AM 8. NOVEIBBER 1922ISSUED
ON NOVEMBER 8, 1922
Für den Support an Werkzeugmaschinen,For support on machine tools,
Pressen u. dgl. verwendet man zum Vorschub einen Schraubenspindelantrieb. Der Vorschub kann infolgedessen ein verhältnismäßig grober sein und wird von der Steigung des Gewindes abhängen. Eine zu feine Steigung kann man aber der Schraubenspindel nicht geben, weil die Gewindegänge alsdann einen zu geringen Widerstand bieten und bei starker Inanspruchnähme schnell abgenutzt werden.Presses and the like are used to feed a screw spindle drive. The feed As a result, it can be relatively coarse and depends on the pitch of the thread depend. However, the screw spindle cannot be given a pitch that is too fine because the threads then offer too little resistance and with high demands wear out quickly.
Nach der Erfindung soll dieser Schraubeuspindelantrieb auch für sehr geringe Vorscliubbewegungen dadurch verwendbar gemacht werden, daß die in bekannter Weis« an dem Schlitten drehbar gelagerte Schraubenmutter einerseits und die Schraiibenspindel anderseits durch Mitnehinerorgane mit einer kuppelbaren A'orgelcgwelle so in Verbindung gesetzt sind, dal.? bei eingerückter A'orgelegwelle die Mutter eine Eigendrehung in der Drehrichtung" der Spindel erhält, deren Größe durch das Übersetzungsverhältnis der Zahnräderübertragung bestimmt wird.According to the invention, this screw spindle drive This also makes it usable for very small pre-club movements that the screw nut rotatably mounted on the slide in a known manner on the one hand and the screw spindle on the other hand by means of Mitnehinerorgane with a detachable organ shaft so in connection are set as.? with the auxiliary shaft engaged the nut receives its own rotation in the direction of rotation "of the spindle, its size is determined by the gear ratio of the gear transmission.
Tn der beiliegenden Zeichnung ist der Errindungsgegenstand veranschaulicht, und zwar zeigt:The object of the invention is in the accompanying drawing illustrates, namely shows:
Abb. ι den Grundriß der Vorschubvorrichtung, Fig. Ι the plan of the feed device,
Abb. 2 den Grundriß einer andern Ausführungsform, Fig. 2 is the plan of another embodiment,
Abb. 3 bis 5 Einzelheiten dazu.
Das dargestellte Ausführungsbeispiel gibt beispielsweise den Schlitten eines Supports
\\ ieder. Die Schraubenspindel α ist in der
Wand des Supports b drehbar gelagert und steht in Eingriff mit einer Mutter c, welche
an dem Schlitten- eine solche Lagerung erhält, daß sie gedreht, aber nicht in der Längsrichtung
verschoben werden kann. Die Mutter ist mit einem Zahnradi/ verbunden, und auch
auf der Schraubenspindel ist ein Zahnrad c befestigt.Fig. 3 to 5 for details.
The illustrated embodiment shows, for example, the carriage of a support. The screw spindle α is rotatably mounted in the wall of the support b and is in engagement with a nut c, which receives such a bearing on the carriage that it can be rotated but not displaced in the longitudinal direction. The nut is connected to a toothed wheel /, and a toothed wheel c is also attached to the screw spindle.
Parallel zu der Schraubenspindel ist nun eine Vorgelegwelle f gelagert. Sie trägt die beiden Zahnräder g und h, von denen das erstere mit dem Zahnrad d der Mutter, das letztere mit dem Zahnrad e der Schraubenspindel in Eingriff steht. Das Zahnrad Ii ist lose drehbar auf der Vorgelegwellc f angebracht. Es ist aber mit einer Kupplung*- liälfte i versehen, welche durch Vermittlung des Muffes k, der auf der \Torgelegwelle /' längsverschiebbar, aber nicht drehbar angebracht ist, in oder außer Eingriff gebracht werden kann. A countershaft f is now mounted parallel to the screw spindle. It carries the two gears g and h, of which the former is in engagement with the gear d of the nut, the latter with the gear e of the screw spindle. The gear Ii is loosely rotatably mounted on the countershaft c f . However, it is with a clutch * - i liälfte provided that k through the intermediary of Muffes, the orgelegwelle on the \ T / 'longitudinally displaceable, but not rotatably mounted, can be brought into or out of engagement.
Besteht dieser Eingriff (Abb. 1), dann wird die Drehbewegung der Schraubenspindel a durch Vermittlung1 des Zahnrades e und des Zahnrades /; auf den Kupplungsmuff k und auf diesen durch die Vorgelegwelle f übertragen, deren Drehbewegung nunmehr durch die Zahnräder g, d der Mutter e mitgeteilt wird. Die !Mutter c dreht sich alsdann in dem Sinne der Schraubenspindel. Würde die Übersetzung zwischen den Rädern α und Jv und 6g g und d wie 1 :1 gewählt, so würde die Drc-If this engagement (Fig. 1), then the rotary movement of the screw spindle a through the intermediary of 1 of the gear e and the gear /; transmitted to the coupling sleeve k and to this through the countershaft f , the rotational movement of which is now communicated to the nut e by the gears g, d. The! Nut c then rotates in the direction of the screw spindle. If the ratio between the gears α and Jv and 6g g and d were chosen to be 1: 1, the drive
