| 摘要 |
The present invention relates to a one-way reduction gear and, more particularly, to a one-way reduction gear capable of transmitting power in one direction and preventing reverse rotation by itself while excluding a brake device. To this end, the one-way reduction gear of the present invention comprises: a power transmission part (210) including a main shaft (212) connected with a motor in order to receive power; a power input part (310) including an input planetary gear (320) engaged with the main shaft (212) to receive power; a power relay part (410) including a ring gear (412) that relays power of the power input part (310); and a power output part (510) including an output planetary gear (520) that forwards, to a carrier (512), the power transmitted from the power relay part (410). |
