the bellows enclosed cavities lubricant are accommodated, so that a permanent lubrication of the bearing sliding surfaces is guaranteed. Finally, the bearing inner ring can rotate in the outer ring without the risk of a * malfunction or there is wear of the bearing seal.

An exemplary embodiment of the innovation is shown in the drawing. Show it:

Ifig. 1 shows a longitudinal section through one formed after the inflation Articulated plain bearings in the assembled state,

S ¹ Ig.- 2 one half of the camp according to Pig. 1 with the inner ring tilted to the maximum. .

The articulated plain bearing consists in a known manner of an outside Partially spherical inner ring 1 and a correspondingly hollow spherical outer ring 2 on the inside.

According to the innovation, the laterally protruding from the outer ring 2 sliding surfaces of the inner ring 1 are covered by bellows 3 bxls flexible material, for example made of plastic. The outer edges of these bellows are firmly connected to L-shaped profiled steel rings 4, which are fixed by snap rings 5 in front of the end faces of the outer ring 2. The outer edges of flat steel disks 6 are embedded in the inner edges of the bellows 3, the inner edges of which engage in annular grooves 7 of the inner bearing ring 1. These grooves 7 are limited to the outside by IPeder rings 8 which are spring-loaded onto the offset ends of the inner ring 1.

Claims (3)

Protection claims 1. Sealing device for articulated plain bearings with partially spherical outside Inner ring and an inner correspondingly hollow spherical outer ring, characterized in that the side from the outer ring (2) protruding sliding surfaces of the bearing inner ring (1) covered by bellows (3) made of flexible material are fixed on the one hand on the end faces of the bearing outer ring (2) and on the other hand with metal washers (6) are firmly connected, their inner edges in annular grooves (7) of the bearing inner ring (1). 2. Bearing sealing device according to claim 1, characterized in that that in the outer edges of the bellows (3) L-shaped profiled steel rings (4) are embedded, which by means of snap rings (5) in front of the end faces of the bearing outer ring (2) are specified. 3. Bearing sealing device according to claim 1, characterized in that that the annular grooves (7) of the bearing inner ring (1) are limited on the outside by 3 eder rings (8), which are spring-loaded onto the offset ends of the inner ring (1).
