CABLE ACTUATOR ALLOWING INCREASED JOINT CLEARANCE |
| 摘要 |
A cable actuator comprising a chassis (1), a screw (2) rotatably mounted on the chassis and driven by an electric motor, a nut (4) that engages with the screw and is combined with anti-rotation means such that rotation of the screw under the action of the motor causes an axial displacement of the nut, two cables (10) coupled to the nut on either side of same, the two cables being wound onto respective joint pulleys (11) each rigidly connected to a same joint shaft (12) and in which the joint pulleys have a helical groove, the helical grooves of the pulleys extending in opposing directions. |

1. A cable actuator including:
a chassis; a screw rotatably mounted on the chassis and driven by an electric motor; a nut that engages with the screw and is combined with anti-rotation means such that rotation of the screw under the action of the motor causes an axial movement of the nut; two cables extending symmetrically with respect to a rotation axis of the screw and coupled to the nut on either side thereof;characterized in that the two cables are wound onto respective joint pulleys both rigidly connected to the same joint shaft and in which the joint pulleys are of the type that has a helical groove, the helical grooves of the pulleys extending in opposite directions. |
