Abstract
The invention relates to an S-type ball screw electric speed regulation disk type magnetic coupler which can be incorporated into the fields of power transmission, energy conservation and emission reduction, dynamic equipment and magnetic driving. The disk type magnetic coupler utilizes a speed regulation system which is composed of an inner-rotor motor ball screw speed regulation mechanism and a high-speed rotating conductive joint. The S-type ball screw electric speed regulation disk type magnetic coupler is divided into four series, namely, an air cooling S-type ball screw electric speed regulation disk type magnetic coupler (FTS), a liquid cooling S-type ball screw electric speed regulation disk type magnetic coupler (YTS), a cascade air cooling S-type ball screw electric speed regulation disk type magnetic coupler (CFTS), and a cascade liquid cooling S-type ball screw electric speed regulation disk type magnetic coupler (CYTS). The S-type ball screw electric speed regulation disk type magnetic coupler finds an economically feasible method for speed regulation and energy conservation of dynamic equipment.

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 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.

Turning round at a high speed the carbon brush (with center driving axle geo-stationary) of conductive contact, the slip ring of revolution conductive contact connects external power source at a high speed.
Two-way switch controls to enter the sense of current of motor, thus changes motor steering.Motor internal rotor drives screw turns, and leading screw turns
Dynamic, feed screw nut (being fixed together with magnetic piece fixed disk) is axially moveable, thus changes between magnetic piece fixed disk and inductive disks
Distance (magnetic field coupling gap), to reach the purpose of variable speed energy saving, (change of magnetic field coupling gap will cause that magnetic coupling is inside and outside to be turned
The change of sub-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.
