- the end face 19 of the drive motor 2 is formed by a relatively thin cuff 25 made of plastic, from which the motor shaft 11 passes in the middle.
- This cuff 25 has a purely insulating and no supporting function. Also, the cuff 25 has less building mass than the usual motor cover, which also carries the other pivot bearing. However, this second pivot bearing 13 is already mounted in the housing 1 of the chain hoist and is seen from the drive motor 2 from behind the installation space 24th
- FIG. 2 shows in a three-dimensional schematic representation the elements of the chain hoist according to FIG. 1. It can be seen that the transmission input shaft 14 and the transmission output shaft 4 together with the parallel central transmission shaft 23 form a V-shape, wherein the transmission output shaft 4 is slightly above the motor shaft 11 is arranged. As a result, a small width is achieved.

Description
Die Erfindung betrifft einen Kettenzug gemäß dem Oberbegriff des Anspruchs 1. Ein solcher Kettenzug ist aus US-A-2 570 833 bekannt.The invention relates to a chain hoist according to the preamble of
Aufhängbare Kettenzüge sind allgemein bekannt. Diese weisen einen Antriebsmotor und ein nachgeschaltetes Getriebe auf, welche antriebstechnisch miteinander verbunden sind. Das Getriebe kann ein- oder mehrstufig ausgebildet sein, wobei zumindest zwei parallel zueinander verlaufende und voneinander beabstandete Getriebewellen in Form einer Getriebeeingangswelle und einer Getriebeausgangswelle vorhanden sind. Hierbei ist ein Eingangszahnrad des Getriebes auf der Getriebeeingangswelle und ein Ausgangszahnrad auf der Getriebeausgangswelle angeordnet. Bei einem zweistufigen Getriebe kämmt das Eingangszahnrad mit dem Abtriebszahnrad der ersten Stufe, das wiederum das Antriebszahnrad der zweiten Stufe antreibt, welches mit dem Ausgangszahnrad, also dem Abtriebszahnrad der zweiten Stufe, kämmt. Weiter sitzt das Kettenrad drehfest auf der Getriebeausgangswelle.Suspended chain hoists are well known. These have a drive motor and a downstream transmission, which are connected to each other in terms of drive technology. The transmission may be formed in one or more stages, wherein at least two mutually parallel and spaced transmission shafts in the form of a transmission input shaft and a transmission output shaft are present. Here, an input gear of the transmission is arranged on the transmission input shaft and an output gear on the transmission output shaft. In a two-stage transmission, the input gear meshes with the first-stage output gear, which in turn drives the second-stage drive gear, which meshes with the output gear, that is, the second-stage output gear. Next sits the sprocket rotatably on the transmission output shaft.
Der Nachteil dieser bekannten Kettenzüge besteht darin, dass diese nur bedingt eine kompakte Bauweise aufweisen und meist nicht waagerecht ausgerichtet sind, wenn sie an einem Tragelement aufgehängt sind.The disadvantage of these known chain hoists is that they only partially have a compact design and are usually not aligned horizontally when they are suspended from a support element.
Der Erfindung liegt die Aufgabe zugrunde, einen kompakten Kettenzug zu schaffen vorzugsweise sollte dieser Kettenzug ohne äußere Zusatzmaßnahmen an einem Tragelement waagerecht ausgerichtet aufhängbar sein.The invention has for its object to provide a compact chain hoist should preferably this chain hoist without external additional measures on a support element can be suspended horizontally.
Die Aufgabe wird durch einen Kettenzug mit den Merkmalen des Anspruchs 1 gelöst. Die Unteransprüche 2 bis 8 enthalten vorteilhafte Ausgestaltungen des Kettenzugs.The object is achieved by a chain hoist with the features of
Erfindugsgemäß ist zwischen dem Kettenrad und der Stirnseite des Antriebsmotors ein Einbauraum vorhanden dessen als Breite bezeichneter Abstand zwischen dem Kettenrad und der Stirnseite größer als die Breite des Kettenrads ist, so dass das Kettenrad ohne Demontage der Antriebsmotors ausgewechselt werden kann.According to the invention, there is an installation space between the sprocket and the end face of the drive motor whose width, referred to as width, between the sprocket and the end face is greater than the width of the sprocket, so that the sprocket can be replaced without disassembling the drive motor.
Eine Optimierung der Baulänge des Kettenzuges wird trotz vorhandenem Einbauraum dadurch erreicht, dass die Stirnseite des Antriebsmotors ausschließlich über eine Stulpe aus isolierendem Kunststoff gegenüber dem Einbauraum verschlossen ist.An optimization of the overall length of the chain hoist is achieved in spite of existing installation space in that the front side of the drive motor exclusively is closed by a cuff made of insulating plastic opposite the installation space.
