Technical field

The utility model relates to that motor drags, load governing system field, particularly a kind of permanent magnet coupling device for cylindrical transmission shaft.

Background technology

At present, the energy-saving and cost-reducing emphasis of whole society's concern and the target of scientific development of having become.The electric system power consumption accounts for 60% of global power consumption, and wherein the power consumption of blower fan, pump class, compressor and air conditioner refrigerating device accounts for 10.4%, 20.9%, 9.4% and 6% of global power consumption respectively.The electric system amount is big, wide, and energy conservation potential is huge.From domestic, about 4.2 hundred million kilowatts of existing all kinds of electric system total installations of generating capacity, operational efficiency are equivalent to about 1,500 hundred million kilowatt hours of annual waste electric energy than low 10---20 percentage point of external advanced level.Motor and low by driven equipment efficient, the outmoded backwardnesss of equipment such as motor, blower fan, pump, efficient is than low 2---5 percentage point of external advanced level; System matches is unreasonable, and " low load with strong power " phenomenon is serious, the long-term underrun of equipment; System's regulative mode falls behind, and most of blower fan, pump class adopt mechanical throttle style to regulate, and efficient is lower approximately more than 30% than mode of speed regulation.

In actual engineering design and in using, blower fan or water pump system satisfy the output requirement in order to guarantee to load maximum, usually need to be equipped with the blower fan water pump system, and in the real practicality, be not to need system under full load, to use in most cases by the maximum fan-out capability of system.Can realize the continuous control of flow and/or pressure by regulating air gap, replace the valve of control flow in the original system and/or pressure, under the constant situation of motor speed, regulate the rotating speed of blower fan or water pump, meet the proportionality law of centrifugal load.When output flow and/or pressure minimizing, power of motor sharply descends, and has reduced energy demand, thereby has saved the energy widely.Therefore, in the motor driving system field, power transmission coupling, speed governing and power-saving technology are permanent research and development problems.

The state of the art of present several traditional modes of speed regulation of using always:

The tandem control technology can reclaim slip power, but it is not suitable for the mouse-cage type asynchronous machine, must change motor; Can not realize soft start, start-up course is very complicated; Starting current is big; Speed adjustable range is limited; Low-response is difficult for realizing closed-loop control; Power factor and efficient are low, and with the rapid decline of turning down of rotating speed; Be difficult to realize the cooperation of same PLC, DCS dispatch control system, unhelpful to the integrated automation degree and the realization optimal control that improve device; Greatly electrical network is disturbed because of control device more complicated, harmonic pollution simultaneously; Further limit its use, belonged to backward technology.Electromagnetism slip destage device speed adjusting technique, by the control of electromagnetic clutch exciting current being realized the speed regulation to its magnetic pole, this system generally also adopts speed closed loop control.The whole slip powers of this governing system all are consumed, exchange the reduction of rotating speed for the consumption that increases slip power, revolutional slip increases, and slip power also increases, and consumes in rotor circuit with the heating form, make system effectiveness also decrease, it is wideer that this class governing system exists speed adjustable range, and slip power is bigger, the system effectiveness low problem that heals, the control device that matches is also comparatively complicated, so be unworthy advocating.

The fluid coupling speed adjusting technique belongs to the poor efficiency mode of speed regulation, and speed adjustable range is limited, and about 5%---10% throws switch at a high speed, the low speed slip loss is big, reaches as high as more than 30% of rated power, and precision is low, poor linearity, low-response, starting current is big, and device is big, is not suitable for transforming; Easily leakage, safeguard complicated, expense is big, can not satisfy the needs that improve device integrated automation level.

Variable-frequency control technique is to use commonplace and relative advanced technology at present, adopts power electronic technology to realize the speed of motor is regulated, and can effectively control automatically according to actual condition, can realize certain energy-saving effect.But frequency conversion equipment easily produces harmonic wave, and big-power transducer is very big to the harmonic pollution of electrical network; It requires also to compare " enervated " to space environment, needs air conditioner surroundings; Failure rate height under the hyperbaric environment, poor stability, frequency conversion speed-adjusting system needs the professional to safeguard, and damageable spare parts needs to change the maintenance cost height often, speed adjustable range is little, particularly big to motor infringement when its low cruise, need to be equipped with corresponding variable-frequency motor, for the above high pressure of 6000V commonly used and 50 kilowatts--the frequency converter of-10000 kilowatts of models, it costs an arm and a leg, and owner's total cost is very big.

