Abstract

In a rope hoist (9), the output shaft (37) of the gearing (19) is provided in one piece with an end plate (57). This end plate (57) is designed in such a way that it can be inserted into a locating seat (66) of the tubular rope drum (17). The end plate (57) is screwed in the rope drum (17) by means of radial fitting screws (72). There is also a recess (67) at the other end of the rope drum (17), and a similar end plate (75) can be fastened in this recess (67) in the same manner. This other end plate carries a bearing journal (76). On account of this arrangement, the manufacture of the rope drum (17) and the entire assembly are simplified, complicated shaft joints between the output shaft (37) and the rope drum (17) being dispensed with on account of the mounting of the rope drum (17) by means of the output shaft (37) of the gearing (19). In addition, the rope hoist (9) may be split up into comparatively small subassemblies for dispatch.

Description

Bei Seilzügen wird die Seiltrommel von einem Elektromotor über ein dazwischengeschaltetes Untersetzungsgetriebe angetrieben. Die Schwierigkeit besteht dabei darin, die Seiltrommel so zu lagern, daß Fluchtungsfehler zwischen den verschiedenen Lagern für die Seiltrommel und das Getriebe möglichst vermieden werden, um Verspannungen und daraus resultierende erhöhte Abnutzungen der Lager zu vermeiden. Dies ist deswegen nicht unproblematisch, weil die Seiltrommel eine beträchtliche Länge und eine beträchtliche Masse hat, so daß die Fluchtung der an den Enden vorhandenen Lager nicht ohne weiteres mit der geforderten Präzision hergestellt werden kann.In rope hoists, the rope drum is powered by an electric motor via an intermediate reduction gear driven. The difficulty is there in storing the rope drum so that misalignment between the different bearings for the cable drum and the transmission should be avoided as much as possible to avoid tension and the resulting increased wear on the bearings avoid. This is not without problems because the rope drum is of considerable length and considerable Has mass, so that the alignment of the Existing bearings do not end easily with the required Precision can be made.

Ein weiteres Kriterium ist die Anzahl der Bauteile, die zum Antrieb und zur Lagerung erforderlich ist. Hierbei ist ein nicht unerhebliches Augenmerk auf die Art der Lagerung der Seiltrommel zu richten, die aus Gewichtsgründen rohrförmig ist.Another criterion is the number of components which is required for drive and storage. Here is a not inconsiderable focus on the type of Storage of the cable drum to be addressed for weight reasons is tubular.

Aus der DE 12 05 247 B ist ein Seilzug bekannt, dessen Seiltrommel an einem Ende eine eingeschweißte konische Flanschscheibe enthält, in deren innerer Bohrung ein rohrförmiger Lagerzapfen eingeschweißt ist. Der Lagerzapfen bildet seinerseits die Ausgangswelle eines Getriebes, auf der drehfest das Ausgangszahnrad des Untersetzungsgetriebes sitzt. Zwischen dem Ausgangszahnrad und der Seiltrommel befindet sich ein Wälzlager, das in einem in dem Rahmen des Seilzugs angeordneten Lagersitz untergebracht ist.A cable pull is known from DE 12 05 247 B, whose rope drum is welded at one end contains conical flange washer, in its inner bore a tubular bearing journal is welded in. The bearing journal in turn forms the output shaft of a gearbox, on the rotatably the output gear of the reduction gear sits. Between the output gear and the Rope drum is a roller bearing, which in a the bearing seat arranged in the frame of the cable pull is.

Weil bei dieser Konstruktion der Lagerzapfen, der gleichzeitig Ausgangswelle des Getriebes ist, von der Seiltrommel nicht trennbar ist, ist der Zusammenbau des Seilzugs ausgesprochen kompliziert. Außerdem ist die Herstellung der Seiltrommel aufwendig, denn es muß zunächst die mit dem Lagerzapfen verschweißte Flanschscheibe ihrerseits in die Seiltrommel eingeschweißt werden. Erst danach kann der Lagerzapfen spangebend bearbeitet werden, um die Lagersitze zu erzeugen. Ein Herstellen der Lagersitze vor dem Einschweißen würde auf keinen Fall die erforderliche Präzision erbringen. Es wäre unvermeidbar, daß die Lagersitze des Lagerzapfens zumindest gegenüber der Achse der Seiltrommel schief stehen, was enorme Verspannungen im Getriebe hervorrufen würde.Because with this construction the bearing journal, the is at the same time the output shaft of the gearbox Rope drum is not separable, is the assembly of the Cable pull extremely complicated. Besides, that is Manufacturing the rope drum is expensive, because it must first the flange disc welded to the bearing journal are in turn welded into the rope drum. First then the bearing journal can be machined, to create the bearing seats. Manufacturing the bearing seats under no circumstances would the provide the required precision. It would be inevitable that the bearing seats of the journal at least opposite the axis of the rope drum are crooked, causing enormous tension would cause in the transmission.

Die DE 438 528 C zeigt einen Seilzug, bei dem die Seiltrommel mit einer eingegossenen Nabe versehen ist, die sich über Speichen an der Trommelwand abstützt. Koaxial zu dieser Nabe ist die Seiltrommel mit einer Ausdrehung versehen, in die ein becherförmiges Hohlrad eingesetzt ist. Das Hohlrad geht auf der Seite der Trommelnabe in einen scheibenförmigen Boden über, aus dem ein rohrförmiger Ansatz heraussteht. Nabe und rohrförmiger Ansatz sind über Sitze miteinander verbunden, so daß die Lagerung der Trommel über den rohrförmigen Fortsatz der Hohlradanordnung und der Nabe erfolgt.DE 438 528 C shows a cable pull in which the Rope drum is provided with a cast-in hub that is supported by spokes on the drum wall. Coaxial to this hub is the rope drum with one turn provided, into which a cup-shaped ring gear is inserted is. The ring gear goes in on the side of the drum hub a disc-shaped bottom from which a tubular Approach stands out. Hub and tubular neck are connected via seats so that the storage of the Drum over the tubular extension of the ring gear assembly and the hub is done.

