Description

Beiestigungsvorrichtung für NabenAttachment device for hubs

Die Erfind ong bezieht sich auf eine Vorrichtung zum Befestigen von Naben, insbesondere von Wälzlagern, auf einer Welle, wobei zwischen der konischen Bohrung der Nabe bzw. des Wälzlagers und der -sylin&risehen Mantelfläche der Welle eine Spannhülse rvit entsprechend konischem fSantelfläche und zylindrischer Bohrung vorgesehen ist, auf eieren Stirnseite geringeren Außendurchmessers eine die Nabe bzw. das Wälzlager auf die Spannhülse drückende Spannmutter aufgeschraubt ist. Zwischen Spannmutter und benachbarter Naben- bzw. Wälzlagerstirnfläche ist in der Regel ein ringförmiges Sicherungsblech vorgesehen.The invent ong relates to a device for Fastening hubs, in particular rolling bearings, on a shaft, with the hub or the conical bore between the Rolling bearing and the -sylin & risehen outer surface of the shaft Clamping sleeve rvit correspondingly conical and cylindrical Bore is provided on a lower face Outer diameter a the hub or the roller bearing is screwed onto the clamping sleeve pressing clamping nut. Between An annular locking plate is usually provided for the clamping nut and the adjacent hub or roller bearing face.

Derartige Befestigungsvorrichtungen fCL? N^.bei. "'" ^r Wälzlager an beliebiger Stelle einer zylindrische^ ;i. Jind bekannt. Nachteilig bei ihnen ist, daß die SpannhiJ -~ als massives Bauteil ausgebildet und daher aufwendig ■ usr Herstellung und verhältnismäßig teuer ist, was insbesondere bei einem derartigen Massenprodukt ins Gewicht fällt. Dies trifft auch bei den bekannten Befestigungsvorrichtungen für Wälzlager mit zylindrischer Bohrung auf einer zylindrischen Welle zu, die aus mindestens zwei ringförmigen, übereinander angeordneten Teilen mit konischen gegenseitigen Berührungsflächen bestehen, welche zwischen Wälzlager und Welle verspannt sind, und zwar entweder durch gegenseitiges Aufschrauben oder mit Hilfe einer auf dieSuch fastening devices fCL?

The disadvantage with them is that the clamping device is designed as a solid component and is therefore complex to manufacture and relatively expensive, which is particularly important in the case of such a mass product. This also applies to the known fastening devices for rolling bearings with a cylindrical bore on a cylindrical shaft, which consist of at least two ring-shaped, superimposed parts with conical mutual contact surfaces, which are braced between the rolling bearing and the shaft, either by screwing them on each other or with the aid one on the

Innenhülse aufgeschraubten Spannmutter, welche am Wälzlager anliegt, oder durch Madenschrauben, welche gegen die Welle festgezogen sind.Inner sleeve screwed on clamping nut, which rests on the roller bearing, or by grub screws, which against the shaft are tightened.

Aufgabe der Erfindung ist es, diese Nachteile zu beheben und eine Vorrichtung der eingangs angegebenen Art zu schaffen, die bei gleichem Platzbedarf und ebenso einfacher Montier- und Demontierbarkeit billiger in der Herstellung ist. Dies ist erfindungsgemäß dadurch erreicht, daß die Spannhülse aus einer zylindrischen, spanlos geformten, dünnwandigen und axial geschlitzten Innenhülse mit umgebördelter Ringschulter an einer und einem Außengewinde für die Spannmutter an der anderen Stirnseite, sowie aus einem federnden Ringteil mit konischer Mantelfläche uc.d zylindrischer Bohrung auf der Hülse besteht.The object of the invention is to eliminate these disadvantages and to provide a device of the type specified at the beginning create that is cheaper to manufacture with the same space requirements and just as easy assembly and disassembly. This is achieved according to the invention in that the clamping sleeve made of a cylindrical, non-cutting, thin-walled and axially slotted inner sleeve with a flanged ring shoulder on one and an external thread for the clamping nut on the other face, as well as from a resilient ring part with a conical Outer surface uc.d cylindrical bore on the sleeve.

