Through using a speed regulation system formed by a groove cam, a planetary gear train, a clutch and a speed regulation driving motor, the magnetic coupler is divided into two series: an air-cooling K-type-groove-cam planetary-gear-train combined electric speed-regulation disc-type magnetic coupler (a FTK series) and a liquid-cooling K-type-groove-cam planetary-gear-train combined electric speed-regulation disc-type magnetic coupler (a YTK series). In the invention, an economically feasible method is provided for speed regulation and energy saving of the mechanical equipment.
Description
Technical field
Power transmission, energy-saving and emission-reduction, dynamic equipment, magnetic drive.
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 magnetic drive product just emerges in an endless stream, magnetic drive pump, magnetic bearing, magnetic coupling, magnetic-gear etc.Be 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, magnetic drive product is just rapidly developed application.
Magnetic coupling has driven product independent as since the development of independent branch from magnetic drive pump isodynamic, there is panoramic product, but be all 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 (the 6000KW of picture thermal power plant, 1496r/min), secondary air fan (4550KW, 1495r/min), coal crusher (1200KW, 490r/min) and steel mill, mining site the dynamic equipment such as large fan, prior art and product all cannot meet practical application request.
Energy-saving and emission-reduction are current active demands.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.Frequency converter is shorter for useful life, and adaptive capacity to environment is poor, and take up an area space greatly, maintenance needs is high, and high voltage converter failure rate is then higher, poor reliability.Having carried out at present grooved cam mechanism speed governing magnetic coupling (cartridge type and disc type) that applies because of reasons in structure is of limited application, and expensive.Liquid cooling 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 poorer, and liquid cooling speed governing 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 the technical method finding the speed governing of a kind of disc electromagnetic coupling, the two large serial K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler of extending out along with this technical method---air-cooled K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler (FTK series), liquid cooling K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler (YTK series).
Accompanying drawing explanation
Fig. 1 is air-cooled K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler (FTK series), liquid cooling K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler (YTK series) adds casing, cooling fluid is by pipeline turnover on shell, force liquid cooling, the speed governing driven wheel of speed governing is assemblied in enclosure interior.
K type grooved cam planet circular system combination motor speed governing 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 patch fixed disk, and 3 is grooved cam planet circular system combined speed regulating mechanism, 6 is interior center driving axle, and 9 is outer center driving axle.
In two large serial K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler, inductive disks 1 and 5 is connect by caging bolt and forms external rotor with outer center driving axle 9, magnetic patch fixed disk 2 and 4 is connected on interior center driving axle 6, forms internal rotor together with grooved cam planet circular system combined speed regulating mechanism 3.The center driving axle of interior center driving axle 6, outer center driving axle 9 and load and prime mover connects and uses key connecting, and expansion set also can be adopted to connect.
During the work of magnetic coupling, magnetic coupling internal rotor, grooved cam planet circular system combined speed regulating mechanism and speed governing driven wheel synchronous high-speed rotate, when speed governing, clutch engages, speed governing drive motors drives the rotation of speed governing driven wheel, speed governing driven wheel drives main central gear 3-14 rotation, due to the effect of differential, sectional center gear 3-12 starts rotation, thus drive roller stationary magazine creel 3-6 rotation, roller stationary magazine creel rotates and is moved along the curved grooves of grooved cam 3-4 by driven roller 3-5, due to the axial non-displacement of roller stationary magazine creel 3-6, so grooved cam will be subjected to displacement vertically, thus the distance (magnetic Field Coupling gap) changed between magnetic patch fixed disk and inductive disks, to reach the object (change in 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. 2 is A-A cutaway view.
Figure 3 shows that grooved cam planet circular system combined speed regulating mechanism, spacing back-up ring 3-1 is used for ensureing that synchronizing bar 3-3 axial endplay can not occur, and 3-2 is fine setting spring, and 3-4 is grooved cam, and 3-5 is roller, and 3-8 is synchronizing bar retainer.3-14 is main central gear, 3-12 is sectional center gear, 3-13 is planetary gear, 3-26 is planet stent, 3-19 is main support, 3-17,3-23,3-7 are bearing.
Figure 4 shows that magnetic patch fixed disk 2, know and given expression to powerdriven mode---semiaxis, also show the distribution situation of magnetic patch.
Figure 5 shows that magnetic patch fixed disk 4, it direct and interior center driving axle 6 can not carry out power transmission, but can slide axially, and magnetic patch fixed disk 4 relies on three synchronizing bar 3-3 to carry out driving coupling, also show the distribution situation of magnetic patch.
Fig. 6 is the speed governing drive scheme schematic diagram of air-cooled K type grooved cam planet circular system combination motor speed governing disc type magnetic coupler (FTK series).
Figure 7 shows that FTK series magnetic coupling takes off the structural representation of inner two supports bearing, connect between power transmission shaft and adopt expansion set, other series also can be done like this, but this scheme only can be used on low year situation and axle alters very small situation, reason is as follows: inductive disks 1 and 5 is connect by caging bolt and forms external rotor with outer center driving axle 9, magnetic patch fixed disk 2 and 4 is connected on interior center driving axle 6, internal rotor is formed together with grooved cam planet circular system combined speed regulating mechanism 3, inner and outer rotors is not in contact with each other, but owing to being difficult to the depth of parallelism ensureing inductive disks and magnetic patch fixed disk during assembling, so alternate stress (effect of magnetic Field Coupling additional bending moment) can be caused to motor center axle bearing supporting place and supporting place of load transmission axle bearing, so that axle excessive wear was lost efficacy.In addition, the impact that axle is altered can cause bumpy running, can cause the accident time serious.Generally speaking, this kind of scheme will be cautious use of.
