Description
Technical field
Power transmission, energy-saving and emission-reduction, dynamic equipment, magnetically-actuated.
Background technology
From human use ground Magnetic driving invention compass, the research on utilization of magnetic field energy just never stopped. Along with the development of modern theory of magnetism, the application in the industry of magnetically-actuated product just emerges in an endless stream, magnetic drive pump, magnetic bearing, magnetic coupling, magnetic-gear etc. Being limited to the restriction of magnetic material, Drive Technology slower development, until nineteen eighty-three, Chinese invention high performance permanent magnetic materials neodymium iron boron, magnetically-actuated product is just rapidly developed application.
Magnetic coupling has driven product independent as since independent branch's development from magnetic drive pump isodynamic, occur in that panoramic product, but all it is confined to the reason of configuration aspects, can only be confined in the dynamic equipment dynamic transmission application in middle low power, medium and small moment of torsion interval, and expensive. Primary air fan (6000KW as thermal power plant, 1496r/min), overfire air fan (4550KW, 1495r/min), coal breaker (1200KW, 490r/min) and dynamic equipment, prior art and the product such as large fan of steel mill, mining site all cannot meet practical application request.
Energy-saving and emission-reduction are current urgent needss. Dynamic device energy conservation, has variable-frequency speed-adjusting energy-saving and grooved cam mechanism speed governing magnetic coupling variable speed energy saving at present more efficiently. Converter is shorter for service life, and adaptive capacity to environment is poor, takes up an area space greatly, and maintenance needs is high, and high voltage converter fault rate is then higher, poor reliability. Current grooved cam mechanism speed governing magnetic coupling (cartridge type and disc type) carrying out applying is of limited application because of reasons in structure, and expensive. Ye Leng grooved cam mechanism speed governing disc electromagnetic coupling can only be applied in the dynamic equipment of below 2500KW moderate rotation reluctantly, and air-cooled grooved cam mechanism speed governing disc electromagnetic coupling can only be applied in the dynamic equipment of below 350KW moderate rotation reluctantly. Cartridge type magnetic coupling is then worse, and liquid cool tone speed product can only be applied in the dynamic equipment of below 800KW moderate rotation reluctantly, and security reliability is not high.
Summary of the invention
The present invention focuses on and finds a kind of technical method solving the dynamic equipment variable speed energy saving of high-power, high torque, extend out along with this technical method four big series V-groove cam electric speed regulation disc type magnetic coupler air-cooled V-groove cam electric speed regulation disc type magnetic coupler (FTV series), liquid cold V-groove cam electric speed regulation disc type magnetic coupler (YTV series), air-cooled V-groove cam electric speed regulation disc type magnetic coupler of connecting (CFTV series), series connection liquid cold V-groove cam electric speed regulation disc type magnetic coupler (CYTV series).
Accompanying drawing explanation
Fig. 1 is air-cooled V-groove cam electric speed regulation disc type magnetic coupler (FTV series), liquid cold V-groove cam electric speed regulation disc type magnetic coupler (YTV series) adds casing, coolant is by pipeline turnover on shell, forced fluid is cold, and revolution conductive contact is placed in housing exterior at a high speed.
Fig. 2 is air-cooled V-groove cam electric speed regulation disc type magnetic coupler of connecting (CFTV series), series connection liquid cold V-groove cam electric speed regulation disc type magnetic coupler (CYTV series) adds casing, coolant is by pipeline turnover on shell, forced fluid is cold, and revolution conductive contact is placed in housing exterior at a high speed.
Four big series V-groove cam electric speed regulation disc type magnetic coupler, all comprise following several part: number in the figure 1 and 5 is inductive disks, and 2 and 4 is magnetic piece fixed disk, and 3 is external rotor electric machine grooved cam speed adjusting gear, and 6 for turning round conductive contact at a high speed.
For series connection V-groove cam electric speed regulation disc type magnetic coupler (CFTV series, CYTV series), can connect in theory any group, can determining as required, Fig. 2 show 3 groups of series connection, and number in the figure 8 is inductive disks and the magnetic piece fixed disk of middle series connection.
