Description

Die Erfindung betrifft einen Antrieb für eine Seiltrommel eines Hebezeuges gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a drive for a cable drum of a hoist according to the preamble of claim 1.

Aus der DE 196 33 832 C2 ist ein Seilzug mit einem Antrieb für eine Seiltrommel bekannt, die von einem Antriebsmotor angetrieben wird, dem ein Getriebe nachgeschaltet ist. Das Getriebe ist über eine Abtriebswelle mit der Seiltrommel verbunden, wobei die Abtriebswelle an ihrem der Seiltrommel zugewandten freien Ende einen Flansch trägt, der an der Stirnseite der Seiltrommel lösbar befestigt ist. Der Flansch wird hierzu in einen Aufnahmesitz eingesteckt und mittels einer Anzahl von Schrauben mit der Seiltrommel verschraubt, die radial zur Seiltrommel verlaufen. Die Abtriebswelle mit dem Flansch ist einstückig ausgebildet. Der einen Rahmen aufweisende Antrieb ist über eine fest mit dem Rahmen verbundene Platte am Getriebe festgeschraubt, und zwar auf der Seite, die der Seiltrommel zugewandt ist.DE 196 33 832 C2 describes a cable pull with a drive for a cable drum known, which is driven by a drive motor, which is a transmission is connected downstream. The gearbox is connected to the cable drum via an output shaft connected, the output shaft on its free facing the cable drum End carries a flange that is releasably attached to the front of the rope drum. The For this purpose, the flange is inserted into a receiving seat and by means of a number of Screws screwed to the cable drum, which run radially to the cable drum. The Output shaft with the flange is formed in one piece. The one frame having drive is on a plate firmly connected to the frame Screwed gearbox, on the side facing the cable drum.

Nachteilig ist bei diesem Antrieb, dass bei Belastung auftretende Verformungen des Rahmens zu Taumelbewegungen der Abtriebswelle bezogen auf die Seiltrommellängsachse führen, was mit unerwünschten Beanspruchungen der Seiltrommel, des Getriebes und der Trommellagerung verbunden ist.The disadvantage of this drive is that deformations of the Frame to wobble the output shaft based on the Lead rope longitudinal axis, which with undesirable stresses Cable drum, the gear and the drum bearing is connected.

Die Aufgabe der Erfindung ist es, bei auf einem Rahmen angeordnetem Antrieb mit Seiltrommel die Zusatzbeanspruchungen aufgrund von Taumelbewegungen zu vermeiden.The object of the invention is with a drive arranged on a frame with Rope drum to the additional stresses due to wobble movements avoid.

Die Lösung dieser Aufgabe ist durch die im Anspruch 1 angegebenen Merkmale gegeben. Durch die kennzeichnenden Merkmale der Unteransprüche ist der Antrieb in vorteilhafter Weise weiter ausgestaltet.This object is achieved by the features specified in claim 1 given. Due to the characterizing features of the subclaims, the drive is in advantageously further developed.

Die Lösung sieht vor, dass bei einem biegesteifen Rahmen das Getriebegehäuse lediglich auf der der Seiltrommel zugewandten Seite am Rahmen frei aufliegend abgestützt sowie zusätzlich über eine Drehmomentstütze mit dem Rahmen drehfest verbunden ist. Das Getriebe ist also nicht mehr starr mit dem Rahmen verbunden. Auf diese Weise wird erreicht, dass Verformungen des Rahmens bei großen Lasten, die auch bei biegesteifen Rahmen auftreten, keine Taumelbewegungen der Abtriebswelle bezogen auf die Seiltrommellängsachse führen, insbesondere im Bereich der Verbindung von Abtriebswelle und Seiltrommel. Damit sind diese unkalkulierbaren Beanspruchungen beseitigt. Als zusätzlicher Vorteil ergibt sich eine kurzbauende Ausführung des Antriebs.The solution provides that the gear housing in a rigid frame only lying freely on the side facing the rope drum on the frame supported as well as non-rotatably with the frame via a torque arm connected is. The gearbox is no longer rigidly connected to the frame. On This ensures that the frame is deformed at high loads occur even with rigid frames, no wobbling of the output shaft lead with respect to the cable drum longitudinal axis, especially in the area of Connection of output shaft and rope drum. This makes them incalculable Strains removed. An additional advantage is a short construction Execution of the drive.

