Abstract

La présente invention concerne l'amélioration d'un appareil d'entraînement par friction rotative par vis à billes dans une machine de soudage par friction. L'appareil se caractérise en ce qu'un moteur est directement connecté à une vis à billes via un accouplement, et un écrou est monté sur un palier de butée à ajustement glissant avec le palier. Le palier de butée ainsi qu'un collier de serrage sont montés sur une table mobile par glissement. En outre, la vis à billes est fixée avec le socle-moteur par des coussinets, et l'extrémité avant du palier de butée est fixée avec des mandrins. Les avantages de l'invention sont les suivants: une construction simple, facile à réaliser et des coûts réduits. Le remplacement d'un bélier hydraulique par une servocommande peut assurer la commande précise de la force axiale, de la vitesse de réaction et du déplacement vers l'avant de la force. Par conséquent, l'invention peut réaliser une commande de la vitesse en boucle fermée, une commande de couple en boucle fermée et une commande de déplacement en boucle fermée dans le moteur, permettant une précision supérieure et une meilleure qualité de soudage par friction.
