Abstract

The invention concerns a vibration and sound absorber for reducing the dynamic and sound effects in mechanical assemblies to which it is secured by snap rings and rigid rings, screws or rivets or by adhesion. The absorber is characterized in that it is formed from bonded layers, namely of more than one layer of a viscoplastic compound (4), a layer of expanded sheet metal (2) and at least one further layer of conventional sheet metal (3) or expanded sheet metal (2). The individual metal sheets are separated from one another by a layer of the viscoplastic compound (4) and the outer surfaces of the absorber (1) are formed either by a layer of the viscoplastic compound (4) or a metal sheet (2, 3). The expanded metal sheet (2) in the absorber (1) can be replaced by a metal grid (20).

Description

Schwingungs- und SchalldämpferVibration and silencers
Gebiet der TechnikTechnical field
Diese technische Lösung betrifft die Bauart und die Zusammensetzung eines Schwingungs- und Schalldämpfers zur Herabsetzung der dynamischen und Schallwirkungen in Maschinenbaugruppen die eine bestimmte Schwingungsenergie bilden, wie zum Beispiel bei Rädern der Schienenfahrzeugen, Bremsscheiben, Lagern usw.This technical solution relates to the design and composition of a vibration and silencer to reduce the dynamic and sound effects in machine assemblies that form a certain vibration energy, such as wheels of rail vehicles, brake discs, bearings, etc.
Stand der TechnikState of the art
In sich bewegenden Maschinenbaugruppen entstehen Schwingun¬ gen der Bauteile die übertragen weden und Wellenbewegung bilden. Jedes schwingende System bildet eine bestimmte Gesamtenergie der Schwingungen, wobei je höher diese Energie ist, desto höher sind die dynamischen Auswirkungen des Systems, die folgend außer anderem auch Geräusche verschie¬ dener Frequenzen, die als Schall genannt sind,bilden.In moving machine assemblies, vibrations of the components occur which are transmitted and form wave motion. Each vibrating system forms a certain total energy of the vibrations, the higher this energy, the higher the dynamic effects of the system, which subsequently also form noises of different frequencies, which are called sound.
Zur Herabsetzung der Gesamtenergie der Schwingungen werden Dämpfer benutzt, was die mit der Hauptquelle der Schwingun¬ gen durch Steifringe, Schrauben, Nieten oder Aufkleben ver¬ bünde Körper sind.Dampers are used to reduce the total energy of the vibrations, which are the bodies which are connected to the main source of the vibrations by stiffening rings, screws, rivets or gluing.
Die bisher angewendeten Schwingungs- und Schalldämpfer sind durch ein übliches oder ein mit schwingungsdä ender Beschichtung versehenes Blech gebildet. Andere Dämpfer werden als Bleche mit Gummischichten in der Mitte oder als absorbierene Segmente aus Metallamellen und Plastmassen gebaut. Zur Erhöhung der Dämungswirkung werden manchmal im Blech auch Formschnitte durchgeführt. Ein Nachteil dieser Dämpfer ist, daß sie Dämmung im ganzen Frequenzband der Schwingungen nicht gewährleisten und daß die Dämmung lange dauert. Herstellung dieser Dämpfer ist meistens aufwendig und die Kosten sind manchmal nicht im Einklang mit den erreichten Resultaten. Das bedeutet, daß die dynamischen Wirkungen des Systems nur unbefriedigend beseitigt werden, was die Lebensdauer der Bauteile verkürzt. Im Falle der Gummianwendung kommen auch die Gummialterung und dadurch auch der Verlust der Elastizität vor.The previously used vibration and silencers are formed by a conventional or a coating provided with schwingungsdä ender coating. Other dampers are built as sheets with rubber layers in the middle or as absorbing segments made of metal plates and plastic materials. To increase the insulation effect, shape cuts are sometimes made in the sheet. A disadvantage of these dampers is that they do not ensure insulation in the entire frequency band of the vibrations and that the insulation takes a long time. The production of these dampers is usually complex and the costs are sometimes not in line with the results achieved. This means that the dynamic effects of the system are only unsatisfactorily eliminated, which shortens the life of the components. In the case of rubber application, there is also rubber aging and thus loss of elasticity.
