Description
Die Erfindung geht aus von einer Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1. Eine solche Handwerkzeugmaschine ist aus
Es sind Exzenterschleifmaschinen bekannt, die einen in einem Gehäuse angeordneten Elektromotor mit einer in Richtung eines Schleiftellers weisenden Ankerwelle aufweisen. Die Ankerwelle ist auf der dem Schleifteller zugewandten Seite über ein Ankerkugellager im Gehäuse der Exzenterschleifmaschine abgestützt.Eccentric grinding machines are known which have an electric motor arranged in a housing with an armature shaft pointing in the direction of a grinding disc. The armature shaft is supported on the side facing the sanding pad via an anchor ball bearing in the housing of the eccentric sanding machine.
An ihrem dem Schleifteller zugewandten Ende ist die Ankerwelle in einen Lagersitz einer Exzenterhülse eingepreßt und ist mit dieser drehfest verbunden. Auf der dem Schleifteller zugewandten Seite der Exzenterhülse ist auf der Exzenterhülse ein Schleiftellerkugellager befestigt, über das der Schleifteller auf der Exzenterhülse gelagert ist. Ferner ist auf der Exzenterhülse im Bereich des Lagersitzes der Ankerwelle ein Lüfterrad eines Lüfters befestigt.At its end facing the sanding pad, the armature shaft is pressed into a bearing seat of an eccentric sleeve and is rotatably connected thereto. On the side facing the sanding pad of the eccentric sleeve, a sanding ball bearing is mounted on the eccentric sleeve, via which the sanding pad is mounted on the eccentric sleeve. Further, a fan of a fan is mounted on the eccentric sleeve in the region of the bearing seat of the armature shaft.
Die Erfindung geht aus von einer Handwerkzeugmaschine, die einen in einem Gehäuse angeordneten Motor mit einer Motorwelle aufweist, die über ein auf einer einem Schleifteller zugewandten Seite angeordnetes Wellenlager gelagert ist und die in einem Lagersitz mit einer Exzenterhülse drehfest verbunden ist, wobei die Exzenterhülse in axialer Richtung zumindest teilweise in das Wellenlager ragt und der axiale Bauraum des Wellenlagers zumindest teilweise, vorteilhaft vollständig, zur Antriebsverbindung der Exzenterhülse genutzt ist. Es kann axialer Bauraum eingespart und damit ein vorteilhaft tiefer Schwerpunkt und eine besonders handliche Handwerkzeugmaschine erreicht werden. Besonders vorteilhaft wirkt sich dies bei Handwerkzeugmaschinen aus, die einhändig über einen am Gehäuse angeformten Griff geführt werden.The invention relates to a power tool having a motor arranged in a housing with a motor shaft which is mounted on a arranged on a sanding pad side shaft bearing and which is rotatably connected in a bearing seat with an eccentric sleeve, wherein the eccentric sleeve in the axial Direction at least partially protrudes into the shaft bearing and the axial space of the shaft bearing is at least partially, advantageously completely, used for driving connection of the eccentric sleeve. It can be saved axial space and thus an advantageous low center of gravity and a particularly handy hand tool can be achieved. This has a particularly advantageous effect on hand-held power tools, which are guided with one hand by means of a grip formed on the housing.
Die Lösung kann bei verschiedenen, dem Fachmann als sinnvoll erscheinenden Antriebssystemen angewendet werden, wie beispielsweise bei pneumatisch angetriebenen Handwerkzeugmaschinen usw. Besonders vorteilhaft wird die erfindungsgemäße Lösung jedoch bei elektrisch angetriebenen Handwerkzeugmaschinen mit einem Elektromotor eingesetzt. Elektromotore sind in der Regel größer und schwerer als pneumatische Motore, wodurch sich bei elektrisch angetriebenen Handwerkzeugmaschinen die Einsparung von axialem Bauraum und der erreichbare tiefe Schwerpunkt besonders vorteilhaft auswirkt.The solution can be applied to various propulsion systems which appear meaningful to a person skilled in the art, such as, for example, pneumatically driven hand tool machines, etc. However, the solution according to the invention is used particularly advantageously with electrically driven hand tool machines having an electric motor. Electric motors are usually larger and heavier than pneumatic motors, which has a particularly advantageous effect on electrically powered hand tool machines, the saving of axial space and the achievable low center of gravity.
