Abstract
Planetary gear set is widely used in hybrid vehicle as a power distribution system or in electric vehicle as a high reduction system, but its noise and vibration problem has emerged. There are many reports dealing with two-axes driving or displacement of planet gear under its condition, but we can see few reports dealing with about three-axes driving. In the present report, three-axis driving is tested with three-axes torque measuring and dynamic characteristic is investigated focusing on planet gear. As a result, it's confirmed that transition forces around planet gear are balanced and torque is also balanced around instantaneous rotation center. Meshing frequency in this condition are harmonics of two meshing frequencies, which are meshing frequency of ring gear and meshing frequency of planet gear. Input power of ring gear is distributed to carrier and sun gear through planet mode, star mode and solar mode.
