Abstract
Description
Die gegenständliche Erfindung betrifft eine Laufrolle für das Fahrwerk des Fahrbetriebsmittels einer Seilbahnanlage mit einem scheibenartigen, aus Metall, insbesondere aus Stahl, hergestellten Rollkörper, welcher längs seines Umfanges mit einer diesen umgebenden, aus einem Kunststoffmaterial hergestellten Lauffläche ausgebildet ist.The subject invention relates to a roller for the chassis of Operating means of a cable car system with a disc-like, made of metal, especially made of steel, rolling body, which along its Circumference with a surrounding, made of a plastic material Tread is formed.
Es ist bei Seilbahnanlagen bekannt, die Fahrbetriebsmittel einerseits mit Klemmen auszubilden, mittels welcher sie an das Förderseil anklemmbar sind und diese andererseits mit Fahrwerken auszubilden, mittels welcher sie in den Stationen nach Öffnung der Klemmen längs Führungsschienen verfahrbar sind. Bei diesen bekannten Seilbahnanlagen wird das Förderseil mit einer Geschwindigkeit von etwa 8m/sec im Umlauf gehalten. In den Stationen werden die Fahrbetriebsmittel vom Förderseil abgekuppelt und durch den Stationsbereich längs Führungsschienen mit einer solchen Geschwindigkeit hindurch bewegt, daß sie von den Passagieren verlassen bzw. bestiegen werden können.It is known in cable car systems that the operating resources are used on the one hand Form clamps, by means of which they can be clamped to the conveyor cable are and to train them on the other hand with trolleys, by means of which they Can be moved along guide rails in the stations after opening the clamps are. In these known cable car systems, the haul rope is included circulated at a speed of about 8m / sec. In the stations the driving equipment is uncoupled from the conveyor cable and through the Station area along guide rails at such a speed moved through that the passengers leave or climb them can.
Es ist dabei bekannt, die Laufrollen aus einem metallischen Werkstoff herzustellen. Derartige bekannte Laufrollen sind jedoch deshalb nachteilig, da durch ihre Bewegung längs der gleichfalls aus Metall hergestellten Führungsschienen eine sehr starke Geräuschentwicklung verursacht wird. Um die Fahrgeräusche möglichst gering zu halten, ist es weiters bekannt, die Rollen des Laufwerkes aus einem Kunststoffmaterial herzustellen. Derartigen Laufrollen haftet jedoch der Nachteil an, daß sie wesentlich stärker bruchgefährdet sind, als dies für aus Metall hergestellte Laufrollen zutrifft. Soferne der Bruch einer Laufrolle eintritt, können hierdurch sehr schwerwiegende Betriebsstörungen bedingt werden. Insbesondere besteht im Bereich der Ankupplung des Fahrbetriebsmittels an das Förderseil die Gefahr, daß das Förderseil durch die Klemmen nicht erfaßt wird, wodurch es bei der Ausfahrt des Fahrbetriebsmittels aus der Station zu dessen Absturz kommen kann. Um diese Gefahr auszuschließen, ist es bekannt, zusätzliche Führungsschienen anzuordnen, durch welche gewährleistet werden soll, daß auch bei einem Bruch einer Laufrolle das Förderseil durch die Klemmen erfaßt wird. Diese zusätzlichen Führungsschienen entsprechen jedoch deshalb nicht den bestehenden Erfordernissen, da sie einen weiteren hohen konstruktiven Aufwand bedingen und da auch durch diese keine Sicherheit für die ordnungsgemäße Funktion der Klemmen erzielt wird.It is known to produce the rollers from a metallic material. However, such known rollers are disadvantageous because by their movement along the guide rails, which are also made of metal a very strong noise is caused. To the It is also known to keep driving noises as low as possible to manufacture the drive from a plastic material. Such rollers however, there is the disadvantage that it is much more likely to break than is the case for castors made of metal. Soferne the If a roller breaks, this can result in very serious malfunctions be conditioned. In particular, there is in the area of the coupling of the driving equipment to the conveyor cable, the risk that the conveyor cable is not detected by the terminals, which makes it when the Driving equipment from the station can crash. Around To rule out this danger, it is known to use additional guide rails to arrange, by which it is to be ensured that even with one If a roller breaks, the conveyor cable is caught by the clamps. This however, additional guide rails do not correspond to the existing ones Requirements, as they require a further high level of design effort condition and because of this no security for the proper Function of the terminals is achieved.
