Planetary Gear systems (PGs) are widely used in many mechanical engineering applications such as industrial robots, mining machinery and aircraft transmission. During their fitness they can be affected by several kinds of damage for example crack and spalling that are the most systematic malfunction. As those systems are frequently provoked in non-stationary condition defined as variable loading and variable speed regimes, their diagnosis under these regimes using the vibration response presents a huge challenge for research and investigation. In this work, the vibration response of two-stage planetary gears in presence of spalling faults are investigated during the down-time excitation regime. The system is already preloaded, and a ramp of speed is applied on the system using a frequency inverter and the sensors are mounted on the ring gear components. A series of measurements tests are carried out using an experimental test bench where a spalling defect is introduced to one of the planet components. The paper examines the damages detection using time domain, frequency domain and order domain analysis approaches. In the end, the obtained results that are processed with angular order domain analysis based on the angle domain order tracking method shows an interesting result compared to others method. |
