Fig. 7 is air-cooled LI type single cylinder fluid speed governing disc type magnetic coupler (FTLI series), and liquid cooling LI type single cylinder fluid speed governing disc type magnetic coupler (YTLI series), adds casing, force liquid cooling, and cooling fluid is by the pipeline turnover on shell.
Figure 10 is the air-cooled LI type single cylinder fluid speed governing disc type magnetic coupler of series connection (CFTLI series), series connection liquid cooling LI type single cylinder fluid speed governing disc type magnetic coupler (CYTLI series), add casing, force liquid cooling, cooling fluid is by the pipeline turnover on shell.
Eight large serial LH/I type single cylinder fluid speed governing disc type magnetic coupler, all comprise following several part: number in the figure 1 and 5 is inductive disks assembly, and 2 and 4 is magnetic patch fixed disk assembly, and 3 is single cylinder fluid speed adjusting gear, and 6 is high speed rotary joint.
For series connection LH/I type single cylinder fluid speed governing disc type magnetic coupler (CFTLH/I series, CYTLH/I are serial), can connect in theory any group, can determine as required, be 3 groups of series connection shown in Fig. 8 and Figure 10, number in the figure 8 is inductive disks assembly and the magnetic patch fixed disk assembly of middle series connection.
In eight large serial LH/I type single cylinder fluid speed governing disc type magnetic coupler, all inductive disks assemblies are connect by caging bolt and form external rotor, all magnetic patch fixed disk component string are associated on center driving axle, internal rotor is formed together with single cylinder fluid speed adjusting gear, runner is had to connect high speed rotary joint in center driving axle, the internal rotor of high speed rotary joint and center driving axle geo-stationary, the external rotor of high speed rotary joint connects external hydraulic or pneumatic circuit.Hydraulic control one-way valve or gas control unidirectional valve and electromagnetically operated valve etc. control the turnover of fluid, thus change piston move axially direction, piston rod (being fixed together with magnetic patch fixed disk assembly) drives magnetic patch fixed disk assembly centrally propeller shaft slip, thus the distance (magnetic Field Coupling gap) changed between magnetic patch fixed disk assembly and inductive disks assembly, 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), install lever lazy-tongs additional and ensure two symmetrical magnetic patch fixed disk component synchronization counter motions.
Figure 2 shows that A-A cutaway view.Clearly illustrate the situation of runner in figure, because runner design can be comparatively random, compared with the mechanical governing system of complexity, fluid speed adjusting gear is relatively simple.Hydraulic Adjustable Speed can be used for accurate speed governing, and pneumatic speed governing has compressibility due to gas, can be used in the less demanding system of adjusting speed accuracy.In external hydraulic loop or pneumatic circuit, hydraulic control one-way valve or gas control unidirectional valve and electromagnetically operated valve etc. are as the switch controlling speed governing, the control of speed governing speed is then decided by the runner latus rectum of accurate Calculation, for pressurize, accumulator can be set in external circuit or integrated accumulator in center driving axle.
Fig. 3, Figure 4 shows that high speed rotary joint, adopt modular series connection structure, can to connect any passage, be two passages shown in Fig. 3, sealing ring 6-19,6-20 can select with the material such as tungsten carbide, graphite according to the situation of working fluid, and 6-5 is spring, are used for the wearing and tearing of equilibrium contact pressure and compensation sealing ring, the guide finger 6-7 at spring place plays guide and limit effect to spring, and when preventing high speed rotary, spring lost efficacy under centrifugal action.High speed rotary joint can be produced supporting by specialized factory, GT assembles, and is fixed on center driving axle by holding screw.
Figure 5 shows that piston rod and magnetic patch fixed disk assembly screw and baffle plate form a whole, then piston rod and center driving axle spline coupling, three's synchronous rotary.Spline is used for heavy duty, precision drive, can with dive key when low year, as shown in Figure 14.
Figure 6 shows that lever lazy-tongs.
Fig. 9, the inductive disks assembly that Figure 11 shows that series connection in the middle of serial fluid speed governing disc electromagnetic coupling (CFTLH series, CYTLI are serial) and magnetic patch fixed disk assembly, inductive disks assembly is positioned on the connection screw rod of magnetic coupling external rotor by positioning sleeve 8-1,8-2, and stop collar 8-3,8-4,8-5 to have slided position-limiting action to magnetic patch fixed disk assembly on center driving axle.In Figure 11, label 8-10 is intermediate transmission cover, itself and center driving axle spline coupling, and connects with semiaxis form with magnetic patch fixed disk assembly.
Figure 12, Figure 13 shows that inductive disks assembly, card is distributed with protruding blade, to help heat radiation.During unknown device rotation direction, shape shown in Figure 12 can be selected, as known device rotation direction, the streamline shape shown in Figure 13 can be selected, to increase heat dissipation capacity and to reduce flow-disturbing noise.Move equipment for underload, inductive disks assembly uses square position when can meet radiating requirements, shouldn't protruding blade, with simplified processing process.
Figure 14 shows that center driving axle adopts the scheme of dive key.
Figure 15 shows that the nested scheme of elongated hole in center driving axle.About the manufacturing process of elongated hole in center driving axle, directly Small and Deep Hole Machining can be carried out.For simplified processing process, reduce manufacturing cost, aluminium extruded type also can be adopted shaping, then carry out nested method with center driving axle.
Figure 16 shows that FTLH 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 assembly 1 and 5 forms external rotor by bolted on connection, magnetic patch fixed disk assembly 2 and 4 and speed adjusting gear 3, high speed rotary joint 6 connects to form internal rotor by center driving axle, inner and outer rotors is not in contact with each other, but owing to being difficult to the depth of parallelism ensureing inductive disks assembly and magnetic patch fixed disk assembly 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.