Mit der Erfindung wird weiter vorgeschlagen, dass der Flansch an der Stirnseite der Seiltrommel mittels parallel zur Abtriebswelle und zur Seiltrommellängsachse verlaufender Schrauben an der Seiltrommel befestigt ist. Diese Art der Befestigung hat den Vorteil, dass bei einem Antrieb auf der Grundlage eines Baukastensystems an jedes Getriebe zumindest zwei unterschiedlich dimensionierte Seiltrommeln anbaubar sind. Dies senkt die Zahl der bereitzustellenden Getriebe erheblich.With the invention it is further proposed that the flange on the front side of the Cable drum by means of parallel to the output shaft and the cable drum longitudinal axis extending screws is attached to the cable drum. This type of attachment has the advantage that with a drive based on a modular system each gearbox can be fitted with at least two differently dimensioned cable drums are. This significantly reduces the number of gearboxes to be made available.

Eine sehr stabile und gleichmäßige Verbindung zwischen Flansch und Seiltrommel wird erzielt, wenn alle Schrauben den gleichen radialen Abstand von der Seiltrommellängsachse aufweisen und im gleichen Winkelabstand voneinander angeordnet sind.A very stable and even connection between the flange and the cable drum is achieved when all screws are the same radial distance from the Have rope drum longitudinal axis and at the same angular distance from each other are arranged.

Konstruktiv vereinfachend ist es, wenn der Flansch unter Zwischenschaltung eines an der Seiltrommel angeschweißten Zwischenrings an der Seiltrommel angeschraubt ist. Dieser Zwischenring ist insbesondere bei einem Baukastensystem von Vorteil, da die Bohrung für die Schrauben vor dem Anschweißen an die Seiltrommel angepasst an den jeweiligen Flanschdurchmesser hergestellt werden können.It is structurally simpler if the flange is connected with an interposed one the intermediate ring welded on the rope drum is screwed onto the rope drum. This intermediate ring is particularly advantageous in a modular system because the Adjusted the hole for the screws before welding to the cable drum the respective flange diameter can be manufactured.

Zweckmäßigerweise dient der Zwischenring gleichzeitig als seitliche Seilablaufsicherung, wozu er über das auf der Seiltrommel aufgewickelte Seil hinaus radial nach außen ragt.The intermediate ring expediently also serves as a lateral ring Rope drainage protection, for which it extends beyond the rope wound on the rope drum protrudes radially outwards.

Um ein Abheben des Getriebegehäuses auf der am Rahmen abgestützten Seite zu vermeiden, ist eine Abhebsicherung in Form eines gebogenen Bügels vorgesehen, so dass nur innerhalb eines vorgegebenen Spiels ein Abheben von der Abstützung möglich ist. To lift off the gearbox on the side supported on the frame avoid, a lift-off protection in the form of a curved bracket is provided, so that only within a given game a lift off the support is possible.

Fig. 1 zeigt einen Antrieb 1 für eine Seiltrommel 2, z.B. eines Hebezeugs. Bei dem Hebezeug handelt es sich um einen Seilzug, dessen Seil 3 auf die Seiltrommel 2 auf- und abwickelbar ist. Der Antrieb 1 umfasst ein Getriebe 4, das von einem angeflanschten Antriebsmotor 5 (s. Fig. 2) angetrieben wird. Das Getriebe 4 weist zur Änderung des Übersetzungsverhältnisses mehrere miteinander kämmende Zahnräder 6 auf. Eines der Zahnräder 6 sitzt drehfest auf einer Abtriebswelle 7, die mit der Seiltrommel 2 drehfest verbunden ist. Auf der dem Getriebe 4 gegenüberliegende Seite ist die Seiltrommel 2 über ein Stehlager 8 an einem Rahmen 9 frei drehbar abgestützt.Fig. 1 shows a drive 1 for a cable drum 2, e.g. of a hoist. In which Hoist is a cable pull, the cable 3 on the cable drum 2 and can be developed. The drive 1 comprises a gear 4, which by a flanged drive motor 5 (see FIG. 2) is driven. The gear 4 points to Changing the gear ratio of several meshing gears 6 on. One of the gears 6 is non-rotatably on an output shaft 7, which with the Cable drum 2 is rotatably connected. On the opposite of the gear 4 On the side, the cable drum 2 can be freely rotated via a pillow block 8 on a frame 9 supported.

