Abstract
Vorgeschlagen ist eine Riemenrolle (1, 1') für einen Riementrieb eines Verbrennungsmotors, umfassend: – eine Riemenscheibe (3), – ein Wälzlager mit einem die Riemenscheibe teilweise oder vollständig bildenden Außenring (2) und mit einem am Verbrennungsmotor befestigten Innenring (7), – und eine die Bohrung (6) des Innenrings durchsetzende Schraube (5) zur Befestigung des Innenrings am Verbrennungsmotor. Der Innenring soll axial und umfänglich unlösbar fest mit der Schraube verbunden sein.Proposed is a belt pulley (1, 1 ') for a belt drive of an internal combustion engine, comprising: - a pulley (3), - a roller bearing with an outer ring (2) partially or completely forming the pulley and with an inner ring (7) attached to the combustion engine , - And a bore (6) of the inner ring passing through screw (5) for fixing the inner ring on the internal combustion engine. The inner ring should be axially and circumferentially permanently connected to the screw.
Description
Die Erfindung betrifft eine Riemenrolle für einen Riementrieb eines Verbrennungsmotors. Die Riemenrolle umfasst:
- – eine Riemenscheibe,
- – ein Wälzlager mit einem die Riemenscheibe teilweise oder vollständig bildenden Außenring und mit einem am Verbrennungsmotor befestigten Innenring,
- – und eine die Bohrung des Innenrings durchsetzende Schraube zur Befestigung des Innenrings am Verbrennungsmotor.
- A pulley,
- A rolling bearing with an outer ring partially or wholly forming the pulley and with an inner ring fixed to the internal combustion engine,
- - And a bore of the inner ring passing through screw for fixing the inner ring on the engine.
Hintergrund der ErfindungBackground of the invention
Eine derartige Riemenrolle dient zum Umlenken des Riemens und ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Riemenrolle der eingangs genannten Art konstruktiv zu vereinfachen.The present invention has for its object to simplify a belt pulley of the type mentioned constructive.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind den abhängigen Ansprüchen entnehmbar. Demnach soll der Innenring axial und umfänglich unlösbar fest mit der Schraube verbunden sein. Somit sind der Innenring und die Schraube zu einem in sich starren Bauteil zusammengefasst und relativ zueinander weder verdrehbar noch verschiebbar. Dabei können die bislang erforderlichen Komponenten zum axialen Fixieren der Schraube im Innenring zugunsten der verringerten Bauteilanzahl der Riemenrolle entfallen.The solution to this problem arises from the features of claim 1. Advantageous developments and refinements of the invention can be taken from the dependent claims. Accordingly, the inner ring should be axially and circumferentially permanently connected to the screw. Thus, the inner ring and the screw are combined into a rigid component and relative to each other neither rotated nor displaced. In this case, the previously required components for axial fixing of the screw in the inner ring in favor of the reduced number of components of the belt roll can be omitted.
Unter dem Begriff "unlösbar fest" ist selbstverständlich zu verstehen, dass die aneinander befestigten Teile nur unter Zerstörung voneinander gelöst werden können.The term "permanently fixed" is to be understood, of course, that the parts attached to each other can only be solved by destroying each other.
Kurze Beschreibung der ZeichnungenBrief description of the drawings
Weitere Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus den Zeichnungen, in denen zwei Ausführungsbeispiele erfindungsgemäßer Riemenrollen mit unterschiedlichem Abstand zum Motorblock des Verbrennungsmotors jeweils im Längsschnitt dargestellt sind. Sofern nicht anders erwähnt, sind dabei gleiche oder funktionsgleiche Merkmale oder Bauteile mit gleichen Bezugszahlen versehen. Es zeigen:Further features of the invention will become apparent from the following description and from the drawings, in which two embodiments of inventive belt rollers are shown with different distances to the engine block of the internal combustion engine in each case in longitudinal section. Unless otherwise stated, the same or functionally identical features or components are provided with the same reference numbers. Show it:
