Case Study:
Transmission Casing

Client
UK Automotive Consultancy

Objective
To predict and reduce the noise generated by a transmission system due to gear whine phenomenon.

Scope

• Dynamic analysis of the noise generating gear pair
• Determination of the transmission error and its propagation while rotating
• Optimization of the gear micro geometry to increase contact ratio and make transmission smoother

Success
Optimizing the gear pairs helped in reducing the transmission error, reducing a major component of gear whine.
