Development of a high-speed and low-torque loss two-way clutch
In this study, a two-way clutch mechanism using planetary gear meshing was proposed. The proposed mechanism allows low torque loss and high-speed rotation instead of a larger backlash compared to a roller type two-way clutch. The unique structure of this

Dynamic Behavior of Planetary Gear : 1st Report Load Distribution in Planetary Gear
In the planetary gear, the inequality of load distribution arises on each planet gear because of random errors of manufacture and assembly. This phenomenon results in an increase of load to each part, the occurrence of vibration, and a drop in efficiency of planetary gear systems.
