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 at present conventional permanent-magnet speed governor 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.In addition conductor rotor rotate time and p-m rotor produce relative motion, permanent magnetic field produces eddy current in conductor rotor, produces amount of heat thereupon, and because 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 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 interior magnet rotor 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 magnet rotor in being connected with driven shaft, described outer magnet rotor is evenly distributed with at least one outer permanent magnet along its inner peripheral surface circumference, and the magnetic pole end face of each outer permanent magnet is vertical with outer magnet rotor end face; Described Inner magnet rotor is evenly distributed with permanent magnet at least one along its outer circumference surface circumference, the magnetic pole end face of each interior permanent magnet is vertical with interior magnet rotor end face, interior permanent magnet two magnetic pole side is fixed with iron yoke respectively, both sides are respectively provided with a magnetic conductor in addition, magnetic conductor is clipped between two iron yokes, for coordinating with iron yoke the closed magnetic loop forming and surrounded by interior permanent magnet, interior magnet rotor one end is provided with the magnetic circuit adjuster for moving each magnetic conductor vertically.Magnetic circuit adjuster controls magnetic conductor and moves the distance changing magnetic conductor and interior permanent magnet, regulates the magnetic size that in magnetic resistance size and then change, permanent magnet externally shows, the active force in changing between permanent magnet and outer permanent magnet.The removable stroke of magnetic conductor is not less than the length of iron strategic point.Concrete adjustment process: to be moved to by magnetic conductor can be formed the position of closed magnetic loop with iron yoke by magnetic circuit adjuster, when being centered around interior by interior permanent magnet, the magnetic line of force passes through smoothly through magnetic conductor, internal short-circuit, and Inner magnet rotor does not externally show magnetic; When magnetic circuit adjuster control magnetic conductor shifts out the space between two iron yokes completely, iron yoke is magnetized to the kicker magnet of corresponding polarity when magnetic conductor all shifts out internal rotor iron yoke, and the magnetic force of interior permanent magnet externally all represents, and interior magnet rotor externally shows maximum magnetic force; The process that magnetic conductor shifts out is exactly interior magnet rotor by without the change procedure of magnetic force to maximum magnetic force; Realize the change of transmitting strength by the size variation of interior magnet rotor and outer magnet rotor interaction force, thus realize speed regulation process.The quantity of outer permanent magnet can with the quantity of interior permanent magnet identical or different and both all increase and decrease in pairs according to magnetic pole (N pole, S pole magnet).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.
When the outer permanent magnet quantity of permanent magnet quantity in interior magnet rotor and outer magnet rotor is equal, can realize inputting, the speed-regulating function of output speed 0 ~ 100%; When the outer permanent magnet quantity of the permanent magnetism scale of construction in interior magnet rotor and outer magnet rotor is unequal, can realize inputting, the speed-regulating function of output speed 0 ~ N% (moment of torsion changes with N inverse proportion, maximum power constant).
This kind of mode, relative to the axial distance changing conductor rotor and p-m rotor, reduces the power consumption of magnetic circuit adjuster, improves the transmission capacity of moment of torsion.
The installation direction of inside and outside permanent magnet can have multiple, as long as the active force in ensureing between permanent magnet and outer permanent magnet is adjustable, described outer permanent magnet and the magnetic pole of interior permanent magnet are all disposed radially, and it is different that two adjacent outer permanent magnets or adjacent interior permanent magnet expose magnetic pole strength magnetic.
Both all circumferentially distribute around driven shaft.
The another kind of preferably mounting means of inside and outside permanent magnet is: described outer permanent magnet and the magnetic pole of interior permanent magnet are circumferentially arranged, two adjacent outer permanent magnets or adjacent interior permanent magnet sides adjacent magnetic pole strength magnetic different.Both all circumferentially distribute around driven shaft.
Described magnetic circuit adjuster comprise for reception control signal control magnetic conductor movement adjusting actuator.
Described adjusting actuator can be electric operator, pneumatic actuator or hydraulic actuating mechanism.In use procedure, be installed on by permanent-magnet speed governor in certain control system, pressure, flow, liquid level or other control signals are controlled system acceptance and process, are then provided to adjusting actuator, move magnetic conductor by adjusting actuator by its actuator, change the size of magnetic resistance.
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 force transfer principle, so achieve the speed-regulating function of input, output speed 0 ~ N%, greatly extend the scope of application of the present utility model and field; 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, not only reduce material consumption and save installing space, bring conveniently to in-site installation construction especially.
