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, has occurred panoramic product.Cartridge type magnetic coupling is as the type in Ci Ou family, because of the reason of its configuration aspects, slightly inferior in safety in utilization, reliability etc., but in some local domain, cartridge type magnetic coupling is also a kind of good transmission device, has its distinctive feature.
Energy-saving and emission-reduction are current active demands, and generally apply fluid-flywheel clutch at present and carry out power transmission, transmission efficiency is lower relative to magnetic coupling.Although frequency control is more or less the same with magnetic coupling on speed efficiency, the useful life of frequency converter greatly differs from each other compared with magnetic coupling with maintainability.
Summary of the invention
The present invention focuses on the technical method finding the speed governing of a kind of cartridge type magnetic coupling, four large serial TG type (abbreviation of cartridge type G type) the ball-screw electric speed regulation cartridge type magnetic couplings of extending out along with this technical method: air-cooled TGA type ball-screw electric speed regulation cartridge type magnetic coupling (TFTGA series), liquid cooling TGA type ball-screw electric speed regulation cartridge type magnetic coupling (TYTGA series), air-cooled TGB type ball-screw electric speed regulation cartridge type magnetic coupling (TFTGB series), liquid cooling TGB type ball-screw electric speed regulation cartridge type magnetic coupling (TYTGB series).
TGA type and TGB type are distinguished and are that the position that governing system connects is different, and TGA type is internal rotor, and TGB type is external rotor, and its speed control system structure is the same with principle.
Accompanying drawing explanation
Fig. 1 is air-cooled TGA type ball-screw electric speed regulation cartridge type magnetic coupling (TFTGA series), Fig. 7 is liquid cooling TGA type ball-screw electric speed regulation cartridge type magnetic coupling (TYTGA series), Fig. 5 is air-cooled TGB type ball-screw electric speed regulation cartridge type magnetic coupling (TFTGB series), and Fig. 9 is liquid cooling TGB type ball-screw electric speed regulation cartridge type magnetic coupling (TYTGB series).
Four large serial TG type ball-screw electric speed regulation cartridge type magnetic couplings, all comprise following several part: induction cylinder 2, magnetic patch stationary magazine creel 3, magnetic patch 4, cover plate 5, shielding cylinder 1, center driving axle 11, flange shaft sleeve 27, leading screw 22, feed screw nut 23, main central gear 19, sectional center gear 21, planetary gear 20, planet stent 15, main support 16, bearing 14 and 8 etc.In liquid-cooling type, number in the figure 40 is right cover plate, and 43 is left cover, and 41 and 44 is sealing ring, and 42 is housing.
In four large serial TG type ball-screw electric speed regulation cartridge type magnetic couplings, magnetic patch stationary magazine creel 3, magnetic patch 4, cover plate 5, center driving axle 11 equijoin composition internal rotor, induction cylinder 2, shielding cylinder 1, flange shaft sleeve 27 equijoin composition external rotor, ball-screw (leading screw 22, the compositions such as feed screw nut 23 and steel ball) and planet circular system (main central gear 19, sectional center gear 21, planetary gear 20, the compositions such as planet stent 15 and main support 16) form speed adjusting gear, this speed adjusting gear and speed governing driven wheel, clutch, speed governing drive motors etc. is combined to form governing system.Ball-screw in speed adjusting gear adopts single group.The center driving axle of center driving axle 11, flange shaft sleeve 27 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 rotor, ball-screw planet circular system speed adjusting gear 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 the rotation of main central gear 19, due to the effect of differential, sectional center gear 21 starts rotation, thus drive leading screw 22 rotation, screw turns, feed screw nut 23 moves vertically, thus the coupling area changed between induction cylinder and magnetic patch stationary magazine creel, to reach the object (change of magnetic Field Coupling area 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).

Figure 10 is the speed governing drive scheme schematic diagram of liquid cooling TGB type ball-screw electric speed regulation cartridge type magnetic coupling (TYTGB series).
In Figure 4 shows that TFTGA series magnetic coupling takes off, the structural representation of positioning support bearing between external rotor, between power transmission shaft, connection adopts expansion set, other series (TYTGA series, TFTGB series, TYTGB series) also can do like this, but this scheme only can be used on low year situation and axle alters very small situation, reason is as follows: inner and outer rotors is not in contact with each other, but owing to being difficult to ensure the axiality between induction cylinder and magnetic patch stationary magazine creel 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.
