Jain, S and Whiteley, P and Hunt, H (2012) Determining vibration signature of a defective planet bearing in a wind turbine epicyclic gearbox. 19th International Congress on Sound and Vibration 2012, ICSV 2012, 4. pp. 2722-2729.Full text not available from this repository.
Planet bearings of wind turbine epicyclic gearboxes are considered as one of the most critical components due to their high failure rate. In order to develop effective vibration based detection algorithms for these bearings, a thorough understanding of their vibration signature is required. In this paper, we investigate the vibration behaviour of an epicyclic gearbox in the presence of a defective planet bearing both theoretically and experimentally. We also identify different sources of modulation sidebands using an analytical model which includes ring gear flexibility and planet bearing defects. The findings from this work will help engineers to develop more effective fault detection algorithms.
