 Thefailures in reducing speed gearboxes or speed multipliers with gears havetraditionally been diagnosed by means of vibration analysis. Recently there hasbeen noticed the possibility of making a diagnosis based on the tracking of thestator current of the motor driving the box or its electromagnetic torque.These variations, unlike vibration studies, have the advantage of beingnon-invasive. This work aims to evaluate the ability of fault detection anddiagnosis from the spectral analysis of the torque. On an actual application,the behavior of the frequencies associated with the fault according to theengine load condition is analyzed. Conclusions about the possibility ofdetecting failures of different severity over a tooth of a toothed wheel areobtained.
