Antriebseinrichtung, vorzugsweise Elektromotor für ümluftgebläse von BacköfenDrive device, preferably electric motor for air blower of ovens

Die Erfindung geht aus von einer Antriebseinrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention is based on a drive device according to the preamble of claim 1.

Bei Antriebseinrichtungen, insbesondere bei Umluftgebläsemotoren für Backöfen, die hohen Temperaturen ausgesetzt sind, besteht einerseits der Wunsch nach geräuscharmer Feinlagerung des Abtriebsteiles mit genauen Lagerpassungen, andererseits soll jedoch das starken Temperaturschwankungen ausgesetzte Lagermaterial sich ungehindert ausdehnen können, was wiederum für die Verwendung einer Groblagerung spricht. Aus den zuletzt genannten Gründen hat man.sich bei Vermeidung einer aufwendigen Wärmeisolierung in der Praxis meist für geräuschintensive Groblager entschieden.With drive devices, especially with circulating air fan motors For ovens that are exposed to high temperatures, there is on the one hand the desire for quieter ones Fine bearing of the output part with precise bearing fits, but on the other hand, there should be strong temperature fluctuations exposed storage material can expand unhindered, which in turn speaks for the use of a coarse storage. For the reasons mentioned last, one has to avoid expensive thermal insulation in practice decided for noisy coarse bearings.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebseinrichtung gemäß dem Oberbegriff des Patentanspruches 1 so auszugestalten, daß auf der einen Seite auf kostenintensirve, weitgehend spielfreie Peinlagerung und Passungsgenauigkeit verzichtet werden kann und auf der anderen Seite trotz-The invention is based on the object of a drive device to design according to the preamble of claim 1 so that on the one hand on cost-intensive, largely backlash-free positioning and accuracy of fit can be dispensed with and on the other hand despite-

dem eine hohe Geräuscharmut erhalten wird«,which is kept very quiet «,

Diese Aufgabe wird gelöst durch die im Kennzeichxramgsteil des Patentanspruches 1 aufgeführte Lehre zum technischen Handeln.This task is solved by the in the identification part of claim 1 listed teaching on technical action.

Durch die Lagerung des Drehlagers, z.B„ eines relativ groben Kugellagers in einem elastisch nachgiebigen, vorzugsweise aus geräuschdämmendem Material bestehenden Lagerelement, wird insbesondere erreicht, daß an die Passgenauigkeit des Lagersitzes im feststehenden Lagerkürper keinerlei Anforderungen mehr gestellt zu werden brauchen. Sämtliche Lagertoleranzen werden mit dem Einbringen des elastisch nachgiebigen Lageelementes in den Lagersitz voll ausgeglichen und es wird hierbei ein hohes Maß an Rundlaufgenauigkeit erzielt.Due to the storage of the pivot bearing, e.g. a relatively coarse one Ball bearing in an elastically flexible bearing element, preferably made of noise-absorbing material, is achieved in particular that the accuracy of fit of the bearing seat in the fixed bearing body No more requirements need to be made. All storage tolerances are reduced with the introduction of the elastically resilient position element in the bearing seat is fully balanced and there is a high degree of concentricity achieved.

Gemäß einer bevorzugten Ausführungsform sind das oder die Drehlager, vorzugsweise Kugellager, in elastischer Füllmasse eingebettet. Als Füllmasse kann ein besonders geräuschdämpfendes Material wie Silikonkautschuk, ein Gemisch aus Metallpulver und Kunststoffpulver oder dergleichen verwendet werden. Das Einbetten des Drehlagers kann nach vorherigem Zentrieren des Abtriebsteiles gegenüber dem Lagerkörper, z.B. in einem Spritzvorgang, maschinell erfolgen.According to a preferred embodiment, that or those Pivot bearings, preferably ball bearings, embedded in an elastic filling compound. A particularly noise-dampening compound can be used as the filling compound Material such as silicone rubber, a mixture of metal powder and plastic powder or the like is used will. The pivot bearing can be embedded after prior centering of the driven part relative to the bearing body, e.g. in one injection process, done by machine.

