Abstract

Machine à coudre. Un mécanisme à la Cardan portant un dispositif à pignon 22, 24 en porte à faux transmet un travail à un organe de travail 58 pouvant se déplacer alternativement le long de son axe longitudinal. Le mécanisme est équilibré par rapport aux vecteurs de charge et plus généralement par rapport au moment. L'arbre d'entraînement principal 14 est équilibré à la fois par rapport aux vecteurs de c arge et au moment. Equilibrage de l'ensemble d'entraînement du mécanisme porte-aiguille d'une machine à coudre industrielle.Sewing machine. A Cardan mechanism carrying a cantilevered pinion device 22, 24 transmits work to a working member 58 which can move alternately along its longitudinal axis. The mechanism is balanced with respect to the load vectors and more generally with respect to the moment. The main drive shaft 14 is balanced with respect to both the arge vectors and the moment. Balancing of the drive assembly of the needle holder mechanism of an industrial sewing machine.
