Description

S p a n n e i n r i c h t u n g f ü r S c h l e i f s c h e i b e n S p a n e i n r i c h t u n g for S c h l e i f s c h e i b e n

Die Erfindung bezieht sich auf eine Spanneinrichtung für Schleifscheiben mit Spannelementen, die von zwei Spannflanschen oder einem Spannflansch und einer Spann- mutter gebildet werden und gegebenenfalls einer.Dämpfungseinlage.The invention relates to a clamping device for grinding wheels with clamping elements which are formed by two clamping flanges or a clamping flange and a clamping nut and, if appropriate, a damping insert.

Es ist bekannt, daß die Geräuschentwicklung beim Schleifen, insbesondere beim Schleifen mittels handgeführter Maschinen wesentlich zu der hohen Lärmbelastung beiträgt, die an vielen Arbeitsplätzen besteht. Insbesondere trifft dies bei der Metall- Verarbeitung zu.It is known that the noise development during grinding, especially when grinding by means of hand-held machines, contributes significantly to the high noise pollution that exists at many workplaces. This applies in particular to metal processing.

Um die Lärmentwicklung beim Schleifen zu vermindern, wurden bereits geräuscharme Schleifscheiben entwickelt. Dies führte zwar durchaus zu einer Verminderung der Lärmbelastung, führte jedoch andererseits zu einem geringeren Abtrag der Schleif- Scheiben, wodurch der Arbeitsfortschritt und die Rentabilität der Schleifscheiben wesentlich herabgesetzt wurden.Low-noise grinding wheels have already been developed to reduce noise during grinding. Although this did lead to a reduction in noise pollution, on the other hand it led to less abrasion of the grinding wheels, which significantly reduced the work progress and the profitability of the grinding wheels.

Die DE 43 28 987 C1 zeigt den Einbau separater elastischer Einlagen in Spannsysteme mit dem Ziel, einen Spannungs- bzw. Maßausgleich zu ermöglichen.DE 43 28 987 C1 shows the installation of separate elastic inserts in tensioning systems with the aim of enabling tension or dimension compensation.

Aus der DE 195 12 991 ist eine Einspannvorrichtung für den Einsatz in einem Drehwerkzeug bekannt, mit der Schwingungen eines Werkzeugelementes absorbiert werden sollen. Gleichzeitig soll die Haltbarkeit verbessert werden. Die in der genannten Schrift gezeigte Lösung hat den Nachteil, daß durch die scheibenförmige Ausführung der elastischen Einlage Schwingungen in radialer Richtung nicht gedämpft werden können.From DE 195 12 991 a clamping device for use in a turning tool is known, with which vibrations of a tool element are to be absorbed. At the same time, the durability should be improved. The solution shown in the cited document has the disadvantage that vibrations in the radial direction cannot be damped by the disk-shaped design of the elastic insert.

Aufgabe der Erfindung ist es, eine Spanneinrichtung der eingangs erwähnten Art dahingehend zu verbessern, daß beim Einsatz einer herkömmlichen Schleifscheibe ohne besondere Dämpfung eine Herabsetzung der Lärmentwicklung erreicht wird.The object of the invention is to improve a tensioning device of the type mentioned at the outset such that a reduction in noise is achieved when using a conventional grinding wheel without special damping.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß zwischen mindestens einem Spannelement und der Schleifscheibe ein steifer, vorzugsweise metallischer Zwischenring angeordnet ist, der die Schleifscheibe vom Spanneiement distanziert und daß der Zwischenring oder das dem Zwischenring benachbarte Spannelement mit einer fixierten Dämpfungsschichte aus elastischem Material versehen ist, die sich sowohl in radialer als auch axialer Richtung erstreckt.The object of the invention is achieved in that a stiff, preferably metallic intermediate ring is arranged between at least one clamping element and the grinding wheel, which spacers the grinding wheel from the clamping element and that The intermediate ring or the clamping element adjacent to the intermediate ring is provided with a fixed damping layer made of elastic material, which extends both in the radial and in the axial direction.

Vorteilhaft ist vorgesehen, daß das Spannelement, die Dämpfungsschichte und der Zwischenring miteinander zu einem Stück verbunden, beispielsweise miteinander verklebt sind.It is advantageously provided that the tensioning element, the damping layer and the intermediate ring are connected to one another, for example glued to one another.

Ein weiterer Vorteil der Erfindung ist, daß sich die Dämpfungsschichte sowohl in ra- dialer als auch axialer Richtung erstreckt und bei verringerter Lärm- und Vibrationsbelastung eine erhöhte Lebensdauer der Schleifscheibe erreicht wird.Another advantage of the invention is that the damping layer extends both in the radial and in the axial direction and an increased service life of the grinding wheel is achieved with reduced noise and vibration loads.