Zum Auswechseln wird das Kettenrad einfach nach Lösen eines Federrings zur Stirnseite hin von der Getriebeausgangswelle in den Einbauraum abgezogen und von dort nach unten oder zur Seite entfernt. Hierdurch wird die Wartung des Kettenzuges vereinfacht.To replace the sprocket is simply removed after loosening a spring ring to the front side of the transmission output shaft in the installation space and removed from there down or to the side. This simplifies the maintenance of the chain hoist.
Die Aufhängung des Kettenzuges, der ein auf Grund der einen ablaufenden Kette auch als sogenannter Punktzug bezeichnet wird, kann weiter vereinfacht und somit ohne Zusatzhilfsmittel auskommen, wenn der Ablaufpunkt der Kette von dem Kettenrad im Schwerpunkt des Kettenzugs liegt. Hierdurch wird auch in vorteilhafter Weise kein zusätzliches Gegengewicht benötigt. Zum Aufhängen weist der Kettenzug in bekannter Weise an seiner Oberseite eine Öse auf.The suspension of the chain hoist, which is referred to as a so-called point train on the basis of a running chain, can be further simplified and thus manage without additional aids when the expiry point of the chain of the sprocket is in the center of gravity of the chain hoist. As a result, no additional counterweight is needed in an advantageous manner. To hang the chain hoist in a known manner on its upper side an eyelet.
In konstruktiv vorteilhafter und sehr kompakt bauender Weise ist vorgesehen, dass das Getriebe zumindest ein auf einer Getriebeeingangswelle sitzendes erstes Zahnrad und zumindest ein auf der Getriebeausgangswelle sitzendes weiteres Zahnrad aufweist, wobei die Getriebeeingangswelle und die Getriebeausgangswelle voneinander beabstandet angeordnet sind und parallel zueinander verlaufen sowie die Motorwelle koaxial zur Getriebeeingangswelle angeordnet ist. Hierbei ist weiterhin vorgesehen, dass das Getriebe zweistufig ausgebildet ist und neben der Getriebeeingangswelle und der Getriebeausgangswelle einer weitere Getriebewelle aufweist, die Getriebeeingangswelle, die Getriebeausgangswelle und die Getriebewelle parallel nebeneinander und v-förmig zueinander angeordnet sind, wobei die Getriebeausgangswelle etwas oberhalb der Getriebeeingangswelle und somit der Motorwelle angeordnet ist. Hierdurch wird eine geringe Baubreite erreicht.In a structurally advantageous and very compact design manner is provided that the transmission has at least one seated on a transmission input shaft first gear and at least one seated on the transmission output shaft further gear, wherein the transmission input shaft and the transmission output shaft are spaced from each other and parallel to each other and the motor shaft Is arranged coaxially with the transmission input shaft. In this case, it is further provided that the transmission is formed in two stages and in addition to the transmission input shaft and the transmission output shaft has a further transmission shaft, the transmission input shaft, the transmission output shaft and the transmission shaft parallel to each other and V-shaped to each other, wherein the transmission output shaft is slightly above the transmission input shaft and thus the motor shaft is arranged. As a result, a small width is achieved.

- FIG. 2
- a spatial schematic representation of the chain hoist according to Figure 1.
Die Figur 1 zeigt einen Längsschnitt eines Kettenzugs, der in einem Gehäuse 1 angeordnet ist. Der Kettenzug umfasst als Antriebsanordnung einen elektrischen Antriebsmotor 2 und ein nachgeschaltetes Getriebe 3 mit zwei Getriebestufen. Auf deren Getriebeausgangswelle 4 sitzt drehfest mit dieser verbunden ein Kettenrad 5 für die Kette. Der Kettenzug kann mittels einer nicht dargestellten Öse an einem nicht dargestellten Tragelement aufgehängt werden.1 shows a longitudinal section of a chain hoist in a housing. 1 is arranged. The chain hoist comprises as drive arrangement an
Eine Bremse 6 mit einer Ankerplatte 7 am abtriebsseitigen Ende des Antriebsmotors 2 dient zum Bremsen des Kettenzugs; zur Belüftung ist am gegenüberliegenden Ende ein Lüfter 8 vorgesehen.A