Bei dieser Anordnung ist somit die Getriebeausgangswelle, die ein mit dem Hohlrad kämmendes Ritzel trägt, von der Trommellagerung getrennt.With this arrangement, the transmission output shaft is which carries a pinion meshing with the ring gear, from the drum storage separately.

Da die Befestigung des Hohlrads mit Hilfe von Schrauben erfolgt, die in die Stirnseite der Seiltrommel eingeschraubt sind, muß die Seiltrommel verhältnismäßig dickwandig sein, was das Gewicht der Seiltrommel unnötig erhöht. Außerdem ist die Montage und die Herstellung der Seiltrommel bei dieser bekannten Lösung aufwendig.Since the attachment of the ring gear with the help of screws done, which is screwed into the front of the rope drum are, the rope drum must be relatively thick-walled be what the weight of the rope drum unnecessary elevated. In addition, the assembly and manufacture of the Rope drum is expensive in this known solution.

Die DE 24 48 357 A1 zeigt einen Seilzug, bei dem im Inneren der Seiltrommel ein mehrstufiges Getriebe angeordnet ist. Den Abschluß des Getriebes bildet an der Stirnseite der Seiltrommel ein Lagerring, der in die Seiltrommel eingesteckt ist und mit Hilfe von Paßstiften, die radial durch die Trommel hindurchführen, drehgesichert ist. Der Ring ist mittels eines Kugellagers auf einem Gehäuseansatz des Getriebegehäuses abgelagert. Fluchtungsfehler dieses Lagersitzes, bezogen auf das Getriebe im Inneren der Seiltrommel, belasten entweder den Lagersitz oder führen zu Fehlstellungen der Zahnräder im Inneren der Seiltrommel und damit zu einer erhöhten Abnutzung.DE 24 48 357 A1 shows a cable pull in which A multi-stage gear is arranged inside the cable drum is. The end of the gearbox is on the front the rope drum is a bearing ring that fits into the rope drum is inserted and with the help of dowel pins that Lead radially through the drum, secured against rotation is. The ring is on a ball bearing The housing shoulder of the gearbox housing is deposited. Misalignment this bearing seat, based on the gearbox in Inside the rope drum, either load the bearing seat or lead to misalignment of the gears inside the Rope drum and thus increased wear.

Ausgehend hiervon ist es Aufgabe der Erfindung, einen Seilzug zu schaffen, bei dem die Seiltrommel mit einem geringen Gewicht leicht hergestellt werden kann und bei dem keine getrennten Lagerstellen für die Ausgangswelle und die Trommellagerung erforderlich sind.Based on this, it is an object of the invention to To create a cable, in which the cable drum with a light weight can be easily manufactured and at which no separate bearings for the output shaft and drum storage are required.

Diese Aufgabe wird erfindungsgemäß durch den Seilzug mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by the cable solved with the features of claim 1.

Bei der neuen Lösung wird von dem Umstand Gebrauch gemacht, daß die Seiltrommel ohnehin drehend bearbeitet werden muß. Bei dieser Gelegenheit können an beiden Stirnenden Aufnahmesitze erzeugt werden, die koaxial zur Außenseite der Seiltrommel sind. Diese Aufnahmesitze dienen als Aufnahmen von Stirnplatten, die Lagerzapfen tragen. Dadurch ist eine weitgehende Fluchtung sowohl der Achsen der Lagerzapfen untereinander als auch mit der Achse der Seiltrommel gewährleistet. Einer der Lagerzapfen ist gleichzeitig so gestaltet, daß er die Ausgangswelle des Untersetzungsgetriebes darstellt. Hierdurch wird die Lagerung der Ausgangswelle des Getriebes gleichzeitig zur Lagerung der Seiltrommel, was zusätzliche Lager auf der Getriebeseite und Ausgleichseinrichtungen in der Antriebswelle entbehrlich macht.This fact is used in the new solution made that the rope drum worked rotating anyway must become. On this occasion, both ends Recording seats are generated that are coaxial to the outside the rope drum. These seats serve as Images of end plates that carry trunnions. Thereby is an extensive alignment of both the axes of the Bearing journal with each other as well as with the axis of the Rope drum guaranteed. One of the journals is designed at the same time so that he the output shaft of the Reduction gear represents. This will make the Bearing of the output shaft of the gearbox at the same time Storage of the rope drum, which means additional bearings on the Gearbox side and compensation devices in the drive shaft makes dispensable.

Da die Stirnplatte lediglich in den Aufnahmesitz eingesteckt wird, ergibt sich eine stark vereinfachte Montage. Das Getriebe mit der Ausgangswelle und den Zahnrädern kann fertig montiert werden und stellt eine vergleichsweise leichte, werksseitig zusammengebaute Einheit dar. Hierbei behindert keine schwere und unhandliche Seiltrommel die Montage des Getriebes, das ohne weiteres ohne Seiltrommel auf Funktionsfähigkeit und ordnungsgemäßes Lagerspiel überprüft werden kann.Since the face plate is only in the receiving seat is plugged in, there is a greatly simplified Assembly. The gearbox with the output shaft and the gears can be assembled and represents a comparative light, factory assembled unit This does not hinder a heavy and unwieldy rope drum the assembly of the gearbox, which is easily done Rope drum on functionality and proper Bearing clearance can be checked.

