Abstract

A shaft-mounting arrangement for use in mixing containers of household mixers includes a carrier body which is mounted on the bottom wall of the mixing container and penetrates therethrough from the interior to the exterior of the container. The carrier body bounds a passage in which there is accommodated a friction bearing which, in turn, is mounted on the above-mentioned shaft. A respective cap is connected to and overlaps each of the end faces of the carrier body and has an aperture through which the shaft extends out of the passage. An annular lubricant-accumulating groove is bounded by the bearing and the carrier body at that end of the latter which is located within the container, and the associated cap has an offset region which is juxtaposed with the groove at a distance therefrom. The other cap has a lubricant-accumulating space therein, and a lubricant-permeable body is accommodated in the accumulating space and contacts the bearing at that end thereof which is located outside the container. Flow-directing disks are mounted on the shaft for joint rotation therewith, being located respectively adjacent the axial ends of the bearing.
