Description

Transmission shaft permanent magnet coupling transmission and speed regulating device capable of adjusting magnetic torque

Technical field

The invention relates to the technical field of drive shaft coupling drive, the field of load speed regulation technology and the field of power drag, in particular to a transmission shaft permanent magnet coupling transmission and speed regulation device capable of adjusting magnetic torque.

Background technique

Around us, the fields involved in drive shaft coupling drive and speed regulation are everywhere, in various transportation vehicles such as automobiles, trains, ships and airplanes, in almost all industrial occasions, and in the production and life of people. Commonly used in the motor, internal combustion engine) dragging equipment, the transmission shaft coupling drive and speed control technology are used in the metropolis. The related technical solutions are also common. Since the field of application is very extensive and complicated, the background art of the present invention focuses only on the field of motor drag, but it does not mean that the technical solutions of the present invention are not applicable in other aspects.

At present, energy conservation and consumption reduction has become one of the key points of concern of the whole society, and the electricity consumption of the motor system accounts for about 60% of the global electricity consumption, and the electricity consumption of fans, pumps, compressors and air conditioners respectively account for 10.4%, 20.9%, 9.4% and 6% of global electricity consumption. The motor system is large in quantity and wide in area, and has great potential for saving electricity. Domestically, the existing installed capacity of various types of motor systems is about 420 million kilowatts, and the operating efficiency is 10-20 percentage points lower than the foreign advanced level, equivalent to about 150 billion kilowatt hours of wasted energy per year. The system matching is unreasonable. The phenomenon of “large horse-drawn car” is serious, and the equipment is running at low load for a long time. The system adjustment mode is backward. Most fans and pumps are regulated by mechanical throttling, and the efficiency is about 30% lower than the speed control mode. the above. In actual engineering design and application, in order to ensure that the fan or pump system meets the output requirements when the load is maximum, it is usually necessary to equip the fan pump system according to the maximum output capacity of the system. In practical use, in most cases, the system is not required to be fully loaded. Use below. Continuous control of flow and/or pressure can be achieved by adjusting the air gap, replacing the valve that controls the flow and/or pressure in the original system, and adjusting the speed of the fan or pump while the motor speed is constant, in accordance with the proportional law of the centrifugal load. . When the output flow and / or pressure is reduced, the motor power drops sharply, reducing energy requirements, thereby greatly saving energy. At present, the commonly used technologies in the field of motor drag have many shortcomings and shortcomings. With the development of permanent magnet coupling and speed control technology, it will gradually withdraw from the market or lose competitiveness in many application fields. For example: Cascade speed control technology can recover the slip power, but it is not suitable for squirrel cage type asynchronous motor, the motor must be replaced; soft start can not be realized, the starting process is very complicated; the starting current is large; the speed regulation range is limited; The response is slow, and it is difficult to achieve closed-loop control; the power factor and efficiency are low, and it drops sharply with the decrease of the rotational speed; it is difficult to achieve the same PLC, DCS The coordination of the control system is not beneficial to improve the overall automation of the device and to achieve optimal control. At the same time, because the control device is more complicated and the harmonic pollution has greater interference to the power grid, it further restricts its use, which is backward technology. The electromagnetic slip clutch speed control technology realizes the speed adjustment of the magnetic pole by controlling the excitation current of the electromagnetic clutch. This system generally also adopts the closed loop control of the speed. All the differential power of the speed control system is consumed, and the consumption of the differential power is increased in exchange for the decrease of the rotational speed, the slip rate is increased, the slip power is also increased, and the heat is consumed in the rotor circuit, so that The system efficiency also decreases. This kind of speed control system has the problem that the wider the speed regulation range, the larger the slip power, and the lower the system efficiency, the control device is also more complicated, so it is not worth promoting. The hydraulic coupling speed control technology is an inefficient speed regulation mode with limited speed range. The high speed drop is about 5%--10%, and the low speed slip loss is large, up to 30% of the rated power. Low precision, poor linearity, slow response, large starting current, large device, not suitable for transformation; easy to leak, complicated maintenance, high cost, can not meet the needs of improving the overall automation level of the device. The frequency conversion speed regulation technology is a relatively common and relatively advanced technology at present. The power electronic technology is used to realize the speed adjustment of the motor, which can be automatically controlled according to the actual working conditions to achieve a certain energy saving effect. However, the frequency conversion equipment is easy to generate harmonics. The high-power inverter has a very large harmonic pollution to the power grid. It is more expensive and more demanding on the environment. It requires an air-conditioning environment. In high-voltage environments, the failure rate is high, the safety is poor, and the frequency conversion is adjusted. The speed system requires professional maintenance, and the vulnerable parts often need to be replaced, the maintenance cost is high, and the speed regulation range is small, especially when the motor is damaged at low speed, and the corresponding frequency conversion motor is needed, for the commonly used high voltage of 6000V or higher. 50 kW --- For 10,000 kW models, the price is expensive and the total cost of ownership is very large.