Permanent magnetism coupling and speed adjusting technique, permanent magnetism coupling torque transfer or driving and speed governing are that the most advanced, that further research and develop energetically at present motor drags and speed adjusting technique.Major advantage shows: 1. energy-conservation, can stepless adjustment rotating speed, and speed adjustable range is at 0---98%; 2. simple in structure; 3. the reliability height is installed easily, is not afraid of adverse circumstances, and the life-span reached more than 25 years; 4. soft start, motor starts under zero load fully, significantly reduces starting current; 5. be not afraid of stall, be not afraid of the impulse type load, protection motor, mechanical seal; 6. tolerate eccentric shaft, have load isolation, lower vibration, noise; 7. prolong equipment life, increase inaction interval, reduce maintenance needs; 8. do not have harmonic wave harm, do not injure motor, do not influence power grid security; 9. there is not Electromagnetic Interference; 10. owner's total cost is lower.

Known permanent magnetism coupling torque transfer or drive mechanism are, referring to United States Patent (USP) NO.5477094, conductor rotor dish and p-m rotor dish have relative motion, when the conductor rotor dish rotates cutting magnetic line in the alternating magnetic field that the p-m rotor dish produces, can form inductive loop, this eddy current produces reverse induction magnetic field conversely, the magnetic field interaction that this induced field and p-m rotor dish produce, make and produce the magnetic moment of torsion between conductor rotor dish and the permanent magnet rotor dish, stop the relative motion of conductor rotor dish and p-m rotor dish, just made up the drive mechanism of a magnetic moment of torsion like this between conductor rotor dish and the p-m rotor dish, a rotor disk drives another rotor disk and rotates in the same way, and then the drive load rotates.According to this working mechanism, permanent magnetism coupling torque transfer or drive unit are set between the motor shaft bearing axle corresponding with it, on motor (or load) axle copper conductor rotor disk is set, correspondence is provided with the p-m rotor dish on load (or motor) axle, because during the motor rotation, drive copper conductor rotor disk cutting magnetic line in the high-intensity magnetic field that the p-m rotor dish is produced, thereby in the copper conductor rotor disk, produce eddy current, this eddy current produces dislike magnetic field conversely around the copper conductor rotor disk, stop the relative motion of copper conductor rotor disk and p-m rotor dish, thereby realized torque transfer or driving between motor and the load.All manufacture and design about permanent magnetism coupling torque transfer or driving and speed regulator product in the market according to this working mechanism and technical scheme, relevant series of products of U.S. Magnadrive Corp. for example, also be a kind of permanent magnetism coupling and speed regulator product up-to-date release, unique on the present world market, be subjected to the approval and the welcome in market; But, owing to its permanent magnetism coupling torque transfer or the mechanism of driving and the reason of conductor rotor dish configuration aspects, under the equal conditions that size, air-gap separation, axle rotating speed and the speed discrepancy of conductor rotor dish and p-m rotor dish are determined, the magnetic torque through-put power that unit volume can provide is also smaller, permanent magnetism coupling torque transfer or drive that efficient is also lower, caloric value is bigger causes the permanent magnetism coupling and the manufacturing and designing of speed regulating device of super high power to be subjected to cost and technology limitation.Because a large amount of heat radiations on the metal conductor plate, cause the radiator that complicated large volume must be set thereon, in order to improve the unit volume through-put power capacity of permanent magnetism coupling torque transfer or drive unit, relevant heat dissipation technology has also become design to produce a technical bottleneck of permanent magnetism coupling series of products.According to investigations, adopt the permanent magnetism coupling or the speed regulator product of present known solution, under 750 rev/mins of conditions, the power maximum of coupling of Wind-cooling type permanent magnetism or speed regulator can only be accomplished about 130 kilowatts, under 1500 rev/mins of conditions, the power maximum of coupling of Wind-cooling type permanent magnetism or speed regulator can only accomplish that about 300 kilowatts, it is applied and is greatly limited.

The utility model has made up a kind of novel power transmission shaft permanent magnetism coupling torque transfer mechanism and novel power transmission shaft permanent magnetism coupling electromagnetic torque transmission structure thereof, proposed to regulate the new method of transfer of torque or regulating load speed, and merge multinomial suitable advanced technology and design concept, designed a kind of brand-new permanent magnet coupling device for cylindrical transmission shaft, to improve and to overcome the above-mentioned deficiency of present permanent magnetism coupling and speed regulator product, the restriction of defective and correlation technique bottleneck, can improve permanent magnetism is coupled and the unit volume of speed regulator product can provide torque transfer or driving power greatly, and improve the magnetic torque transfer greatly or drive efficient, reduce caloric value, effectively solve many-sided technical problem that present permanent magnetism coupling and speed regulator product exist in design and production process, more advanced for designing, more powerful permanent magnetism coupling and speed regulator product provide important, the technical support of core and technical scheme; All making great efforts energy-saving and emission-reduction, advocating under the background of scientific development in the whole world, an urgent demand is conceived permanent magnetism coupling torque transfer or drive mechanism and technical scheme thereof with reforming and is redesigned, to address the above problem, adapt to the motor driving system field to advanced person's the power coupled transfer and the urgent need of speed adjusting technique.
