Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft eine Befestigungsvorrichtung für eine Riemenrolle mit einer Befestigungsschraube, die durch eine Lagerbohrung eines Innenrin­ ges eines Wälzlagers geführt ist und die Mittel zu ihrer Transportsicherung aufweist.The invention relates to a fastening device for a belt roller a mounting screw through a bearing hole in an inner ring is guided by a rolling bearing and the means for securing it in transit having.

Hintergrund der ErfindungBackground of the Invention

Eine solche gattungsgemäße Befestigungsvorrichtung für Riemenrollen ist aus der deutschen Gebrauchsmusteranmeldung DE 297 20 776 U1 vorbe­ kannt. Die in den Fig. 1 und 2 dargestellten Riemenrollen bestehen im wesentlichen aus einem abgedichteten Kugellager, einem aus Kunststoff angeformten Laufmantel und einer Befestigungseinrichtung. Diese setzt sich aus einer Schraube und einer Dichtscheibe zusammen, die das Kugel­ lager gegen Spritzwasser und harte Partikel schützt. Sie ist aus einer ebe­ nen Blechscheibe gefertigt, deren äußerer Umfang mit der Nabe des Lauf­ mantels eine Labyrinthdichtung bildet. Im Zentrum ist eine topfförmige Durchprägung vorgesehen, die mit ihrem Mantel in die Bohrung des Innen­ ringes eingepreßt ist. Eine zentrale Bohrung nimmt den Schaft der Befesti­ gungsschraube auf, deren Kopf im Bereich der Seitenfläche des Innenrin­ ges unter Zwischenlage der Dichtscheibe aufliegt. Ein sich an den Kopf anschließender Schaftabschnitt der Befestigungsschraube weist einen grö­ ßeren Durchmesser auf, der diese gegenüber dem Innenring zentriert.Such a generic fastening device for belt pulleys is known from German utility model application DE 297 20 776 U1. The belt rollers shown in FIGS . 1 and 2 consist essentially of a sealed ball bearing, a molded plastic barrel jacket and a fastening device. This consists of a screw and a sealing washer that protects the ball bearing against splash water and hard particles. It is made of a flat sheet metal disc, the outer circumference of which forms a labyrinth seal with the hub of the barrel jacket. In the center, a pot-shaped embossment is provided, which is pressed with its jacket into the bore of the inner ring. A central hole receives the shank of the fastening screw, the head of which rests in the area of the side surface of the inner ring with the sealing washer in between. A shaft section of the fastening screw adjoining the head has a larger diameter which centers it with respect to the inner ring.

Nachteilig dabei ist, daß Dichtscheibe und Befestigungsmittel als ein ein­ stückiges Bauteil ausgebildet sind, das aufgrund seiner komplizierten Formgebung nur relativ teuer herstellbar ist. Ein weiterer Nachteil liegt dar­ in, daß die Befestigungsschraube in der Lagerbohrung nicht durch diese, sondern über den Umweg der Dichtscheibe zentriert ist.The disadvantage here is that the sealing washer and fasteners as one lumpy component are formed, which due to its complicated Shaping is relatively expensive to manufacture. Another disadvantage is in that the mounting screw in the bearing bore is not through this, but centered on the detour of the sealing washer.

Zusammenfassung der ErfindungSummary of the invention

Aufgabe der Erfindung ist es daher, eine Befestigungsvorrichtung für eine Riemenrolle zu schaffen, die sich einfach herstellen und handhaben läßt.The object of the invention is therefore a fastening device for a To create belt roll that is easy to manufacture and handle.

Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 dadurch gelöst, daß die Transportsicherung durch einen ge­ schlitzten in seinem Durchmesser veränderbaren Haltering gebildet ist, des­ sen Außendurchmesser im nichteingesetzten Zustand größer als der Durchmesser der Lagerbohrung ist und der unter Vorspannung in die La­ gerbohrung eingesetzt ist, wobei er mit seiner Aufnahmebohrung einen Freistich der Befestigungsschraube umschließt.According to the invention, this task is performed according to the characterizing part of Claim 1 solved in that the transport lock by a ge slotted retaining ring is formed in its diameter, the sen outside diameter when not in use larger than that Diameter of the bearing bore and the preload in the La gerbohrung is used, with its receiving bore Undercut of the fastening screw encloses.

Der wesentliche Vorteil gegenüber dem bisherigen Stand der Technik liegt darin, daß der Haltering als konstruktiv einfach gestaltetes Bauteil ohne nennenswerten Aufwand herstellbar und auch in einfacher Weise handhab­ bar ist.The main advantage over the prior art is in that the retaining ring as a structurally simple component without significant effort to produce and easy to handle is cash.

Eine wesentliche Verstärkung der Haltekraft wird nach Anspruch 2 dadurch erreicht, daß der Haltering im eingesetzten Zustand den Freistich der Befe­ stigungsschraube unter elastischer oder plastischer Verformung seiner Auf­ nahmebohrung umschließt.A substantial increase in the holding force is thereby according to claim 2 achieved that the retaining ring in the inserted state the undercut of the Befe setting screw under elastic or plastic deformation of its up receiving hole encloses.

