    • 专利摘要:
    A contact free magnetic bearing in which a magnetic body is disposed between a pair of opposed magnetic poles so that the magnetic field between the poles is in supporting relation to the magnetic member disposed therebetween. Deviation of the magnetic member relative to the magnetized poles is detected and the strength of the magnetic field between each of the poles of the magnetic member is varied to establish influences acting between the poles and the magnetic member tending to restore the condition of equilibrium.

    direction of flow of permanent magnets.
    FIG. 1 is a sketch of a magnetic support; Fig 2 is the same for rotating bodies; in fig. 3 is the same for bodies performing a straight-line motion; FIG. 4 is a diagram of a magnetic support in longitudinal section for rotating bodies; in fig. 5 is a variant of the magnetic support.
    The magnetic support contains movable 1 and fixed 2 and 2 elements. The movable element 1 is partially made of magnetized material and is located between the magnetic pole lugs 3 and 3 of different polarity, which are placed on permanent magnets of the stationary element 2 the air gap is installed conductive element 4 and 4 of the individual conductors forming electrical circuits. The direction of the current in these circuits is opposite to one another.
    For palpation, in order to determine the deviation from the required position, known sensing devices are used, the output signals of which act on the control current in the conductive elements 4 and 4.
    Due to the opposite direction of movement of the control current in the conductive elements in the area of the air gap, it is achieved that the action of the control current on the preliminary 1 г1 suppression is neutralized, and that the rigidity is supported when the set element deviates from the equilibrium position,. regardless of the direction of deviation, it always changes in the same way. The control of forces in the magnetic support is based on the change in the distribution of the scattering flux at the points of transition from the high magnetic permeability zone to the low magnetic permeability zone, especially in the air gap zone. Magnetic lines of force received from the passage of the control current through the conductive elements are superimposed on the line of the scattered field in the zone of the gap, so that the flux density of the scatter from one edge of the magnetized part of the element at one air gap increases control current movement is reduced. Thus, it is possible to compensate for the interfering forces acting on those established by the body’s magnetic forces.
    In the embodiments of the proposed support shown in FIG. 2, 4 and 5, the conductive element 4 is in the form of a closed ring, and the movable element 1 is a rotating body. The increase in the radial force of the support is achieved by the fact that the magnetizable part of the element 1 and the pole pieces 3 of the magnetic system are made of axially arranged tubular elements having the same diameter. With this shape of the magnetizable part and the pole pieces, it is possible
    to use the space bounded by the support elements for other technical purposes, for the return closure of the magnetic flux, the presence of the flux-conducting element 5 is provided.
    In the embodiment of the proposed support shown in FIG. 3, the movable element is designed in the form of a rail located perpendicular to the magnetic flux inside the air gap between the pole pieces of the magnetic system.
