Title (EN) DEVICE FOR THE COMPENSATION OF THE ROTATION TORQUE
(FR) DISPOSITIF POUR LA COMPENSATION DU COUPLE DE ROTATION
Abstract: front page image
(EN)The device for compensation of the rotation torque which is created during rocking of a body (1) mounted on a fixed shaft (5), comprises a stator part (4) and a rotor part (6) connected together on the fixed shaft. Between the stator part (4) and the rotor part (6) at least one spring (23, 24) acts with a return force opposite to the rotation torque, thereby effecting the transmission of the rotation torque to at least one spring by at least one lever arm, of which the effective length and/or of which the effective displacement component resulting from the torque change varies in the direction of the spring (23, 24). The device is particularly appropriate for a jointed head of a camera (11) or lighting apparatus.
(FR)Le dispositif pour la compensation du couple de rotation qui nait lors du basculement d"un corps (1) monte sur un axe fixe (5), comprend une partie stator (4) et une partie rotor (6) liees ensemble sur l"axe fixe. Entre la partie stator (4) et la partie rotor (6) agit au moins un ressort (23, 24) avec une force de rappel opposee au couple de rotation, par cela est realisee la transmission du couple de rotation a au moins un ressort par au moins un bras de levier, dont la longueur effective et/ou dont la composante effective de deplacement resultant du changement de couple varie dans la direction du ressort (23, 24). Le dispositif convient en particulier pour une tete d"articulation d"une camera (11) ou appareil d"eclairage.
