Description
Technical field
The utility model relates to a kind of permanent-magnet speed governor, is specifically related to a kind of permanent-magnet speed governor of fixing magnetic gap.
Background technology
Permanent-magnet speed governor is the magnetic couple speed governing by permanent magnet, realize motor to be connected with soft (magnetic) of load, have no effect electrical network harmonic wave produce, reliability is high, and can work under high temperature, low temperature, humidity, dirt, inflammable and explosive, various adverse circumstances such as voltage instability and thunder and lightning, significantly alleviate mechanical oscillation, be widely used in electric power, iron and steel, metallurgy, petrochemical industry, the industries such as papermaking, municipal administration, naval vessel, irrigation and mining.And permanent-magnet speed governor conventional at present all realizes adjustment of rotational speed by adjustment air gap, the power consumption of magnetic circuit adjuster is large, and exist torque-transfer capability difference, assembly difficulty high, waste the shortcomings such as a large amount of rare earth resources, during outer conductor rotor turns and p-m rotor produce relative motion, permanent magnetic field produces eddy current in conductor rotor, produce amount of heat, because conductor rotor and p-m rotor must exist slippage, speed adjustable range is 0 to 98% thereupon.
Summary of the invention
For the problems referred to above, the utility model provides a kind of permanent-magnet speed governor reducing magnetic circuit adjuster power consumption, improve torque-transfer capability, reduce assembly difficulty, save rare earth resources, reduce heat generation, increase a kind of fixing magnetic gap of speed adjustable range.
Current permanent-magnet speed governor be all air gap by changing between conductor rotor and p-m rotor thus control conductor rotor cutting magnetic line number, realize torque adjustment, because this mode exists a lot of drawback, the utility model is based on the attracting principle of magnet homopolar-repulsion, heteropole, start with from the active force changed between magnet rotor and two interior magnet rotors and design new permanent-magnet speed governor, thus reach the object changing torque.
For solving the problem, the technical scheme that the utility model is taked is: a kind of permanent-magnet speed governor of fixing magnetic gap, comprise the outer magnet rotor that is 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 at least two outer permanent magnets along its inner peripheral surface circumference, each outer permanent magnet pole is disposed radially, and adjacent two outer permanent magnets to expose magnetic pole magnetic different; In a described Inner magnet rotor and second, magnet rotor to be evenly distributed with at least two first permanent magnet in permanent magnet and second along respective outer circumference surface circumference, in each, permanent magnet pole is disposed radially, and on same interior magnet rotor in adjacent two permanent magnet to expose magnetic pole magnetic different, the interior permanent magnet quantity in two on magnet rotor is identical; In second, permanent magnet exposes magnetic pole end face and is parallel to driven shaft and is provided with iron yoke, and iron yoke length is not less than the width sum of magnet rotor in a Inner magnet rotor and second, and in first, magnet rotor is within the annulus that iron yoke piece becomes; A Inner magnet rotor is provided with the magnetic circuit adjuster that in driving first, magnet rotor rotates relative to the 2nd Inner magnet rotor, for regulating in two the position relationship of permanent magnet magnetic pole of the same name on magnet rotor.
Described magnetic circuit adjuster for regulating the position relationship of permanent magnet magnetic pole of the same name in permanent magnet and second in first, and then changes the active force between outer magnet rotor and iron yoke.Adjustment process: the one Inner magnet rotor is relatively rotated by adjusting actuator to the 2nd Inner magnet rotor, when in first, in permanent magnet and second, the magnetic pole of the same name of permanent magnet is in corresponding position, iron yoke is magnetized to the kicker magnet of corresponding polarity, produce attraction or repulsive force between the principle attracting according to homopolar-repulsion heteropole and outer permanent magnet, thus make magnet rotor in second, outer magnet rotor in the same way or counter motion realize strength transmission; Active force in first in magnet rotor dependence and second between magnet rotor rotates, iron yoke so designs, outer magnet rotor only need drive magnet rotor in second to rotate by the active force produced with iron yoke, and without the need to driving magnet rotor in first to rotate, saves the moment of torsion of half.When in first, in permanent magnet and second, the synonyms pole of permanent magnet is in corresponding position, the magnetic line of force passes through smoothly through iron yoke, internal short-circuit, and iron yoke does not externally show magnetic; Outer permanent magnet does not produce active force to iron yoke, and inside and outside magnet rotor cannot realize strength transmission.In first, permanent magnet and permanent magnet in second are exactly the process that the intermolecular forces of iron yoke and outer magnet rotor changes from small to big by the corresponding corresponding process of magnetic pole of the same name that turns to of synonyms pole, thus realize the change of transmitting strength, realize speed-regulating function thus.Generally driving shaft connects mair motor, and driven shaft connects load, but both can exchange, and namely driving shaft connects load, and driven shaft connects mair motor.
Outer permanent magnet quantity on outer magnet rotor is identical with permanent magnet quantity in first on magnet rotor in first.When a Inner magnet rotor, the 2nd Inner magnet rotor are equal with outer magnet rotor permanent magnet quantity, can realize inputting, 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.When a Inner magnet rotor, the 2nd Inner magnet rotor are different from outer magnet rotor permanent magnet quantity, can realize inputting, the speed-regulating function of output speed 0 ~ N% (can raising speed or reduction of speed, moment of torsion changes with N inverse proportion, maximum power is constant).
Described magnetic circuit adjuster comprises the adjusting actuator for reception control signal.
Described adjusting actuator can be electric operator, pneumatic actuator or hydraulic actuating mechanism.In use procedure, permanent-magnet speed governor is installed in certain control system, pressure, flow, liquid level or other control signals are controlled system acceptance and process, then adjusting actuator is provided to, controlled the rotation of a Inner magnet rotor by the actuator of adjusting actuator, change the size of the intermolecular forces of outer magnet rotor and iron yoke.
The utility model, owing to have employed fixing magnetic gap structure, substantially increases the area of contact of speed regulator and reduces assembly difficulty, reduces heat and produces, increase speed adjustable range, saved rare earth material, substantially increased torque-transfer capability.Owing to have employed magnetic circuit adjustment structure, substantially reduce the power consumption the volume reducing adjustment actuating mechanism to greatest extent that perform governor motion, thus greatly reduce the overall volume of speed regulator, not only reduce material consumption and save installing space, bringing conveniently to in-site installation construction especially.
