  • Patent number: 4576488
    Abstract: A bearing bushing for a journal bearing of a brake shaft of a drum brake. One end of the bearing bushing, on the outside, is provided with a circumferential, annular grease recess for the introduction of grease. Branching off in the axial direction from this recess are distributing channels, and disposed as extensions thereof on the inside are lubricating channels which extend in the opposite axial direction. In order to improve the distribution of grease, and to improve the formation of a closed lubricating film, each distributing channel opens out into a hole, which are interconnected on the inside by a circumferential, first annular channel. The inner lubricating channels are disposed between the distributing channels, extend parallel thereto between the holes, and are connected to the first annular channel. The lubricating channels open out into a circumferential second annular channel, which is connected to at least one outlet channel.