In four big series V-groove cam electric speed regulation disc type magnetic coupler, all of inductive disks is formed outer rotor by caging bolt connection, all of magnetic piece fixed disk is connected on center driving axle, internal rotor is formed together with external rotor electric machine grooved cam speed adjusting gear, in center driving axle, (motor stator is fixed on center driving axle live wire connection motor, with center rotating shaft geo-stationary) and turn round at a high speed the carbon brush (with center driving axle geo-stationary) of conductive contact, the slip ring turning round at a high speed conductive contact connects external power source. Two-way switch controls to enter the sense of current of motor, thus changing motor steering. Motor outer rotor driven gear 3-6 rotation (gear drive), gear 3-6 rotates and is moved along the curved grooves of grooved cam 3-18 by driven roller 3-17, due to the axial non-displacement of gear 3-6, so grooved cam will be subjected to displacement vertically, thus the distance changed between magnetic piece fixed disk and inductive disks (magnetic field coupling gap), to reach the purpose (change of magnetic field coupling gap of variable speed energy saving, the change of magnetic coupling inner and outer rotors slip will be caused, the namely change of input and output rotating speed).
Fig. 3 and Fig. 4 is external rotor electric machine grooved cam speed adjusting gear, and the central shaft of motor can make hollow-core construction (being fixed on center driving axle with holding screw), in order to motor is produced in batches by specialized factory.
Fig. 5, Fig. 6 show and turn round conductive contact at a high speed, adopt modular construction, the quantity of slip ring is determined as required, it is three slip rings (can be six or arbitrarily individual) shown in figure, connect three wires, adapter ring 6-3, overcoat 6-4 adopt electrically insulating material, 6-5 is carbon brush, 6-6 is slip ring (being embedded in adapter ring 6-3), and 6-7 is fine setting spring (for equilibrium contact pressure), and 6-8 is wire, 6-9 is right end cap, 6-1 is left end cap, and 6-11 is bearing, and 6-15 is support. Carbon brush, external external power source is connect in slip ring. Carbon brush is assemblied on center driving axle 6-14, with center driving axle synchronous rotary. Slip ring 6-6 is embedded in adapter ring 6-3 and is internally formed stationary parts, is fixed on support 6-15, relies on the impact of bearing 6-11 quarantine center power transmission shaft high speed rotating. At a high speed revolution conductive contact is using carbon brush and slip ring as dynamic Contact, it is also possible to fill counter to carbon brush and slip ring, by connecing slip ring in carbon brush, and external external power source. Expanding overcoat 6-4 to periphery in Fig. 6, reinforced insulation protects.
Fig. 7, Fig. 8 are inductive disks, and in card, distribution has protruding blade, has helped heat radiation. During unknown device rotation direction, can be selected for shape shown in Fig. 7, as known equipment rotation direction, can be selected for the streamline shape shown in Fig. 8, increased heat dissipation capacity and reduced flow-disturbing noise. When heat dissipation capacity is enough, inductive disks use square position, shouldn't projection blade, to simplify manufacturing process.
Fig. 9 show distribution situation and the shape of magnetic piece on magnetic piece fixed disk, magnetic piece arc transition, it is to avoid by square caused induced field deformity.
Figure 10 show the manufacturing process (can be made directly Small and Deep Hole Machining) of elongated hole in center driving axle and adopts aluminium extruded type molding, then carries out nested with center driving axle, with simplified processing process, reduces manufacturing cost.
Figure 11 is the inductive disks and magnetic piece fixed disk connected in the middle of series connection V-groove cam electric speed regulation disc type magnetic coupler (CFTV series, CYTV series), inductive disks is positioned on the connection screw rod of magnetic coupling outer rotor by positioning sleeve 8-1,8-2, and magnetic piece fixed disk has been slided position-limiting action by stop collar 8-8 on center driving axle.
Figure 12 show FTV series magnetic coupling and takes off the structural representation of internal two supports bearing, couple between power transmission shaft and adopt expansion set, other series also can do so, but this scheme only can be used on low load situation and axle alters very small situation, reason is as follows: inductive disks 1 and 5 is formed outer rotor by bolted on connection, magnetic piece fixed disk 2 and 4 and external rotor electric machine grooved cam speed adjusting gear 3 connected to form internal rotor by center driving axle, inner and outer rotors is not in contact with each other, but it is difficult to ensure that the depth of parallelism of inductive disks and magnetic piece fixed disk during due to assembling, so motor center axle bearing supporting place and load transmission axle bearing supporting place can be caused alternate stress (effect of magnetic field coupling additional bending moment), so that axle excessive wear was lost efficacy. additionally, the impact that axle is altered can cause bumpy running, can cause the accident time serious. generally speaking, this kind of scheme to be cautious use of.
