Description
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung betrifft eine Spannrolle oder Umlenkrolle eines Zugmitteltriebs, die insbesondere mit einem als Riemen ausgebildeten Zugmittel eines Zugmitteltriebs zusammenwirkt. Die Spannrolle oder Umlenkrolle besteht aus einem ein Wälzlager umschließenden Laufmantel, der kraft- und/oder formschlüssig mit einem äußeren Lagerring des Wälzlagers verbunden ist. Zur Darstellung einer definierten Einbaulage ist der Spannrolle oder Umlaufrolle zur Abstützung eine Distanzhülse als separates Bauteil zugeordnet. Die Befestigung der Spannrolle oder Umlenkrolle erfolgt mittels einer Befestigungsschraube, die durch Aufnahmebohrungen des inneren Wälzlagerrings und des sich anschließenden Distanzstücks geführt ist und lösbar in einer Gewindebohrung einer Anschraubfläche verschraubt ist.The The present invention relates to a tension pulley or pulley a traction drive, in particular with a trained as a belt Pulling means of a traction mechanism cooperates. The tensioner or Pulley consists of a rolling bearing enclosing Running jacket, the positive and / or positive fit with an outer Bearing ring of the bearing is connected. To the representation a defined installation position is the tension roller or roller for supporting a spacer sleeve as a separate Assigned component. The attachment of the tension pulley or pulley takes place by means of a fastening screw which passes through receiving bores of inner rolling bearing ring and the subsequent Spacer is guided and detachable is bolted in a threaded bore of a mounting surface.
Hintergrund der ErfindungBackground of the invention
Es ist bekannt, Spannrollen oder Umlenkrollen zur Erzielung einer definierten Einbaulage ein Distanzstück zuzuordnen. Diese bevorzugt als ein Rohrabschnitt ausgebildete Hülse ist im Einbauzustand spannrollenseitig einem Wälzlager der Spannrolle oder Umlenkrolle zugeordnet. Dieser bekannte Aufbau erfordert eine Verliersicherung des Distanzstücks von dem Einbau bzw. der Montage der Spann- oder Umlenkrolle, beispielsweise mittels einer separaten Sicherung.It is known tension rollers or pulleys to achieve a defined Installation position to allocate a spacer. These are preferred formed as a pipe section sleeve is in the installed state tension roller side a roller bearing of the tensioner pulley or pulley assigned. This known structure requires a captive the spacer of the installation or assembly of the clamping or Deflection pulley, for example by means of a separate fuse.

Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt die Aufgabe zu Grunde, ein kostengünstig herstellbares, einfach montierbares und gewichtsoptimiertes Distanzstück zu schaffen.Of the Invention is based on the object, a cost producible, easy to assemble and weight-optimized spacer to accomplish.
Die zuvor genannte Problemstellung wird durch die Merkmale des Anspruchs 1 gelöst. Danach ist das erfindungsgemäße Distanzstück ausschließlich aus Kunststoff hergestellt oder als ein animiertes Kunststoffbauteil gestaltet. Zur Schaffung einer fixierten Einbaulage greift das Distanzstück mit einem hülsenartig gestalteten Abschnitt aus Kunststoff formschlüssig in den inneren Lagerring des Wälzlagers ein. Weiterhin umfasst das erfindungsgemäße Distanzstück eine elastische Verliersicherung der Befestigungsschraube sowie eine ebenfalls aus Kunststoff hergestellte scheibenartig ausgeführte Vordichtung, welche das Wälzlager stirnseitig abdeckt. Vorteilhaft bietet das erfindungsgemäße Distanzstück eine deutliche Gewichtsreduzierung und benötigt keinen separaten Arbeitsgang, um eine wirksame Verliersicherung für die Befestigungsschraube zu erreichen.The The aforementioned problem is solved by the features of the claim 1 solved. Thereafter, the inventive Spacer made exclusively of plastic or designed as an animated plastic component. To create a fixed mounting position engages with the spacer a sleeve-like designed section of plastic a positive fit in the inner bearing ring of the bearing. Furthermore, the spacer according to the invention comprises an elastic captive securing the fastening screw as well a likewise made of plastic disc-like executed Pre-seal, which covers the roller bearing frontally. Advantageously, the spacer according to the invention provides a significant weight reduction and does not require a separate Operation in order to provide effective captive protection for the To reach fastening screw.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche 2 bis 9.Further advantageous embodiments of the invention are the subject of the dependent Claims 2 to 9.
