Abstract
The invention relates to a motor rotor, particularly to an anti-dilated motor rotor. The motor rotor includes a rotating shaft, an iron core and magnetic steel; the iron core is disposed on the rotating shaft; the magnetic steel is disposed in the iron core; the iron core is disposed in a protective cover; rollers are actively connected to upper and lower ends in the protective cover; the iron core is clamped in the middle by the two rollers; and a heat dissipating hole is disposed in the protective cover. According to the invention, the structure of the motor rotor is enabled to be more stable and less likely to dilate, the service life of the motor rotor is extended, the cost is saved, and the efficiency is improved.
Description
Technical field
The present invention relates to a kind of rotor, especially a kind of anti-expanding rotor.
Background technology
Conventionally, the spinning solution of motor is all to interact between the induced field being produced by the rotating magnetic field producing in stator and rotor, rotor often will run up, the impact of centrifugal force because it is easy in High Rotation Speed, rotor core is expanded, thereby affected the normal operation of motor.
Summary of the invention
Hold expansive deficiency in order to overcome existing rotor, the invention provides a kind of anti-expanding rotor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-expanding rotor, comprise rotating shaft, iron core and magnet steel, and rotating shaft is provided with iron core, and magnet steel is placed between iron core, and iron core is placed in protective cover.
According to another embodiment of the invention, further comprise that roller bearing is movably connected in upper and lower two ends in protective cover, in the middle of two roller bearings are held in iron core clamp.
According to another embodiment of the invention, further comprise that protective cover is provided with louvre.
The invention has the beneficial effects as follows, this rotor can make structure more firm, thereby is not easy expansion, has extended the useful life of rotor, has saved cost, has improved effect.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is a kind of structural representation of anti-expanding rotor;
1. rotating shafts in figure, 2. iron core, 3. magnet steel, 4. protective cover, 5. roller bearing, 6. louvre.
Embodiment
If Fig. 1 is a kind of structural representation of anti-expanding rotor, a kind of anti-expanding rotor, comprise rotating shaft 1, iron core 2 and magnet steel 3, rotating shaft 1 is provided with iron core 2, magnet steel 3 is placed between iron core 2, and iron core 2 is placed in protective cover 4, and roller bearing 5 is movably connected in the interior upper and lower two ends of protective cover 4, in the middle of two roller bearings 5 are clamped in iron core 2, protective cover 4 is provided with louvre 6.
First iron core 2 is placed in protective cover 4, then rotating shaft 1 is passed to protective cover 4 and iron core 2, in the middle of roller bearing 5 in protective cover 4 is clamped in iron core 2, in the time that iron core starts to rotate, roller bearing 5 can make friction reduce to minimum in the situation that keeping iron core 2 not expand, and the louvre 6 on protective cover 4 can prevent that temperature of rotor is too high, this rotor can make structure more firm, thereby is not easy expansion, has extended the useful life of rotor, save cost, improved effect.
