Abstract

a. Commande de rotation pour la broche principale d'une machine-outil. b. Commande caractérisée en ce que, sur un arbre de commande sont montées deux blocs de roues dentées baladeuses qu'on peut faire coulisser au moyen d'organes d'embrayage en liaison active avec deux blocs de roues dentées correspondants fixés avec possibilité de rotation sur un arbre intermédiaire, cependant que les rapports de vitesse entre les différentes paires de roues dentées pouvant être mises en prise l'une avec l'autre sont différents et chacun des deux blocs de roues dentées montés sur l'arbre intermédiaire peut être couplé au choix avec l'arbre intermédiaire au moyen chacun d'un accouplement, l'arbre intermédiaire étant en liaison avec la broche principale par l'intermédiaire des roues dentées. c. L'invention s'applique notamment aux tours de décolletage.at. Rotation control for the main spindle of a machine tool. b. Control characterized in that, on a control shaft are mounted two blocks of wandering toothed wheels which can be slid by means of clutch members in active connection with two corresponding toothed wheel blocks fixed with the possibility of rotation on a countershaft, however, the speed ratios between the different pairs of gear wheels that can be engaged with each other are different and each of the two gear blocks mounted on the countershaft can be coupled as desired with the intermediate shaft each by means of a coupling, the intermediate shaft being in connection with the main spindle via the toothed wheels. vs. The invention applies in particular to turning lathes.