Ferner kann durch die Lösung ein kleiner Abstand zwischen dem Wellenlager und einem mit der Exzenterhülse verbundenen Schleiftellerlager erreicht werden, und zwar vorteilhaft ein Abstand zwischen 5 mm und 15 mm. Durch den kleinen Abstand ist ein günstiger Kräfteverlauf erzielbar, und Vibrationen können vermieden werden. Das Schleiftellerlager kann in der Exzenterhülse oder vorteilhaft auf der Exzenterhülse angeordnet sein.Furthermore, a small distance between the shaft bearing and a sanding disc bearing connected to the eccentric sleeve can be achieved by the solution, advantageously a distance between 5 mm and 15 mm. Due to the small distance a favorable flow of forces can be achieved, and vibrations can be avoided. The sanding pad bearing can be arranged in the eccentric sleeve or advantageously on the eccentric sleeve.
Durch die Handwekzeugmaschine gemäß Anspruch 1, kann eine einfache Montage der Handwerkzeugmaschine erreicht werden. Das Wellenlager und der Flansch können vormontiert und im vormontierten Zustand mit dem Gehäuseteil verbunden werden. Grundsätzlich ist jedoch auch denkbar, daß das Wellenlager direkt im Gehäuse der Handwerkzeugmaschine bzw. in einem den Motor tragenden Gehäuseteil gelagert ist.By hand tool according to claim 1, a simple assembly of the power tool can be achieved. The shaft bearing and the flange can be preassembled and connected in the preassembled state with the housing part. In principle, however, it is also conceivable that the shaft bearing is mounted directly in the housing of the power tool or in a motor-supporting housing part.
Der Flansch kann im Gehäuseteil über verschiedene, dem Fachmann als sinnvoll erscheinende formschlüssige, kraftschlüssige und/oder stoffschlüssige Verbindungen befestigt sein, beispielsweise über eine Klebeverbindung, Schraubverbindung, -Rastverbindung usw. Ist der Flansch jedoch über eine Preßverbindung im Gehäuseteil befestigt, kann eine einfache und schnelle Montage erreicht und zusätzliche Befestigungsteile können eingespart werden.The flange can be secured in the housing part via various, the skilled person appears useful form-fitting, non-positive and / or material connections, for example via an adhesive connection, screw, latching connection etc. However, the flange is attached via a press connection in the housing part, a simple and Fast assembly can be achieved and additional hardware can be saved.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß der Flansch auf der dem Schleifteller abgewandten Seite des Wellenlagers im Gehäuseteil befestigt ist, wodurch eine vorteilhafte Bauraumausnutzung erzielt werden kann.In a further embodiment of the invention, it is proposed that the flange is fastened on the side facing away from the sanding pad of the shaft bearing in the housing part, whereby an advantageous space utilization can be achieved.
Ferner wird vorgeschlagen, daß die Exzenterhülse einstückig mit einem Lüfterrad ausgeführt ist. Zusätzliche Bauteile, Montageaufwand, Bauraum und Kosten können eingespart werden. Möglich ist jedoch auch, ein separates Lüfterrad auf der Exzenterhülse zu befestigen, beispielsweise aufzupressen.It is also proposed that the eccentric sleeve is designed in one piece with a fan. Additional components, assembly costs, installation space and costs can be saved. However, it is also possible to attach a separate fan wheel on the eccentric sleeve, for example, to press.
Die erfindungsgemäße Lösung kann bei sämtlichen, dem Fachmann als sinnvoll erscheinenden Handwerkzeugmaschinen eingesetzt werden, wie insbesondere bei Exzenterschleifmaschinen, Schwingschleifmaschinen, Multischleifmaschinen usw.The solution according to the invention can be used in all hand-held power tools that appear appropriate to the person skilled in the art, in particular in eccentric grinding machines, vibratory grinding machines, multi-grinding machines, etc.
