Abstract

The invention relates to a P-type ball screw electric speed regulation disc 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 regulating system which is composed of a single group of ball screws, a planetary gear system, a clutch and a speed regulation driving motor. The P-type ball screw electric speed regulation disk type magnetic coupler is divided into two series, namely, an air cooling P-type ball screw electric speed regulation disk type magnetic coupler (FTP series) and a liquid cooling P-type ball screw electric speed regulation disk type magnetic coupler (YTP series). The P-type ball screw electric speed regulation disk type magnetic coupler finds an economically feasible method for speed regulation and energy conservation of dynamic equipment.

Description

P-type ball-screw 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 the most never stopped.Along with existing 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.
Summary of the invention
The present invention focuses on the technical method finding a kind of disc electromagnetic coupling speed governing, the two big Series P of extending out along with this technical method Type ball-screw electric speed regulation disc type magnetic coupler air-cooled p-type ball-screw electric speed regulation disc electromagnetic coupling (FTP series), Liquid cold p-type ball-screw electric speed regulation disc electromagnetic coupling (YTP series).
Accompanying drawing explanation
Fig. 1 is air-cooled p-type ball-screw electric speed regulation disc electromagnetic coupling (FTP series), liquid cold p-type ball-screw electric speed regulation dish Formula magnetic coupling (YTP series) adds casing, and coolant is passed in and out by pipeline on shell, and forced fluid is cold, and the speed governing of speed governing drives Gear is assemblied in enclosure interior.
P-type ball-screw electric speed regulation disc electromagnetic coupling, all comprises following several part: in figure, label 1 and 5 is inductive disks, 2 Hes 4 is magnetic piece fixed disk, and 3 is ball-screw planet circular system combined speed regulating mechanism, and 6 is interior center driving axle, and 9 is outer center driving Axle.
In two big Series P-type ball-screw electric speed regulation disc electromagnetic couplings, inductive disks 1 and 5 is passed with outer center by caging bolt connection Moving axis 9 forms outer rotor, and magnetic piece fixed disk 2 and 4 is connected on interior center driving axle 6, and the combination of ball-screw planet circular system Speed adjusting gear 3 forms internal rotor together.Interior center driving axle 6, outer center driving axle 9 and load and the center driving of prime mover Axle couples use key connecting, it is possible to use expansion set connection.
During the work of magnetic coupling, magnetic coupling internal rotor, ball-screw planet circular system combined speed regulating mechanism and speed governing drive gear synchronous high-speed rotary Turning, when speed governing, clutch engages, and speed governing drives driven by motor to adjust speed drive gear rotation, and speed governing drives in gear driven master Heart gear 3-14 rotation, due to the effect of differential, sectional center gear 3-12 starts rotation, thus drives leading screw 3-5 rotation, Screw turns, feed screw nut 3-4 is axially moveable, thus (magnetic field couples to change the distance between magnetic piece fixed disk and inductive disks Gap), to reach the purpose of variable speed energy saving, (change of magnetic field coupling gap will cause the change of magnetic coupling inner and outer rotors slip, also It is exactly the change of input and output rotating speed).
Fig. 2 is A-A sectional view.
Fig. 3 show ball-screw planet circular system combined speed regulating mechanism, and spacing back-up ring 3-1 is used for ensureing that synchronizing bar 3-3 will not send out Raw axial float, 3-2 is fine setting spring, and 3-4 is feed screw nut, and 3-5 is leading screw, and 3-8 is synchronizing bar retainer.3-14 is Main central gear, 3-12 be sectional center gear, 3-13 be planetary gear, 3-26 be planet stent, 3-19 be main support, 3-17,3-23,3-7 are bearing.
Fig. 4 show magnetic piece fixed disk 2, has clearly given expression to powerdriven mode semiaxis, also show dividing of magnetic piece Cloth situation.
Fig. 5 show magnetic piece fixed disk 4, and it can not carry out power transmission by direct and interior center driving axle 6, but can slide axially, Magnetic piece fixed disk 4 relies on three synchronizing bar 3-3 to carry out driving coupling, also show the distribution situation of magnetic piece.
Fig. 6 is the speed governing drive scheme schematic diagram of air-cooled p-type ball-screw electric speed regulation disc electromagnetic coupling (FTP series).
Fig. 7 show FTP series 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 1 and 5 is formed outer rotor by caging bolt connection with outer center driving axle 9, and magnetic piece fixed disk 2 and 4 is connected on interior center and passes On moving axis 6, forming internal rotor together with ball-screw planet circular system combined speed regulating mechanism 3, inner and outer rotors is not in contact with each other, but by It is difficult to ensure that the depth of parallelism of inductive disks and magnetic piece fixed disk when assembling, so can pass with load at motor center axle bearing supporting Alternate stress (effect of magnetic field coupling additional bending moment) is caused, so that axle excessive wear was lost efficacy at moving axis bearing supporting.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.
