Abstract

In the bearing arrangment for a motor shaft (7) of a pump drive, bearings (6, 11) are each arranged in a bearing holder (4, 11) made of elastic material. These bearing holders (4, 11) can have either a sealing lip (12) which provides a seal in the direction of the motor shaft (7) or an end wall (8) which closes off the motor housing (1) from the outside. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Lagerung der Motor­ welle eines Pumpenantriebs mittels zweier Lager, bei welcher jedes Lager mittels eines Lagerhalters in einem Gehäuse gehalten ist. Solche Lagerungen sind allgemein bekannt.The invention relates to a mounting of the engine shaft of a pump drive by means of two bearings, at which each bearing by means of a bearing holder in one Housing is held. Such bearings are general known.

Bei den bekannten Lagerungen ist der Lagerhalter als Klemmbrille ausgebildet und stellt ein relativ starres Bauteil dar. Deshalb werden Schwingungen der Motorwelle über den Lagerhalter auf das Motorgehäuse übertragen. Solche Schwingungen treten vor allem bei Pumpenantrieben unangenehm in Erscheinung, führen zu einem unerwünscht hohen Verschleiß und sind Ursache für störende Ge­ räusche.In the known bearings, the warehouse keeper is as Clamping glasses are designed and provide a relatively rigid Component. Therefore vibrations of the motor shaft Transfer to the motor housing via the bearing bracket. Such vibrations occur especially in pump drives unpleasant in appearance, lead to an undesirable high wear and are the cause of troublesome Ge noise.

Der Erfindung liegt die Aufgabe zugrunde, eine Lagerung der eingangs genannten Art derart zu gestalten, daß mit ihr Schwingungen der Motorwelle gedämpft werden können. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lagerhalter als außenseitig im Gehäuse gelagerte, elastische Ringkörper ausgebildet sind, welche innensei­ tig jeweils das Lager tragen.The invention has for its object a storage of the type mentioned in such a way that with her vibrations of the motor shaft can be damped.  This object is achieved in that the bearing brackets are mounted on the outside in the housing, elastic ring body are formed, which innensei always carry the bearing.

Durch diese Gestaltung wird die Motorwelle auf einfache Weise elastisch gelagert, so daß sie keine oder nur geringe Schwingungen auf das Motorgehäuse überträgt. Trotz dieser funktionellen Vorteile können die Lager­ halter überaus einfach gestaltet sein, so daß die Lage­ rung kostengünstig herstellbar ist, was insbesondere für Massenteile, um die es sich bei Pumpen meist handelt, bedeutsam ist.This design makes the motor shaft simple Way elastically mounted so that they have no or only transmits low vibrations to the motor housing. Despite these functional advantages, the bearings can holder be designed very simple, so that the location tion is inexpensive to manufacture, which is particularly important for Parts by mass, which are usually pumps, is significant.

Ganz besonders kostengünstig ist die Lagerung herstell­ bar, wenn die Lagerhalter im Gehäuse eingeknöpft sind. Durch dieses Merkmal ist eine rasche Montage möglich.The storage is particularly inexpensive to manufacture bar when the bearing brackets are buttoned into the housing. This feature enables quick assembly.

Die Lagerhalter vermögen eine Doppelfunktion auszuüben, wenn gemäß einer vorteilhaften Ausgestaltung der Erfin­ dung der pumpenseitige Lagerhalter eine auf der Motor­ welle aufliegende, umlaufende Dichtlippe hat. Der Lager­ halter ist dann zugleich eine Dichtung, so daß ein Bau­ teil eingespart wird. Weiterhin wird durch dieses Merk­ mal Bauraum eingespart und sichergestellt, daß die Dich­ tung genau mit dem Lager und damit der Motorwelle fluch­ tet.The warehouse keepers have a dual function, if according to an advantageous embodiment of the Erfin the pump-side bearing holder one on the motor shaft has circumferential sealing lip. The camp holder is then also a seal, so that a building part is saved. Furthermore, this note times saved space and ensured that you with the bearing and therefore the motor shaft tet.

Auch an der der Pumpenkammer gegenüberliegenden Seite kann der Lagerhalter zugleich die erforderliche Dicht­ funktion übernehmen, wenn der kollektorseitige Lager­ halter eine den Ringkörper außenseitig verschließende Stirnwand hat. Also on the side opposite the pump chamber the warehouse keeper can also provide the required seal take over function when the collector-side bearing holder that closes the outside of the ring body Front wall.  

Das jeweilige Lager ist rasch im Lagerhalter zu montie­ ren, wenn es jeweils in eine umlaufende Ringnut des Ringkörpers eingesetzt ist.The respective bearing can be installed quickly in the bearing holder ren, if it is in a circumferential annular groove of the Ring body is used.

Besonders kostengünstig und insbesondere für Kleinst­ pumpen vorteilhaft ist es, wenn das Lager jeweils ein geschlossener Ring aus Sintermaterial ist.Particularly inexpensive and especially for the smallest It is advantageous if the bearing is one each closed ring made of sintered material.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zu ihrer weiteren Verdeutlichung ist in der Zeichnung ein Pumpenmotor dargestellt, bei dem die beiden Lagerungen seiner Motorwelle im Längsschnitt wiedergegeben wurden.The invention allows numerous embodiments. To their further clarification is in the drawing Pump motor shown in which the two bearings its motor shaft were reproduced in longitudinal section.

Die Zeichnung zeigt ein zylindrisches Motorgehäuse 1, welches nach beiden Seiten hin jeweils von einer Stirn­ platte 2, 3 abgeschlossen ist. In die Stirnplatte 2 ist ein aus elastischem Material, insbesondere Gummi oder thermoplastischem Kautschuk, bestehender Lagerhalter 4 eingeknöpft, der in einer innenseitigen, umlaufenden Ringnut 5 ein Lager 6 haltert, bei dem es sich um einen Lagerring aus Sintermaterial handelt. Dieses Lager 6 lagert das kollektorseitige Ende einer Motorwelle 7.The drawing shows a cylindrical motor housing 1 , which is completed on both sides by an end plate 2 , 3 . A bearing holder 4 made of elastic material, in particular rubber or thermoplastic rubber, is buttoned into the end plate 2 and holds a bearing 6 in an inner circumferential annular groove 5 , which is a bearing ring made of sintered material. This bearing 6 supports the end of a motor shaft 7 on the collector side.

Bei dem Lagerhalter 6 handelt es sich um einen Ringkör­ per, der mit einer außenseitigen Stirnwand 8 eine Ein­ heit bildet, so daß der Lagerhalter 4 mit dieser Stirn­ wand 8 eine Öffnung 9 in der Stirnplatte 2 völlig ab­ schließt.The bearing holder 6 is a ring body, which forms a unit with an outside end wall 8 , so that the bearing holder 4 with this end wall 8 closes an opening 9 in the end plate 2 completely.

Auch in die Stirnplatte 3 ist ein Lagerhalter 10 mit einem Lager 11 eingeknöpft. Dieser Lagerhalter 10 unter­ scheidet sich von dem zuvor beschriebenen dadurch, daß er statt der Stirnwand 8 eine umlaufende Dichtlippe 12 hat, die dichtend auf der Motorwelle 7 aufliegt und dadurch einen auf dieser Seite befindlichen Pumpenraum 13 zum Motorgehäuse 1 hin abdichtet.A bearing holder 10 with a bearing 11 is also buttoned into the end plate 3 . This bearing holder 10 differs from the one described above in that instead of the end wall 8 it has a circumferential sealing lip 12 which rests sealingly on the motor shaft 7 and thereby seals a pump chamber 13 on this side to the motor housing 1 .
