The product of color color, but be all confined to the reason of configuration aspects, the dynamic equipment that can only be confined to middle low power, medium and small moment of torsion interval moves
In power transmission application, and expensive.As the primary air fan (6000KW, 1496r/min) of thermal power plant, overfire air fan (4550KW,
1495r/min), coal breaker (1200KW, 490r/min) and steel mill, the dynamic equipment such as large fan of mining site, prior art and
Product 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 machine the most efficiently
Structure speed governing magnetic coupling variable speed energy saving.Converter is shorter for service life, and adaptive capacity to environment is poor, takes up an area space greatly, safeguards and need
Asking high, high voltage converter fault rate is the highest, poor reliability.Carry out the grooved cam mechanism speed governing magnetic coupling (cylinder applied at present
Formula and disc type) it is of limited application because of reasons in structure, and expensive.Ye Leng grooved cam mechanism speed governing disc electromagnetic coupling can only be exerted oneself
Being applied to by force in the dynamic equipment of below 2500KW moderate rotation, air-cooled grooved cam mechanism speed governing disc electromagnetic coupling can only be applied to reluctantly
In the dynamic equipment of below 350KW moderate rotation.Cartridge type magnetic coupling is the most worse, liquid cool tone speed product can only be applied to reluctantly 800KW with
In the dynamic equipment of lower moderate rotation, and security reliability is the highest.

Four big series R type grooved cam electric speed regulation disc type magnetic coupler, all comprise following several part: label 1 and 5 in figure
For inductive disks, 2 and 4 is magnetic piece fixed disk, and 3 and 9 is inner rotor motor grooved cam speed adjusting gear, and 6 is that electric speed regulation is special
High speed swivel coupling.
For series connection R type grooved cam electric speed regulation disc type magnetic coupler (CFTR series, CYTR series), can go here and there in theory
Joining any group, can determine as required, Fig. 2 show 3 groups of series connection, and in figure, label 8 is inductive disks and the magnetic piece of middle series connection
Fixed disk.
In four big series R type grooved cam electric speed regulation disc type magnetic coupler, all of inductive disks is made up of caging bolt connection
Outer rotor, all of magnetic piece fixed disk is connected on center driving axle, forms together with inner rotor motor grooved cam speed adjusting gear
Internal rotor, in center driving axle live wire connect motor (motor stator, magnetic piece fixed disk and center rotating shaft synchronous axial system) and
The internal rotor (with center driving axle geo-stationary) of electric speed regulation specialized high-speed swivel coupling, electric speed regulation specialized high-speed swivel coupling
Outer rotor connected external power source by two-way switch.Two-way switch controls to enter the sense of current of motor, thus changes motor steering.
Motor internal rotor rotates and is moved along the curved grooves of grooved cam 3-19 by driven roller 3-18, owing to motor inner rotor shaft is to nothing
Displacement, so grooved cam will be subjected to displacement vertically, thus changes distance (the magnetic field coupling between magnetic piece fixed disk and inductive disks
Close gap), with reach variable speed energy saving purpose (change of magnetic field coupling gap, will cause the change of magnetic coupling inner and outer rotors slip,
The namely change of input and output rotating speed).
Fig. 3 show the distribution situation of magnetic piece, and in figure, label 1 is three synchronizing bars of inner rotor motor, it is ensured that motor stator with
Magnetic piece fixed disk synchronous axial system.
Fig. 4 is inner rotor motor grooved cam speed adjusting gear, and 3-4,3-22 are thread seal plug, and 3-3 is synchronizing bar, 3-2
For spacing back-up ring, 3-12 is contact material, and 3-11 uses electrically insulating material to inlay the combinative structure of contact material, 3-8,

For roller, 3-19 is grooved cam (with motor center axle consubstantiality), and motor is produced in batches by specialized factory.
Fig. 5 is series connection R type grooved cam electric speed regulation disc type magnetic coupler inner rotor motor grooved cam speed adjusting gear, 9-1
For lining.
Fig. 6 is series connection in the middle of series connection R type grooved cam electric speed regulation disc type magnetic coupler (CFTR series, CYTR series)
Inductive disks and magnetic piece fixed disk, inductive disks is positioned on the connection screw rod of magnetic coupling outer rotor by positioning sleeve 8-1,8-2, stop collar
Magnetic piece fixed disk has been slided position-limiting action on center driving axle by 8-8.
Fig. 7, Fig. 8, Fig. 9, Figure 10 show electric speed regulation specialized high-speed swivel coupling, use modular series connection structure, can go here and there
Joining any passage, be triple channel shown in Fig. 7, two ends sealing ring 6-20,6-21 can use the material such as tungsten carbide, graphite, in
Between 6-5,6-7,6-8,6-24,6-25 of live wire access portion can use electrically insulating material, 6-22 uses contact material,
6-23 uses electrically insulating material to inlay the combinative structure of contact material, and 6-14 is spring, for equilibrium contact pressure, at spring
Guide finger 6-15 spring is played guide and limit effect, when preventing from turning round at a high speed, spring lost efficacy under centrifugal action.
Figure 11, Figure 12, Figure 13 show the scheme in groups of electric speed regulation specialized high-speed swivel coupling, use modular series connection knot
Structure, any passage of can connecting, is triple channel shown in Figure 11, and its internal rotor is connect each several part by bolt 4, then connects with revolution
The outer rotor of head assemblies an entirety, then is fixed on center driving axle with location screw, and internal rotor and center driving axle are same
Step rotates, and its outer rotor transfixion, to connect external power source.
Figure 14, Figure 15 are inductive disks, protruding blade is distributed, has helped heat radiation in card.During unknown device rotation direction, can be selected for figure

Sound.
Figure 16 show the manufacturing process (can directly carry out Small and Deep Hole Machining) of elongated hole in center driving axle and uses aluminium extruded type
Molding, then carries out nested with center driving axle, with simplified processing process, reduces manufacturing cost.
Figure 17 show FTR series magnetic coupling and takes off the structural representation of internal two supports bearing, couples and use expansion set between power transmission shaft,
Other series also can do so, but this scheme only can be used on low load situation and axle alters the most small situation, and reason is as follows: sensing
Dish 1 and 5 is formed outer rotor by bolted on connection, and magnetic piece fixed disk 2 and 4 and speed adjusting gear 3, swivel coupling 6 are by center driving
Axle connects composition internal rotor, and inner and outer rotors is not in contact with each other, but it is difficult to ensure that inductive disks is parallel with magnetic piece fixed disk during owing to assembling
Degree, so can (magnetic field coupling is additional to causing alternate stress at motor center axle bearing supporting and at load transmission axle bearing supporting
The effect of moment of flexure) so that axle excessive wear was lost efficacy.Additionally, the impact that axle is altered can cause bumpy running, can cause time serious
Accident.Generally speaking, this kind of scheme to be cautious use of.
