In a rotational system composed of a motor, star-type planetary gear increaser and dynamometer, a rotating shaft with a sun gear, which is supported by three planet gears through backlash, shows abnormal lateral vibration above a certain rotational speed during load operation. The value of the frequency of the vibration is three times that of the internal gear speed. The onset speed and amplitude of the vibration are strongly affected by the load torque. Effects of the number of planet gears, torsional stiffness of coupling and mass of the shaft on the lateral and torsional vibration of the system were experimentally investigated. Natural frequencies of the system and self-centering loci of the shaft were also measured. The results show that the abnormal lateral vibration occurs when the rotational system generates torsional resonance and the gear teeth separate. Separation of the teeth is strongly influenced by the load torque.
