Abstract

The shaft end of the motor(3, 4) on the side of the brush is mounted in a slide bearing(6) held secure on the fan unit housing(1) by a positive connection(9, 10) in the peripheral direction and a snap fitting connection(11) int he axial direction. The fan housing(1) can have a peg(10) which engages in a bore(9) in the slide bearing housing(7) whilst a ratchet tongue(11) is mounted opposite this around the edge of the bearing opening. The slide bearing need only be inserted in the bearing opening in the fan housing(1) and then pressed in against the ratchet tongue which then snaps over the edge of the housing(7) of the slide bearing.

Description

Gebläseaggregat für einen StaubsaugerBlower unit for a vacuum cleaner

Die Erfindung bezieht sich auf ein Gebläseaggregat für einen Staubsauger, dessen Motor mit seinem bürstenseitigen Wellenende in einem Gleitlager gelagert ist, das über sein Gehäuse am Aggregategehäuse gehaltert ist.The invention relates to a blower unit for a vacuum cleaner, whose motor is mounted with its brush-side shaft end in a plain bearing is, which is held on its housing on the unit housing.

Bisher hat man das Gleitlager durch in Gewindebohrungen des Gleitlagergehäuses eingreifende Schrauben am Aggregategehäuse befestigt, wie dies in der Zeichnung der DE-OS 21 44 109 dargestellt ist.So far you have the plain bearing through in threaded holes in the plain bearing housing engaging screws attached to the unit housing, as shown in the drawing DE-OS 21 44 109 is shown.

Der Erfindung liegt die Aufgabe zugrunde, ein Gebläseaggregat zu schaffen, bei dem das Anbringen des Gleitlagers im Aggregategehäuse wesentlich vereinfacht ist, Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß das Gleitlager in Umfangsrichtung durch Formschluß und in axialer Richtung durch eine Schnappverbindung gehalten ist. Das Gleitlager braucht somit nur noch in die im Aggregategehäuse vorgesehene Lageröffnung eingelegt und gegen die Schnappverbindung in diese hineingedrückt werden. Ein solches Anbringen des Gleitlagers eignet sich insbesondere für eine automatische Fertigung.The invention is based on the object of creating a blower unit, in which the mounting of the plain bearing in the unit housing is significantly simplified is, The solution of the problem is achieved according to the invention in that the Plain bearings in the circumferential direction by positive locking and in the axial direction by a Snap connection is held. The plain bearing therefore only needs to be inserted into the im Unit housing provided bearing opening inserted and against the snap connection be pressed into this. Such an attachment of the plain bearing is particularly suitable for automatic production.

Eine besonders einfache Halterung des Gleitlagers ergibt sich nach einer Ausgestaltung der Erfindung dadurch, daß am Aggregategehäuse ein in eine Bohrung des Gleitlagergehäuses eingreifender Zapfen und diesem am Umfang der Lageröffnung gegenüberliegend eine Rastzunge angeformt sind. Bei der Montage des Gleitlagers wird dieses mit seiner Bohrung auf den Zapfen aufgesteckt und gegen die Rastzunge in die Lageröffnung gedrückt. Die Rastzunge schnappt hierbei über den Rand des Gehäuses des Gleitlagers und sichert dieses in axialer Richtung.A particularly simple mounting of the plain bearing results after an embodiment of the invention in that on the unit housing a into a bore of the sliding bearing housing engaging pin and this on the circumference of the bearing opening opposite a locking tongue are formed. When assembling the plain bearing this is placed with its hole on the pin and against the locking tongue pressed into the bearing opening. The locking tongue snaps over the edge of the housing of the plain bearing and secures it in the axial direction.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstand nachfolgend näher beschrieben.Based on an embodiment shown in the drawing the subject of the application is described in more detail below.

Mit 1 ist in der Zeichnung das Gehäuse eines Gebläseaggregates bezeichnet. In diesem Gehäuse ist ein aus einem Ständer 2 und einem Läufer 3 bestehender Motor angeordnet. Das mit zwei Gebläserädern 4 versehene Wellenende des Motors ist in einem Kugellager 5 und das bürstenseitige Wellenende in einem Gleitlager 6 gelagert. Das Gleitlager 6 ist in einem Gehäuse 7 angeordnet. Um eine gute Wärmeabfuhr zu erreichen, besteht dieses Gehäuse 7 aus Metall. In einem umlaufenden Rand 8 des Gehäuses 7 ist eine Bohrung 9 vorgesehen, durch die ein am Gehäuse 1 angeformter Zapfen 10 hindurchgreift. Durch diesen Zapfen 10 wird das Gehäuse 7 in Umfangsrichtung gesichert. Auf der dem Zapfen 10 gegenüberliegenden Seite ist an dem Aggregategehäuse 1 eine Rastzunge 11 vorgesehen. Beim Einsetzen des Gleitlagers in das Aggregategehäuse wird diese Rastzunge 11 durch den Rand 8 des Gehäuses 7 radial nach außen gedrückt.1 with the housing of a fan unit is referred to in the drawing. A motor consisting of a stator 2 and a rotor 3 is located in this housing arranged. The shaft end of the motor, which is provided with two fan wheels 4, is shown in FIG a ball bearing 5 and the brush-side shaft end in a plain bearing 6. The slide bearing 6 is arranged in a housing 7. To have good heat dissipation too reach, this housing 7 is made of metal. In a circumferential edge 8 of the Housing 7, a bore 9 is provided through which an integrally formed on the housing 1 Pin 10 engages through it. Through this pin 10, the housing 7 is in the circumferential direction secured. On the side opposite the pin 10 is on the unit housing 1 a locking tongue 11 is provided. When inserting the plain bearing into the unit housing this latching tongue 11 is pressed radially outward by the edge 8 of the housing 7.

Sobald das Gehäuse 7 in seine Endstellung gelangt, schnappt die Rastzunge 11 wieder nach innen und legt sich hinter den umlaufenden Rand 8. Damit ist das Gleitlager auch in axialer Richtung ausreichend gesichert.As soon as the housing 7 reaches its end position, the locking tongue snaps 11 back inwards and lies behind the circumferential edge 8. That is that Plain bearings are also adequately secured in the axial direction.
