:30pm
Location: Hexagon Manufacturing Intelligence
Tutor: Dr Michael Platten
Fee: Non Member £450/ BGA Member £250
PLEASE NOTE THIS IS AN IN PERSON COURSE. REGISTRATION CLOSES 4TH MARCH 2026.
This seminar is aimed at both gear users and gear manufacturers. Dr Michael Platten will examine the basic causes of gear noise and the path from initial gear design and manufacturing errors to the final noise generation.
Seminar programme:
Introduction
· The sources of Gear Noise
· Definition of Transmission Error (TE)
Gear Design for Low Noise
· TE and spur gears
· TE and helical gears
· The relation of TE to contact ratios and the concept of integer contact ratio
· Effect of misalignment on tooth contact
· Practical approaches to designing gears for low TE
· TE in planetary gears (theory of factorising and non-factorising)
Noise Signals
· Tooth passing frequencies
· Gear pairs
· Planetary gears
· Run out ; generation of side bands
· Ghost frequencies and their origin
Noise measurement
The practical aspects of noise measurement will be considered where in order to correctly diagnose the cause/source of the noise, it is necessary to correctly identify the frequency. Reference will be made back to the section on "Noise Signals.”
Key skills and knowledge:
The student will be able to differentiate between actual gear noise problems and noise generated by other sources, identify the remedial action required to alleviate the problem and where to seek additional help if required.
