Title (EN) ARTICULATED ROBOT
(FR) ROBOT ARTICULE
Abstract:
(EN) An articulated robot having at least two control arms (4), (7) and two reduction gears disposed at the joints of both control arms (4), (7) and facing each other on the same axis, wherein the two reduction gears consist of first and second harmonic drive reduction gears equipped with a common circular spline (60) fixed to the joint of one of the control arms (4), (7) and brackets (40), (50) fitted to one of the ends of the common circular spline (60) in such a manner as to rotate relatively to the circular spline (60) and connected to the joints of the control arms (4), (7). Thus the present invention provides an articulated robot which makes it possible to reduce the number of components, to render assembling easier, to ensure stable high accuracy and to produce the robot economically.
(FR) Robot articulé doté d'au moins deux bras (4), (7) de commande et d'au moins deux rouages intermédiaires disposés aux articulations des deux bras (4), (7) de commande, se faisant face sur le même axe, dans lequel les deux rouages intermédiaires se composent de rouages intermédiaires d'entraînement de deuxièmes harmoniques équipés d'une cannelure (60) circulaire commune fixée à l'articulation d'un des bras (4), (7) de commande, et de consoles (40), (50) montées sur une des extrémités de la clavette coulissante (60) circulaire commune de manière à tourner par rapport à la clavette coulissante (60) circulaire, et connectées aux articulations des bras (4), (7) de commande. Ainsi la présente invention constitue un robot articulé permettant de réduire le nombre de constituants, de faciliter l'assemblage, de garantir une haute précision stable et de produire le robot à faible coût.
