Abstract

The flywheel hub is fixed to a shaft union by tension bolts, and is centred by means of fitting bending bushes (4) around the tension bolts (6). These bushes have constrictions between the fitting points in the flywheel hub (8) and in the shaft union (3). Clearance exists between the tension bolts (6) and the bushes so that the location of the tension bolts (6) is achieved in the flywheel hub (8) and/or the shaft union (3) via discs (5). The flywheel (1) is divided, and is located on both sides of the shaft union (3). The fitment points of the bending bushes are arranged in the centre of each flywheel hub (8) and in the shaft union (3).

Description

Schwungradbefestigung Die Erfindung bezieht sich auf eine Schwungradbefestigung, insbesondere für Sofortreserveaggregate mit Speicherschwungrad, bei der die Schwungradnabe mittels Spannschrauben an einem Wellenbund befestigt und mittels Passung zentriert ist. Flywheel attachment The invention relates to a flywheel attachment, especially for immediate reserve units with storage flywheels, in which the flywheel hub attached to a shaft collar by means of clamping screws and centered by means of a fit is.

Es ist bekannt, das Speicherschwungrad auf der Welle mittels Dehnschrauben und Zentrierung in Form einer Spielpassung zu befeRigen. Das Spiel in der Passung zwischen Welle und Speicherrad ist fUr die Montage unbedingt erforderlich. Da sich die Schwungscheiben mit zunehmender Drehzahl jedoch am Innendurchmesser aufweiten, entsteht ein unerwünscht großes Spiel in der Passung. Hierdurch kann sich das Speicherrad besonders bei ungleichmäßig angezogenen Dehnschrauben oder ungleichmäßigen Oberflächen an den BerUhrungsflächen von Schwungrad und Wellenbund radial verlagern, was zu unzulässig großen Unwuchten führt.It is known that the storage flywheel on the shaft by means of expansion screws and centering in the form of a clearance fit. The play in the fit between the shaft and the storage wheel is essential for assembly. That I However, the flywheels widen at the inner diameter with increasing speed, there is an undesirably large amount of play in the fit. This can cause the storage wheel especially with unevenly tightened expansion screws or uneven surfaces shift radially at the contact surfaces of the flywheel and shaft collar, which leads to leads to inadmissibly large imbalances.

Der Erfindung liegt die Aufgabe zugrunde, an Sofortreserveaggregaten mit Speicherschwungrad vorstehend beschriebene Schwierigkeiten zu verhindern, wobei insbesondere Probleme bei Montage, Auswuchten und Zentrierung vermieden werden sollen.The invention is based on the task of immediate reserve units with storage flywheel to prevent difficulties described above, wherein in particular problems with assembly, balancing and centering should be avoided.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Passung durch Paßbiegebuchsen erfolgt, die um die Spannschrauben angeordnet sind. Diese Ausgestaltung einer Schwungradbefestigung setzt nicht das Vorhandensein einer umfangreichen Montagevorrichtung vorraus. Das Speicherschwungrad, welches von den Paßbiegebuchsen und nicht am Innendurchmesser der Scheibe zentriert wird, behält seine ursprüngliche Lage auch bei der Aufweitung des Innendurchmessers bei, so daß keine radiale Verlagerung des Speicherschwungrades und eine damit verbundene Unwucht auftritt.The object is achieved according to the invention in that the fit through Bending bushes takes place, which are arranged around the clamping screws. This design a flywheel mount does not require the presence of extensive mounting equipment ahead. The storage flywheel, which is from the fitting bend bushings and not on the inner diameter the disc is centered, retains its original position even when it is widened of the inside diameter, so that no radial displacement of the storage flywheel and an associated imbalance occurs.

