Description
Planetary gear trains are commonly used in industry due to their high torque capability and compact size. However, the geometry and kinematics of planetary gears are very complicated. The vibration analysis of planetary gearboxes are not fully developed. In this research, the signature frequencies of faulted sun, planet, and ring gears are derived for the fault diagnosis purpose. Simulations in the time domain were conducted for three models to illustrate the impacts caused by faulted gears. Experiments were carried out on a Drivetrain Diagnostics Simulator. The signal analyses in both the time and frequency domains validate the theoretical models.