Similarly, in other industries, there is a huge demand for drive shaft coupling drive and load speed control, and the requirements for its technological advancement are equally strong. It is urgent to replace new technologies with new technologies, such as those used in automobiles and machinery. The clutches, couplings, transmissions, etc., which are mostly hard-connected or friction-coupled transmission structures, have low efficiency, easy wear, poor reliability, are difficult to handle, difficult to manufacture and assemble, difficult to start equipment, and shaft pair Many shortcomings and shortcomings such as high quasi-demand, noise and vibration. Therefore, power transmission coupling, speed regulation and energy saving technology are a permanent research and development topic.

The permanent magnet coupling and speed control technology is the most advanced drive shaft coupling drive and speed control technology which is being further researched and developed. The main advantages are as follows: 1 energy saving, stepless adjustment of speed, speed range is 0-- -98%; 2 simple structure; 3 high reliability, easy to install, not afraid of harsh environment, Long life up to 25 More than 4 years; 4 soft start, power equipment is completely started under no load; 5 is not afraid of blocking, not afraid of pulse type load, mechanical seal; 6 tolerate shaft eccentricity, with load isolation, reduce vibration and noise; 7 extend equipment life, increase fault cycle, Reduce maintenance requirements; 8 no harmonic hazard, no damage to power equipment, does not affect grid safety, no power supply except actuator and controller, suitable for various industrial grade motor systems and explosion-proof occasions; 9 no electromagnetic interference; 10 The total cost of ownership is relatively low. Another important feature is that there are no requirements for the power source equipment, as long as the output shaft of the power source equipment rotates to work.

The permanent magnet coupling and governor seen on the market have been recognized and praised by users. For example, the related products of Magna Drive Company of the United States are also the only ones in the global market that are suitable for motor dragging. There are high-power models of permanent magnet coupling and governor products, and there are common transmission shaft double permanent magnet couplings or couplers that cannot be adjusted. Due to the limitations of their structural and technical solutions, the technical performance of their products has many deficiencies, which need to be improved and overcome. It mainly has the following shortcomings: 1 using only a single dual permanent magnet coupling component or an axial metal conductor. The magnetic coupling component, the technical advantage of permanent magnet coupling is not enough, so that the product structure is single, the power capacity per unit volume of the product can not be too large, and the transmission efficiency is also low; 2 the permanent magnet coupling and the governor itself cannot automatically adjust the air gap spacing To achieve the purpose of speed regulation, another actuator or device must be configured to achieve air gap spacing adjustment. It is a purely mechanical transmission shaft coupling and speed control transmission. In the context of the current advanced and reliable mechatronics technology, Non-mechatronic products can not meet the requirements of high reliability, high precision, timely follow-up and intelligent; 3 Due to the limitation of the working principle of permanent magnet coupling, the efficiency of permanent magnet coupling drive is low, the size of the magnetic coupling component Under the condition that the air gap spacing, the shaft speed and the speed difference are determined, the magnetic torque power per unit volume is also higher than that. Small and large heat generation, resulting in the design and manufacture of super-powered permanent magnet coupling and governor are also limited by cost and technical bottlenecks; 4 the heat dissipation technology on the heating parts of the product needs to be improved, and the heat dissipation technology is also to improve the permanent magnet coupling device. The technical bottleneck of transmission capacity per unit volume is an important technical guarantee for manufacturing larger power permanent magnet coupling and speed control devices. It is one of the technical support for long-term safe operation of super-high-power permanent magnet coupling and governor. According to the survey, currently Under the condition of 750 rpm, the air-cooled power can only be about 130 kW. Under the condition of 1500 rpm, the air-cooled power can only be about 300 kW, and its promotion and application are greatly limited. The main reason is related to the heat dissipation problem; the mechanical transmission mechanism used to adjust the air gap spacing in the product has inherent technical limitations and shortcomings, especially for two or more sets of magnetic coupling turntables or drums. Unit system, the transmission link has many mechanisms, the transmission gap between the mechanisms, the reliability is poor, the adjustment is not performed directly, the speed is slow, etc. The product can not be applied to the occasions with high requirements for speed regulation follow-up and speed regulation accuracy, such as the speed control occasion of large boiler feed water pump in power plant; 6 products do not have intelligent automation and intelligent control functions, let alone soft start And the humanized processing of abnormal load operation, can not be personalized parameter setting for different load characteristics and operating conditions, and is greatly limited in many applications; 7 due to a single product structure, it is limited in many application fields, currently only in Motor dragging field application; 8 product non-integrated machine packaging transportation structure, more complex components and components are installed at the product installation site, its structure and components are vulnerable to damage, damage, and sometimes installation accidents, endangering the human body Safety, installation quality is uneven, can not guarantee the quality and technical performance of the whole machine, it is necessary to design the structure of the product and its associated integrated assembly mechanism, and at the same time fundamentally solve the personal safety problems in the installation process, Avoid installation accidents.

