Abstract: The paper focuses on working out an algorithm for spur gear condition monitoring, based on the results of numerical simulation. The nonlinear mathematical model has been used for investigation of the dynamic parameters of the cylindrical spur gear with defective teeth. Backlash between gear teeth, backlash in bearings, time-varying mesh stiffness, and variations of the centre distance have been evaluated in the model. Diagnostic parameters suitable for determining the condition of the gears under investigation have been established. Frequency intervals mostly affected by changes in diagnostic parameters under damage have been found. An algorithm for diagnostics based on mathematical modelling, vibro-acoustic, and acoustic emission methods, and wavelet transform has been worked out.