Für den weiteren Zusammenbau genügt es, diese vormontierte Getriebeeinheit mit der daran sitzenden Stirnplatte für die Seiltrommel in letztere einzustecken und mit Hilfe der radial verlaufenden Befestigungsschrauben in der Seiltrommel zu sichern. Diese Art der Sicherung der Stirnplatte in der Trommel ermöglicht die Verwendung einer Seiltrommel, deren Wandstärke ausschließlich nach Belastungsgesichtspunkten durch das Seil bemessen ist und nicht wegen der Verwendung von in die Stirnseite eingedrehten Schrauben unnötig vergrößert ist. Ferner ist die Seiltrommel bei dem neuen Seilzug ein einfaches rohrförmiges Gebilde, an dem keine empfindlichen Lagerzapfen wegstehen, wie dies zum Teil beim Stand der Technik der Fall ist.For further assembly, it is sufficient to pre-assemble it Gear unit with the front plate attached to it for the cable drum to insert in the latter and with the help of the radial fastening screws in secure the rope drum. This kind of securing the End plate in the drum allows the use of a Rope drum, the wall thickness of which is based solely on load factors is measured by the rope and not because of the use of screwed into the face Screws is enlarged unnecessarily. Furthermore, the Rope drum in the new rope pull a simple tubular Structure on which no sensitive trunnions protrude, as is partly the case with the prior art is.

Die radial verlaufenden Befestigungsschrauben für die Stirnplatte haben außerdem den Vorteil der leichten Zugänglichkeit und sie erfordern keinen zusätzlichen Bauraum zwischen der Seiltrommel und der benachbarten Getriebegehäusewand.The radial fastening screws for the End plates also have the advantage of easy accessibility and they do not require additional space between the cable drum and the adjacent gear housing wall.

Der Aufnahmesitz ist vorzugsweise eine Ausdrehung, bestehend aus einer Zylinderfläche und einer Ringschulter. Wenn diese Ringschulter sich im Inneren der Seiltrommel befindet, ist sie gegen Beschädigungen während des Transportes optimal geschützt. Die Ringschulter bildet zusammen mit der Zylinderfläche eine sehr gute Möglichkeit, die Stirnplatte exakt zu zentrieren, um einen Taumel- und einen Radialschlag der Ausgangswelle bezogen auf die Trommelachse und den anderen Lagerzapfen zu vermeiden.The receiving seat is preferably a turn, consisting of a cylinder surface and a ring shoulder. If this ring shoulder is inside the rope drum is against damage during transport optimally protected. The ring shoulder forms together with the cylinder surface a very good way to Center the end plate exactly to a wobble and a radial runout of the output shaft based on the Avoid drum axis and the other journal.

Die Montage wird weiter vereinfacht, wenn das Ausgangszahnrad mit der Ausgangswelle profilverzahnt ist. Dadurch ist ein einfaches Aufstecken, das keine besonders große Montagekraft erfordert, möglich.Assembly is further simplified if the output gear is profiled with the output shaft. This makes it easy to attach, which is not special great assembly force required, possible.

Eine besonders robuste Konstruktion wird erhalten, wenn das Getriebegehäuse ein im wesentlichen einstückiges, hohles Formteil ist, bei dem die beiden Stirnwände und die Seitenwandanordnung einstückig miteinander verbunden sind, wobei in den Stirnwänden die erforderlichen Lagersitze untergebracht sind. Zwecks Montage ist im Bereich der Lagersitze für die Ausgangswelle in der Seitenwandanordnung eine Öffnung enthalten, durch die das auf der Ausgangswelle sitzende Ausgangszahnrad eingeführt werden kann. A particularly robust construction is obtained if the gear housing is a substantially one-piece, is a hollow molding in which the two end walls and the Side wall arrangement are integrally connected to one another, the required bearing seats in the end walls are accommodated. The purpose of assembly is in the area of Bearing seats for the output shaft in the side wall arrangement contain an opening through which that on the output shaft seated output gear can.

Der Antriebsmotor sitzt bei dem neuen Seilzug vorzugsweise außerhalb der Seiltrommel. Es können demzufolge Normmotoren verwendet werden und die Kühlung des Motors ist nicht durch die umgebende Seiltrommel und den Luftspalt zwischen Motor und Seiltrommel behindert.The drive motor is preferably seated in the new cable pull outside the rope drum. As a result, it can Standard motors are used and the cooling of the motor is not due to the surrounding rope drum and the air gap between the motor and the cable drum.

    • In Fig. 1 ist eine Katze 1 veranschaulicht, das dazu vorgesehen ist, längs einer Fahrschiene 2 zu laufen. Die Fahrschiene 2 besteht aus einem I-förmigen Träger mit einem Oberflansch 3, einem Unterflansch 4 und einem die beiden Flansche miteinander verbindenden geraden Steg 5. Auf der Oberseite des Unterflansches 4 läuft das Katzfahrwerk 1.In Fig. 1 a cat 1 is illustrated, this is provided to run along a rail 2. The Track 2 consists of an I-shaped support with an upper flange 3, a lower flange 4 and one straight web 5 connecting the two flanges. The trolley runs on the top of the lower flange 4 1.