Nachfolgend werden verschiedene Ausführungsbeispiele der Erfindung anhand der Figuren der beiliegenden Zeichnungen beschrieben.Various exemplary embodiments of the invention are described below with reference to the figures of the accompanying drawings.

Die Fig. 1 bis 4 zeigen Schnitte durch verschiedene Ausführungsbeispiele einer erfindungsgemäßen Spanneinrichtung, in der jeweils eine Schleifscheibe eingespannt ist, und die Fig. 5 zeigt einen Schnitt durch eine erfindungsgemäße Spanneinrichtung, wobei die Teile der Spanneinrichtung auseinandergezogen gezeichnet sind.1 to 4 show sections through different exemplary embodiments of a clamping device according to the invention, in each of which a grinding wheel is clamped, and FIG. 5 shows a section through a clamping device according to the invention, the parts of the clamping device being drawn apart.

Die erfindungsgemäße Spanneinrichtung besteht aus zwei Spannelementen, wobei in den gezeigten Ausführungsbeispielen eines der Spannelemente von einem Spannflansch 1 und das zweite Spannelement von einer Spannmutter 2 gebildet wird. Die Erfindung kann jedoch ebenfalls bei einer Spanneinrichtung mit zwei Spannflanschen zur Anwendung kommen.The clamping device according to the invention consists of two clamping elements, one of the clamping elements being formed by a clamping flange 1 and the second clamping element being formed by a clamping nut 2 in the exemplary embodiments shown. However, the invention can also be used in a clamping device with two clamping flanges.

Erfindungsgemäß ist der Spannflansch 1 mit einer Dämpfungsschichte 9 versehen. In den gezeigten Ausführungsbeispielen ist weiters zwischen dem Spannflansch 1 und der Schleifscheibe 3, 4 ein Zwischenring 5 angeordnet, der vorzugsweise aus dem gleichen Material wie der Spannflansch 1 und die Spannmutter 2, beispielsweise einem Stahlguß oder Stahlblech, gefertigt ist. Im Ausfuhrungsbeispiel nach der Fig 1 ist in der Spanneinrichtung eine SchleifscheibeAccording to the clamping flange 1 is provided with a damping layer 9. In the exemplary embodiments shown, an intermediate ring 5 is further arranged between the clamping flange 1 and the grinding wheel 3, 4, which is preferably made of the same material as the clamping flange 1 and the clamping nut 2, for example a cast steel or sheet steel. In the exemplary embodiment according to FIG. 1, a grinding wheel is in the clamping device

3 gespannt, die als gekröpfte Schruppschleifscheibe mit einer ringförmigen Grob- schleifschichte 6 ausgebildet ist3 stretched, which is designed as a cranked rough grinding wheel with an annular rough grinding layer 6

Der Zwischenring 5 weist einen zur Spannmutter 2 weisenden Vorsprung 7 auf, der in die Nabenoffnung 8 der Schleifscheibe 3 ragt und der im Ausfuhrungsbeispiel innen an der Schleifscheibe 3 anliegtThe intermediate ring 5 has a projection 7 pointing towards the clamping nut 2, which protrudes into the hub opening 8 of the grinding wheel 3 and which in the exemplary embodiment rests on the inside of the grinding wheel 3

Zwischen dem Zwischenring 5 und dem Spannflansch 1 befindet sich eine Dam- pfungsschichte 9 aus einem elastomeren Material Die Dampfungsschichte 9 ist ebenso wie der Zwischenring 5 ringförmig ausgebildet und weist einen scheibenförmigen Bereich 10 und einen hulsenformigen Bereich 11 aufBetween the intermediate ring 5 and the clamping flange 1 there is a damping layer 9 made of an elastomeric material. Like the intermediate ring 5, the damping layer 9 is ring-shaped and has a disk-shaped area 10 and a sleeve-shaped area 11

Der Durchmesser der Nabenoffnung 8 der Schleifscheibe 3 betragt mehr als ein Viertel des Außendurchmessers da der Schleifscheibe 3The diameter of the hub opening 8 of the grinding wheel 3 is more than a quarter of the outer diameter since the grinding wheel 3

