Description
【Technical field】
The invention belongs to technical field of mechanical transmission, more particularly to one kind is without iron loss permanent-magnet speed governor device.
【Background technology】
The general principle of existing permanent magnet coupling device is all to utilize the relative motion between conductor rotor and p-m rotor
Magnetic field of volution is induced in conductor rotor, the magnetic field of volution attempts to hinder the motion of permanent magnetic field, so that dragged.Utilize this
Mechanism is planted, load-side is passed into power from power side in a non-contact manner.Its theoretical foundation is classical and known, and principle is tested
The method or model machine of card are also various, simple, but ripe engineer applied is still few in number so far.
First kind permanent-magnet speed governor is plate-like, and the distance between regulation conductor rotor and p-m rotor adjust air gap big
Small, air gap is big, and the moment of torsion of transmission is small, and slippage becomes big, shows as load speed reduction, vice versa.Announce within 2 25th, 2004
Chinese invention patent announce No. CN1140042C disclose a kind of first kind adjustable magnetic coupler；On January 23rd, 2013
The Chinese utility model patent notification number CN 202696418U of bulletin, discloses a kind of structure and above-mentioned patent extremely phase
As adjustable magnetic coupler.
And Equations of The Second Kind permanent-magnet speed governor is tubular.It is then to be engaged by the magnetic field adjusted between p-m rotor and conductor rotor
Area, realizes the transmission that power from power side is passed to load-side, and area of contact is big, then the moment of torsion transmitted is big, and slippage diminishes, table
Now high for load speed, vice versa.Chinese Patent Application No. is 200920256058.7, and Authorization Notice No. is
CN201577019U, authorized announcement date disclosed a kind of permanent-magnet speed governor for the patent of on 09 08th, 2010, be Equations of The Second Kind forever
Magnetic speed regulator.It includes：Tubular conductor rotor, tubular p-m rotor and adjuster, tubular p-m rotor is in tubular conductor rotor
It is interior, and independently rotated with the rotary shaft of each self installation, adjuster regulation tubular p-m rotor is with tubular conductor rotor in axis side
To relative position, thus it is possible to vary the active area between tubular conductor rotor and tubular p-m rotor, realize change tubular lead
The size of torque is transmitted between body rotor and tubular p-m rotor.
In the prior art, above-mentioned patent has the drawback that, is all that the design to magnetic circuit still has some deficits, to magnetic energy utilization
It is less efficient, and ferromagnetic material is provided with conductor rotor, cause useless heat loss to increase.The above-mentioned first kind and Equations of The Second Kind are forever
Magnetic speed regulator is provided with radiator, and the measure for eliminating or reducing useless heat loss is not taken but.In view of as described above, the present invention
The Authorization Notice No. of people is the U of CN 203056817, and the day for announcing disclosed a kind of magnet dipole for the patent of on 07 10th, 2013
Son and the permanent magnet coupling device based on the magnet dipole, it is proposed that the solution that a kind of magnetic field is set up, but the patent do not relate to
And to the regulative mode in magnetic field, and permanent-magnet speed governor needs that the magnetic field of the dynamic useful effect in rotation is adjusted, and is related to
Technology it is then increasingly complex.For the design of permanent-magnet speed governor, one of its core technology is using more reasonably mechanical structure
Realize magnetic field foundation and regulative mode, it is necessary to more cleverly topological method and combine feasible and optimization electromagnetism and machinery
Structure is allowed to be achieved.However, being found through practice and analysis, the concept of self-feeding type is introduced so that permanent-magnet speed governor has length
The technological progress of foot, still, for application, permanent-magnet speed governor is used as a kind of emerging energy-conserving product, coverage power model
Needs are enclosed from smaller to super large, and the scope of application of rotating speed is across low speed at a high speed, and the type of cooling is from air-cooled to water cooling, the market demand
Many differences, a few class permanent-magnet speed governors have emerged.So, optimize magnetic circuit, improve transmission efficiency, reduce temperature rise；Optimize frame
Structure, improves radiating efficiency, drop low wind noise, is certain demand of permanent-magnet speed governor design technological progress.
In addition, above-mentioned permanent-magnet speed governor, also has deficiency to the design of structure.Typically, on 2 25th, 2004 Granted publications
Chinese patent announce No. CN1140042C disclose a kind of adjustable magnetic coupler, its governor motion is a kind of tubular end face
Cam mechanism, its structure has a drawback in that：One is, it is necessary to which secondary longer, perpendicular to spindle axis a linkage connects
It is connected on axle between unit and fixed cell, degree of regulation is relatively low, floor space is larger；Secondly, it is necessary to two sets of angular contact bearings
Combination, the length and axle weight incrementss to outrigger shaft is larger；Third, displacement adjustable extent is smaller, complicated integral structure makes
Cost is higher；Fourth, it is prior, based on the governor motion of this structure, it is not easy to take the mechanical direct of transient response
Safeguard measure.
