Title
(EN) HEADER OF A HARVESTER
(FR) BEC CUEILLEUR POUR RÉCOLTEUSE
Abstract
(EN) A header (10) is described for a harvester having a cutter and an auger powered from a PTO shaft of the harvester by means of respective transmissions. Each transmission includes drive and driven sheaves (18, 22) or sprockets coupled to one another by a continuous drive belt (20) or chain. In the invention, at least one of the drive and driven sheaves (18, 22) or sprockets of the transmissions driving the cutter and the auger is coupled to an associated shaft by means of a torsional vibration compensator (60), such as a friction damper.
(FR) La présente invention concerne un bec cueilleur (10) pour récolteuse comportant une tête de coupe et une vis sans fin animées par l'arbre de prise de force de la récolteuse par l'intermédiaire de leurs propres transmissions. Chaque transmission comprend des poulies d'entraînement et des poulies entraînées (18, 22) ou des pignons couplés les uns aux autres par une courroie d'entraînement sans fin (20) ou une chaîne. Dans l'invention, au moins l'une des poulies d'entraînement ou des poulies entraînées (18, 22) ou l'un des pignons des transmissions animant la tête de coupe et la vis sans fin est couplé à un arbre associé, par l'intermédiaire d'un dispositif compensateur des vibrations de torsion (60), tel qu'un amortisseur à friction.