There are currently four types of technical solutions for permanent magnet coupling torque transmission or drive technology. The first type is a dual permanent magnet coupling assembly of a conventional permanent magnet turntable coupled with a permanent magnet turntable. The second type is US Patent No. 5477094. A metal conductor permanent magnet coupling assembly formed by coupling a metal conductor turntable and a permanent magnet turntable, and a third type is an armature winding permanent magnet formed by coupling an armature winding disk and a permanent magnet turntable disclosed in the inventor's prior patent 200910148103.1 The coupling assembly, the fourth type is a pot-type armature permanent magnet coupling assembly and a squirrel-cage armature turntable and a radial direction, which are formed by coupling the pot-type armature turntable and the permanent magnet turntable disclosed in the inventor's prior patent 200910148102.7. The magnetic field permanent magnet turntable is coupled to form a squirrel-cage armature permanent magnet coupling assembly; each type of permanent magnet coupling assembly is further divided into two structural forms, one of which is a permanent magnet coupling component of an axial air gap magnetic field, The axial adjustment of the air gap spacing achieves the purpose of adjusting the magnetic torque to achieve the adjustment of the load rotation speed. One structural form is the inventor's prior patent 20091014810. The permanent magnet coupling assembly of the radial air gap magnetic field disclosed in 2.7 achieves the purpose of adjusting the load rotation speed by adjusting the coupling area of the air gap magnetic field to adjust the magnetic torque.

Based on the in-depth understanding of various permanent magnet coupling components in the long-term product application and R&D practice, it is necessary to carry out innovative integration and integration of the various permanent magnet coupling technical principles and related technical solutions, and complement each other. Combined with advanced design concepts, advanced permanent magnet coupling air gap spacing and air gap coupling area adjustment mechanism, and advanced sensor technology, automatic control and intelligent technology, to create an advanced, new, more convenient and safe installation, series The technical solution of the transmission shaft permanent magnet coupling transmission and speed regulation device with adjustable magnetic torque. According to the technical solution of the present invention, a series of products having different uses or different functions can be fabricated to perfect and overcome the above-mentioned shortcomings, defects and related technical bottlenecks of the permanent magnet coupling and governor products, and the permanent magnet coupling can be greatly improved. And the torque transmission or driving power provided by the unit volume of the governor product, and improve the magnetic torque transmission or driving efficiency, reduce the heat generation, and effectively solve the current existence of the permanent magnet coupling and governor products in the design and production process. In the context of various technical problems, the world is striving to save energy and reduce emissions and advocate scientific development. It is urgent to innovatively conceive and redesign the permanent magnet coupling torque transmission or driving mechanism and its technical solutions. High-power permanent magnet coupling and governor products provide important, core technical support and technical solutions to meet the advanced and cost-effective new drive shaft permanent magnet coupling drive and speed control products in the field of motor drive systems. urgent need.