Durch dieses Großenverhaltnis ist die Schleifscheibe 3 beim Einsatz steifer Es tritt ein im Verhältnis zur gesamten Masse der Schleifscheibe 3 geringerer Abfall auf und der Anteil der Dampfungsmasse der Dampfungsschichte 9 kann im Verhältnis zur Masse der Schleifscheibe 3 erhöht werdenThis large ratio makes the grinding wheel 3 more rigid when used. There is less waste in relation to the total mass of the grinding wheel 3 and the proportion of the damping mass of the damping layer 9 can be increased in relation to the mass of the grinding wheel 3

Auf diese Art kann bei gleicher Zerspanungsleistung eine 50%ιge Lebensdauererho- hung der Schleifscheibe 3 erreicht werdenIn this way, a 50% increase in the service life of the grinding wheel 3 can be achieved with the same cutting performance

Im Ausfuhrungsbeispiel nach der Fig 2 ist die erfindungsgemaße Spanneinrichtung mit einer Schleifscheibe 4 versehen, die als Trennscheibe ausgebildet ist Die Spannein- richtung weist wiederum einen Spannfiansch 1 , eine Spannmutter 2 und einen Zwischenring 5 auf, wobei in diesem Ausfuhrungsbeispiel eine Dampfungsschichte 9 analog dem vorher beschriebenen Ausfuhrungsbeispiel vorgesehen ist und eine wei- tere ringförmige Dampfungsschichte 12, die sich zwischen der Schleifscheibe 4 und der Spannmutter 2 befindetIn the exemplary embodiment according to FIG. 2, the clamping device according to the invention is provided with a grinding wheel 4, which is designed as a cutting disc.

Die Dämpfungsschichte 14 zwischen dem Spannflansch 1 und dem Zwischenring 5 weist einen radialen Abschnitt 15, einen axialen Abschnitt 16, der zwischen dem hülsenförmigen Vorsprung 13 und dem Spannfiansch 1 angeordnet ist, und einen weiteren radialen Abschnitt 17, der den hülsenförmigen Vorsprung 13 des Zwischenringes 5 vom Spannflansch 1 trennt, auf. Zwischen dem hülsenförmigen Vorsprung 13 und dem hülsenförmigen Bereich der Spannmutter 2 ist im Spiel vorgesehen.5 protrudes. The damping layer 14 between the clamping flange 1 and the intermediate ring 5 has a radial section 15, an axial section 16 which is arranged between the sleeve-shaped projection 13 and the clamping flange 1, and a further radial section 17 which the sleeve-shaped projection 13 of the intermediate ring 5 separates from the clamping flange 1. Between the sleeve-shaped projection 13 and the sleeve-shaped area of the clamping nut 2 is provided in the game.

An der der Spannmutter 2 zugeordneten Seite ragt der hülsenförmige Vorsprung 13 in die Nabenöffnung 8 der Schleifscheibe 4.On the side assigned to the clamping nut 2, the sleeve-shaped projection 13 projects into the hub opening 8 of the grinding wheel 4.

Zwischen der Schleifscheibe 4 und der Spannmutter 2 ist wiederum eine Dämpfungsschichte 12 vorgesehen. Die Dämpfungsschichte 14 dient zugleich als Klebeschicht, sodaß die Teile 1 und 5 vom Benutzer als gemeinsames Teil gehandhabt werden können.A damping layer 12 is again provided between the grinding wheel 4 and the clamping nut 2. The damping layer 14 also serves as an adhesive layer, so that the parts 1 and 5 can be handled by the user as a common part.

Im Ausführungsbeispiel nach der Fig. 5 ist wiederum der Zwischenring 5 mit dem Spannfiansch 1 über eine Dämpfungsschichte 9, die auch als Klebeschichte ausgebil- det ist, verbunden.In the exemplary embodiment according to FIG. 5, the intermediate ring 5 is in turn connected to the clamping flange 1 via a damping layer 9, which is also designed as an adhesive layer.

Die Spannmutter 2 wird von einem Kernteil 18 und einem äußeren Ringteil 19 gebildet. Diese beiden Teile 18, 19 sind wiederum mittels einer Dämpfungsschichte 20, die beispielsweise von einem Butylkautschuk gebildet wird, verklebt.The clamping nut 2 is formed by a core part 18 and an outer ring part 19. These two parts 18, 19 are in turn glued by means of a damping layer 20, which is formed, for example, by a butyl rubber.

Die Spannmutter 2 ist in den gezeigten Ausführungsbeispielen in herkömmlicher Weise mit der Abtriebswelle einer Schleifmaschine, beispielsweise einer Handschleifmaschine verschraubt. In the exemplary embodiments shown, the clamping nut 2 is screwed in a conventional manner to the output shaft of a grinding machine, for example a hand-held grinding machine.
