3. How do you reduce gearbox & electric motor noise?

To solve gearbox & electric motor noise problems, the first step is to determine the type of noise that is objectionable. What’s considered gear noise depends on the speed of operation. Use qualitative and quantitative terms to describe how design factors and manufacturing mistakes play into the noise equation. Then discuss with the design team (and potential suppliers) the problems of gear noise, dynamics, measurement, and modeling.
