Title (EN) SPINDLE DRIVE
(FR) COMMANDE DE BROCHES
Abstract:
(EN) In order to achieve a compact spindle drive which is also lightweight and consisting of few components, and where the drive motor (8) is mounted in a stationary manner in relation to the spindle drive, the spindle drive according to the invention is configured with two sets of bevel gears comprising a first larger pair of gears (11, 13) and a second smaller pair of gears (12, 14). The spindles (15, 17) can hereby be mounted in star formation in the housing and alternately enter into engagement with the first gear (11) and the second gear (12), and thus alternately rotate the one way and the other way. At the same time, all of the spindles (15, 17) are suspended in the same plane, whereby a very uniform machining operation is achieved. Finally, the housing can be provided with a turning motor (21), which via a pinion (2, 19) can revolve the housing (1) at the same time that the spindles rotate.
(FR) Une commande de broches compacte, légère, constituée par un petit nombre d'éléments et dans laquelle le moteur d'entraînement (8) est monté de façon fixe par rapport à ladite commande de broches, est conçue d'après l'invention, avec deux jeux d'engrenages coniques comprenant une première paire d'engrenages de dimension supérieure (11, 13) et une deuxième paire d'engrenages de dimension inférieure (12, 14). On peut, de ce fait, monter les broches (15, 17) en étoile dans le carter, et lesdites broches venant alternativement en prise avec le premier engrenage (11) et le deuxième engrenage (12), tournent ainsi alternativement dans l'un et l'autre sens. De plus, toutes les broches (15 17) sont en suspension dans le même plan et réalisent, de ce fait, un usinage très uniforme. Enfin, le carter peut être pourvu d'un moteur rotatif (21) qui imprime au carter (1) une rotation simultanée à celle des broches, par l'intermédiaire d'un pignon (2, 19).