Aus der US-A-4095846 ist eine Laufrolle für kleine verfahrbare Geräte, wie Einkaufswagen, bekannt, welche einen aus Metall bestehenden Rollenkörper, der mit einer aus Kunststoff bestehenden Lauffläche ausgebildet sind, aufweisen. Da die Belastungen von Laufrollen von kleinen verfahrbaren Geräten wesentlich geringer sind, als die Belastungen von Laufrollen für Fahrwerke der Fahrbetriebsmittel von Seilbahnanlagen, stellt jedoch diese Literaturstelle keinen relevanten Stand der Technik dar.From US-A-4095846 is a roller for small movable devices, such as Shopping cart, known, which has a roll body made of metal, which are formed with a tread made of plastic. Because the loads on rollers of small mobile devices are significant are lower than the loads on rollers for the chassis Driving resources of cable car systems, however, provides this reference does not represent a relevant state of the art.
Ein Laufrad dieser Art ist ebenfalls aus der US-A-3 843 202 bekannt.An impeller of this type is also known from US-A-3 843 202.
Der gegenständlichen Erfindung liegt die Aufgabe zugrunde, eine Laufrolle zu schaffen, durch welche die den bekannten Laufrollen in Fahrwerken von Fahrbetriebsmitteln in Seilbahnanlagen anhaftenden Nachteile vermieden werden. Dies wird erfindungsgemäß dadurch erzielt, daß der Rollenkörper an seinem Umfang mit zwei voneinander im Abstand befindlichen ringartigen Vorsprüngen ausgebildet ist, deren Außendurchmesser mindestens 80% des Außendurchmessers der Laufrolle beträgt, deren außen liegende Seitenflächen sich voneinander in einem Abstand von mindestens 65% des Abstandes der seitlichen Führungsflächen der Laufrolle befinden und welche längs des Umfanges des Rollenkörpers mit Durchbrechungen, insbesondere Bohrungen, ausgebildet sind, welche vom Kunststoffmaterial der Lauffläche durchsetzt sind.The objective of the present invention is to provide a roller create, through which the well-known rollers in undercarriages of Avoid disadvantages inherent in driving equipment in cable car systems become. This is achieved according to the invention in that the roller body its circumference with two ring-like spaced apart Is formed projections whose outer diameter is at least 80% of Outside diameter of the roller is the outer side surfaces each other at a distance of at least 65% of the distance the side guide surfaces of the roller and which along the Circumference of the roller body with openings, in particular bores, are formed, which is penetrated by the plastic material of the tread are.
Dadurch, daß der Rollenkörper aus einem Metall hergestellt ist, ist die Bruchgefahr der Laufrolle auf ein zulässiges Ausmaß herabgesetzt. Dadurch weiters, daß der Rollenkörper mit einer aus Kunststoffmaterial hergestellten Lauffläche versehen ist, werden die Laufgeräusche der Laufrolle auf das angestrebte Ausmaß herabgesetzt. Da weiters nur die Lauffläche aus einem Kunststoffmaterial hergestellt ist und zudem die Dimension der ringartigen Vorsprünge nur geringfügig kleiner sind als die Dimensionen der Laufrolle selbst, übernimmt im Falle eines Bruches der Lauffläche der aus Metall hergestellte Rollenkörper die Funktion der Laufrolle, wodurch die während des Kupplungsvorganges der Klemmen erforderlichen Notlaufeigenschaften erzielt werden. Durch eine derartige Laufrolle werden somit die dem bekannten Stand der Technik anhaftenden Nachteile vollständig vermieden.Because the roller body is made of a metal, there is a risk of breakage the roller reduced to a permissible extent. Furthermore, that the roller body with a made of plastic material Tread is provided, the running noise of the roller on the desired Diminished extent. Since only the tread from one Plastic material is made and also the dimension of the ring-like Projections are only slightly smaller than the dimensions of the roller itself, takes over in case of a tread breakage, the one made of metal Roller body the function of the roller, which the during the Coupling process of the terminals required emergency running properties achieved become. With such a roller, the known Disadvantages inherent in the prior art are completely avoided.