Dureh die Erfindung ergibt sich die Möglichkeit, für die Lagerung des Abtriebsteiles ein Groblager zu verwenden, das auch gegenüber extremen TemperaturSchwankungen unempfindlich ist. Trotzdem wird ein hohes Maß an Geräuscharmut durch das elastische Lagerelement oder Lagermaterial erzielt, das gleichzeitig geräuschdämpfend wirkt. Die Herstellung wird auf diese Weise wesentlich vereinfacht und die Kosten vermindert, indem der Lagerkörper z.B. als Spritzguß-Rohteil ohne weitere Feinbearbeitung ausgebildet sein kann.Through the invention there is the possibility for storage of the output part to use a coarse bearing that is also insensitive to extreme temperature fluctuations. Nevertheless, a high level of low noise is achieved by the elastic bearing element or bearing material, which at the same time has a noise-dampening effect. The production is considerably simplified in this way and the costs are reduced by the Bearing body, e.g. as an injection molded raw part without further fine processing can be formed.

Bei der Antriebseinrichtung gemäß den Figuren handelt es sich um einen sogenannten Innenläufer-Elektromotor, obwohl die Erfindung selbstverständlich auch bei einem Außenläufermotor anwendbar ist. Hierbei ist mit 1 die Abtriebswelle und mit 2 ein feststehender, in Form eines Gehäuses ausgebildeter Lagerkörper bezeichnet. Im Inneren des Lagerkörpers 2 ist auf der Abtriebswelle i im Bereich 3 eine nicht weiter dargestellte Rotorwicklung angeordnet, während im Bereich 4 des Lagerkörpers 2 die zugehörige Statorwicklung untergebracht sein kann. Mit 5 sind lameliierte Eotoreisen bezeichnet. Der Lagerkörper 2 ist an beiden axialen Enden mit jeweils einer Lageröffnung 6 bzw. 6* versehen. Die lichtenWeiten der Lageröffnung 6, 6* ist größer als der Durchmesser von Drehlager darstellenden Kugellagern 7, wodurch die Kugellager 7 mit radialem Spiel in die kreisrunden, und napfförmigen Lageröffnungen 6 bzw. 6' eingesetzt werden können. Beim AusfUhrungsbeispiel gemäß Fig.l ist der Hohlraum zwischen Kugellager 7 und Lagerkörper 2 ausgefüllt mit einer elastischen und elastisch bleibenden Füllmasse 8, z.B. Silikonkautschuk. Zur unverdrehbaren Halterung dieses Füllmassen-Formteils 8 sind im hülsenförmigen Lagerkörper 2 Bohrungen 9 eingearbeitet, die von der Füllmasse ausge-The drive device according to the figures is a so-called internal rotor electric motor, although the invention can of course also be used with an external rotor motor. Here, with the output shaft 1 and designated 2, a fixed, formed in the form of a housing bearing body. In the interior of the bearing body 2, a rotor winding (not shown ) is arranged on the output shaft i in the area 3 , while the associated stator winding can be accommodated in the area 4 of the bearing body 2. With 5 laminated Eotor trips are designated. The bearing body 2 is provided with a bearing opening 6 or 6 * at both axial ends. The clear widths of the bearing opening 6, 6 * is greater than the diameter of the ball bearings 7 representing pivot bearings, whereby the ball bearings 7 can be inserted into the circular and cup-shaped bearing openings 6 and 6 'with radial play. In the exemplary embodiment according to FIG. 1, the cavity between the ball bearing 7 and the bearing body 2 is filled with an elastic and elastic filling compound 8, for example silicone rubber. For the non-rotatable holding of this molding compound 8, 2 bores 9 are incorporated in the sleeve-shaped bearing body, which are formed by the filling compound.