Nach einem weiteren Merkmal der Erfindung gemäß Anspruch 3 soll der Haltering wenigstens an seiner äußeren Umfangsfläche federnde Haltevor­ sprünge aufweisen. Durch diese Haltevorsprünge ist sichergestellt, daß sich der Haltering leichter in die Lagerbohrung einsetzen läßt.According to a further feature of the invention according to claim 3, the  Retaining ring resilient at least on its outer peripheral surface have cracks. These holding projections ensure that the retaining ring can be inserted more easily into the bearing bore.

In vorteilhafter Weise ist nach Anspruch 4 vorgesehen, daß der Haltering aus einem polymeren Werkstoff, vorzugsweise aus Polyamid, gefertigt sein soll. Polyamid als thermoplastischer Kunststoff zeichnet sich vor allem durch hervorragende mechanische Eigenschaften aus, wobei insbesondere eine gute Formbeständigkeit in der Wärme und die Beständigkeit gegen­ über Treib- und Schmierstoffen in den Vordergrund zu stellen sind.It is advantageously provided according to claim 4 that the retaining ring be made of a polymeric material, preferably polyamide should. Polyamide as a thermoplastic material stands out above all characterized by excellent mechanical properties, in particular good dimensional stability under heat and resistance to focus on fuels and lubricants.

Schließlich soll nach Anspruch 5 zwischen einem Kopf der Befestigungs­ schraube und dem Innenring des Wälzlagers eine dieses abdeckende Dichtscheibe eingespannt sein, so daß das Wälzlager aufgrund der so ent­ stehenden Spaltdichtung besonders wirkungsvoll vor Schmutz geschützt ist.Finally, according to claim 5 between a head of attachment screw and the inner ring of the rolling bearing covering this Sealing washer clamped so that the roller bearing due to the ent standing gap seal is particularly effectively protected from dirt.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below using an exemplary embodiment explained.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings

Die in Fig. 1 dargestellte Bandspannrolle besteht im wesentlichen aus einem abgedichteten Kugellager 1, dessen äußerer Lagerring 2 als Laufflä­ che für einen nicht dargestellten Riemen dient. Rechtsseitig ist zwischen der Stirnfläche des inneren Lagerringes 3 und einem Kopf 4 einer Befesti­ gungsschraube 5 eine Dichtscheibe 6 eingespannt, die mit der nicht näher bezeichneten Lagerdichtung bzw. dem äußeren Lagerring 2 eine Spalt­ dichtung bildet. Die Befestigungsschraube 5 weist einen Schaftabschnitt 7 mit einem größeren Durchmesser auf, der die Schraube 5 gegenüber dem Innenring 3 zentriert. Zwischen dem Schaftabschnitt 7 und einem Gewinde­ abschnitt 8 weist die Befestigungsschraube 5 einen Freistich 9 auf, der einen kleineren Durchmesser als der Gewindeabschnitt 8 besitzt. Der Freistich 9 wird nun von einem Haltering 10 umfaßt, der mit seiner Außenmantelfläche unter Vorspannung in der Lagerbohrung anliegt. Auf diese Weise ist sicher­ gestellt, daß die Befestigungsschraube 5 in der Lagerbohrung frei drehbar, jedoch axial gegen Herausfallen gesichert untergebracht ist.The belt tensioning roller shown in Fig. 1 consists essentially of a sealed ball bearing 1 , the outer bearing ring 2 serves as a Laufflä surface for a belt, not shown. On the right-hand side, a sealing washer 6 is clamped between the end face of the inner bearing ring 3 and a head 4 of a fastening screw 5 , which forms a gap seal with the unspecified bearing seal or the outer bearing ring 2 . The fastening screw 5 has a shaft section 7 with a larger diameter, which centers the screw 5 with respect to the inner ring 3 . Between the shaft section 7 and a threaded section 8 , the fastening screw 5 has an undercut 9 , which has a smaller diameter than the threaded section 8 . The undercut 9 is now encompassed by a retaining ring 10 , which rests with its outer lateral surface under prestress in the bearing bore. In this way it is ensured that the fastening screw 5 is freely rotatable in the bearing bore, but is axially secured against falling out.

Der in den Fig. 2 und 3 einzeln mit dem äußeren Durchmesser D darge­ stellte Haltering 10 ist mit einem Schlitz versehen, dessen Maulweite s nur geringfügig kleiner als der innere Durchmesser d der Aufnahmebohrung ist. Ein derartig gestalteter Haltering 10 macht es in einfacher Weise möglich, daß er sowohl aufgeweitet als auch zusammengepreßt werden kann. Die radialen Größenverhältnisse des Halteringes 10 müssen also so aufeinan­ der abgestimmt sein, daß er im eingesetzten Zustand einerseits sicher unter Vorspannung in der Lagerbohrung gehalten ist und daß er andererseits den Freistich der Befestigungsschraube 5 so umschließt, daß diese axial nicht herausgezogen werden kann. The in Fig. 2 and 3 individually with the outer diameter D Darge presented retaining ring 10 is provided with a slot, the mouth width s is only slightly smaller than the inner diameter d of the receiving bore. Such a retaining ring 10 makes it possible in a simple manner that it can be expanded as well as pressed together. The radial proportions of the retaining ring 10 must therefore be matched to one another so that in the inserted state it is securely held under tension in the bearing bore on the one hand and that it surrounds the undercut of the fastening screw 5 so that it cannot be pulled out axially.
