Abstract

L'invention concerne un mécanisme d'entraînement, en particulier pour essuie-glace. Ce mécanisme comprend un carter moteur 10, 11 et un carter de mécanisme d'entraînement 12. L'arbre du rotor 14 pénètre dans le carter 12 et comporte une denture de vis sans fin 16 engrenant avec une roue 13. L'arbre 14 tourillonne dans deux paliers à calotte sphérique 21, 22 disposés de part et d'autre de la denture et pouvant tourner autour d'un axe parallèle à l'axe de rotation de la roue 13 mais fixes dans la direction longitudinale. On évite ainsi tout coincement de l'arbre dans les paliers en cas de courbure de cet arbre sous la charge de sortie. L'invention s'applique aux mécanismes d'entraînement d'essuie-glace pour vehicule automobile.The invention relates to a drive mechanism, in particular for a windscreen wiper. This mechanism comprises a motor casing 10, 11 and a drive mechanism casing 12. The shaft of the rotor 14 enters the casing 12 and comprises a worm gear 16 meshing with a wheel 13. The shaft 14 is journaled. in two spherical cap bearings 21, 22 arranged on either side of the toothing and capable of rotating about an axis parallel to the axis of rotation of the wheel 13 but fixed in the longitudinal direction. This prevents any jamming of the shaft in the bearings in the event of bending of this shaft under the output load. The invention applies to windshield wiper drive mechanisms for a motor vehicle.
