Abstract
Presented studies are aimed at developing of new and improving of existing methods of vibration signal analysis to detect local gears damages during their operating.
The new method of calculating the modulation coefficient showed low sensitivity to the place of mounting of the vibration sensor and makes it possible to use in the absence of information about the vibration activity of the gear drive in the previous workable condition.
A technique for designing and using unique wavelets was developed. The technique reflects the specifics of real processes in the interaction of meshing teeth and adapted for gears vibration analysis. Using of unique wavelets can noticeably increase the wavelet coefficients sensitivity to changes in gears condition.
