[background technology]
The general principle of existing permanent magnet coupling device is all utilize the relative motion between conductor rotor and p-m rotor to induce magnetic field of volution in conductor rotor, and the attempt of this magnetic field of volution hinders the motion of permanent magnetic field, thus is dragged.Utilize this mechanism, load-side is passed in a non-contact manner in power from power side.Its theoretical foundation is classical and known, and the method for Proof-Of Principle or model machine are also various, simple, but the engineer applied of maturation is still few in number so far.
First kind permanent-magnet speed governor is plate-like, regulates the distance between conductor rotor and p-m rotor, namely regulates size of gaps, and air gap is large, and the moment of torsion of transmission is little, and slippage becomes large, and show as load speed and reduce, vice versa.The Chinese invention patent announced on February 25th, 2004 is announced No. CN1140042C and is disclosed a kind of first kind adjustable magnetic coupler; No. 202696418U, the Chinese utility model patent notification number CN that on January 23rd, 2013 is announced, discloses the adjustable magnetic coupler that a kind of structure is extremely similar to above-mentioned patent.
And Equations of The Second Kind permanent-magnet speed governor is tubular.Being then the magnetic field area of contact by regulating between p-m rotor and conductor rotor, realizing the transmission of power from power side being passed to load-side, area of contact is large, then the moment of torsion transmitted is large, and slippage diminishes, and shows as load speed high, and vice versa.Chinese Patent Application No. is 200920256058.7, and Authorization Notice No. is CN201577019U, authorized announcement date be on 09 08th, 2010 patent discloses a kind of permanent-magnet speed governor, be Equations of The Second Kind permanent-magnet speed governor.It comprises: tubular conductor rotor, tubular p-m rotor and adjuster, tubular p-m rotor is in tubular conductor rotor, and independently rotate with the rotating shaft installed separately, adjuster regulates tubular p-m rotor and tubular conductor rotor at the relative position of axis direction, the active area between tubular conductor rotor and tubular p-m rotor can be changed, realize the size changing transmitting torque between tubular conductor rotor and tubular p-m rotor.
In prior art, the shortcoming that above-mentioned patent exists is all still have some deficits to the design of magnetic circuit, lower to the efficiency of magnetic energy utilization, and be provided with ferromagnetic material in conductor rotor, causes useless heat loss to increase.The above-mentioned first kind and Equations of The Second Kind permanent-magnet speed governor are all provided with radiator, but do not take the measure eliminating or reduce useless heat loss.In view of as mentioned above, the Authorization Notice No. of the present inventor is CN 203056817 U, the day for announcing be on 07 10th, 2013 patent discloses a kind of magnet dipole and the permanent magnet coupling device based on this magnet dipole, propose the solution that a kind of magnetic field is set up, but this patent does not relate to the regulative mode to magnetic field, and permanent-magnet speed governor needs to regulate the magnetic field of the dynamic useful effect in rotation, the technology related to is then more complicated.For the design of permanent-magnet speed governor, one of its core technology is to adopt more reasonably mechanical structure to realize foundation and the regulative mode in magnetic field, needs topological method make it to be achieved in conjunction with feasible and the electromagnetism optimized and mechanical structure more cleverly.But, through putting into practice and analyzing discovery, the concept of self-feeding type is introduced, permanent-magnet speed governor is had considerable technological progress, but, say from application, permanent-magnet speed governor is as a kind of emerging energy-conserving product, and coverage power scope needs from less to super large, the scope of application of rotating speed crosses over low speed to high speed, the type of cooling is from air-cooled to water-cooled, and many differences of the market demand, a few class permanent-magnet speed governor emerges.So, optimize magnetic circuit, improve transmission efficiency, reduce temperature rise; Optimization architecture, improving radiating efficiency, reduction wind is made an uproar, 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, the Chinese patent of Granted publication on the 25th was announced No. CN1140042C and was disclosed a kind of adjustable magnetic coupler in February, 2004, its governor motion is a kind of tubular end cam mechanism, the defect that its structure exists is: one, need a pair longer, to be connected on axle between unit and fixed cell perpendicular to the linkage of spindle axis, degree of regulation is lower, and floor space is larger; Its two, need two cover angular contact bearings combinations, to the length of outrigger shaft and the heavy recruitment of axle larger; Its three, displacement adjustable extent is less, complicated integral structure, and cost of manufacture is higher; Its four, prior, based on the governor motion of this structure, be not easy to take the direct safeguard measure of the mechanical type of transient response.
