Robot articulated joint with cable reduction drive has pair of pulleys mounted on support with pulley mounted on arm and connected by cable to motor

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.
