Description
Technical field
The present invention relates to a kind of permanent-magnet speed governor, be specifically related to the permanent-magnet speed governor of a kind of fixing magnetic gap.
Background technology
Permanent-magnet speed governor is the magnetic couple speed governing by permanent magnet, soft (magnetic) that realizes motor and load connects, have no effect electrical network harmonic wave produce, reliability is high, and can work under the various adverse circumstances such as high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and thunder and lightning, significantly alleviate mechanical vibration, be widely used in electric power, iron and steel, metallurgy, petrochemical industry, papermaking, municipal administration, naval vessel, irrigate and the industry such as mining.And permanent-magnet speed governor conventional at present all realizes adjustment of rotational speed by adjusting air gap, the power consumption of magnetic circuit actuator is big, and has that torque-transfer capability is poor, assembly difficulty height, wastes the shortcomings such as a large amount of rare earth resources.In addition producing relative motion with p-m rotor when conductor rotor rotates, permanent magnetic field produces eddy current in conductor rotor, produces amount of heat therewith, and owing to conductor rotor and p-m rotor must exist slippage, speed adjustable range is 0 to 98%.
Summary of the invention
For the problems referred to above, the present invention provides the permanent-magnet speed governor of a kind of a kind of fixing magnetic gap reducing magnetic circuit actuator power consumption, raising torque-transfer capability, reduction assembly difficulty, saving rare earth resources, reduction heat generation, increase speed adjustable range.
Current permanent-magnet speed governor be all the air gap by changing between conductor rotor and p-m rotor thus control conductor rotor cutting magnetic line number, realize what torque adjusted, owing to this mode exists a lot of drawback, the present invention is based on the attracting principle of magnet homopolar-repulsion, heteropole, start with from the active force changed between magnet rotor and interior magnet rotor and design new permanent-magnet speed governor, thus reach to change the purpose of torque.
For solving the problems referred to above, the technical scheme that the present invention takes is: the permanent-magnet speed governor of a kind of fixing magnetic gap, including the outer magnet rotor being connected with driving shaft and through driven shaft concentric pass first in magnet rotor in magnet rotor and second, described outer magnet rotor is evenly distributed with the outer permanent magnet of at least two along its inner peripheral surface circumference, each outer permanent magnet pole is circumferentially arranged, and the sides adjacent magnetic pole magnetic of adjacent two outer permanent magnets is different；Permanent magnet in permanent magnet and second in magnet rotor is all evenly distributed with at least two first along respective outer circumference surface circumference in magnet rotor and second in described first, in each, permanent magnet pole is circumferentially arranged, and the sides adjacent magnetic pole magnetic of permanent magnet is different in adjacent two on same interior magnet rotor, in first, in permanent magnet and second, the magnetic pole end face side of permanent magnet is respectively equipped with the first iron yoke and the second iron yoke, and in two, the interior permanent magnet quantity on magnet rotor is identical；It is provided with on magnet rotor in first and drives the magnetic circuit actuator that in first, magnet rotor magnet rotor in second rotates, the position relationship of interior permanent magnet magnetic pole of the same name on magnet rotor in regulation two.Described magnetic circuit actuator position relationship of permanent magnet magnetic pole of the same name in permanent magnet and second in regulation first, and then change magnet rotor in outer magnet rotor and first, active force between magnet rotor in second.Specifically regulate process: by magnet rotor in magnetic circuit actuator rotation first, when the magnetic pole of the same name of the second permanent magnet and the first permanent magnet is in corresponding position, first iron yoke, the second iron yoke are all magnetized to the kicker magnet of corresponding polarity, externally display magnetic is the strongest, maximum captivation or repulsive force is produced according to the attracting principle of homopolar-repulsion heteropole, so that inside and outside magnet rotor is in the same direction or adverse movement realize strength transmission with outer magnet rotor；On the contrary, when the synonyms pole of the second permanent magnet and the first permanent magnet is in corresponding position, the magnetic line of force passes through smoothly through the first iron yoke, the second iron yoke, internal short-circuit, and the first iron yoke, the second iron yoke the most do not show magnetic；Outer permanent magnet does not produce active force to first, second iron yoke, and inside and outside magnet rotor cannot realize strength transmission.
In first, in permanent magnet and second, permanent magnet is turned to the corresponding process of the position of magnetic pole of the same name process that to be exactly two interior magnet rotors change from small to big with the intermolecular forces of outer magnet rotor by synonyms pole position is corresponding, thus realize transmitting the change of strength, it is achieved in speed-regulating function.Generally driving shaft connects mair motor, and driven shaft connects load, but both can exchange, i.e. driving shaft connects load, and driven shaft connects mair motor.
This kind of mode, for changing the conductor rotor axial distance with p-m rotor, reduces the power consumption of magnetic circuit actuator, reduces heat and produces, improves the transmission capacity of moment of torsion.
Outer permanent magnet quantity on outer magnet rotor is identical with permanent magnet quantity in first on magnet rotor in first.In first magnet rotor, time magnet rotor is equal with outer magnet rotor permanent magnet quantity in second, it is possible to achieve input, the speed-regulating function of output speed 0 ~ 100%.
Outer permanent magnet quantity on outer magnet rotor is different from permanent magnet quantity in first on magnet rotor in first, but in first on magnet rotor first in permanent magnet and second on magnet rotor second in permanent magnet quantity identical time, can realize input, output speed 0 ~ N% speed-regulating function (can raising speed or reduction of speed, moment of torsion with N inverse proportion change, peak power constant).
Described magnetic circuit actuator includes the adjusting actuator for receiving control signal.
Described adjusting actuator can be electric operator, pneumatic actuator or hydraulic actuating mechanism.During use, permanent-magnet speed governor is installed in certain control system, pressure, flow, liquid level or other control signals are received by control system and process, it is then provided to adjusting actuator, controlled the rotation of magnet rotor in first by the actuator of adjusting actuator, change the first iron yoke, the second iron yoke externally shows the size of magnetic.
Due to the fact that and have employed fixing magnetic gap structure, substantially increase the area of contact of speed regulator and reduce assembly difficulty, reduce heat and produce, increase speed adjustable range, saved rare earth material, substantially increased torque-transfer capability.Owing to have employed magnetic force transfer principle, it is achieved that input, the speed-regulating function of output speed 0 ~ N%, it is greatly expanded range and the field of the present invention；Owing to have employed magnetic circuit adjustment structure, substantially reduce the power consumption performing governor motion the volume reducing adjustment actuating mechanism to greatest extent, thus it is greatly reduced the overall volume of speed regulator, not only reduce material consumption and save installing space, bringing conveniently to in-site installation construction especially.