    Zu den Hauptbestandteilen der Katze 1 gehören zwei parallel mit Abstand zueinander angeordnete Fahrwerkswangen 6 und 7, zwischen denen die Fahrschiene 2 verläuft und die über zwei zueinander parallele Verbindungssäulen 8 miteinander verbunden sind.The main components of Cat 1 include two Running gear cheeks arranged parallel and at a distance from each other 6 and 7, between which the running rail 2 runs and the two parallel connecting columns 8th are interconnected.

    Die Fahrwerkswange 6 umfaßt einen Seilzug 9, während die andere Fahrwerkswange 7 mit einem Fahrantriebsmotor 11 sowie einem Gegengewicht versehen ist.The chassis cheek 6 comprises a cable 9, while the other chassis cheek 7 with a travel drive motor 11 as well as a counterweight.

    Auf den einander zugekehrten Seiten der beiden Fahrwerkswangen 6 und 7 sind insgesamt vier Laufräder 12 drehbar gelagert, von denen die beiden dem Betrachter zugekehrten Laufräder 12 gemeinsam über den Fahrantriebsmotor 11 in Umdrehungen zu versetzen sind.On the mutually facing sides of the two chassis cheeks 6 and 7 are a total of four impellers 12 pivoted, the two of which are the viewer facing impellers 12 together via the drive motor 11 are to be rotated.

    Die Fahrwerkswange 6 wird von einem Rahmen 13 des Seilzugs 9 gebildet und zu ihr gehört ein in Richtung parallel zu der Fahrschiene 2 sich erstreckendes längliches Rahmenbasismittel 14, an dem die beiden Laufräder 12 drehbar gelagert sind, sowie zwei an dem Rahmenbasismittel 14 befestigte Rahmenkopfmittel 15 und 16. Die Rahmenkopfmittel 15 und 16 sind stabile Flanschplatten, die an dem Rahmenbasismittel 14 angeschraubt sind und parallel sowie im Abstand zueinander verlaufen. Zwischen den beiden Rahmenkopfmitteln 15 und 16 ist eine Seiltrommel 17 drehbar gelagert, die von einem Antriebsmotor 18 über ein Getriebe 19 angetrieben ist. Wie die Fig. 2 weiter erkennen läßt, ist das Getriebe 19 an dem Rahmenkopfmittel 15 angeschraubt, und zwar befindet es sich auf der von dem Rahmenkopfmittel 16 abgekehrten Seite.The chassis cheek 6 is supported by a frame 13 of the Cable 9 is formed and belongs to it in the direction elongated extending parallel to the running rail 2 Frame base means 14 on which the two wheels 12 are rotatably mounted, and two on the frame base means 14 attached frame head means 15 and 16. Die Frame head means 15 and 16 are stable flange plates, which are screwed onto the frame base means 14 and run parallel and at a distance from each other. Between the two frame head means 15 and 16 is a cable drum 17 rotatably supported by a drive motor 18th is driven by a gear 19. Like FIG. 2 can be seen further, the gear 19 on the frame head means 15 screwed, and it is on the side facing away from the frame head means 16.

    Der Vollständigkeit halber sei an dieser Stelle noch erwähnt, daß auf dem Getriebe 19 ein Anschluß- und Steuerkasten 21 angeordnet ist.For the sake of completeness, I would like to take this opportunity mentions that on the gear 19 a connection and control box 21 is arranged.

    Wie Fig. 3 zeigt, umfaßt das Getriebe 19 ein Getriebegehäuse 22, das von zwei zueinander parallelen und im Abstand zueinander angeordneten Gehäusestirnwänden 23 und 24 sowie einer zwischen den beiden Gehäusestirnwänden 23 und 24 sich erstreckenden, allseitig geschlossenen Seitenwandanordnung 25 gebildet ist. Die Seitenwandanordnung 25 ist mit den beiden Gehäusestirnwänden 23 und 24 einstükkig. Hierdurch wird eine besonders verwindungssteife Konstruktion erreicht, die in der Lage ist, unmittelbar den Motor 18 zu haltern.3 shows, the gear 19 comprises a gear housing 22, the two parallel to each other and in Distance from each other housing end walls 23 and 24 and one between the two housing end walls 23 and 24 extending side wall assembly closed on all sides 25 is formed. Sidewall assembly 25 is in one piece with the two housing end walls 23 and 24. This makes it particularly rigid Construction achieved that is able to immediately to hold the motor 18.

    Der Motor 18 ist mit Hilfe nicht weiter gezeigter Befestigungsmittel an der in diesem Bereich entsprechend verstärkten Gehäusestirnwand 24 angeschraubt, wobei seine Ankerwelle 26 durch eine Bohrung 27 in der Gehäusestirnwand 24 in das Innere des Getriebegehäuses 22 hineinragt. Auf dem in das Getriebegehäuse 22 ragenden Ende der Ankerwelle 26 sitzt drehfest ein Antriebsritzel 28. Dieses Antriebsritzel 28 kämmt mit einem Zahnrad 29, das zusammen mit einem weiteren Ritzel 31 auf einer Vorgelegewelle 32 drehfest angeordnet ist.The motor 18 is not shown further with the help Fasteners on the corresponding in this area reinforced housing end wall 24 screwed, its Armature shaft 26 through a bore 27 in the housing end wall 24 protrudes into the interior of the gear housing 22. On the end of the armature shaft projecting into the gear housing 22 26 sits a drive pinion 28 in a rotationally fixed manner Drive pinion 28 meshes with a gear 29 that together with a further pinion 31 on a countershaft 32 is rotatably arranged.

