Abstract

The device has an attachment e.g. resonance body, provided between a noise producing component e.g. engine (1) and magnet, and housing (2), where the attachment consists of metallic spring shape. The noise producing component is provided to transfer vibrations and operating noise to the housing. A sounding board is provided in the device. A spring ring (3) from the noise producing component to the attachment is made of metal.

Description

Die Erfindung betrifft eine Vorrichtung zum Vermeiden von KörperschallübertragungenThe The invention relates to a device for avoiding structure-borne sound transmissions

Bekannt sind Vorrichtungen zum Vermeiden von Körperschall mittels gummiartigen weichen Teilen.Known are devices for the prevention of structure-borne sound by means of rubbery soft parts.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die die Körperschallübertragung auf ein Minimum reduziert.outgoing From this prior art, the invention is based on the object to provide a device of the type mentioned, which is the Borne sound transmission reduced to a minimum.

Geräuscherzeugende Bauelemente, z. B. Motoren oder Magneten müssen jeweils in ein Gehäuse eingebaut werden, dabei wird das Gehäuse zum Resonanzboden und verstärkt das Geräusch um ein Vielfaches (ca. 10–20 dBA). Die Erfindung beschreibt am Beispiel Kugellagerbefestigung eine Aufhängung deren Geometrie eine Verringerung der Körperschallintensität bis 15 dBA bewirkt.noise generators Components, eg. B. motors or magnets must each be installed in a housing be, while the case becomes Soundboard and amplified the noise around a multiple (about 10-20 dBA). The invention describes the example ball bearing attachment a suspension whose geometry reduces the structure-borne sound intensity up to 15 dBA causes.

Gepresster Gummi hat keine lärmdämpfende Eigenschaften. Gummiartige und weiche Aufhängungen sind in der Regel nicht geeignet, die notwendige Positionierung zwischen Motor und Gehäuse zu gewährleisten, wenn bei Einwirkung von Kraft, wie Drehmoment, Radial- oder Axialkraft auf das System einwirkt. Die Erfindung beschreibt eine Anordnung eines metallischen Federgeblides, das sehr hohe Kräfte aufnehmen kann, um kraftabgebende Teile gegenseitig zu fixieren und trotzdem eine körperschalldämfende Eigenschaft besitzt Die Erfindung wird nun anhand der Zeichnung beispielhaft beschrieben.pressed Rubber has no sound-absorbing Properties. Rubbery and soft suspensions are usually not suitable to ensure the necessary positioning between motor and housing, if under the action of force, such as torque, radial or axial force acting on the system. The invention describes an arrangement a metallic spring blender that absorb very high forces can fix each other in order to force-giving parts and still a structure-borne sound absorbing property The invention will now be described by way of example with reference to the drawing described.

Geräuscherzeugendes Bauelement 1 überträgt Vibrationen und Laufgeräusche auf das Gehäuse 2. Durch eine besondere Ausbildung eines Abstandshalters 3 wird verhindert, dass Vibrationen und Laufgeräusche vom Bauelement 1 zum Gehäuse 2 sehr stark gedämpft werden.Noise generating component 1 transmits vibrations and running noise to the housing 2 , By a special design of a spacer 3 will prevent vibration and running noise from the device 1 to the housing 2 be very much attenuated.
