Kurzbeschreibung (Abstract)
The gear mesh vibration caused by planetary geartrains is modulated. Small planetarygearboxes, commonly used in servo drives, are examined experimentally and numerically.The goal is to link the modulation of the gearbox vibration to the deviations from the idealgeometry caused by manufacturing and assembly. Operational modal analysis shows that,while the dynamical behavior of nominally identical gearboxes is very similar, their mod-ulation is not. The modulation also strongly depends on the operating conditions, such asspeed and torque. Therefore, the modulation is aggregated to a vibration signature. In thevibration signature, distinct features are present. These can be linked to the eccentricity ofthe gears using numerical multi-body simulation and correlation analysis.