    Die Vorgelegewelle 32 ist mit Hilfe zweier Wälzlager 33 und 34 drehbar gelagert. Das Wälzlager 33 befindet sich in einer Lagersitzbohrung 35 in der Gehäusestirnwand 23, während das Kugellager 34 in einer Lagersitzbohrung 36 angeordnet ist, die sich in einer Ausstülpung der Gehäusestirnwand 24 befindet. Die beiden Lagersitze 35 und 36 fluchten miteinander.The countershaft 32 is by means of two roller bearings 33 and 34 rotatably mounted. The roller bearing 33 is located in a bearing seat bore 35 in the housing end wall 23, while the ball bearing 34 in a bearing seat bore 36 is arranged, which is in a protuberance of the housing end wall 24 is located. The two bearing seats 35 and 36 cursed with each other.

    Das Getriebe 19 enthält achsparallel zu der Vorgelegewelle 32 eine Ausgangswelle 37, die ebenfalls mit Hilfe zweier Kugellager 38 und 39 in dem Getriebegehäuse 22 drehbar gelagert ist. Dort, wo sich das Kugellager 38 befindet, ist in der Gehäusestirnwand 23 eine nach innen ragende Ausstülpung 41 vorhanden, die mit einer Lagersitzbohrung 42 versehen ist, in die das Kugellager 38 eingepreßt ist. Die Lagersitzbohrung 42 endet an einer Ringschulter 43.The transmission 19 contains axially parallel to the countershaft 32 an output shaft 37, also with the help two ball bearings 38 and 39 in the gear housing 22 is rotatably mounted. Where the ball bearing 38 is located in the housing end wall 23 an inward protruding protuberance 41 available with a bearing seat bore 42 is provided into which the ball bearing 38 is pressed. The bearing seat bore 42 ends at one Ring shoulder 43.

    Mit der Lagersitzbohrung 42 fluchtet eine Lagersitzbohrung 44, die sich an einer nach innen weisenden Ausstülpung 45 der Gehäusestirnwand 24 eingearbeitet ist. Die Lagersitzbohrung 44 hat einen größeren Durchmesser als die Lagersitzbohrung 42, so daß, obwohl das Gehäuse einstückig ist, das Kugellager 38 durch die Lagersitzbohrung 44 hindurch in die Lagersitzbohrung 42 eingepreßt werden kann. Ein weiter außen angeordneter Sprengring 46 sichert das Kugellager 39 nach außen zu in der Lagersitzbohrung 44.A bearing seat bore is aligned with the bearing seat bore 42 44, which is on an inward protuberance 45 of the housing end wall 24 is incorporated. The Bearing seat bore 44 has a larger diameter than that Bearing seat bore 42 so that, although the housing is in one piece the ball bearing 38 through the bearing seat bore 44 are pressed into the bearing seat bore 42 can. A snap ring 46 located further out secures the ball bearing 39 to the outside in the bearing seat bore 44.

    Auf der Ausgangswelle 37 sind zwei an die Kugellager 38 und 39 angepaßte Lagersitze 47 und 48 ausgebildet, die voneinander auch den Abstand entsprechend der beiden Kugellager 38 und 39 haben.On the output shaft 37 are two to the ball bearings 38 and 39 adapted bearing seats 47 and 48 formed the from each other also the distance corresponding to the two Ball bearings 38 and 39 have.

    Beide Lagersitze 47 und 48 sind Zylinderflächen, wobei der Durchmesser des Lagersitzes 47 kleiner ist als der Durchmesser des Lagersitzes 48. Zwischen den beiden Lagersitzen 47 und 48 ist bei 49 eine Profilverzahnung ausgebildet, beispielsweise eine Vielkeilverzahnung, die der drehfesten Aufnahme einer Nabenbohrung eines Ausgangszahnrades 51 dient. Das Ausgangszahnrad 51 kämmt mit dem Ritzel 31 und liegt mit der rechten Stirnseite an dem Innenlagerring des Rillenkugellagers 38 an. Damit das Ausgangszahnrad 51 auf der Ausgangswelle 37 nicht nach links verrutschen kann, befindet sich zwischen dem Rillenkugellager 39 und dem Ausgangszahnrad 51 ein Distanzring 52 auf der Ausgangswelle 37.Both bearing seats 47 and 48 are cylindrical surfaces, the diameter of the bearing seat 47 is smaller than the diameter of the bearing seat 48. Between the two Bearing seats 47 and 48 is a profile toothing at 49 formed, for example a spline toothing, the the rotationally fixed receptacle of a hub bore of an output gear 51 serves. The output gear 51 meshes with the Pinion 31 and lies with the right front side on the Inner bearing ring of the deep groove ball bearing 38. So that Output gear 51 on the output shaft 37 does not follow left can slip, is located between the deep groove ball bearing 39 and the output gear 51 a spacer ring 52 on the output shaft 37.

    Eine, bezogen auf Fig. 3 nach rechts gerichtete Axialkraft der Ausgangswelle 37, wird von einer an dem Lagersitz 48 ausgebildeten Ringschulter über den Innenlagerring des Rillenkugellagers 39, die Distanzhülse 52 und das Ausgangszahnrad 51 auf das Rillenkugellager 38 übertragen, das sich an der Ringschulter 43 abstützt. Eine nach links gerichtete Kraft hingegen wird von der Ausgangswelle 37 über einen Sprengring 53 auf die rechte Außenseite des inneren Lagerrings des Rillenkugellagers 38 eingeleitet und von dort über das Ausgangszahnrad 51, die Distanzbüchse 52 und das Rillenkugellager 39 auf den Sprengring 46 übertragen.One directed to the right in relation to FIG. 3 Axial force of the output shaft 37 is from one to the Bearing seat 48 trained ring shoulder over the bottom bracket ring of the deep groove ball bearing 39, the spacer sleeve 52 and the output gear 51 on the deep groove ball bearing 38 transferred, which is supported on the annular shoulder 43. A left-hand force, however, is from the output shaft 37 via a snap ring 53 on the right Outside of the inner bearing ring of the deep groove ball bearing 38 initiated and from there via the output gear 51, the Spacer sleeve 52 and the deep groove ball bearing 39 on the Transfer snap ring 46.

