Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing
Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear […]
Using simulation to evaluate part green shape to reduce distortion during plug quenching
Determining the heat-treatment geometry (green shape) for complex gears is not a trivial task. Mass distribution becomes critical in determining […]
