In the paper the influence of tooth root notch and its depth on the frequency response of the gear drive by the vibroacoustic method has been treated. Different notch depths were made by the wire erosion and represented a perfect substitute for real cracks. It is well known that cracks occur due to overloads, wrong design of overloads or defects in the base material. Tests were made for different rotation speeds and torque. Dynamic signals were captured by two microphones and analysed by Fourier transform. A frequency power spectrum was found with significantly varying amplitudes depending on changing notch depth, torque, rotation speed, and also with varying number of side-band frequencies. This fact grooves that the above mentioned method is suitable for diagnosing gear drives.
