Due to its comprising leveling setup the test bench can be used to align the test specimen by metal bellow couplings to the torque measuring shafts. The enclosure of the test rig including a cooling fan allows for preciously conditioning a planetary gearbox to a desired operating point, defined by the speed, torque and temperature to automatically measure the characteristics diagrams of a specimen of interest based on space-filling methods. Additional accelerometers and microphones can be added in order to perform identify mechanical vibration as well as noise signatures.
Research has been conducted to identify and capture vibration signals of typical low power-range planetary gearboxes to analyze dependencies of vibration signatures and possible micro-geometric deviations of the gearing and gearbox as currently aimed for in predictive maintenance researches. Thereby a high effort was made on detecting uncertainties in the analysis of aggregated data. Gathered data steps were taken to link defects in the gear train to manufacture imperfections resulting in vibration signatures.
