Aiming at the problem of condition monitoring method in the gearbox, it puts forward a new analysis method of gear box fault based on the oil temperature collected easily and establishes the temperature model of gear box by (nonlinear state estimate technology) NSET method to predict the temperature of the gear box. It is when gear box runs abnormally that the statistical features of the temperature prediction residual change largely to detect the fault of gearbox early. A statistical method is used to detect the changes of the residual mean value and standard deviation. When one of these parameters exceeds predefined thresholds, an incipient failure was flagged. And compared with neural network forecasting method, it highlights the advantages of this method.
