Description
362S15362S15
Gegenstand der Erfindung ist ein Zugspindelantrieb für Drehbänke, bei dem die Zugspindel entweder von der Leitspindel aus oder besonders, unter Vorschaltung eines Wechselgetriebes, angetrieben wird. Derartige Zugspindelantriebe sind für Drehbänke bekannt. Diesen bekannten Antrieben gegenüber besteht die Erfindung darin, daß auf der Zugspindel umdreh-, aber achsialverschiebbar ein Zahnrad oder Zahnräderpaar angeordnet ist, das entweder mit einem auf der Leitspindel sitzenden Rade oder mit einem auf der Zugspindel lose drehbar angeordneten Stufenrädersatze oder mit einem Rade einer Vorgelegewelle zum Eingriff kommt, deren anderes Rad mit einem Rade des Stufenrädersatzes im Eingriff steht.The invention relates to a spindle drive for lathes, in which the Pull spindle either from the lead screw or specially, with an upstream one Gearbox, is driven. Such spindle drives are for lathes known. In relation to these known drives, the invention consists in that A gear wheel or gear wheel pair can be rotated but axially displaced on the tension spindle is arranged, either with a wheel sitting on the lead screw or with one on the tension spindle loosely rotatably arranged step gear sets or with one Gear of a countershaft comes into engagement, the other gear is in engagement with a gear of the stepped gear set.
Auf der Zeichnung ist der Zugspindelantrieb in
ao Abb. ι im Längsschnitt, inThe drawing shows the spindle drive in
ao Fig. ι in longitudinal section, in
Abb. 2 in Seitenansicht dargestellt. Abb. 3 und 4 veranschaulichen den Antrieb in verschiedenen Stellungen.Fig. 2 shown in side view. Fig. 3 and 4 illustrate the drive in different positions.
Der Antrieb der Zugspindel 1 erfolgt in bekannter Weise durch die Stufenräder α
bis h unabhängig von der Leitspindel 2. Dabei laufen die Räder e bis h lose auf der Zugspindel
i. Damit man den Vorschub verdoppeln kann, ist noch das Rädenvorgelege
i, k, I angeordnet. Die Räder/ und m sind
fest verbunden und verschiebbar auf der Zugspindel 1 mittels Keiles befestigt, wobei
das Rad m seinen Antrieb durch Rad η von
der Leitspindel aus erhält.
Die Arbeitsweise ist folgende:The drive of the tension spindle 1 takes place in a known manner by the step wheels α to h independently of the lead screw 2. The wheels e to h run loosely on the tension spindle i. So that the feed can be doubled, the gear reduction gear i, k, I is also arranged. The wheels / and m are firmly connected and slidably attached to the tension spindle 1 by means of wedges, the wheel m receiving its drive from the lead screw by wheel η.
The way it works is as follows:
Beim normalen Lang- oder Plandrehen durch die Zugspindel 1 werden die Räder a, h, c, d wechselseitig mit der sie tragenden Welle gekuppelt. Soll der Vorschub ein langsamer sein, so wird die Bewegung der Räder e, f, g und h, wie aus Abb. 1 ersichtlich, durch das Rädervorgelege i, k auf Rad I übertragen. Zur Erzielung schneller Vorschübe wird das Rad I nach rechts verschoben und unmittelbar mit dem Räderblock e> f> Si h verkuppelt, wie nach Abb. 4. Zur Erzielung beim Drehen sich nötig machender außergewöhnlicher Vorschübe werden Wechselräder O1 p, q angesteckt; durch Verschieben des Rades I1 m auf der Zugspindel nach links wird Rad m mit Rad η in Eingriff gebracht, so daß die Bewegung unmittelbar von der Leitspindel 2 auf die Zugspindel 1 übertragen wird. Dabei laufen· die Räder α bis k leer. Zum Verschieben des Doppelrades I1 nv dient der Hebel r. Auch kann man Rad η so anbringen, daß es unmittelbar in Rad I eingreifen kann, wenn die Übersetzungsverhältnisse solches erfordern. Um ein leeres Mitlaufen der Leitspindel zu vermeiden, wenn die Zugspindel durch Wechselräder getrieben wird, kann man die Leitspindel geteilt ausführen und durch Kupplung mit Radw verbinden.During normal long or face turning by the tension spindle 1, the wheels a, h, c, d are alternately coupled to the shaft that carries them. If the advance is to be slower, the movement of the wheels e, f, g and h is transferred to wheel I by the gear reduction i, k , as can be seen in FIG. To achieve faster feed rates, wheel I is shifted to the right and immediately coupled to the wheel block e >f> Si h , as shown in Fig. 4. To achieve extraordinary feed rates that become necessary when turning, change gears O 1 p, q are attached; by moving the wheel I 1 m on the tension spindle to the left, wheel m is brought into engagement with wheel η , so that the movement is transmitted directly from the lead screw 2 to the tension spindle 1. The wheels α to k run idle. The lever r is used to move the double wheel I 1 nv. Wheel η can also be attached in such a way that it can intervene directly in wheel I if the gear ratios require it. In order to prevent the lead screw from idling when the pull screw is driven by change gears, the lead screw can be divided and connected to the wheel by a coupling.
