ARTICULATED ARM TYPE INDUSTRIAL ROBOT WITH DRIVING LINK MECHANISM.

摘要

A driving link mechanism for transmitting torque to driven elements of a robot from a driving source, which is constituted of two link mechanisms spaced apart and different in motion phase from each other, wherein the torque is constantly transmitted from the driving source to the driven elements of the robot through at least one of these two link mechanisms, whereby, even when a state of a dead center occurs in one of the link mechanisms, the other link mechanism transmits the torque, so that work regions of the driven elements of the robot can be expanded.
