FIELD: mechanics.
SUBSTANCE: invention relates to packing. The magnetic fluid packing comprises a permanent magnet and pole attachments to make with the shaft a gap filled with magnetic fluid. The surfaces that form the aforesaid gap are furnished with magnetic flux concentrators representing teeth, ledges or those formed by mating grooves. The magnetic flux concentrator side surfaces represent arcs arranged so that the adjacent concentrators form a groove, its axial section representing an R-radius semi-circle with its center being located on the opposite smooth surface or on the gap axis if the said concentrators are arranged on both surfaces. Note that concentrator spearhead is furnished with site t parallel to the gap axis.
EFFECT: higher-reliability packing.