Der Motor 2 weist einen Ständer 9, einen Rotor 9a, eine Motorwicklung 10 und eine Motorwelle 11 auf, die über erstes Drehlager 12 und ein zweites Drehlager 13 abgestützt ist, wobei das antriebsseitige Drehlager 13 gleichzeitig die Motorwelle 11 und die Getriebeeingangswelle 14 abstützt.The
Als Überlastschutz ist zwischen Motorwelle 11 und Getriebeeingangswelle 14 eine Rutschkupplung 15 geschaltet, deren Kupplungsscheiben 16 in Figur 1 dargestellt sind. Die Rutschkupplung 15 wird dabei mit einer Gegenkraft beaufschlagt, die durch sich am Gehäuse 1 abstützende Federscheiben 17 bereit gestellt wird.As overload protection between the
Das zweistufig ausgebildete Getriebe 3 weist eingangsseitig die Getriebeeingangswelle 14 auf, die zur Bildung eines ersten Zahnrades 18a schräg verzahnt ist. Das erste Zahnrad 18a kämmt mit einem zweiten Zahnrad 18b mit einer korrespondierenden Schrägverzahnung, das auf einer mittleren Getriebewelle 23 gelagert ist. Auf dieser mittleren Getriebewelle 23 ist auch das dritte Zahnrad 18c der zweiten Getriebestufe angeordnet, das mit einem auf der Getriebeausgangswelle 4 drehfest sitzenden vierten Zahnrad 18d kämmt und so die Getriebeausgangswelle 4 antreibt. Alle drei Getriebewellen 4, 14 und 23 verlaufen hierbei parallel zueinander sowie mit Abstand voneinander.The two-
Wie die Figur 1 zeigt, ist das Kettenrad 5 sowie eines der beiden Enden der Getriebeausgangswelle 4 der Stirnseite 19 der Abtriebsseite des Antriebsmotors 2 zugewandt. Hierbei ist der Abstand des äußeren und der Stirnseite 19 zugewandten Randes des Kettenrads 5 von dieser Stirnseite 19 so gewählt ist, dass ein Einbauraum 24 gebildet wird, dessen Breite - im Sinne des Abstandes von dem Rand des Kettenrads 5 von der Stirnseite 19 - größer ist als die Breite des zu montierenden oder demontierenden Kettenrades 5. Somit kann das Kettenrad 5 einfach durch Lösen eines am Ende der Getriebeausgangswelle 4 angeordneten Federrings 20 oder eines axialen Wellensicherungsrings das Kettenrad 5 zur Stirnseite 19 hin von der Getriebeausgangswelle 4 abgezogen werden und befindet sich dann in dem Einbauraum 24. Aus diesem Einbauraum 24 kann dann das Kettenrad 5 seitlich vorzugsweise nach unten aus dem Gehäuse 1 des Kettenzuges entfernt werden. Somit ist es möglich, das Kettenrad 5 ohne Demontage der Antriebsanordnung auszuwechseln. Vor dem Lösen des Kettenrads 5 muss lediglich ein seitliches Abdeckteil 20a des Kettenzuges abgenommen werden, um Zugang zu dem Einbauraum 24 zu erhalten.As Figure 1 shows, the
Ein ausreichender Abstand zwischen dem Kettenrad 5 und der Stirnwand ist auch deshalb erforderlich, da - wie Figur 1 zeigt - das Kettenrad 5 sich in die gedachte Verlängerung der Außenkontur des Antriebsmotors 2 hineinerstreckt, die hierbei im wesentlichen von den Motorwicklungen 10 des Ständers 9 bestimmt wird. Die Motorwicklungen 10 sind noch in üblicher Weise von einem Motorgehäuse umgeben. Das Kettenrad 5 ist dabei soweit zur Motorwelle 11 hin verlagert, dass der Ablaufpunkt 21 der Kette jeweils im Schwerpunkt des Kettenzugs liegt. Um trotz vorhanden Einbauraum 24 die kompakte Bauweise des Kettenzuges nicht zu verlassen, ist die Stirnseite 19 des Antriebsmotor 2 durch eine relativ dünne Stulpe 25 aus Kunststoff gebildet, aus der in der Mitte die Motorwelle 11 hindurch tritt. Diese Stulpe 25 hat eine rein isolierende und keine tragende Funktion. Auch weist die Stulpe 25 geringere Baumasse auf als der sonst übliche Motordeckel, der auch das weitere Drehlager trägt. Dieses zweite Drehlager 13 wird jedoch schon im Gehäuse 1 des Kettenzuges gelagert und befindet sich vom Antriebsmotor 2 aus gesehen hinter dem Einbauraum 24.A sufficient distance between the
Die Figur 2 zeigt in einer räumlichen schematischen Darstellung die Elemente des Kettenzugs gemäß Figur 1. Dabei ist erkennbar, dass die Getriebeeingangswelle 14 und die Getriebeausgangswelle 4 zusammen mit der parallelen mittleren Getriebewelle 23 eine V-Form bilden, wobei die Getriebeausgangswelle 4 etwas oberhalb der Motorwelle 11 angeordnet ist. Hierdurch wird eine geringe Baubreite erreicht.FIG. 2 shows in a three-dimensional schematic representation the elements of the chain hoist according to FIG. 1. It can be seen that the
