In the paper the possibility of model based detection of local faults in helical gears is analysed. Presented methods allow early detection of anomalies in the time vibration signal that could be linked to the fatigue tooth damages like pitting and tooth fracture. They relies on calculation of different signal parameters for the consecutive meshes and allows for acquiring information about the disturbances of the meshing process for particular tooth pairs. They permit the observation of the energy density changes for the consecutive teeth (or tooth pairs) during the normal exploitation of the gearbox. All the described methods are based on analysis of the time signals. Contrary to the methods based on spectral analysis these methods allow for precise localisation of gear defects and linking them to the particular pinion or gear teeth. Additionally they could be used in the procedure of gear manufacturing quality assessment.
