Description

  

      Laufrolle   <B>aus Kunststoff</B>    Es ist bekannt, Laufrollen aus Kunststoff, bei  spielsweise aus Polyamid, herzustellen und in der  Nabe der Rolle ein Wälzlager, vorzugsweise ein Ku  gellager. zu befestigen. Die Befestigung der Wälz  lager in der Nabe     erfordert    aber zusätzliche     Mittel.     Meist sind die Laufrollen zweiteilig ausgebildet, um  das Wälzlager zwischen beiden Teilen einschliessen  zu können.     Derartige    Laufrollen sind in der Herstel  lung verhältnismässig teuer.  



  Erfindungsgemäss ist die mit einem     Wälzlager     ausgerüstete Laufrolle aus Kunststoff so ausgebildet,  dass die Rollennabe eine     Ausnehmung    zur Auf  nahme des äusseren Lagerringes des Wälzlagers auf  weist, dass der Aussendurchmesser dieses Lagerrin  ges grösser ist als der lichte Durchmesser der Nabe  und der Lagerring selbst aus kreisförmig gebogenen  Drähten oder Bändern besteht, die nach Art von  Sprengringen in die     Ausnehmung    der Rollennabe  eingesetzt sind.  



  Bei dieser Ausbildung der Nabe sind     zusätzliche     Befestigungsmittel nicht erforderlich und die Nabe  selbst kann     einteilig    ausgebildet sein. Sie hat aber  gegenüber den nur aus Kunststoff bestehenden Lauf  rollen den     Vorteil,    dass die     Laufbahn    der Rollen  des Wälzlagers aus sehr hartem Werkstoff besteht.  



  Drei Ausführungsbeispiele der Erfindung     sind     im folgenden an Hand der     Zeichnung    beschrieben.  Die in     Fig.    1 im Schnitt dargestellte, aus Kunst  stoff, z. B. aus Polyamid, bestehende Laufrolle be  sitzt einen Laufkranz 1, eine Rollenscheibe 2 und  eine Rollennabe 3. Diese weist eine     Ausnehmung    4  auf. Hierin     eingesetzt    sind zwei aus Draht gebogene  Ringe 5 und 6, die nach Art von Sprengringen in  die     Ausnehmung    4 eingesetzt sind. Der Draht selbst  hat dreieckigen Querschnitt mit abgerundeten bzw.       abgeflachten    Kanten.

   Die beiden Ringe bilden die       Laufbahnen    für die Kugeln 7 des Wälzlagers, dessen    innerer Ring mit 8 bezeichnet ist. Er dient gleich  zeitig zur Befestigung der Rolle auf einer nicht wei  ter dargestellten Achse.  



  Das     Ausführungsbeispiel    nach     Fig.    2 zeigt eine  gleich ausgebildete Laufrolle, nur sind die beiden  Ringe 5 und 6 durch ein kreisförmig gebogenes  Band 9 ersetzt, das     gleichfalls    nach Art eines     Spreng-          ringes    in die     Ausnehmung    4     eingesetzt    ist. Das Band  ist im Querschnitt     bogenförmig    gestaltet.  



  Bei dem in     Fig.    3 und 4 im Schnitt und in Seiten  ansicht dargestellten Ausführungsbeispiel hat die  Laufrolle einen     Laufkranz    10, der mit der     Nabe    12  durch mehrere Speichen 11 verbunden ist. Die Nabe  hat ebenfalls eine Aussparung 4. Hierin sitzen zwei  Drahtringe 13 und 14, die wiederum nach     Art    von  Sprengringen in die     Ausnehmung    4     eingesetzt        sind.     Die Rollen des Wälzlagers sind mit 15 und der in  nere Lagerring ist mit 16 bezeichnet. Er ist in An  sicht dargestellt und zeigt die Laufrolle 17 für die  Kugeln 15.  



  Die in     Fig.    1 und 3 dargestellten Drahtringe ha  ben eine solche Lage, dass die Berührungsflächen  der Drahtringe mit den Rollen, also die Laufbahnen  mit der Lagermittellinie, einen Winkel einschliessen,  der wie in     Fig.    1 dargestellt zwischen 30 und     6011     liegt. Die Lagerringe werden so von den Kugeln 7  bzw. 15 in der     Ausnehmung    auch in axialer Rich  tung gegeneinander festgelegt.



      Roller made of plastic It is known to produce rollers made of plastic, for example made of polyamide, and a roller bearing, preferably a ball bearing, in the hub of the roller. to fix. The attachment of the roller bearings in the hub requires additional funds. The rollers are usually designed in two parts in order to be able to enclose the roller bearing between the two parts. Such rollers are relatively expensive to produce.



  According to the invention, the roller bearing equipped with a plastic roller is designed so that the roller hub has a recess for receiving the outer bearing ring of the roller bearing, that the outer diameter of this bearing ring is greater than the inside diameter of the hub and the bearing ring itself from circularly curved There are wires or bands that are inserted into the recess of the roller hub in the manner of snap rings.



  With this design of the hub, additional fastening means are not required and the hub itself can be designed in one piece. However, it has the advantage over the only plastic running rollers that the raceway of the rollers of the rolling bearing is made of very hard material.



  Three exemplary embodiments of the invention are described below with reference to the drawing. The shown in Fig. 1 in section, made of plastic, for. B. made of polyamide, existing roller be seated a tread 1, a pulley 2 and a roller hub 3. This has a recess 4 on. Inserted here are two rings 5 and 6 bent from wire, which are inserted into the recess 4 in the manner of snap rings. The wire itself has a triangular cross-section with rounded or flattened edges.

   The two rings form the raceways for the balls 7 of the roller bearing, the inner ring of which is denoted by 8. It is used at the same time to attach the role on an axis not shown Wei ter.



  The embodiment according to FIG. 2 shows an identically designed roller, only the two rings 5 and 6 are replaced by a circularly curved band 9 which is also inserted into the recess 4 in the manner of a snap ring. The band is curved in cross section.



  In the embodiment shown in Fig. 3 and 4 in section and in side view, the roller has a running ring 10 which is connected to the hub 12 by a plurality of spokes 11. The hub also has a recess 4. Two wire rings 13 and 14 are seated therein, which in turn are inserted into the recess 4 in the manner of snap rings. The rollers of the rolling bearing are denoted by 15 and the bearing ring in nere is denoted by 16. It is shown in perspective and shows the roller 17 for the balls 15.



  The wire rings shown in FIGS. 1 and 3 have such a position that the contact surfaces of the wire rings with the rollers, i.e. the raceways with the bearing center line, enclose an angle which, as shown in FIG. 1, is between 30 and 6011. The bearing rings are set against one another by the balls 7 and 15 in the recess also in the axial direction.
