Abstract: The wear debris in the lubricating oil carried a large amount of wear information of gearbox. Through the on-line monitoring sensor of wear debris, some important parameters of the wear debris (including size, quantity, production rate, etc) can be monitored, which can judge and speculate the wear state of gear box. At present, the accurate corresponding relation between the relative characteristic parameters of on-line monitoring wear debris and the wear state of the gear box had not been studied in depth. In this paper, firstly, the reliability of the wear debris sensor was verified by method of off-line detection, and then through the full life test of gear box carried out by independently developed test bench, the trend of wear debris quantity and production rate in diffe-rent sizes could judge the wear degree and development trend. Finally, the iron spectrum analysis and other means were used to further verify the predictive accuracy of gearbox failure made by on-line monitoring. The results showed that the wear debris information (including size, quantity, production rate) based on oil on-line monitoring can commendably judge and forecast the wear state of gear box.
