Title (EN) A DEVICE FOR TORSION-PROOF CONNECTION OF AN ELEMENT IN A ROBOT ARM OR THE LIKE
(FR) DISPOSITIF DE LIAISON SANS TORSION D"UN ELEMENT DANS UN BRAS DE ROBOT OU ANALOGUE
Abstract:
(EN) A device for torsion-proof connection of a number of elements (11, 12) in direct or indirect rolling contact with each other, which together make a robot arm or the like, whereby the elements are held together and actuated by force transmitting actuators, for example cords. The object of the present invention is to provide a device with which the individual elements of a robot arm can be torsionally locked so that it can bear significant torsional forces without detoriating the rolling characteristics of the elements. This object has been achieved by the fact that the elements (11, 12; 15) pairwise, with their rolling surfaces (13) turned towards each other, being connected with each other through a torsion member (14) which is flexible and/or jointed in the roling direction of the elements (11, 12) and which has a great stiffness across the rolling direction.
(FR) Dispositif de liaison sans torsion d"un certain nombre d"éléments (11, 12) en contact direct ou indirect de roulement entre eux, formant ensemble un bras de robot ou analogue, ces éléments étant maintenus ensemble et actionnés par des dispositifs de transmission de force, par exemple des câbles. L"objet de la présente invention est de réaliser un dispositif grâce auquel les éléments individuels d"un bras de robot peuvent être verrouillés contre la torsion de sorte que le bras peut supporter des forces torsionnelles considérables sans qu"il y ait détérioration des caractéristiques de roulement des éléments. Ce but a été atteint grâce au fait que les éléments (11, 12; 15) disposés par paires, avec leurs surfaces de roulement (13) tournées l"une face à l"autre, sont reliés entre eux par l"intermédiaire d"un organe de torsion (14) qui est flexible et/ou relié dans le sens de roulement des éléments (11, 12) et qui présente une grande rigidité transversalement au sens de roulement.
