DE2811014B2 - Arrangement for fastening a plain bearing - Google Patents

Description

The invention relates to an arrangement for fastening a slide bearing in the motor blower unit a vacuum cleaner is used to store the runner and with its with a circumferential edge provided sliding bearing housing is held in the circumferential direction by a form fit on the unit housing is.

Such an arrangement is known from DE-OS 21 44 109. Here, the plain bearing is secured by screws that Engage in threaded holes provided on the circumferential edge of the plain bearing housing on the unit housing attached.

From US-PS 39 59 848 a vacuum cleaner is known in which a rouerendt brush in one Plain bearing is stored. The plain bearing is in this vacuum cleaner by a separate Fec- ^ r, which with a circumferential edge of the plain bearing is snapped, held in its bearing seat.

In a known from DE-GM 75 25 742 bearing plate for eir.en vacuum cleaner fan motor is a Spherical plain bearings provided. This spherical plain bearing is through a clamp that is in a corresponding bearing bore is pressed in, held.

The invention is based on the object of creating an arrangement of the type mentioned at the beginning for fastening a slide bearing, in which the fastening of the slide bearing is possible without separately attachable fastening means.
The object is achieved according to the invention in that a pin engaging in a bore of the sliding bearing housing and a locking tongue opposite this are formed on the unit housing, the locking tongue engaging behind the sliding bearing housing at its circumferential edge

ίο When assembling the plain bearing, this is included with its hole provided on the circumferential edge placed on the pin and against the locking tongue pressed The locking tongue snaps over the edge of the plain bearing housing and secures it in

is axial direction. Such an attachment of the plain bearing is particularly suitable for automatic production.

The subject of the application is based on an exemplary embodiment shown in the drawing described in more detail below.

With J in the drawing, the housing is one Motor blower unit referred to. In this unit housing is one of a stand 2 and a Runner 3 arranged existing motor. The shaft end of the motor is provided with two fan wheels 4 in a ball bearing and the shaft end on the brush side stored in a plain bearing k. The slide bearing 6 is arranged in a slide bearing housing 7. To be good To achieve heat dissipation, this plain bearing

jo home 7 made of metal. In a circumferential edge 8 of the Plain bearing housing 7, a bore 9 is provided through which an integrally formed on the plain bearing housing 1 Pin 10 engages through it. The plain bearing housing 7 is secured in the circumferential direction by this pin 10.

J5 is on on the side opposite pin 10 the unit housing 1 is provided with a latching tongue 11. When inserting the plain bearing into the unit housing, this locking tongue 11 is through the edge 8 of the Plain bearing housing 7 pressed radially to sweet.

As soon as the plain bearing housing 7 reaches its end position, the latching tongue 11 snaps inwards again and lies behind the circumferential edge 8. This means that the plain bearing is also sufficient in the axial direction secured.
