Analysis and modification of a single-mesh gear fatigue rig for use in diagnostic studies [PDF]
A single-mesh gear fatigue rig was analyzed and modified for use in gear mesh diagnostic research. The fatigue rig allowed unwanted vibration to mask the test-gear vibration signal, making it difficult to perform diagnostic studies.
