Description
Technical field
The invention belongs to a kind of compressor electric motor technology, particularly relate to a kind of fixing structure of iron core of compressor motor rotor with the fastening rotor core of secure component.
Background technology
In general, compressor drives the driving shaft rotation by rotor and finishes the compression process that compressor is inhaled, arranged gas.
Fig. 1 is the wherein cutaway view of an example of screw compressor, and Fig. 2 is the schematic diagram of existing screw compressor motor rotor core.
Structure with screw compressor is an example, and screw compressor is made up of following components.Pour into a certain amount of lubricating oil, the casing 1 of steam inlet pipe SP of UNICOM and blast pipe DP; Be arranged on casing 1 inner two ends up and down, play the main engine bed 2 and the auxiliary engine bed 3 of fixation; Be arranged on the drive motors 4 between main engine bed 2 and the auxiliary engine bed 3; Be inserted into drive motors 4 centers, run through main engine bed 2, thereby transmit the driving shaft 5 of the moment of torsion of drive motors 4; Combine with driving shaft 5, and be arranged on the upper end of main engine bed 2, be provided with involute shape in the top, be provided with the rotation whirlpool dish 6 of scrollwork 6a; Be fixed on main engine bed 2 above, with the scrollwork 6a engagement of rotation whirlpool dish 6, form a plurality of compression bin P, form the fixed eddy plate 7 of scrollwork 7a with involute shape; Combine with the back side of fixed eddy plate 7, distinguish the high-low pressure separator disc 8 of the space S 2 of the space S 1 that sucks gas and the gas that spues in the inside of casing 1; Combine with the neck back side of fixed eddy plate 7, prevent the check valve block 9 of the air-flow adverse current that spues.
Drive motors 4 by: be fixed on casing 1 inside, add the stator 4A of power supply from the outside; And leave the certain intervals configuration in stator 4A inside, interact with stator 4A and rotor rotated 4B constitutes.
Rotor 4B is wrapped with coil after multi-disc rotor core (not label) is amassed so that cylindrical layer is stacked in its outside winding wire ring recess, its two ends are fixed with rotor tip 4b, 4c.
Be provided with to offset in driving shaft 5 eccentric rotations the time circular arc weight balancing piece 4d, the 4e of the eccentric weight that causes at rotor upper end 4b and rotor bottom 4c.
The operation principle of screw compressor is as follows as mentioned above.
After the energized, driving shaft 5 is with drive motors 4 rotations.It is 6 corresponding to the rotation of this eccentric distance that coil in the rotation whirlpool, and rotation whirlpool dish 6 forms a plurality of compression bin P between fixed eddy plate 7 and scroll wraps 6a, 7a, and this compression bin P moves and the compression bin inner volume to the middle part along with the continuous rotating motion of rotation whirlpool dish 6.Along with the repetition of this process, can reach air-breathing and function exhaust.
At this moment, during driving shaft 5 rotation, the eccentric weight of upper end eccentric part can cause the situation that the vibration of compressor increases the weight of, but by weight balancing piece 4d, 4e are set can offset eccentric weight of the top and bottom of rotor 4B off-centre, reduces the vibrations of compressor.
At present, the rotor 4B of drive motor for compressor, its two ends are fixed by rotor tip 4b, 4c usually.With reference to Fig. 2 as can be known, uniformly between the winding wire ring recess of rotor core and drive shaft hole be formed with most heat radiation oilholes.The stacked long-pending rotor core of cylindrical layer is pasted together with adhesive.Radiating effect is poor, and complex process is time-consuming.
Summary of the invention
The present invention provides a kind of fixing structure of iron core of compressor motor rotor with the fastening rotor core of secure component for solving the technical problem that exists in the above-mentioned technology.
The technical scheme that the present invention takes for the technical problem that exists in the above-mentioned technology of solution is:
A kind of fixing structure of iron core of compressor motor rotor of the present invention comprises that the multi-disc iron core is with the stacked long-pending inboard stator that forms the winding wire ring recess that constitutes of cylindrical layer; The multi-disc iron core forms the winding wire ring recess with the stacked long-pending formation of the cylindrical layer outside, the uniform rotor that is formed with most heat radiation oilholes between the winding wire ring recess of iron core and drive shaft hole; It is fastening with each the heat radiation oilhole in the stacked long-pending multi-disc iron core of cylindrical layer to pass rotor with secure component; The secure component that passes rotor core heat radiation oilhole is to have preseting length " Contraband " shape metal card; The secure component that passes rotor core heat radiation oilhole also can be to have preseting length, and diameter is slightly less than the tubular rivet of heat radiation oilhole diameter.The secure component that passes rotor core heat radiation oilhole also can be to have preseting length, and diameter is slightly less than the hollow fastening bolt that has nut of heat radiation oilhole diameter.
Advantage and good effect that the present invention has are: fixing structure of iron core of compressor motor rotor of the present invention, and by with secure component that the multi-disc iron core of rotor is fastening, technology is simple, and good heat dissipation effect is saved man-hour.
