Abstract

A magnetic-liquid sealing device has permanent magnet magnetized in radial direction, circular pole tip with circular section that surrounds peripheral surface of the magnet, magnetic liquid held between the pole tip and the shaft made of magnetic-soft material. Magnetic flux formed with magnet is directed in direction normal to peripheral surface of the magnet where magnetic liquid is held between the pole tip and the shaft. Between the end surfaces of the pole tip and permanent magnet placed one in front of another non-magnetic ring is installed. Between the surface of permanent magnet directed to the shaft and the shaft additional circular pile tip is installed, this forms gap filled with magnetic liquid. The magnet is made component, of several magnets placed uniformly in circle. Permanent magnet at the outer side is closed with non-magnetic circular cover forming gap with the shaft. At the outer side of the pole tip circular non-magnetic intermediate cover is installed, this forms gap with the shaft. On the surfaces of pole tips that form gap with the shaft concentrators of magnetic flux are threaded as lugs. On the surface of non-magnetic intermediate cover and non-magnetic circular cover that form gap with the shaft circular grooves are threaded. Magnetic flux formed with magnet is directed in direction normal to peripheral surface of the magnet. Cavity formed with circular section of pole tip, shaft, additional pole tip and non-magnetic ring includes magnetic liquid.