Es wird außerdem vorgeschlagen, daß die Paßbiegebuchsen zwischen den Paßstellen in der Schwungradnabe und im Wellenbund Einschnürungen aufweisen. Diese Einschntirungen sind so angeordnet, daß sich nach erfolgter Montage des Speicherschwungrades Paß stellen Jeweils in den Bohrungen von Wellenbund und Schwungradnabe befinden.It is also proposed that the fitting bend bushings between the Have constrictions in the flywheel hub and in the shaft collar. These Restrictions are arranged so that after assembly of the storage flywheel pass each in the bores of the shaft collar and Flywheel hub.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß zwischen den Spannschrauben und Paßbiegebuchsen Spiel vorgesehen ist, wobei die Lagerung der Spannschrauben über Scheiben in der Schwungradnabe und/oder dem Wellenbund erfolgt. Aufgrund der Einschnürungen zwischen den Paßstellen der Paßbiegebuchsen sowie des Spiels zwischen Paßbiegebuchsen und Spannschrauben sowie Scheiben wird die bei großer Drehzahl auftretende Aufweitung der Schwungradnabe berücksichtigt und von den Paßbiegebuchsen als Biege- und nicht als Scherkräfte aufgenommen. Von einer Verbiegung bleiben die Spannschrauben Jedoch unberührt. Weiter wird vorgeschlagen, daß das Schwungrad geteilt ist und an beiden Seiten des Wellenbundes anliegt, daß die Paßstellen der Paßbiegebuchen etwa in der Mitb Jeder Schwungradnabe und des Wellenbundes angeordnet sind und daß die Scheiben in Erweiterungsbohrungen der Schwungradnabe versenkt eingesetzt sind.Another embodiment of the invention provides that between the Tensioning screws and fitting bending bushings are provided, with the storage of the Tensioning screws are carried out via washers in the flywheel hub and / or the shaft collar. Due to the constrictions between the fitting points of the fitting bending bushes and the The clearance between the fitting bushings and the tensioning screws as well as the washers is the larger Speed occurring expansion of the flywheel hub is taken into account and of the fitting bending bushes recorded as bending and not as shear forces. They remain from a bend Turnbuckles, however, unaffected. It is also proposed that the flywheel be divided is and rests on both sides of the shaft collar that the pass points of the pass bends are arranged approximately in the Mitb of each flywheel hub and the shaft collar and that the slices in Countersunk expansion holes in the flywheel hub are used.

Zur weiteren Erläuterung ist ein Ausführungsbeispiel der Erfindung dargestellt.For further explanation is an embodiment of the invention shown.

In der Abbildung sind mit 1 zwei Schwungradhälften bezeichnet, die auf einer Welle 2 angeordnet sind und dabei mit ihren Schwungradnaben 8 an einem Wellenbund 3 anliegen. Durch Paßbohrungen 9 in den Schwungradnaben 8 und im Wellenbund 3 sind Paßbiegebuchsen 4 geführt. In den Schwungradnaben 8 befinden sich außerdem Erweiterungsbohrungen 10, in denen Scheiben 5 angeordnet sind. Durch die Scheiben 5 und die Paßbiegebuchsen 4 geführte Dehnschrauben 6 verspannen zusammen mit Muttern 7 die Schwungradnaben 8 mit dem Wellenbund 3.In the figure, 1 denotes two halves of the flywheel, the are arranged on a shaft 2 and thereby with their flywheel hubs 8 on one Shaft collar 3 make contact. Through fitting holes 9 in the flywheel hubs 8 and in the shaft collar 3 fitting bend bushes 4 are guided. In the flywheel hubs 8 are also Expansion bores 10 in which disks 5 are arranged. Through the panes 5 and the fitting bend bushes 4 guided expansion screws 6 brace together with nuts 7 the flywheel hubs 8 with the shaft collar 3.

Durch den von den Dehnschrauben 6 erzeugten Reibschluß sind die Paßbiegebuchsen 4 vom Drehmoment entlastet, wobei sie aber gleichzeitig eine zusätzliche Sicherheit gegen Verdrehung bieten. Das Spiel zwischen Paßbiegebuchsen 4 und den Dehnschrauben 6 sowie den Scheiben 5 ermöglicht die Aufweitung des Innendurchmessers der Schwungradnaben 8 infolge der Fliehkräfte.Due to the frictional engagement generated by the expansion screws 6, the fitted bending bushes are 4 relieved of torque, but at the same time it is an additional safety offer against twisting. The play between the fitting bend bushes 4 and the expansion screws 6 and the disks 5 allow the internal diameter of the flywheel hubs to be expanded 8 due to centrifugal forces.

Die Paßbiegebuchsen 4 können durch elastische Biegung der Aufweitung der Schwungradnaben 8 folgen.The fitting bend bushings 4 can by elastic bending of the widening follow the flywheel hubs 8.
