ARTICULATED MECHANISM COMPRISING A CABLE REDUCTION GEAR FOR USE IN A ROBOT ARM

摘要

The robot articulated joint has a base (1) with a support and a joint rotating about a first axis (Y). An arm turns on the support around a second axis (Z) non-parallel to the first. A rotary actuator has a cable (14) between a motor (12) shaft and a pair of pulleys (17,18) mounted on the support, and a pulley mounted on the arm, to form a pair of runs (23,24) between the pulleys colinear to the first axis.