As shown in Fig. 1, Fig. 2 and Fig. 3, it is a permanent magnet coupling device of a drum type structure composed of two inner drums (50, 51) and one outer drum (70). The end walls (80, 81) of the outer drum are respectively provided with axial magnetic field armature winding disks (1, 2), and the end walls (60, 61) of the inner rotating drum are respectively provided with axial magnetic field permanent magnet disks ( 35, 36), they respectively correspond to two axial magnetic field armature winding permanent magnet coupling assemblies (401, 402), and the inner circumferential surface (77) of the outer rotating cylinder wall (72) is provided with a radial magnetic field armature winding The outer circumferential surfaces (54, 55) of the discs (320, 321) and the inner rotating cylinder walls (52, 53) are provided with corresponding radial magnetic field permanent magnet disks (355, 356), and respectively coupled to form two radial directions. Magnetic field metal conductor permanent magnet coupling assembly (441, 442); air gap spacing and coupling area adjustment mechanism is a centrifugal adjustment mechanism, which is composed of a square center short shaft (125) and is disposed at the end wall of the inner drum (60, 61) a square shaft hole and its sleeve (135, 136), a spring centrifugal pin (172, 173) disposed on the inner circumferential surface (77) of the outer drum wall (72), and disposed at the square center short axis (125) consisting of the turntable limit pins (180, 181, 182) on the outside of the axial magnetic field armature winding discs (1, 2) The turret radiator (260, 261) is provided with a heat dissipation vent (264) on the outer end wall (82, 70); the outer cylinder wall (72) and the cage wall (280) are combined into one. The outer drum end wall (82, 70) and the cage end wall (284) are combined into one; the composite buffer delay spring (300, 301) is axially symmetrically disposed between the inner drum end walls (60, 61). The integrated assembly mechanism is provided by an integrated assembly screw hole and bolt between the turntables of the axial permanent magnet coupling assembly (315, 317) The composition is installed before the system is debugged after the factory is commissioned, and the task of the integrated assembly mechanism is completed after the equipment is removed one by one at the final stage of the equipment installation process. It does not affect the system structure and system functions, as shown in Figure 2. After removing the integrated assembly mechanism, the working principle and structural cutaway diagram of the working state in the unloaded state of the passive shaft blocking moment; the active permanent magnet coupling turntable coupling mechanism is composed of the outer rotating cylinder wall (72) or the cage wall ( 280), the outer drum end wall (82, 70) or the cage end wall (284), the outer drum end wall (82, 70 or 284) is coupled with the drive shaft coupling (310); passive permanent magnet The coupling turntable coupling mechanism is composed of an inner rotating cylinder end wall (60, 61), a square shaft shaft hole on the end wall (60, 61), a bushing (135, 136), a square center short shaft (125), and The turntable limit pin (180, 181, 182) is formed thereon, and the outer end of the square center short axis (125) is coupled with the adapted passive shaft coupling (311).

The working principle of the example: during the start of the drive shaft and driving the outer drum (70), the torque is generated between the turntables of the permanent magnet coupling assembly, the active turntable drives the passive turntable to rotate, and the passive turntable drives the square center short axis (125) Rotation; at the same time, the spring centrifugal pin (172, 173) speeds up from 0, and the centrifugal pin is in the pop-up state. At this time, due to the large difference in rotational speed between the rotary disks in the permanent magnet coupling assembly, the turntable will be Repulsive force is generated, and both inner drums (50, 51) push the inner rotating cylinder end wall (60, 61) under the action of the repulsive force between the rotating discs in the respective axial permanent magnet coupling assemblies (401, 402) The axial air gap spacing is increased, but is limited by the spring centrifugal pin (172, 173), forming an air gap spacing limited or automatic grading limit disengagement, with the continuation of the starting process, in the permanent magnet coupling assembly The difference in rotational speed between the turntables is gradually reduced, the repulsive force becomes attractive, and the two inner drums (50, 51) are pulled by the attraction between the turntables in the respective axial permanent magnet coupling assemblies (401, 402). Inner drum end wall (60, 61) The axial air gap spacing becomes smaller, and the limit of the limit pin (180, 182) or the set air gap distance is always running at the set speed. At this time, the spring centrifugal pin (172, 173) has a large rotation speed. The centrifugal pin is in a non-restricted state, and a composite buffering delay spring (300, 301) made of a compression spring and a tension spring between the end wall (60, 61) of the inner drum can also delay the air gap spacing. Adjusting the speed to achieve the purpose of slow soft start; as shown in Fig. 2, when the passive shaft is blocked, the difference in rotational speed between the rotary discs in the axial permanent magnet coupling assembly is rapidly maximized, and the axial permanent magnet coupling assembly (401) The attraction between the turntables in 402) quickly becomes a repulsive force, pushing the end wall (60, 61) of the inner drum to slide on the short center axis (125) of the square, which promotes the axial air gap spacing and is free from the spring centrifugal pin. (172, 173) the limit is reached to the maximum, for the purpose of rapid or emergency unloading; when the subsequent stall phenomenon disappears, because the active axial magnetic field armature winding disc (1, 2) keeps rotating at a constant speed, the repulsive force will Gradually become attractive, the system will automatically a soft start process to achieve the purpose of allowing for stalling or tolerating the pulse load; in addition, the radial repulsive force or radial attractive force generated by the radial permanent magnet coupling assembly (441, 442) during start-up and stalling The magnetic torque force is perpendicular to the axial thrust and tensile force acting on the inner end wall (60, 61) of the inner drum and they themselves act symmetrically opposite to each other in the axial direction without affecting the air gap adjustment process. The natural air-cooled turntable radiators (260, 261) are arranged for heat dissipation processing of the axial magnetic field armature winding disks (1, 2) to ensure that the system can work normally; it should be noted that this embodiment also includes implementation In the example, the active shaft and the passive shaft are used in reverse or interchangeably, and the inverted or interchanged transmitting device can work normally, which is applicable to all the technical solutions and embodiments of the present invention.

In this case, only the simplest square center stub is used as an example.