Ein bevorzugter Aufbau sieht vor, dass ein ringförmiger Druck belastbarer Abschnitt des erfindungsgemäßen Distanzstück unmittelbar an einer Stirnseite des inneren Lagerrings des Wälzlagers abgestützt ist. Durch diese Maßnahme wird beim Anziehen der Befestigungsschraube eine geradlinige Krafteinleitung von dem inneren Lagerring über das Distanzstück in die Abstützfläche der Spann- oder Umlenkrolle erzielt.One preferred structure provides that an annular pressure resilient section of the spacer according to the invention directly on an end face of the inner bearing ring of the rolling bearing is supported. This measure is the Tighten the fastening screw a straight-line force application from the inner bearing ring via the spacer in the support surface of the tensioning or deflection roller achieved.
Zur Sicherung der Befestigungsschraube ist innerhalb der Aufnahmebohrung des Distanzstücks ein elastisch ausgeführter, an dem Schaft der Befestigungsschraube abgestützter Schnappkragen aus Kunststoff vorgesehen. Dazu bietet es sich an, den Kragen geschlitzt auszuführen oder lokal umfangsverteilt angeordnete Kunststoff-Schnappnasen vorzusehen, zur Schaffung einer verliergesicherten Befestigungsschraube.to Securing the fastening screw is within the mounting hole of the spacer an elastically executed, on the shaft of the fastening screw supported snap collar made of plastic. It is advisable to slit the collar execute or locally circumferentially distributed arranged plastic snap noses to provide, to create a secure fastening screw.
Als Armierung ist bevorzugt eine sich über die gesamte Breite des Distanzstücks erstreckende Hülse aus Metall vorgesehen, die vom Kunststoff umspritzt und im Einbauzustand unmittelbar an einer Stirnseite des inneren Lagerrings abgestützt ist. Zur Schaffung einer wirksamen formschlüssigen Verbindung weist die als Armierung dienende Hülse lokale Ausnehmungen oder Durchbrüche auf, wie beim Herstellungsverfahren, insbesondere einem Kunststoff-Spritzgussverfahren von dem Kunststoff ausgefüllt werden.When Reinforcement is preferably one across the entire width the spacer extending sleeve of metal provided, which is encapsulated by the plastic and in the installed state immediately is supported on an end face of the inner bearing ring. To create an effective positive connection has the serving as a reinforcement sleeve local recesses or breakthroughs, as in the manufacturing process, in particular a plastic injection molding of the plastic filled become.
Zur Anpassung der Vordichtung des Distanzstücks an die stirnseitige Kontur des Wälzlagers und der Nabe des Laufmantels ist die Vordichtung in radialer Richtung gestuft gestaltet und verläuft dabei relativ eng beabstandet zu der jeweiligen Wälzlager- bzw. Laufring-Kontur. Vorzugsweise bildet die Vordichtung außenseitig einen rechtwinklig zu dem Laufmantel ausgerichteten Bord, der die Nabe des Laufmantels zur Bildung eines Dichtungslabyrinths bereichsweise eng beabstandet umgreift.To adapt the pre-seal of the spacer to the frontal contour of the rolling bearing and the hub of the barrel jacket, the pre-seal is stepped stepped in the radial direction and extends relatively closely spaced to the respective Wälzlager- or raceway contour. Preferably, the pre-seal on the outside forms a perpendicular to the running jacket aligned board, be the hub of the running jacket to form a seal labyrinth be richly closely spaced surrounds.
Als Kunststoff für das Distanzstück ist bevorzugt ein Polymer oder ein vergleichbarer, die geforderte Festigkeit und Temperaturbeständigkeit erfüllender Kunststoff vorgesehen. Als Werkstoff für die Armierung eignet sich ein aus Aluminium oder Stahl ausgeführte Hülse.When Plastic for the spacer is preferred a polymer or a comparable, the required strength and Temperature resistance fulfilling plastic intended. As a material for the reinforcement is suitable a sleeve made of aluminum or steel.
