PURPOSE: A cable power transfer unit is provided to adjust reduction gear ratio by combining two pulleys which are rolled in the opposite direction each other as a hollow shaft shape. CONSTITUTION: A first driving pulley(6) and a first gear are connected by a hollow shaft. A second gear(4) is pivotally connected with the first gear. The second gear receives power from a servo motor. A second driving pulley comprises a shaft which is combined with one driving pulley by passing through the hollow shaft. A shaft fixing apparatus(9) controls the degree of twist of the first driving pulley and the second driving pulley. A cable groove is respectively formed at the outer circumferential face of the first driving pulley and the second driving pulley. A first power transfer cable and a second power transfer cable are combined with the cable groove which can be separated. |
