Traditional screw air compressor is caused to take up space greatly, cost is high.Existing screw air compressor uses single screw rod or twin-screw more, works as needs
When air compression ratio is big, more method using raising power of motor improves compression efficiency, and energy consumption is larger.
Utility model content
The purpose of this utility model be to overcome in the prior art air compressor machine screw rod because the external motor space-consuming of needs is big
The high technical problem with compressed air ratio high energy consumption when big of cost, and a kind of reasonable in design, saving space is provided, compression is imitated
The high screw rotor of driving integral type three of rate.
The technical scheme in the invention for solving the above technical problem is：One kind driving screw rotor of integral type three, bag
Driven screw, driving screw rod are included, the driven screw is connected with the driving screw rod；The driven screw is 2, and mutually
Do not contact, the driving screw rod includes dead axle, rotor, and the dead axle is connected with the rotor by shaft connector；It is described fixed
Axle interlude is provided with electric coil, and magnet steel is provided with the inside of the rotor.
Electric coil is in the energized state with producing magnetic moment of torsion between the magnet steel that is set on rotor, so as to which rotor driven turns
Dynamic, correspondingly, the driven screw being connected with driving screw rod is driven by driving screw rod, rotates in the lump.Air compressor machine can not
Realized with external motor power self-driven, saved the installing space of external motor, reduce production and installation cost.
The NS poles of the magnet steel are relative to dead axle center symmetric setting.
The magnet steel is ferrite magnetic steel, alnico magnet, rare earth permanent-magnetic material, Nd-Fe-B magnet steel, exceptional hardness permanent magnetism
Any of alloy.The magnet steel of the utility model embodiment can use one kind in existing all kinds of magnet steels, selection
It is various, improved beneficial to production technology.
The shaft connector includes being arranged on the axle sleeve at the dead axle both ends, being arranged on the axle of the axle sleeve radially outer
Hold and be arranged on the oil sealing at the bearing both ends.Set oil sealing lubricating oil can be fixed on into Bearing inner in Bearing outer, prevent
The only oil seepage in fixed-axis rotation.
The bearing, oil sealing are fixedly connected with the rotor.
The axle sleeve is fixedly connected with the dead axle.
The driven screw is connected to driving screw rod both sides, and the driving screw rod and the axle center of 2 driven screws exist
In approximately the same plane.Driven screw is distributed in driving screw rod both sides, and 3 screw rod shaft core positions are at grade, Ke Yiyou
Effect reduces vibration amplitude during compressor operation, makes compressor operation more stable.
The utility model compared with prior art, has advantages below and effect：Air compressor machine screw drive one is realized,
Installing space is saved, meanwhile, air compression is carried out using three screw rods, effectively improves compression efficiency, saves energy consumption.
Brief description of the drawings
Fig. 1 is the main structure diagram of the utility model embodiment 1.
Fig. 2 is Fig. 1 cross-sectional view.
In figure：1- dead axles, 2- driven screws, 3- axle sleeves, 4- oil sealings, 5- magnet steels, 6- electric coils, 7- bearings, 8- rotors.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, and following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Embodiment
The purpose of the present embodiment is to provide a kind of driving screw rotor of integral type three, including two driven screws, 2, masters
Dynamic screw rod, two driven screws 2 are distributed in outside driving screw rod, and connection is engaged with driving screw rod, and two driven screws 2 are mutual not
Contact.Driving screw rod includes dead axle 1, rotor 8, and driving screw rod also includes a set of magnetic and moves structure；Magnetic, which moves structure, includes the inner side of rotor 8
The fixed magnet steel 5 being sticked, the electric coil 6 for being enclosed on the interlude of dead axle 1.The both ends of dead axle 1 are respectively cased with 3 axle sleeves 3, respectively in axle sleeve 3
Oil sealing 4, bearing 7 are cased with outside, the both ends of the surface of bearing 7 are each provided with an oil sealing 4, and the main function of oil sealing 4 is the profit of fixing bearing 7
Lubricating oil is only in bearing 7.Connected between outer layer rotor 8 and dead axle 1 by bearing 7, axle sleeve 3, oil sealing 4 etc..
In compressor operation, when both electric coil 6 is powered, moment of torsion, rotor driven 8 are produced between electric coil 6 and magnet steel 5
Rotate, driven screw 2 enters operating condition under the driving screw rod driving of engagement.Rotor 8 rotates can be via sensor by signal
Controller is input to, signal reaction is the location of rotor 8, and controller makes phase to these signals by judging afterwards
The output answered, and corresponding coil electricity is given, electric coil generates magnetic field after being powered, and the effect of power is just produced with magnet steel 5, causes
Magnet steel 5 is set to be rotated with respect to fixed-axis rotation, rotor 8 one, sensor output signal just changes, controller output different directions
Electric current, and magnetic field caused by the output current once more with the magnetic field of magnet steel 5 produce magnetic force effect（Identical charges repel each other, the opposite sex
It is attracting）, as a result cause rotor 8 to rotate.Action does not stop to move in circles above, magnet steel 5 and the together continuous rotation, and band of rotor 8
Dynamic driven screw 2 rotates.Dead axle 1, axle sleeve 3, electric coil 6 in compressor operation not as rotor 8 rotates, bearing 7, oil sealing
