高速回転可能なツーウェイクラッチの開発

抄録

A usual two-way clutch cannot rotate at high speed. Therefore, it is not suitable for a device that needs to rotate at high speed. In this paper, we propose a two-way clutch mechanism that can rotate at high speed. A one-way clutch can rotate at high speed in comparison with a two-way clutch. A two-way clutch restricts the transmission-direction of the torque only from the input shaft to the output shaft. The one-way clutch restricts the rotation-direction of a shaft in one direction. In the proposed mechanism, a planetary gear is sandwiched between two one-way clutches. When the rotation direction is changed, the planetary gear moves to switch the meshed one-way clutch. As a result, the mechanism works just like a two-way clutch mechanism. We experimentally confirmed that the mechanism works as expected.
