When cracks are initiated in a helical gear pair, the mesh stiffness and vibration response of the gear pair will be affected. Unlike previous studies on gear crack, in which only the transverse gear stiffnesses are calculated due to gear crack, or purely uniformly distributed gear crack are modelle...
