61 type electric speed regulation disc type magnetic coupler of several structure types, all comprise following several part: label 1 and 5 in figure
For inductive disks assembly, 2 and 4 is magnetic piece fixed disk assembly, and 3 (arrive about realizing rotary motion in speed adjusting gear 3 for speed adjusting gear
The parts of transform linear motion, 61A type uses ball-screw, and 61B type uses lead screw, and 61C type uses grooved cam), 6
For revolution conductive contact (or electric speed regulation specialized high-speed swivel coupling) at a high speed.
For 61 type electric speed regulation disc type magnetic coupler of connecting, can connect in theory any group, can determine as required, Fig. 2,
Fig. 4, Fig. 6 show 3 groups of series connection, and in figure, label 8 is inductive disks assembly and the magnetic piece fixed disk assembly of middle series connection.
In 61 type electric speed regulation disc type magnetic coupler of several structure types, all of inductive disks assembly is by caging bolt joint group
Becoming outer rotor, all of magnetic piece fixed disk component string is associated on center driving axle, forms internal rotor, center together with speed adjusting gear
In power transmission shaft, live wire connects motor and turns round at a high speed the brush of conductive contact, and the slip ring of revolution conductive contact connects external electrical at a high speed
Source.Two-way switch controls to enter the sense of current of motor, thus changes motor steering.Motor driven ball screws assembly or slip
Lead screw assembly or grooved cam assembly, make rotary motion be changed into linear motion, drives magnetic piece fixed disk assembly to slide axially,
Thus change the distance (magnetic field coupling gap) between magnetic piece fixed disk and inductive disks, to reach purpose (the magnetic field coupling of variable speed energy saving
Close the change in gap, the change of magnetic coupling inner and outer rotors slip, the namely change of input and output rotating speed will be caused).
Fig. 7 show magnetic piece fixed disk assembly.Figure clearly illustrates the distribution situation of magnetic piece.
Fig. 8, Fig. 9 show the speed adjusting gear 3 of 61A type electric speed regulation disc type magnetic coupler, by motor, ball-screw assembly
Deng composition.In figure, label 3-1,3-4 are ball-screw assembly, and 3-2 is motor, and 3-3 is auxiliary stand.
Figure 10 show the speed adjusting gear 3 of 61B type electric speed regulation disc type magnetic coupler, by groups such as motor, lead screw assemblies
Become.In figure, label 3-1,3-4 are lead screw assembly, and 3-2 is motor, and 3-3 is auxiliary stand.
Figure 11 show the speed adjusting gear 3 of 61C type electric speed regulation disc type magnetic coupler, by groups such as motor, grooved cam assemblies
Become.In figure, label 3-1,3-4 are grooved cam assembly, and 3-2 is motor, and 3-3 is auxiliary stand.
Figure 12, Figure 13 show revolution conductive contact at a high speed, use modular construction, and the quantity of slip ring determines as required, figure
Shown in be three slip rings (they can be six or the most individual), connect three of the wires, adapter ring 6-3, overcoat 6-4 use electricity absolutely
Edge material, 6-5 is brush, and 6-6 is slip ring (being embedded in adapter ring 6-3), and 6-7 is for finely tuning spring (for equilibrium contact
Pressure), 6-8 is wire, and 6-9 is right end cap, and 6-1 is left end cap, and 6-11 is bearing, and 6-15 is support.Electricity is connect in slip ring
Brush, external external power source.Brush is assemblied on center driving axle 6-14, with center driving axle synchronous rotary.Slip ring 6-6 inlays
It is internally formed stationary parts at adapter ring 6-3, is fixed on support 6-15, rely on bearing 6-11 quarantine center power transmission shaft high-speed rotary
The impact turned.At a high speed revolution conductive contact is using brush and slip ring as dynamic Contact, it is also possible to fill counter to brush and slip ring, by electricity
Slip ring, external external power source is connect in brush.Overcoat 6-4 expands in Figure 13 periphery, and reinforced insulation protects, and eliminates
Left and right end cap is to simplify structure.
Figure 14, Figure 15 show inductive disks, protruding blade are distributed, to help heat radiation in card.During unknown device rotation direction, optional
By shape shown in Figure 14, such as known device rotation direction, can be selected for the streamline shape shown in Figure 15, disturb increasing heat dissipation capacity reduction
Flow noise.Heat dissipation capacity enough in the case of, inductive disks uses square position, shouldn't projection blade, to simplify manufacturing process.
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 the inductive disks assembly connected in the middle of series connection 61A/B/C type electric speed regulation disc type magnetic coupler and magnetic piece is fixed
Dish assembly, inductive disks assembly is positioned on the connection screw rod of magnetic coupling outer rotor by positioning sleeve 8-1,8-2, and stop collar 8-8 is to magnetic piece
Fixed disk assembly has slided position-limiting action on center driving axle.
Figure 18 show 61A type 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 assembly 1 and 5 is formed outer rotor by bolted on connection, and magnetic piece fixed disk assembly 2 and 4 is connected by center driving axle with speed adjusting gear 3
Connecing composition internal rotor, inner and outer rotors is not in contact with each other, but due to during assembling it is difficult to ensure that the depth of parallelism of inductive disks and magnetic piece fixed disk,
So can be to causing alternate stress (magnetic field coupling additional bending moment at motor center axle bearing supporting and at load transmission axle bearing supporting
Effect), so that axle excessive wear 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.
Figure 19, Figure 20, Figure 21, Figure 22 show electric speed regulation specialized high-speed swivel coupling, use modular series connection structure,
Can connect any passage, be triple channel shown in Figure 19, Figure 20, its internal rotor is connect each several part by bolt 6-29, then and
The outer rotor of swivel coupling assemblies an entirety, then is fixed on center driving axle with location screw, its internal rotor and center
Power transmission shaft synchronous axial system, its outer rotor transfixion, to connect external power source.Sealing ring 6-20,6-21 can use carbonization at two ends
The material such as tungsten, graphite, 6-5,6-7,6-8,6-24,6-25 of middle live wire access portion can use electrically insulating material,
6-22 uses contact material, and 6-23 uses electrically insulating material to inlay the combinative structure of contact material, and 6-14 is spring, uses
Carrying out equilibrium contact pressure, spring is played guide and limit effect by the guide finger 6-15 at spring, and when preventing from turning round at a high speed, spring is centrifugal
Lost efficacy under power effect.
Electric speed regulation specialized high-speed swivel coupling may be substituted for turning round conductive contact, electric speed regulation specialized high-speed swivel coupling at a high speed
Than revolution conductive contact at a high speed, there is more preferable waterproof and dustproof and explosion-proof performance, but its structure is complicated, manufactures difficulty, economy
Difference.
