DE2811014C3 - 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 rotating brush in one Plain bearing is stored. The plain bearing is in this vacuum cleaner by a separate spring, which is 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 a vacuum cleaner fan motor is a Spherical plain bearings provided. This spherical plain bearing is through a clamp that is in a corresponding bearing hole is pressed in, bent.

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 axial direction. Attaching the plain bearing in this way 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.

1 with the housing of a motor blower unit is referred to in the drawing. In this unit housing a motor consisting of a stator 2 and a rotor 3 is arranged. That with two Blower wheels 4 provided shaft end of the motor is in a ball bearing and the brush-side shaft end stored in a plain bearing 6. The slide bearing 6 is arranged in a slide bearing housing 7. To be good To achieve heat dissipation, there is this plain bearing housing 7 made of metal. A bore 9 is provided in a circumferential edge 8 of the plain bearing housing 7, through which a pin 10 formed on the unit housing 1 engages. Through this pin 10 is the plain bearing housing 7 secured in the circumferential direction.

On the side opposite the pin 10, a latching tongue 11 is provided on the unit housing 1. 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 outward.

4G As soon as the plain bearing housing 7 is in its end position arrives, the latching tongue 11 snaps inwards again and lies behind the circumferential edge 8. This is the plain bearing is also adequately secured in the axial direction.
