Description

524 type grooved cam electric speed regulation disc type magnetic coupler

Technical field

Power transmission, energy-saving and emission-reduction, dynamic equipment, magnetically-actuated.

Background technology

From the beginning of human use ground Magnetic driving invention compass, the research on utilization of magnetic field energy just never stopped.Along with now For the development of theory of magnetism, the application in the industry of magnetically-actuated product just emerges in an endless stream, magnetic drive pump, magnetic bearing, magnetic force coupling Clutch, magnetic-gear etc..Being limited to the restriction of magnetic material, Drive Technology slower development, until nineteen eighty-three, middle promulgated by the State Council Understanding high performance permanent magnetic materials neodymium iron boron, magnetically-actuated product is just rapidly developed application.

Magnetic coupling since the development of independent conduct single branch, has occurred in that shape shape from magnetic drive pump isodynamic driving product The product of look look, but the reason that be all confined to configuration aspects, can only be confined to the interval dynamic equipment of middle low power, medium and small moment of torsion and move In power transmission application, and expensive.As the primary air fan (6000KW, 1496r/min) of thermal power plant, overfire air fan (4550KW, 1495r/min), the dynamic equipment such as the large fan of coal breaker (1200KW, 490r/min) and steel mill, mining site, 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 machine at present more efficiently Structure speed governing magnetic coupling variable speed energy saving.Frequency converter is shorter for service life, adaptive capacity to environment difference, takes up an area space greatly, safeguards and need Asking high, high voltage converter fault rate is then higher, poor reliability.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 then 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 not high.

Content of the invention

The present invention focuses on the technical method finding a kind of disc electromagnetic coupling speed governing, two big series of extending out along with this technical method The air-cooled 524 type grooved cam electric speed regulation disc type magnetic coupler of 524 type grooved cam electric speed regulation disc type magnetic coupler (FT524 series), the cold 524 type grooved cam electric speed regulation disc type magnetic coupler of liquid (YT524 series).

Brief description

Fig. 1 is air-cooled 524 type grooved cam electric speed regulation disc type magnetic coupler (FT524 series), the cold 524 type ditch geosynclinal convexs of liquid Wheel electric speed regulation disc type magnetic coupler (YT524 series) installs shell additional, and coolant is by pipeline turnover, forced fluid on shell Cold.

524 type grooved cam electric speed regulation disc type magnetic coupler, all comprise following several part: in figure, label 1 and 5 is sensing Dish assembly, 2 and 4 is magnetic patch fixed disk assembly, and 3 is grooved cam speed adjusting gear, and 6 is (or electronic at a high speed revolution conductive contact Speed governing specialized high-speed swivel coupling), 7 is motor stator, and 8 is rotor, power transmission shaft centered on 11, and 19 is support, 23 For flange shaft sleeve.

In two serial greatly 524 type grooved cam electric speed regulation disc type magnetic coupler, grooved cam speed adjusting gear 3 and external rotor electric Machine forms external rotor electric machine external grooved cam speed adjusting gear, and all of inductive disks assembly is formed outer rotor by caging bolt connection, All of magnetic patch fixed disk component string is associated on center driving axle, forms together with external rotor electric machine external grooved cam speed adjusting gear Internal rotor.Turn round at a high speed slip ring and the rotor synchronous axial system of conductive contact, geo-stationary, turn round at a high speed the electricity of conductive contact Brush and support keep geo-stationary.The brush of revolution conductive contact connects external power source at a high speed.Two-way switch control enters motor The sense of current, thus change motor outer rotor and turn to the relative of center driving axle.Motor outer rotor drives grooved cam assembly, Make rotation motion be in line slip, drive magnetic patch fixed disk assembly to slide along center driving axle, thus change magnetic patch fixed disk group Distance (magnetic field coupling gap) between part and inductive disks assembly, with reach variable speed energy saving purpose (change of magnetic field coupling gap, The change of magnetic coupling inner and outer rotors slip, the namely change of input and output rotating speed will be caused).

Fig. 2 show A-A section view, has clearly given expression to the position of three synchronizing bars.

Fig. 3 show magnetic patch fixed disk assembly 2, has clearly given expression to powerdriven mode semiaxis, also show magnetic patch Distribution situation.

Fig. 4 show magnetic patch fixed disk assembly 4, and it can not directly and center driving axle 11 carries out power transmission, Dan Keyan center Power transmission shaft 11 slides, and magnetic patch fixed disk assembly 4 relies on three synchronizing bar 3-3 to carry out driving coupling, also show magnetic patch Distribution situation.

Fig. 5 is grooved cam speed adjusting gear, and spacing back-up ring 3-1 is used for ensureing that synchronizing bar 3-3 will not occur axial float, and 3-2 is Fine setting spring, 3-4 is grooved cam, and 3-5 is that roller fixes axle, and 3-8 is synchronizing bar retainer.

Fig. 6 show revolution conductive contact at a high speed, uses modular construction, and the quantity of slip ring determines as required, shown in figure Being three slip rings (can be six or arbitrarily individual), connecting three of the wires, middle ring 6-2, overcoat 6-7, overcoat 6-1 adopt With electrically insulating material, 6-5 is brush, and 6-4 is slip ring (being embedded in overcoat 6-1), and 6-8 (is used for putting down for fine setting spring Weighing apparatus contact), 6-3 is wire, and 6-9 is bearing.Slip ring, external external power source is connect in brush.Slip ring 6-4 is embedded in anti- It inside sheath 6-1, is fixed on rotor 8.Brush 6-5 is assemblied in insulating materials inside and keeps geo-stationary with support, Rely on the impact of bearing 6-9 isolation rotor 8 High Rotation Speed.At a high speed revolution conductive contact is using brush and slip ring as dynamically connecing Touch, it is also possible to fill counter to brush and slip ring, by connecing brush in slip ring, external external power source.

Fig. 7, Fig. 8 show inductive disks, protruding blade are distributed, to help heat radiation in card.During unknown device rotation direction, can be selected for Shape shown in Fig. 7, such as known device rotation direction, can be selected for the streamline shape shown in Fig. 8, to increase heat dissipation capacity and to reduce flow-disturbing and make an uproar Sound.When heat dissipation capacity is enough, inductive disks uses square position, removes protruding blade, to simplify manufacturing process.

Fig. 9 show the structural representation that FT524 series magnetic coupling takes off internal two supports bearing, couples employing swollen between power transmission shaft Set, other series also can do so, but this scheme only can be used on low load situation and axle alters very small situation, and reason is as follows: Inductive disks assembly 1 and 5 is formed outer rotor by bolted on connection, and magnetic patch fixed disk assembly 2 and 4 is with grooved cam speed adjusting gear the 3rd, Motor stator the 7th, rotors 8 etc. are connected by center driving axle and form internal rotor, and inner and outer rotors is not in contact with each other, but due to assembling When it is difficult to ensure that the depth of parallelism of inductive disks assembly and magnetic patch fixed disk assembly, so can be at motor center axle bearing supporting and load Alternate stress (effect of magnetic field coupling additional bending moment) is caused, so that axle excessive wear was lost efficacy at transmission shaft bearing supporting.Additionally, The impact that axle is altered can cause bumpy running, can cause the accident when serious.Generally speaking, this kind of scheme to be cautious use of.
