Abstract

The application of RV reducer is becoming more and more extensive, and the condition monitoring of its transmission system is becoming more and more important. Motor current signature analysis (MCSA) enables non-intrusive and cost-effective monitoring of information and has been widely used for condition monitoring. An RV reducer test rig was built up to simulate the angular misalignment between the driving motor and the RV input shaft. The motor stator current signal was collected under the different levels of the angular misalignment. The signal was analyzed both in time domain and frequency domain. Moreover, the characteristic frequencies of the RV reducer can be clearly observed in the motor current spectrum. The changes in the amplitudes of the characteristic frequencies were comprehensively studied, which gradually increase with the increase of the level of angular misalignment. The rotational frequency fr2 can be an indictor for diagnosis of angular misalignment.
