Abstract

The sprocket is assembled from component parts. A material strip deformed into a toothed profile and forming a ring (4) is fitted concentrically with the wheel hub (2) between two circular disks (1, 6). there are guide grooves (3) in the disks for the material strip. The hub is on one of the disks and the other is in the form of a ring.

Description

Bisher sind Zahnriemenräder aus einem Stück bekannt. So ist in der OS 33 07 391 A1 "Kraftübertragungsrad" ein aus Kunststoff geformtes Zahnriemenrad mit einem konzentrisch im Abstand zur Nabe angeordneten Zahnkranz beschrieben ist. Die Fertigung solcher Zahnriemenräder ist relativ materialaufwendig.To date, toothed belt wheels made of one piece are known. This is the case in OS 33 07 391 A1 "Power transmission wheel" is a plastic belt pulley with a concentric spaced from the hub sprocket is described. The manufacture of such Toothed belt wheels are relatively expensive.

Aus DE 89 09 052 U1 ist eine Zahnriemenscheibe bekannt, die einen Zahnkranz mit radial am Umfang nach außen gerichteten Zähnen mit dazwischen liegenden Lücken hat, wobei in die Lücken seitliche Führungsring eingreifen. Auch hier wird ein aus einem Stück hergestelltes Zahnrad durch Ansetzen von Führungsscheiben verstärkt, so daß der Fertigungsaufwand, abgesehen von der Einpaßarbeit gesteigert wird.From DE 89 09 052 U1 a toothed belt pulley is known which has a ring gear with a radial on Has circumferentially outward teeth with gaps in between, being in the Engage gaps in the side guide ring. Again, one is made from one piece Gear wheel reinforced by attaching guide washers, so that the manufacturing effort, apart from the fitting work is increased.

Ziel und Aufgabe der Erfindung ist es, ein aus Teilen zusammengefügtes Zahnriemenrad zu finden, das einfach in verschiedenen Dimensionen gefertigt wird.The aim and object of the invention is to provide a toothed belt wheel assembled from parts find that is simply manufactured in different dimensions.

Die Lösung dieser Aufgabe ist Gegenstand der im ersten Anspruch offenbarten Erfindung. Weitere zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The solution to this problem is the subject of the invention disclosed in the first claim. Further expedient refinements of the invention are the subject of the dependent claims.

Das aus mehreren Teilen zusammengefügte Zahnriemenrad besteht aus zwischen zwei Kreisscheiben einem zu einem Zahnprofil umgeformter Materialstreifen als Materialstreifenring eingefügt ist. In die Kreisscheiben können Führungsnuten für den Materialstreifen eingesenkt sein. Eine Kreisscheibe kann die Radnabe tragen. Die Gegenscheibe kann ein Kreisring mit mittleren dem Materialstreifenring entsprechenden Durchmesser sein.The toothed belt wheel, which is composed of several parts, consists of two Circular discs of a material strip formed into a tooth profile as a material strip ring is inserted. Guide grooves for the material strip can be sunk into the circular disks his. A circular disc can support the wheel hub. The counter disc can have a circular ring average diameter corresponding to the material strip ring.

Die Erfindung soll nachstehend an Hand eines Ausführungsbeispiels näher erläutert werden. Die zugehörige Zeichnung zeigt eine Explosivdarstellung des Zahnriemenrades.The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows an exploded view of the toothed belt wheel.

In eine Kreisscheibe 1, die eine Nabe 2 trägt, ist eine Führungsnut 3 (verdeckt) eingesenkt. In die Führungsnut 3 greift ein zu einem Materialstreifenring 4 gebogener, zu einem Zahnprofil 5 umgeformter Materialstreifen ein. Der Kreisscheibe 1 gegenüber befindet sich eine zu einem Kreisring 6 geformte zweite Kreisscheibe. In diesen Kreisring ist eine weitere Führungsnut 7 eingesenkt.In a circular disc 1 , which carries a hub 2 , a guide groove 3 (hidden) is sunk. In the guide groove 3, a bent strip of material to a ring 4, reshaped to a tooth profile 5 strip of material engages. Opposite the circular disc 1 is a second circular disc shaped into a circular ring 6 . A further guide groove 7 is sunk into this circular ring.

Der Materialstreifen wird zu einem Zahnprofil 5 umgeformt und zu einem Materialstreifenring 4 gebogen. Dieser Materialstreifenring 4 wird in die Führungsnut 3 eingefügt und durch den Kreisring 6 als Gegenscheibe stabilisiert. The material strip is formed into a tooth profile 5 and bent into a material strip ring 4 . This strip of material ring 4 is inserted into the guide groove 3 and stabilized by the circular ring 6 as a counter plate.