Wie Fig. 1 erkennen lässt, erfolgt die Drehlagerung der Seiltrommel 2 auf der Getriebeseite über Getriebedrehlager 10, 11. Zur Abstützung des Getriebes 4 und der Seiltrommel 2 am Rahmen 9 liegt das Getriebegehäuse 12 mit seinem Getriebedeckel 13 über eine Nabenlagerstütze 14 am Rahmen 9 auf. Der Getriebedeckel 13 ist hierbei frei aufliegend am Rahmen 9 abgestützt. Ansonsten ist das Getriebe 4 nur noch über eine Drehmomentenstütze 15 mit dem Rahmen 9 drehfest verbunden.As can be seen in FIG. 1, the cable drum 2 is rotatably mounted on the Gearbox side via gearbox pivot bearing 10, 11. To support the gearbox 4 and Cable drum 2 on the frame 9 is the gear housing 12 with its gear cover 13 on a hub bearing support 14 on the frame 9. The gear cover 13 is here supported freely on the frame 9. Otherwise, the transmission 4 is only over a torque arm 15 is rotatably connected to the frame 9.

Fig. 2 zeigt den Antrieb 1 mit der Seiltrommel 2 von oben gesehen. Wie Fig. 2 zeigt, ist der Antriebsmotor 5 an das Getriebe 4 angeflanscht. Fig. 2 shows the drive 1 with the cable drum 2 seen from above. 2 shows the drive motor 5 flanged to the transmission 4.

Fig. 3 zeigt weitere Einzelheiten des Antriebs gemäß Fig. 1 in einer teilgeschnittenen Darstellung. So ist Fig. 3 entnehmbar, dass die Abtriebswelle 7 einen Flansch 7a trägt, der unter Zwischenschaltung eines an der Seiltrommel 2 angeschweißten Zwischenrings 16 an der Seiltrommel 2 mittels Schrauben 17 angeschraubt ist. Der Zwischenring 16 ragt mit seinem Teil 16a über das auf der Seiltrommel 2 aufgewickelte Seil 3 radial nach außen, wobei es als seitliche Seilablaufsicherung dient. Die Schrauben 17 verlaufen parallel zur Abtriebswelle 7 und zur Seiltrommellängsachse 18. Die Schrauben 17 sind im gleichen radialen Abstand von der Seiltrommellängsachse 18 und im gleichen Winkelabstand zueinander angeordnet.Fig. 3 shows further details of the drive of FIG. 1 in a partially sectioned Presentation. 3 that the output shaft 7 carries a flange 7a, the with the interposition of a welded to the cable drum 2 Intermediate ring 16 is screwed to the cable drum 2 by means of screws 17. The The intermediate ring 16 projects with its part 16a over that wound on the cable drum 2 Rope 3 radially outwards, it serves as a lateral rope drainage protection. The Screws 17 run parallel to the output shaft 7 and the cable drum longitudinal axis 18. The screws 17 are at the same radial distance from the Cable drum longitudinal axis 18 and arranged at the same angular distance from each other.

Fig. 4 zeigt den Antrieb gemäß Fig. 3 in Richtung der Sichtlinie IV - IV gesehen. Zur Vermeidung von einem Abheben des Getriebes 4 von der Nabenlagerstütze 14 bei stoßartiger Belastung des Antriebs 1 ist ein gebogener Bügel 19 vorgesehen, der als Abhebsicherung wirksam ist. Der Bügel 19 belässt einen Ringspalt zwischen dem Getriebedeckel 13 und seiner Innenfläche 20, so dass bei den üblichen Verformungen des starren Rahmens 9 bei großen Lasten ein Ausgleich an der Nabenlagerstütze 14 erfolgen kann. Dieser selbsttätige Ausgleich führt dazu, dass im Bereich der Nabenlagerstütze 14 keine Taumelbewegungen auftreten, d.h. der Abtriebswelle 7 bezogen auf die Seiltrommellängsachse 18. FIG. 4 shows the drive according to FIG. 3 seen in the direction of line of sight IV-IV. to Avoidance of lifting the gear 4 from the hub bearing support 14 shock-like loading of the drive 1, a curved bracket 19 is provided, which as Withdrawal protection is effective. The bracket 19 leaves an annular gap between the Gear cover 13 and its inner surface 20, so that the usual deformations the rigid frame 9 compensates for large loads on the hub bearing support 14th can be done. This automatic compensation means that in the area of Hub bearing support 14 no wobble, i.e. the output shaft 7 related to the cable drum longitudinal axis 18.