    Die Ausgangswelle 37 geht an ihrer der Gehäusestirnwand 24 benachbarten Seite in einen Halsteil 54 über, der durch eine Öffnung 55 in dem Rahmenkopfmittel 15 hindurchragt.The output shaft 37 goes on the housing end wall 24 adjacent side into a neck portion 54, the protrudes through an opening 55 in the frame head means 15.

    An den Halsteil 54 ist auf der anderen Seite des Rahmenkopfmittels 15 ein zylindrischer Ansatz 56 angeformt, an den sich schließlich eine ringförmige Stirnplatte 57 anschließt.On the neck part 54 is on the other side of the A cylindrical projection 56 is formed on the frame head means 15, to which there is finally an annular faceplate 57 connects.

    Die ringförmige Stirnplatte 57 ist eine zylindrische dicke Scheibe mit einer zylindrischen Außenumfangsfläche 58, die an der von dem Halsteil 54 abliegenden Stirnseite in eine plangedrehte Ringfläche 59 übergeht. In der Stirnplatte 57 befinden sich insgesamt vier Gewindebohrungen 61, die in radialer Richtung nach außen hin in Paßbohrungen 62 übergehen.The annular end plate 57 is a cylindrical one thick disc with a cylindrical outer peripheral surface 58, on the end face remote from the neck part 54 into a face-turned annular surface 59. In the faceplate 57 there are a total of four threaded holes 61, which radially outwards in fitting holes 62 pass over.

    Die Seiltrommel 17 selbst ist ein im wesentlichen zylindrisches Rohr, in dessen Außenumfangsfläche Seilrillen 63 eingearbeitet sind. An ihren beiden Stirnenden 64 und 65 ist die Seiltrommel 17 mit Aufnahmesitze bildenden Ausdrehungen 66 und 67 versehen. Die Ausdrehung 66 besteht aus einer von der Stirnende 64 her ausgehenden zylindrischen Bohrung 68, die zu der Achse der Seiltrommel 17 konzentrisch ist. An ihrem innenliegenden Ende wird die zylindrische Ausdrehung 68 von einer Ringschulter 69 begrenzt. Der Durchmesser der Zylinderfläche 68 ist exakt gleich dem Außendurchmesser der Zylinderfläche 58 auf der Stirnplatte 57.The cable drum 17 itself is essentially one cylindrical tube with rope grooves in its outer circumferential surface 63 are incorporated. On both ends 64 and 65 is the cable drum 17 with receiving seats Provided turns 66 and 67. The recess 66 exists from a cylindrical starting from the front end 64 Bore 68 leading to the axis of the cable drum 17 is concentric. At its inner end the cylindrical recess 68 from an annular shoulder 69 limited. The diameter of the cylinder surface 68 is exact equal to the outer diameter of the cylinder surface 58 on the Face plate 57.

    Schließlich enthält die Seiltrommel im Bereich der Ausdrehung 66 mehrere radial verlaufende Paßbohrungen 71, die hinsichtlich des Durchmessers und der Anzahl mit den Paßbohrungen 62 in der Stirnplatte 57 übereinstimmen.Finally, the rope drum contains in the area of Recess 66 a plurality of radially extending fitting bores 71, the in terms of diameter and number with the Fitting holes 62 in the end plate 57 match.

    Im zusammengesteckten Zustand liegt die Ringfläche 59 auf der Ringschulter 69 auf und es fluchten die Paßbohrungen 71 mit den Paßbohrungen 62. In diesem Zustand kann in die Gewindebohrung 61 eine entsprechende Anzahl von Paßschrauben 72 eingedreht werden, deren Schaft aus einem Gewindeabschnitt 73 und einem Paßteilabschnitt 74 besteht.In the assembled state, the annular surface 59 lies on the ring shoulder 69 and the alignment holes are aligned 71 with the fitting holes 62. In this state in the threaded bore 61 a corresponding number of Fit screws 72 are screwed in, the shaft of one Threaded section 73 and a fitting section 74.

    An dem anderen Stirnende 65 ist die Seiltrommel 17 in der gleichen Weise ausgeführt, weshalb für die dort vorkommenden Strukturelemente insoweit dieselben Bezugszeichen verwendet sind. The cable drum 17 is in at the other end 65 executed in the same way, which is why for those occurring there Structural elements in this respect the same reference numerals are used.

    In der Ausdrehung 67 an dem Stirnende 65 sitzt eine weitere Stirnplatte 75, die hinsichtlich ihrer Umfangskontur mit der Stirnplatte 57 identisch ist. Der Unterschied besteht lediglich darin, daß die Stirnplatte 57 in die Ausgangswelle 37 übergeht, hingegen die Stirnplatte 75 in einen Lagerzapfen 76. Die für das Zusammenwirken mit der Seiltrommel 17 notwendigen Strukturelemente an der Stirnplatte 75 sind deswegen mit denselben Bezugszeichen belegt wie bei der Stirnplatte 57.One sits in the recess 67 at the front end 65 further face plate 75, with respect to its peripheral contour is identical to the end plate 57. The difference consists only in that the end plate 57 in the Output shaft 37 merges, however, the end plate 75 in a journal 76. The for interaction with the Rope drum 17 necessary structural elements on the end plate 75 are therefore given the same reference numerals as with the face plate 57.

