Recently, planetary gear trains have been widely used in hybrid vehicle power distribution systems and electric vehicle reduction systems. In this study, we considered a novel three-axis drive design for a planetary gear train that uses universal joints. The proposed gear train treats the planet gear axis (rotation component) and the carrier axis (revolution component) as a coaxial drive unit using universal joints. The ring gear serves as the drive shaft. The rotational speed of the planet gear based on the output rotational speed of the ring gear was lower than that of conventional 2K-H gear train systems. As such, the proposed planetary gear train may exhibit reduced mesh frequencies and vibration noise. In this study, a prototype of the planetary gear train was developed, and experimentation was performed to determine its application potential as a transmission mechanism.