Vorzugsweise besteht das federnde Ringteil aus leicht verformbarem Material, insbesondere aus glasfaserverstärktem Kunststoff. Zusätzlich oder stattdessen kann dps Ringteil zur besseren Federung mindestens einen Axialschlitz aufweisen. Der Schlitz kann axial durchgehend sein. Sind mehrere Schlitze vorgesehen, dann durchsetzen sie das Ringteil bzw. die Innenhülse vorteilhafterweise nicht arf der gesamten Breite, abgesehen von gegebenenfalls einem axialen Schlitz.The resilient ring part preferably consists of an easily deformable material, in particular of glass fiber reinforced material Plastic. Additionally or instead of this, dps ring part can be used better suspension have at least one axial slot. The slot can be axially continuous. Are multiple slots provided, then they penetrate the ring part or the inner sleeve advantageously not arf the entire width, apart from possibly an axial slot.

Eine weitere Verbilligung ergibt sich dann, wenn das Außengewinde auf die Innenhülse aufgerollt ist.A further reduction in price results when the external thread is rolled onto the inner sleeve.

Nachstehend ist eine Ausführungsform der Erfindung anhand der beigefügton Zeichnung beispielsweisa beschrieben, deren einzige Figur die Ansicht der oberen Eälfte eines Axialschnitts durch eine erfindungsgemäße Befestigungsvorrichtung zeigt, welche ein Radialrixlenkugellager auf einer Welle festlegt.An embodiment of the invention is described by way of example with reference to the accompanying drawing, of which single figure shows the view of the upper half of an axial section through a fastening device according to the invention shows, which fixes a radial Rix ball bearing on a shaft.

Auf der zylindrischen Welle 1 ist der Innenring 2 des Radialrillenkugellagers 3 mit Hilfe einer erfindungsgemäßen Befestigungsvorrichtung festgelegt. Die Bohrung des TnJiCiiririSjC 2 Int Ivonis^il »»epoh-inriet TH ρ Vn-p-r-i nhtnnp- "hpRirpht; aus einer spanlos geformten Innenhülse 4, die an einer Stirnseite zur axialen Abstützung eine radial nach außen umgebördelte Ringschulter 5 aufweist. An der anderen Stirnseite ist ein Außengewinde 6 für eine Spannfutter 7 aufgerollt. Zwischen der zylindrischen Innenhülse M- und der konischen Bohrung 8 des Innenrings 2 ist ein Ringteil 9 mit konischer Mantelfläche und zylindrischer Bohrung vorgesehen.The inner ring 2 of the radial deep groove ball bearing 3 is fixed on the cylindrical shaft 1 with the aid of a fastening device according to the invention. The bore of the TnJiCiiririSjC 2 Int Ivonis ^ il »» epoh-inriet TH ρ Vn-pri nhtnnp- "hpRirpht; from a non-cutting inner sleeve 4, which has a radially outwardly flanged annular shoulder 5 on one end face for axial support. On the other On the end face, an external thread 6 is rolled up for a chuck 7. Between the cylindrical inner sleeve M and the conical bore 8 of the inner ring 2, a ring part 9 with a conical jacket surface and a cylindrical bore is provided.

Die Innenhülse 4 weist einen durchlaufenden Axialschlitz 10 auf. Beim Anziehen der Spannfutter 7 wird das Ringteil 9 in die kegelige Bohrung 8 des Innenrings 2 eingepreßt i und z-war unter gleichzeitiger Durchmesserverminderung der Innenhülse 4 aufgrund des Schlitzes 10. Auf diese Weise wird ein Festsitζ auf der Welle Λ erreicht.The inner sleeve 4 has a continuous axial slot 10. When tightening the chuck 7, the ring part 9 is pressed i and z-war into the tapered bore 8 of the inner ring 2 with a simultaneous diameter reduction of the inner sleeve 4 due to the slot 10. In this way, a Festsitζ on the shaft Λ is achieved.

Bei Verwendung eines ungeschlitzten Eingteils 9 ist es vorteilhaft, wenn das Teil 9 aus leicht verformbarem Werkstoff besteht. Besonders geeignet ist glaserfaserverstärkter Kunststoff. Ein Ausweichen des Kunststoffs beim Festziehen der Vorrichtung ist einerseits durch die Ringschulter 5 der Innenhülse 4, andererseits durch die Spannmutt^r 7 mit dem ringförmigen Sicherungsblech 11 verhindert.When using an unslotted integral part 9 is it is advantageous if the part 9 is made of easily deformable Material. Glass fiber reinforced plastic is particularly suitable. Dodging the plastic when The device is tightened on the one hand by the annular shoulder 5 of the inner sleeve 4 and on the other hand by the clamping nut ^ r 7 prevented with the annular locking plate 11.
