Abstract: | Planetary gears are widely used in the transmissions of helicopters, automobiles, aircraft engines, etc. They have substantial
advantages such as compactness and a large torque-to-weight ratio. In this work, a plane model of a planetary gear was investigated.
The energetic Lagrange formulation was used to recover the equations of motion of the system. A modal analysis was performed,
and the influence of gyroscopic effect in particular was scrutinized. The dynamic response was computed by an iterative spectral
method. The excitation is induced by time-varying the gearmesh stiffness. The cases of a healthy planetary gear and one with
the presence of eccentricity and profile error were compared. The influence on the transmission ratio was also studied. |
