Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a hand tool according to the preamble of claim 1.

Als nächstliegender Stand der Technik wird das Dokument GB 2 154 497 A betrachtet.The closest prior art is the document GB 2 154 497 A considered.

Aus der DE 40 00 861 C2 ist eine Handwerkzeugmaschine mit einem Motorgehäuse bekannt, das auf der einer Werkzeugaufnahme abgewandten Seite der Schlagbohrmaschine von einem Hüllgehäuse umgeben ist. An das Hüllgehäuse ist ein Handgriff mit einem Griffelement angeformt. Das Hüllgehäuse ist über eine Schwingungsdämpfungsvorrichtung mit dem Motorgehäuse verbunden, das gleichzeitig ein Trägerelement für den Handgriff bildet. Die Schwingungsdämpfungsvorrichtung weist mehrere elastische Schwingungsdämpfungseinheiten aus Gummi auf, über die das Hüllgehäuse, und damit das Griffelement, vom Motorgehäuse schwingungsmäßig entkoppelt ist.From the DE 40 00 861 C2 a hand tool machine with a motor housing is known, which is surrounded on the side facing away from a tool holder side of the percussion drill by an enclosure. At the casing a handle with a handle element is formed. The envelope housing is connected via a vibration damping device to the motor housing, which simultaneously forms a support element for the handle. The vibration damping device comprises a plurality of elastic vibration damping units made of rubber, over which the jacket, and thus the handle element, is decoupled from the motor housing in terms of vibration.

Eine derartige Handwerkzeugmaschine geht beispielweise auch aus der US 5 322 131 A und US 6 286 610 B1 hervor.Such a hand tool machine is, for example, from the US 5,322,131 A and US Pat. No. 6,286,610 B1 out.

Vorteile der ErfindungAdvantages of the invention

Die Erfindung geht aus von einer Handwerkzeugmaschine mit einem Gehäuse, in dem Antriebseinheiten angeordnet sind, wobei im Gehäuse zumindest eine Schwingungsdämpfungsvorrichtung vorgesehen ist.The invention relates to a hand tool with a housing in which drive units are arranged, wherein at least one vibration damping device is provided in the housing.

Es wird vorgeschlagen, dass eine Antriebsanordnung mit zumindest einer Antriebseinheit durch die Schwingungsdämpfungsvorrichtung gegenüber dem Gehäuse in axialer, radialer und Umfangsrichtung entkoppelt ist. Etwaige Gerätevibrationen können in allen drei Schwingungsrichtungen abgefangen werden. Zugleich besteht die Möglichkeit, einen Versatz von Mittelachsen von Antriebseinheiten in der Antriebsanordnung auszugleichen. Sowohl Wirkungsweise als auch Handhabung der Handwerkzeugmaschine bleiben unbeeinflusst.It is proposed that a drive arrangement with at least one drive unit is decoupled by the vibration damping device with respect to the housing in the axial, radial and circumferential directions. Any device vibrations can be intercepted in all three directions of vibration. At the same time it is possible to compensate for an offset of central axes of drive units in the drive assembly. Both mode of action and handling of the power tool remain unaffected.

Umfasst die Antriebsanordnung entlang einer Längserstreckung zumindest einen Antriebsmotor und/oder ein Getriebe und/oder eine Kupplung und/oder einen Werkzeugantrieb, können geeignete Schwingungsdämpfungseinheiten zur Dämpfung von für die verschiedenen Antriebseinheiten spezifischen Schwingungsrichtungen an unterschiedlichen Antriebseinheiten gezielt platziert werden. Vorteilhaft kann ein etwaiger Versatz von Mittelachsen der Antriebseinheiten, die in einer starren Antriebsanordnung zusammengefasst sind, kostengünstig ausgeglichen werden, da auf zusätzliche Ausgleichselemente oder eine aufwändige und teure Innenkontur im Gehäuse verzichtet werden kann.If the drive arrangement comprises at least one drive motor and / or a transmission and / or a clutch and / or a tool drive along a longitudinal extension, suitable vibration damping units can be selectively placed on different drive units for damping vibration directions specific to the various drive units. Advantageously, a possible offset of central axes of the drive units, which are combined in a rigid drive arrangement, be compensated cost-effectively, since it can be dispensed with additional compensation elements or a complex and expensive inner contour in the housing.

In einer bevorzugten Ausgestaltung weist die Handwerkzeugmaschine eine Schwingungsdämpfungsvorrichtung wie im Anspruch 1 angegeben.In a preferred embodiment, the handheld power tool has a vibration damping device as specified in claim 1.

Bildet die Antriebsanordnung eine im Wesentlichen starre Einheit, kann mit einer geeigneten Verteilung der Schwingungsdämpfungseinheiten der Schwingungsdämpfungsvorrichtung eine vorteilhafte Lagerung der Antriebsanordnung ausschließlich durch die Schwingungsdämpfungsvorrichtung realisiert werden. Die Antriebsanordnung kann dadurch praktisch vollständig von dem Gehäuse entkoppelt werden. Vorzugsweise liegt die Antriebsanordnung nur über die Schwingungsdämpfungsvorrichtung an dem Gehäuse an. Eine gute Handhabung und Wirkungsweise der Handwerkzeugmaschine bleibt erhalten.If the drive arrangement forms a substantially rigid unit, with a suitable distribution of the vibration damping units of the vibration damping device, an advantageous mounting of the drive arrangement can be realized exclusively by the vibration damping device. The drive assembly can thereby be decoupled practically completely from the housing. Preferably, the drive assembly rests against the housing only via the vibration damping device. Good handling and operation of the power tool is maintained.

Die erfindungsgemäße Lösung kann bei verschiedenen, dem Fachmann als sinnvoll erscheinenden Werkzeugmaschinen angewendet werden, jedoch besonders vorteilhaft bei elektrisch angetriebenen Handwerkzeugmaschinen, wie beispielsweise Schlagbohrmaschinen, Schabern, Sägen, Schraubern und insbesondere Winkelschleifern usw., die aufgrund ihrer meist freien Beweglichkeit und häufig hohen Antriebsdrehzahlen grundsätzlich zu Schwingungen neigen. Sehr günstig ist der Einsatz bei solchen Handwerkzeugmaschinen, bei denen kein zusätzlicher Handgriff oder keine zusätzlichen Haltemöglichkeiten außerhalb des Bereichs der umhüllenden Geometrie vorgesehen sind, sondern deren Gehäuse selbst einen Handgriff darstellt, wie beispielsweise bei handgeführten Schraubern, Industrieschraubern mit geregeltem Abschaltmoment und dergleichen.The solution according to the invention can be applied to various machine tools that appear appropriate to the person skilled in the art be, but particularly advantageous in electrically powered hand tool machines, such as impact drills, scrapers, saws, screwdrivers and in particular angle grinders, etc., which generally tend to vibrate due to their mostly free mobility and often high input speeds. Very low is the use of such hand tool machines, in which no additional handle or no additional holding options are provided outside the range of the enveloping geometry, but the housing itself is a handle, such as hand-held screwdrivers, industrial screwdrivers with controlled shutdown and the like.