Wesen der ErfindungEssence of the invention
Die oben erwähnten Mängel werden im beträchtlichen Maße durch einen Schwingungs- und Schalldämpfer beseitigt, der im wesentlichen darin besteht, daß er aus gemeinsam verbundenen Schichten gebildet ist, und zwar aus mehr als einer Schicht der viskos-plastischen Masse, aus einer Schicht des Streck¬ metallblechs, mindestens aus einer weiteren Schicht des üblichen Blechs oder des Streckmetallblechs. Die einzelnen Metallschichten sind voneinender durch eine Schicht der viskos-plastischen Masse getrennt und die äußeren Flächen des Schwingungs- und Schalldämpfers sind entweder durch eine Schicht der viskos-plastischen Masse oder eines Blechs gebildet oder jede Schicht des Streckmetallblechs im Schwin¬ gungs- und Schalldämpfer durch ein Metallnetz ersetzt werden kann.The above-mentioned shortcomings are eliminated to a considerable extent by a vibration and silencer, which essentially consists in that it is formed from layers which are joined together, namely from more than one layer of the viscous-plastic mass, from one layer of the stretch metal sheet, at least from a further layer of the usual sheet metal or expanded metal sheet. The individual metal layers are separated from one another by a layer of the viscous-plastic mass and the outer surfaces of the vibration and silencer are either formed by a layer of the viscous-plastic mass or a sheet or each layer of the expanded metal sheet in the vibration and silencer a metal mesh can be replaced.
Die einzelnen Metallschichten sind oberflächlich gegen Korrosion geschützt oder direkt aus korrosionsbeständigem Material hergestellt. Der eigene Dämpfer kann die Form einer runden Platte, einer Kreisringfläche, eines Bandes oder beliebige andere Form, die der Form des schwingendes Körpers entspricht, haben. Zu dem Teil der Baugruppe, der die größte Amplitude der Schwingungen hat, ist der Dämpfer durch die Sicherungs- und Steifringe, Schrauben, Nieten oder durch das Aufkleben befestigt.The individual metal layers are protected against corrosion on the surface or made directly from corrosion-resistant material. Your own damper can take the form of a round plate, an annular surface, a band or any other shape that corresponds to the shape of the vibrating body. To the part of the assembly that the has the greatest amplitude of the vibrations, the damper is secured by the circlips and stiffening rings, screws, rivets or by gluing.
Ein Vorteil dieses Schwingungs- und Schalldämpfers besteht darin, daß er die Schwingungen in einem breiten Frequenzband dämpft und daß die Dämpfung der Schwingungen in einem kurzen Zeitabschnitt vorkommt, was die gesamte Energie der Schwin¬ gungen in der Maschinenbaugruppe wesentlich herabsetzt. Es wird sich durch niedrigere Amplituden der Schwingungen, Herabsetzung der dynamischen Wirkungen, erhöhte Lebensdauer der Bauteile und Herabsetzung des Schallpegels erweisen. Ein weiterer Vorteil des Dämpfers ist, daß seine Form und Befestigung an die Form des schwingenden Teils angepasst werden kann und daß er nachträglich auch in die schon angewendete Maschinenbaugruppen eingebaut werden kann.An advantage of this vibration and sound damper is that it dampens the vibrations in a wide frequency band and that the damping of the vibrations occurs in a short period of time, which substantially reduces the total energy of the vibrations in the machine assembly. It will prove to be due to lower vibrations amplitudes, reduced dynamic effects, increased component life and reduced sound levels. Another advantage of the damper is that its shape and attachment can be adapted to the shape of the vibrating part and that it can also be retrofitted into the machine assemblies already in use.
