Planetary helical gears are widely used in various transmissions such as helicopters, automobiles and heavy industry due to their substantial particularities of compactness, large torque-to-weight ratio and weak bearing loads. Their efficiency is affected by manufacturing errors and tooth faults. To scrutinize the effect of these defects, a three dimensional helical planetary gear model was developed. The energetic Lagrange formulation was used to recover the equations of motion and the modal characteristics of the system. The dynamic response was computed by an iterative spectral method. Eccentricity, profile error and tooth pitting occurring during running were modelled. The effects of these defects on the dynamic response of the planetary gear were discussed in order to extract their features.
