Gear Noise and Transmission Error

Description

Date: 12th March 2026

Time: 9:30am - 4:30pm

Location: Hexagon Manufacturing Intelligence

Tutor: Dr Michael Platten

Fee: Non Member £450/ BGA Member £250*

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.