Vorzugsweise beträgt der Außendurchmesser der ringartigen Vorsprünge 90% bis 95% des Außendurchmessers der Laufrolle und befinden sich die außenliegenden Seitenflächen der ringartigen Vorsprünge voneinander in einem Abstand von 75% der seitlichen Führungsflächen der Laufrolle.The outer diameter of the ring-like projections is preferably 90% to 95% of the outer diameter of the roller and are the outer side surfaces of the ring-like projections from each other in one Distance of 75% of the side guide surfaces of the roller.
Maßgeblich für die Funktion der Notlaufeigenschaften des Rollenkörpers ist es, daß dieser sowohl in seinem Durchmesser als auch in seiner Breite der Laufrolle weitgehend entspricht, um hierdurch die erforderliche Höhenlage und Seitenlage der Klemme für den Kupplungsvorgang zu gewährleisten.The decisive factor for the function of the emergency running properties of the roller body is it that this both in its diameter and in its width of the Roller largely corresponds to the required altitude and to ensure that the clamp is on its side for the coupling process.

Since these are structural designs which are known from the prior art, they are not further explained.
Wie dies aus Fig.3 ersichtlich ist, ist das Laufwerk 4 mit mindestens zwei
Lagerbolzen 41 ausgebildet, auf welchen mittels eines Kugellagers 42 eine
Laufrolle 5 gelagert ist. Zur Befestigung des Kugellagers 42 ist die Stirnfläche
des Lagerbolzens 41 als Sicherungsdeckel 43 ausgebildet, durch welchen ein
. Sicherungsring 44 gehalten ist, welcher das Kugellager 42 axial übergreift,
wodurch es in axialer Richtung lagegesichert ist. Zudem ist die Führungsschiene
11 dargestellt, in welcher die Laufrollen 5 geführt sind.As can be seen from Figure 3, the
Die Laufrollen 5 bestehen aus einem Rollenkörper 51, welcher aus einem
Metall, insbesondere aus Stahl, hergestellt ist, und aus einem Laufring 61,
welcher aus einem Kunststoffmaterial, insbesondere aus Polyamid, hergestellt
ist. Durch den Laufring 61 wird die angestrebte geräuscharme Bewegung der

Im oberen Teil der Zeichnung ist eine vollständige Laufrolle 5, welche an
ihrem Außenumfang mit dem Laufring 61 ausgebildet ist, dargestellt. Demgegenüber
ist im unteren Teil der Zeichnung die Laufrolle 5, bei welcher der
Laufring 61 weggebrochen ist, dargestellt. In diesem Fall besteht das Erfordernis,
daß durch die Laufrolle 5 solche Notlaufeigenschaften gewährleistet
sind, daß ungeachtet der Beschädigung ein ordnungsgemäßer Kupplungsvorgang
gewährleistet ist. Dies wird dann erzielt, wenn die Laufrolle 5 auch
dann, wenn der Laufring 61 weggebrochen ist, in ihrer Höhenlage und ihrer
Seitenlage gegenüber der Führungsschiene 11 nahezu die gleiche Höhenlage
und die gleiche Seitenlage wie eine unbeschädigte Laufrolle einnimmt. Diese
Forderung wird durch die besondere Ausbildung der Laufrolle 5 entsprochen,

der Laufrolle 5 mit dem Laufring 61 beträgt und bei welchen der Abstand der
äußeren Seitenflanken etwa 75% des Abstandes der Seitenflanken der Laufrolle
5 mit dem Laufring 61 beträgt. Durch diese konstruktive Gestaltung
wird gewährleistet, daß die Laufrolle 5 auch bei einem Bruch des Laufringes
61 nahezu die gleiche Funktion wie die unbeschädigte Laufrolle 5 erfüllt, daß
also Notlaufeigenschaften gewährleistet sind. Dies gilt einerseits hinsichtlich
des Außenumfanges der ringartigen Vorsprünge 52, durch welche die Laufrolle
5 in der Führungsschiene 11 in der nahezu richtigen Höhenlage geführt
ist, als auch hinsichtlich der äußeren Seitenflanken der ringartigen Vorsprünge
52, durch welche die Laufrolle 5 hinsichtlich ihrer Seitenlage in der
Führungsschiene 11 so geführt ist, daß sie auch nahezu die richtige Seitenlage
einnimmt.As shown in Figures 4 and 4a, the
