Summary:The free vibration of planetary gears with equally spaced planets has been extensively studied. In a recent study, the highly structured free-vibration properties were rigorously characterized in reference. These special properties result from the cyclic symmetry of planetary gears. Because of certain design purposes and assembly limitations, however, the planets are sometimes unequally spaced and the cyclic symmetry is lost. The free vibration of systems with unequally spaced planets has not been previously investigated, and the question remains of how the highly structured free-vibration properties of equally spaced planet systems change due to unequal planet spacing. This technical note analytically investigates this question. (Author)
