Abstract
A method for identifying gear tooth numbers in a gearbox using data obtained from a vibration measuring device delivered to a data acquisition device and data delivered by a user to a computer device, comprising: processing data delivered by a user to the computer device, where the data comprises a gearbox ratio and a number of stages of a gearbox for calculating a potential gear tooth combination in each stage of a gearbox, calculating frequencies of characteristic features for each potential tooth combination using the data delivered at the processing data, measuring vibration signals of the gearbox, calculating a frequency spectrum from measured data delivered at the measuring, determining an amplitude of components, of the frequency spectrum delivered at the calculating a frequency spectrum at frequencies of characteristic features for each potential tooth combination delivered at the calculating frequencies of characteristic features.
