, in assembling, magnetic conduction core and the second shaft part 30 axial compression, mainly by high intensity axle sleeve 10 interference connection, the second shaft part for section 30
30 couple together.
This rotating shaft is high speed permanent magnet motor rotor, by turn first shaft part 20, axle sleeve 10, annular magnetic steel, magnetic conduction core, the second axle
Section 30 composition.Wherein annular magnetic steel is enclosed within magnetic conduction core.Rotor is that rotating shaft is made up of three sections of splicings, using alloy sleeve and three sections
Interference fit between assembly carrys out transmitting torque.
The left end being cased with the magnetic conduction core of annular magnetic steel carries out positioning connection, first axle by concaveconvex structure and the first shaft part 20
Section 20 is integrally formed with the magnetic conduction core being cased with annular magnetic steel, then by sheath, said modules and the second shaft part 30 has been connected
Come.Magnetic conduction core adopts permeability magnetic material, and the section of one end of magnetic conduction core is provided with recess, and recess includes screwed hole and location hole, ring
Shape magnet steel adopts NdFeB material.Due to the magnet steel of parallel magnetization, all magnetic lines of force are by the center of circle all in one direction, mutually flat
OK, so for this annular magnetic steel, for ensureing the magnetic field sine that magnet steel produces, needing to adopt parallel magnetization.Annular magnetic steel is enclosed within
On magnetic conduction core, and section is all concordant with the end face at the left and right two ends of magnetic conduction core around.
Sheath is that axle sleeve 10 adopts nickel-base alloy, titanium alloy etc materials, sheath and the first shaft part 20, annular magnetic steel, second
Shaft part 30 is interference fit and is fitted and fitted with the left side of the second shaft part 30 in the right side with the first shaft part 20.
During assembling, first magnetic conduction core is passed through concaveconvex structure (recess 50 and connection bump) and carry out positioning even with the first shaft part 20
Connect, afterwards annular magnetic steel set is attached on magnetic conduction core.Due to there is gap between annular magnetic steel and magnetic conduction core, need to fill magnet steel
Glue, to fill gap, can coat magnet steel glue in magnet steel inwall or magnetic conduction core outer peripheral face, thus reaching the mesh of stationary annular magnet steel
's.Due to the certralizing ability of concaveconvex structure, the outer peripheral face of annular magnetic steel is overlapped with the outer peripheral face of the first shaft part 20, above-mentioned three
(magnetic conduction core, the first shaft part 20, annular magnetic steel) will form a rotor assembly.
Then the alloy sleeve that would be heated to preset temperature is quickly charged with the outer surface of above-mentioned rotor assembly, and rapidly will
Second shaft part 30 is attached in above-mentioned alloy sleeve, and natural cooling for a period of time, completes rotating shaft assembling, finally does overall place of magnetizing
Reason, completes high speed rotating shaft and makes.
Because high-speed electric expreess locomotive needs high temperature hot charging sheath, if using the magnet steel having magnetized, high temperature can lead to magnet steel to demagnetize.
So must magnetize to magnet steel using the magnet steel not magnetized, after bearing has assembled overall.
In the present embodiment, recess 50 is circular hole structure, is so capable of the first shaft part 20, the second shaft part 30 and leads
The radial positioning of magnetic core, as avoids the first shaft part 20, the second shaft part 30 and magnetic conduction core to occur eccentric as possible.Toroidal cavity is axially
Avoid gap it is ensured that after screw thread screws, the contact with magnet steel and rotating shaft extremity piece (the first shaft part 20, the second shaft part 30) of magnetic conduction core
Face is close to, presence very close to each other.If there is the presence in gap herein, the reduction of shaft stiffness can be led to, revolve at a high speed in rotating shaft simultaneously
When forwarding raw accident collision, the abnormal problems such as shaft bending can be led to easily, reduce rotating shaft reliability and service life.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