    Der Lagerzapfen 76 ist mit einer Sitzfläche 77 für ein Rillenkugellager 78 und eine Anschlagschulter 79 versehen, an der der Innenlagerring des Rillenkugellagers 78 anliegt. Das Rillenkugellager 78 wird auf dem Lagerzapfen 76 mittels eines Sprengrings 81 axial gesichert.The bearing pin 76 is with a seat 77 for a deep groove ball bearing 78 and a stop shoulder 79 provided on the inner bearing ring of the deep groove ball bearing 78 is present. The deep groove ball bearing 78 is on the journal 76 axially secured by means of a snap ring 81.

    Das Rillenkugellager 78 steckt in einer zylindrischen Lagersitzbohrung 82 eines Lagersitzträgers 83, der mit seinem nach außen weisenden Flansch 84 auf der Außenseite des Rahmenkopfmittels 16 festgeschraubt sind. Hierzu führt eine entsprechende Anzahl von Schrauben 85 durch entsprechende Bohrungen in dem Lagerträger 83 und dem plattenoder blechförmigen Rahmenkopfmittel 16.The deep groove ball bearing 78 is in a cylindrical Bearing seat bore 82 of a bearing seat carrier 83, the its outward-facing flange 84 on the outside of the frame head means 16 are screwed tight. This leads a corresponding number of screws 85 by corresponding Bores in the bearing bracket 83 and the plate or sheet-shaped frame head means 16.

    Die axiale Sicherung des Rillenkugellagers 78 in der Lagerbohrung 82 geschieht mit Hilfe von zwei entsprechend voneinander beabstandeten Innensprengringen 86 und 87.The axial securing of the deep groove ball bearing 78 in the Bearing bore 82 happens with the help of two accordingly spaced-apart inner snap rings 86 and 87.

    Die Montage des beschriebenen Seilzugs 9 geschieht in der Weise, daß zunächst das Kugellager 34 in den zugehörigen Lagersitz 36 eingepreßt wird. Sodann wird durch eine nicht erkennbare Öffnung in der Seitenwandanordnung 25 das Zahnrad 39 eingeführt, bis dessen Nabenbohrung mit der Aufnahmebohrung in dem Kugellager 34 fluchtet. Nun kann durch die noch freie Lagersitzbohrung 35 die mit dem Ritzel 31 verzahnte Vorgelegewelle 32 eingesteckt werden, wobei sie durch das Zahnrad 29 hindurchgleitet und von dem Kugellager 34 aufgenommen wird. Anschließend wird das Wälzlager 33 eingepreßt, womit die Vorgelegewelle 32 beidends gelagert ist und außerdem eine drehfeste Verbindung über eine nicht weiter erkennbare Vielzahnverzahnung mit dem Zahnrad 29 hergestellt ist.The cable 9 described is assembled in the way that first the ball bearing 34 in the associated Bearing seat 36 is pressed. Then by a not recognizable opening in the side wall assembly 25 that Gear 39 introduced until the hub bore with the Receiving hole in the ball bearing 34 is aligned. Well now through the still free bearing seat bore 35 with the Pinion 31 toothed countershaft 32 are inserted, sliding through the gear 29 and from the Ball bearing 34 is added. Then that will Rolling bearing 33 is pressed in, with which the countershaft 32nd is mounted on both ends and also a non-rotatable connection via a not recognizable multi-tooth toothing is made with the gear 29.

    Als nächstes erfolgt die Montage der Ausgangswelle 37, indem zunächst das Kugellager 38 in den zugehörigen Lagersitz 42 eingepreßt wird. Auf die Ausgangswelle 37 wird das Kugellager 39 auf den Sitz 48 aufgeschoben, bis es an der den Lagersitz 48 begrenzenden Ringschulter anliegt. Anschließend wird der Distanzring 52 aufgesteckt. Nunmehr wird durch eine in der Seitenwandanordnung 25 enthaltene Montageöffnung das Ausgangszahnrad 51 eingeführt, und es wird die Ausgangswelle 37 von der Lagerbohrung 44 her in das Getriebegehäuse 22 eingesteckt, wobei die Ausgangswelle 37 durch die entsprechend verzahnte Nabenbohrung des Ausgangszahnrads 51 hindurchgleitet, bis der Lagersitz 47 in dem Rillenkugellager 38 steckt. In dieser Endstellung kann der Sprengring 53 auf die Ausgangswelle 37 aufgeschnappt und es kann außerdem der Sprengring 46 zum Sichern des Kugellagers 39 eingesetzt werden. Damit ist das Getriebe 19 im wesentlichen fertig montiert.The next step is to assemble the output shaft 37 by first the ball bearing 38 in the associated Bearing seat 42 is pressed. On the output shaft 37 the ball bearing 39 is pushed onto the seat 48 until it on the ring shoulder delimiting the bearing seat 48 is present. The spacer ring 52 is then slipped on. Now, in the side wall arrangement 25 included assembly opening inserted the output gear 51, and it becomes the output shaft 37 from the bearing bore 44 ago inserted into the gear housing 22, wherein the output shaft 37 through the corresponding toothed Hub bore of the output gear 51 slides through until the bearing seat 47 is in the deep groove ball bearing 38. In this end position, the snap ring 53 on the output shaft 37 snapped and it can also be the Snap ring 46 is used to secure the ball bearing 39 become. The transmission 19 is thus essentially finished assembled.

