The paper presents laboratory investigations of some tooth surface failure in helical gears. Signal analysis is one of the most important methods used for condition monitoring and fault diagnostics, whose aim is to find a simple and effective transform to the original signals. During the laboratory investigations of helical gears, some signal changes of lateral vibration velocity of the shafts during the process of pitting growth in the operating surfaces of gear teeth have been observed. The carried out investigations reveal that the square root of the sum of the square coefficient C_ʃ(j,k,ψ) of the continuous wavelet transform (CWT) distribution and the sum of discrete values of the pseudo Wigner-Ville Distribution (WVD) amplitudes in the frequency range from 0 to 0.9 ʃ_mesh grow together with the process of pitting development. New indices of pitting wear have been suggested and compared with other non-dimensional vibration diagnostic parameters.
