Abstract

The roller (10) comprises two wheels (11), which are rotatably supported on a common axis by shoulder ball bearings (17). Each wheel has a shoulder ball bearing, such that the two shoulder ball bearings are counter-rotating. An axial slide bearing (21) is provided, which is formed between the wheels. The slide bearing is formed by ring-shaped surfaces (20) of the rims (15).

Description

Die Erfindung betrifft eine Rolle, vorzugsweise Lenkrolle, für Apparate, Geräte, Möbel od. dgl., mit jeweils zwei Rädern, welche mittels Schulterkugellager an einer gemeinsamen Achse drehbar gelagert sind.The Invention relates to a roller, preferably a steering roller, for apparatus, Equipment, Furniture od. Like., With two wheels, which rotatable by means of shoulder ball bearings on a common axis are stored.

Aus dem druckschriftlich nicht belegbaren Stand der Technik sind Doppelrollen bekannt, die je Rad mit zwei gegenläufig angeordneten Schulterkugellagern versehen sind, wobei diese beiden Schulterkugellager im Zusammenwirken jeweils die Axialkräfte in beiden Richtungen übertragen können.Out The documentary uncontrollable prior art are double roles known, the per wheel with two opposing shoulder ball bearings are provided, these two shoulder ball bearings in cooperation each the axial forces transmitted in both directions can.

Diese an sich vorteilhafte Radkonstruktion hat den Nachteil, dass sie eine relativ große Anzahl von Teilen aufweist.These per se advantageous wheel design has the disadvantage that they a relatively large one Number of parts has.

Die Aufgabe der Erfindung besteht deshalb darin, eine Radkonstruktion für eine neue Rolle mit jeweils zwei Rädern zu schaffen, bei der aufgrund der Reduzierung der Teileanzahl das Gewicht und die Kosten reduziert werden können.The The object of the invention is therefore a wheel construction for one new role with two wheels each to create, due to the reduction in the number of parts that Weight and costs can be reduced.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruches 1, insbesondere den Merkmalen des Kennzeichenteils, wonach jedes Rad lediglich ein Schulterkugellager aufweist, dass die beiden Schulterkugellager gegenläufig angeordnet sind und dass zwischen den Rädern ein axiales Gleitlager ausgebildet ist.The solution This object is apparent from the features of claim 1, in particular the Characteristics of the license plate part, according to which each wheel is only a shoulder ball bearing that the two shoulder ball bearings arranged in opposite directions are and that between the wheels an axial sliding bearing is formed.

Die erfindungsgemäße Vorrichtung hat den wesentlichen Vorteil, dass je Rad nur noch ein Schulterkugellager notwendig ist, wodurch sich nicht nur die Teileanzahl verringert, sondern auch das Gewicht und die Kosten reduziert werden. Insbesondere die Gewichtsreduzierung spielt eine große Rolle beim Einsatz derartiger Rollen für Servicefahrzeuge in Flugzeugen.The inventive device has the significant advantage that only one ball bearing per wheel is necessary, which not only reduces the number of parts, but also the weight and the costs are reduced. Especially the weight reduction plays a major role in the use of such Roles for Service vehicles in aircraft.

Des Weiteren ist auch durch Reduzierung des Freiraumes zwischen den einzelnen Rädern auf ein Minimum, die Neigung zur Schmutzaufnahme deutlich verringert.Of Another is also by reducing the space between the individual wheels to a minimum, the tendency to dirt pickup significantly reduced.

Letztlich können bei der erfindungsgemäßen Ausgestaltung der Rolle die Axialkräfte durch zwischen den Feigen angeordnete Axialgleitlager abgefangen werden, wodurch der Spalt zwischen den Rädern nahezu geschlossen werden kann. Das Axialgleitlager kommt dabei lediglich dann zum Einsatz, wenn beim Fahren ein Richtungswechsel vollzogen wird, da erst in dieser Situation sich die beiden Räder relativ zueinander drehen.Ultimately can in the embodiment according to the invention the role of the axial forces intercepted by arranged between the Figs Axialgleitlager be, whereby the gap between the wheels are almost closed can. The thrust bearing is only used when when driving a change of direction is performed, because only in this Situation the two wheels relatively to each other.

Bei einer vorteilhaften Ausgestaltung der Erfindung wird das axiale Gleitlager durch zueinander weisende, ringförmige Flächen der Felgen gebildet.at an advantageous embodiment of the invention, the axial Slide bearing formed by facing each other, annular surfaces of the rims.

Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles. Es zeigen:Further Advantages of the invention will become apparent from the following description an embodiment. Show it:

1 eine Schnittdarstellung durch eine Doppelrolle nach dem Stand der Technik und 1 a sectional view through a double role according to the prior art and

2 eine Schnittdarstellung durch eine erfindungsgemäße Doppelrolle. 2 a sectional view through a double role according to the invention.

In der 1 ist eine Doppelrolle A mit einem Traggehäuse B, Laufbelägen C, einer Felge D sowie Konen E dargestellt.In the 1 is a double role A with a support housing B, running surfaces C, a rim D and cones E shown.

Zwei Räder F sind auf einer im Traggehäuse gelagerten Achsschraube G gelagert. Jedes der Räder F weist zwei Schulterkugellager H auf, in denen Kugeln I drehbar gelagert sind.Two Wheels F are mounted on a in the support housing Axle screw G stored. Each of the wheels F has two shoulder ball bearings H, in which balls I are rotatably mounted.

Die erfindungsgemäße Rolle ist in der 2 insgesamt mit der Bezugsziffer 10 bezeichnet. Die Rolle 10 weist zwei Räder 11 auf, welche teilweise vom Traggehäuse 12 umgeben sind und mittels einer im Traggehäuse 12 angeordneten Achsschraube 13 gelagert sind. Jedes Rad 11 wird aus einer auf der Achsschraube angeordneten Kone 14 der Felge 15 und dem Laufbelag 16 gebildet.The role of the invention is in the 2 total with the reference number 10 designated. The role 10 has two wheels 11 on which partially from the support housing 12 are surrounded and by means of a in the support housing 12 arranged axle bolt 13 are stored. Every bike 11 is made of a arranged on the axle screw Kone 14 the rim 15 and the tread 16 educated.

Darüber hinaus weist jedes Rad 11 ein Schulterkugellager 17 mit einer Vielzahl von Kugeln 18 auf, welches zwischen der Felge 15 und der Kone 14 einen Lagerbereich 19 für die Kugeln 18 ausbildet.In addition, every bike points 11 a shoulder ball bearing 17 with a variety of balls 18 on which between the rim 15 and the guy 14 a storage area 19 for the balls 18 formed.

Zwischen den Rädern 11 ist im Bereich von zueinander weisenden ringförmigen Flächen 20 der Felgen 15 ein axiales Gleitlager 21 vorhanden, wodurch zugleich der Innenraum der Rolle 10 weitgehend gegen Schmutzaufnahme geschützt ist.Between the wheels 11 is in the range of facing annular surfaces 20 the rims 15 an axial plain bearing 21 present, whereby at the same time the interior of the role 10 is largely protected against dirt.
