Noise levels of motor vehicles are becoming an important subject of environment regulation. Recently, a reduction in the noise and vibration of planetary gear drives to be used for an automatic transmission of passenger cars has become an important project. The authors designed and made a planetary gear testing machine which can test the component planetary gear trains in an automatic transmission of the cars. The phase difference in gear tooth meshing is given to the planet gears which make contact with the sun and internal gears. As component gears, shaved and hardened helical gears with and without grinding were used and the rotational speed and the tooth load were changed. The experimental results clearly showed that a reduction in running noise and vibration was surely obtained when the phase difference in tooth meshing was introduced.
