Abstract
The invention relates to a suspension ring overhanging magnetic suspension blast blower which comprises axial magnetizing big magnet rings (1), axial magnetizing small magnet rings (2), a shell (3), a main shaft (4), a motor stator (5), a motor rotor (6), a blast blower outer cover (7), a blast blower impeller (8) and the like, wherein the axial magnetizing big magnet rings (1) are installed at the two sides of the shell (3); the motor stator (5) is arranged at the inner side of the shell (3); the blast blower outer cover (7) is positioned at one end of the shell (3); the two axial magnetizing small magnet rings (2) are positioned at the inner sides of the two big magnet rings (1); the motor rotor (6) is arranged between the two axial magnetizing small magnet rings (2); the blast blower impeller (8) is installed at the outer side end of the small magnet ring; the motor rotor (6), the blast blower impeller (8) and the two axial magnetizing small magnet rings (2) are arranged on the main shaft (4) together; the lengths of the axial magnetizing small magnet rings (2) are longer than those of the big magnet rings (1); and the axial magnetizing small magnet rings (2) extend towards the outer sides in a symmetrical way.
Description
Affiliated technical field
The present invention relates to the overhanging magnetic suspension blower of a kind of suspended ring, this motor is the both sides that two big magnet rings of axial charging are installed in shell, and motor stator is installed in the middle of the side in the enclosure, and an end of shell is installed the blower outer cover; Two axial charging beads are installed in the inboard of big magnet ring, and rotor is between two beads, and blower wheel is at an end of bead, and blower wheel, rotor and two beads are installed on the main shaft jointly; The length of bead is greater than the length of big magnet ring, and symmetry stretches out, and can making so axially tries hard to keep partially holds equilibrium.Belong to the magnetic levitation technology field.
Background technique
At present, known to us, major diameter axial charging magnet ring is enclosed within the outside of minor diameter axial charging magnet ring, just can produce the radial suspension phenomenon.When but two magnet rings are nested together, there is axially power partially, can causes axial instability, so design in the past can't realize axial suspension.We have so just realized the balance of axial suspension with the length symmetry extend outwards of suspended ring now, utilize this magnetic suspension bearing, and the blower rotating part is all suspended, and just become the magnetic suspension blower.
Summary of the invention
Principle of the present invention is the both sides that two big magnet rings of axial charging are installed in shell, between the big magnet ring in side motor stator is installed in the enclosure, at its outboard end the blower outer cover is installed; Two axial charging beads are installed in the inboard of two big magnet rings, and the compressive plane of big bead is parallel; Rotor is installed in the middle of two beads, at the outboard end of bead blower wheel is installed, impeller, rotor and bead are installed on the main shaft jointly; The length of axial charging bead is greater than the length of big magnet ring, and symmetry stretches out.
Description of drawings
Fig. 1 is the radial section tectonic maps of the overhanging magnetic suspension blower of suspended ring of the present invention.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, the big magnet ring of axial charging (1), axial charging bead (2), shell (3), main shaft (4), motor stator (5), rotor (6), blower outer cover (7), blower wheel (8) etc.; Two big magnet rings of axial charging (1) are installed in the both sides of shell (3), and motor stator (5) is installed in shell (3) inboard, and blower outer cover (7) is installed in an end of shell (3); Two axial charging beads (2) are installed in the inboard of two big magnet rings (1), rotor (6) is between two axial charging beads (2), blower wheel (8) is installed in the outboard end of bead, and rotor (6), draught fan impeller (8) and two axial charging beads (2) are installed on the main shaft (4) jointly; Axial charging bead (2) length is greater than big magnet ring (1), and symmetry is extended laterally.
