ARM WITH GRAVITY-BALANCING FUNCTION

Title:

ARM WITH GRAVITY-BALANCING FUNCTION

Document Type and Number:

WIPO Patent Application WO/1980/001774

Kind Code:

A1

Abstract:

Arm having a gravity-balancing function effective for use in welding robots as well as robots employed in a variety of industrial fields. Projectively provided over the fulcrum of an arm (1) is a rotary sheave (2), whose position is perpendicularly maintained regardless of the vertical swaying of the arm (1). A wire (6) is extended from an action point (A) on a line traced by the center of gravity of the arm (1), to the rotary sheave (2), and is connected to a spring mechanism (3) which may extend by the length of elongation equal to the distance between the action point (A) and the rotary sheave (2), whereby a moment due to the weight of the arm (1) is completely balanced to provide an arm with gravity-balancing.