    An das insoweit fertig montierte Getriebe wird der Motor 18 angeflanscht und mit Hilfe nicht erkennbarer Schrauben an entsprechenden Fortsätzen der Gehäusestirnwand 24 festgeschraubt. Das auf der Ankerwelle 26 drehfest sitzende Ritzel 28 greift in die Verzahnung des Vorgelegewellenzahnrads 29 ein.To that extent the gearbox is fully assembled Motor 18 flanged and not recognizable with the help Screws on corresponding extensions of the housing end wall 24 screwed tight. That on the armature shaft 26 rotatably seated pinion 28 engages in the toothing of the countershaft gear 29 a.

    Die so vormontierte Baueinheit, bestehend aus dem Antriebsmotor 18 und dem Getriebe 19, läßt sich nun ohne weiteres an dem Rahmenkopfmittel 15 mit Hilfe von Befestigungsschrauben 91 anschrauben, wobei die mit der Ausgangswelle 37 einstückige Stirnplatte 57 in den Raum zwischen den beiden Rahmenkopfmitteln 15, 16 ragt.The pre-assembled unit consisting of the Drive motor 18 and the gear 19 can now be without further on the frame head means 15 with the aid of fastening screws Screw on 91, the one with the output shaft 37 one-piece end plate 57 in the space between protrudes the two frame head means 15, 16.

    Als nächstes wird die Seiltrommel 17 mit der Stirnplatte 75 versehen, indem diese bis zum Anschlag an der Schulter 69 in die Ausdrehung 67 eingeschoben und mittels der Paßschrauben 72 festgeschraubt wird. Sodann kann das Rilenkugellager 78 auf den Lagerzapfen 76 aufgesteckt und mittels des Sprengrings 81 gesichert werden. Dieses Rillenkugellager 78 wurde zuvor in dem Lagerträger 83 eingebaut und dort mit Hilfe der beiden Sprengringe 86 und 87 axial festgelegt.Next, the cable drum 17 with the end plate 75 provided by this up to the stop on the Shoulder 69 inserted into the recess 67 and by means of the fitting screws 72 is screwed tight. Then it can Rilenkugellager 78 plugged onto the journal 76 and be secured by means of the snap ring 81. This deep groove ball bearing 78 was previously installed in the bearing bracket 83 and there with the help of the two snap rings 86 and 87 axially fixed.

    Nachdem die Seiltrommel 17 insoweit vormontiert ist, wird ihr anderes Stirnende 64 auf die Flanschplatte 57 aufgesteckt und es wird der Lagerträger 83 mit dem Rahmenkopfmittel 16 verschraubt. Als letztes werden die Paßschrauben 72 in die Stirnplatte 57 eingedreht, womit die Montage beendet ist.After the cable drum 17 has been pre-assembled so far, her other end 64 will be on the flange plate 57 attached and it becomes the bearing bracket 83 with the frame head means 16 screwed. Lastly, the fitting screws 72 screwed into the end plate 57, with which the Assembly is complete.

    Ersichtlicherweise wird bei dem beschriebenen Seilzug 1 die Seiltrommel 17 durch ein eigenes Trommellager im Bereich des Rahmenkopfmittels 16 und anderenends lediglich durch die Lager der Ausgangswelle 37 gelagert. Ein separates Lager zur Lagerung der Seiltrommel 17 auf der Getriebeseite ist nicht vorhanden. Außerdem kann ohne weiteres eine vormontierte Einheit, bestehend aus Getriebe 19 und Motor 18 erzeugt werden, die zur Endmontage leicht mit der Seiltrommel 17 verbindbar ist.Obviously, the cable described 1 the cable drum 17 by its own drum bearing in Area of the frame head means 16 and the other end only supported by the bearings of the output shaft 37. A separate one Bearing for storing the cable drum 17 on the transmission side is not available. It can also easily a pre-assembled unit consisting of gear 19 and Motor 18 are generated, which is easy to final assembly with Cable drum 17 is connectable.

    Bei einem Seilzug ist die Ausgangswelle des Getriebes einstückig mit einer Stirnplatte versehen. Diese Stirnplatte ist so gestaltet, daß sie in einem Aufnahmesitz der rohrförmigen Seiltrommel eingesteckt werden kann. Mit Hilfe von radialen Paßschrauben wird die Stirnplatte in der Seiltrommel verschraubt.In the case of a cable pull, the output shaft is the gearbox provided in one piece with a front plate. This faceplate is designed in such a way that it is in a seating position tubular rope drum can be inserted. With With the help of radial fitting screws, the face plate is in screwed the cable drum.

    An dem anderen Ende der Seiltrommel ist ebenfalls eine Ausdrehung vorhanden, in der eine ähnliche Stirnplatte in gleicher Weise befestigt ist. Diese andere Stirnplatte trägt einen Lagerzapfen. Aufgrund dieser Anordnung wird die Herstellung der Seiltrommel und der gesamte Zusammenbau vereinfacht, wobei aufwendige Wellengelenke zwischen der Ausgangswelle und der Seiltrommel wegen der Lagerung der Seiltrommel mittels der Ausgangswelle des Getriebes entfallen. Außerdem kann der Seilzug zum Versand in vergleichsweise kleine Baugruppen zerlegt werden.At the other end of the rope drum is also a recess in which a similar end plate is attached in the same way. This other End plate carries a bearing journal. Based on these The arrangement is the manufacture of the rope drum and the entire assembly simplified, with elaborate shaft joints between the output shaft and the cable drum because of the storage of the rope drum by means of the output shaft of the transmission are eliminated. The cable can also disassembled into comparatively small assemblies for shipping become.
